Optometry Billing and Coding: The Complete 2026 Guide for Eye Care Practices

Optometry billing and coding is the process of translating eye exams, diagnostic testing, and vision services into CPT, ICD-10, and HCPCS codes, then managing those claims through vision and medical insurance to payment. It is also where most practices quietly lose revenue: misrouted vision-versus-medical claims, unbilled refractions, and preventable denials. This guide covers every code, modifier, and rule an optometric practice needs in 2026. 

What Is Optometry Billing and Coding?

Optometry coding is the translation of a patient encounter into standardized code sets: CPT codes for the services and procedures you performed, ICD-10 codes for the diagnoses that justified them, and HCPCS codes for materials and supplies. Optometry billing is everything that happens to those codes afterward: claim creation, scrubbing, submission to the payer, payment posting, denial follow-up, and patient collections. Coding answers what you did and why. Billing gets you paid for it.

Optometry sits in an unusual position among healthcare specialties for two reasons. First, optometrists can select from two office visit code families, the 92xxx general ophthalmological service codes reserved for eye care providers and the 99xxx evaluation and management codes used across all of medicine. Second, optometric patients routinely carry two separate insurance products, a vision plan for routine refractive care and a medical plan for ocular disease. Nearly every billing decision in an optometry practice, and nearly every denial, traces back to how well the practice navigates those two dual structures.

This guide covers both. You will learn how to credential and set fees, when to bill vision versus medical insurance, every CPT and ICD-10 code family an optometric practice uses, the modifiers that protect your reimbursement, how to appeal denials, and what changed under the 2026 Medicare Physician Fee Schedule.

How Do Optometrists Get Credentialed with Insurance Panels?

Credentialing is the payer’s verification that you are licensed, trained, and eligible to treat its members and receive payment. Submitting claims before credentialing is complete is one of the most expensive mistakes a new practice makes, because most commercial carriers will not backdate. Here is the sequence that avoids it.

 

• Obtain your NPI numbers. Every optometrist needs a Type 1 (individual) NPI. If you operate as a corporation or group, the entity needs its own Type 2 (organizational) NPI. Claims are rejected when the rendering and billing NPIs are transposed, so document which is which from day one.
• Decide your legal structure first. Sole proprietor versus corporation changes how you enroll, whose tax ID appears on claims, and how reassignment of benefits works. Get legal and accounting advice before you file a single application, because unwinding a wrong structure mid-credentialing restarts the clock.
• Complete and attest your CAQH ProView profile. Nearly every commercial carrier and most vision plans pull from CAQH. Keep your license, malpractice face sheet, DEA if applicable, and work history current, and re-attest every 120 days. An expired attestation silently stalls applications.
• Enroll with Medicare through PECOS. Individual providers use Form CMS-855I, and groups add CMS-855B with a CMS-855R to reassign benefits. Medicare is the one payer that permits retroactive billing, typically to the date it received a processable application, so establish and document that effective date before you see your first Medicare patient.
• Apply to commercial and vision panels and track everything. Typical turnaround runs 60 to 180 days depending on the carrier and state. Build a simple tracker with application date, contact, follow-up cadence, and approval date, and follow up every two weeks. Do not schedule members of a plan until the approval letter and effective date are in hand.
• Calendar your re-credentialing. Most payers re-credential every two to three years. A missed re-credentialing deadline terminates you from the panel and turns weeks of clean claims into denials.

 

If your staff cannot absorb this workload, outsourced credentialing services handle CAQH maintenance, PECOS enrollment, and panel applications for a flat per-payer fee, and they typically pay for themselves by shortening time to first reimbursement.

Vision Insurance vs Medical Insurance: Which Plan Do You Bill?

Every billing decision in optometry starts with one question: is this encounter routine or medical? The answer determines which insurance product receives the claim, and getting it wrong produces a denial from one payer and a compliance risk with the other.

Vision plans such as VSP, EyeMed, Spectera, and Davis Vision are discount and materials benefits, not medical insurance. They cover a routine refractive exam, usually once every 12 or 24 months, plus an allowance toward glasses or contact lenses. Medical insurance, including Medicare, Blue Cross Blue Shield, Aetna, Cigna, and UnitedHealthcare, covers the diagnosis, management, and treatment of ocular disease and injury.

Factor	Vision Plan	Medical Insurance
Primary purpose	Routine refractive exam and eyewear materials	Diagnosis and treatment of ocular disease and injury
Typical trigger	No complaint, or blurry vision resolved by refraction	Medical chief complaint or medical primary diagnosis
Common payers	VSP, EyeMed, Spectera, Davis Vision	Medicare, BCBS, Aetna, Cigna, UHC, Medicaid
Refraction (92015)	Bundled into the exam benefit	Not covered by Medicare; patient responsibility
Frequency limits	Every 12 or 24 months by plan design	As medically necessary with documentation
Diagnosis codes used	Z01.00, Z01.01, H52 refractive codes	Disease codes: H40, E11.3-, H25, H04.12-, others

 

The rule that decides the claim

The chief complaint and the primary diagnosis drive the claim, not the patient’s preference and not which plan pays better. A patient who presents for a routine exam with no complaints and leaves with a refractive diagnosis is a vision plan claim. A patient who presents with flashes and floaters, or whose routine exam uncovers diabetic retinopathy that becomes the focus of the visit, generates a medical claim even if they booked a routine appointment. Steering a medical encounter to a vision plan because the copay is lower, or a routine encounter to medical insurance because it reimburses more, is misrepresentation, and it is one of the fastest routes to a payer audit.

Can you bill vision and medical insurance on the same day?

Yes, when the encounter legitimately contains both services and the plans permit coordination of benefits. The standard structure bills the medical exam and any medically necessary testing to the medical carrier with the medical diagnosis, and bills the refraction, and only the refraction, to the vision plan. Some vision plans also offer coordination arrangements that apply the vision benefit to the patient’s medical cost share. Three rules keep same-day billing clean: never bill the same service to both payers, document the medical and refractive components separately in the record, and set patient expectations at check-in so the medical copay and refraction fee do not arrive as a surprise at checkout. When a patient carries both products, verify both eligibility before the visit; more same-day denials come from unverified vision plan eligibility than from any coding error.

Optometry CPT Codes: The Complete List by Category

Accurate coding is the backbone of optometry billing. Each code represents a service, and incorrect coding leads directly to revenue loss.

92xxx vs 99xxx: Which Code Set Should You Use? 

Factor	92xxx Eye Codes	99xxx E/M Codes
Who can use them	Eye care providers only (ODs and MDs/DOs in eye care)	All physicians and qualified providers
Exam types allowed	Routine and medical exams	Medical exams only
Code selection basis	Comprehensive vs intermediate service definitions	Medical decision making or total time (2021 guidelines)
Levels	Two per patient status: 92002/92004 new, 92012/92014 established	Four billable levels each: 99202-99205 new, 99212-99215 established
Payer restrictions	Some medical carriers now limit 92xxx to routine care	Universally accepted for medical encounters
Typical use	Annual comprehensive exams, anterior segment follow-ups	Problem-focused medical visits, complex disease management

Eye Exam and Evaluation Codes

The 92xxx family has two levels. Comprehensive codes 92004 (new patient) and 92014 (established patient) describe a medical examination and evaluation with initiation or continuation of a diagnostic and treatment program, typically including a dilated or equivalent retinal evaluation, and are generally billed no more than once per patient per year. Intermediate codes 92002 (new) and 92012 (established) describe evaluation of a new or existing condition with a less than comprehensive service, and fit anterior segment problems and follow-up visits; 92012 can be reported multiple times per year, for example at glaucoma checks. The distinction between intermediate and comprehensive must be supported by the documented exam elements, not by habit. 

On the 99xxx side, levels are selected by medical decision making or total time under the 2021 guidelines: most new-problem visits support moderate MDM, follow-ups support low, and level 5 belongs to sight-threatening presentations such as retinal artery occlusion. Whichever family you choose, train providers to document every performed element, because the record, not the superbill, sets the billable level. 

How to Bill Refraction (CPT 92015)

CPT 92015 is the determination of refractive state, the measurement that produces the eyeglass prescription. It is billed once per encounter regardless of technique, whether phoropter, autorefractor-assisted, or trial frame, and it is separately reportable alongside both 92xxx and 99xxx office visit codes.

 

Here is the part that surprises new graduates every year: Medicare never covers refraction. It is a statutory exclusion under the eye exam provisions of the Social Security Act, in the same category as eyeglasses themselves, not a service denied for lack of medical necessity. That distinction matters for how you handle it on the claim.

 

• Append modifier GY to 92015 on Medicare claims. GY identifies a statutorily excluded service and generates an automatic denial you can forward to a supplemental payer or use to bill the patient directly.
• An ABN is not required for refraction because Advance Beneficiary Notices apply to services that are covered but expected to be denied as not medically necessary. Many practices still issue a voluntary ABN as a courtesy notice, which is permitted and does reduce front-desk disputes, but it is not a payment condition for a statutory exclusion.
• Collect the refraction fee at checkout. Typical fees run $25 to $60 depending on the market. Post it as patient responsibility on the day of service; billing statements for a $40 refraction lose money.
• Commercial medical plans vary. Some follow Medicare and exclude refraction, some bundle it, a few reimburse it. Verify per plan rather than assuming, and load the answer into your practice management system by payer so front desk quotes are consistent.
• Vision plans bundle refraction into the routine exam benefit. Never bill 92015 separately to a vision plan on top of the contracted exam, and never bill the patient for it when the vision plan exam includes it.

Practices that fail to charge for refraction, or that write it off to avoid the conversation, forfeit one of the most reliable revenue lines in the clinic. At $40 per refraction and ten refractions a day, an office recovers roughly $100,000 a year simply by billing the service correctly and collecting it at the desk.

Surgical Co-Management Billing (Modifier 55) 

Optometrists do not bill surgery, but they routinely bill the post-operative care of surgery under co-management arrangements, most often after cataract surgery. The mechanics are specific and unforgiving. Use the date of surgery as the date of service, append modifier 55 (post-operative management only) plus RT or LT to the same surgical CPT and diagnosis codes the surgeon used, and put the surgeon in box 17 with their NPI in 17b. Box 19 carries the assumed-care start date, end date, and number of days of care within the 90-day global period. 

When the second eye is operated on within the global period of the first, add modifier 79 to the second eye’s claim so it is not denied as a duplicate. Maintain a co-management calendar that tracks each patient’s global period, because a visit for an unrelated problem during that window needs modifier 24 on the office visit to be paid at all. 

Diagnostic Testing Codes: OCT, Fundus Photography, and Visual Fields

Special testing is where optometry practices earn a meaningful share of medical revenue and where auditors look first, because every test must stand on its own medical necessity. Three rules govern all of the codes below: there must be an order in the record, the test must be justified by a covered diagnosis under the payer’s policy, and any code that includes interpretation and report requires a distinct I&R documented in its own section of the chart, not buried in the assessment and plan.

CPT	Description	Billing Notes
92133	Scanning computerized ophthalmic diagnostic imaging (SCODI), optic nerve (glaucoma OCT)	Bilateral. Never billable with 92134 on the same date. Frequency limited by glaucoma severity under most LCDs.
92134	SCODI, retina (macular OCT)	Bilateral. Used for AMD, diabetic macular edema, retinal disease. NCCI bundles it with fundus photography on the same date.
92132	SCODI, anterior segment	Bilateral. Narrow coverage; verify payer policy before routine use.
92250	Fundus photography with interpretation and report	Bilateral, one fee for one or both eyes. Requires pathology except documented baselines for high-risk medications such as Plaquenil.
92081 / 92082 / 92083	Visual field examination: limited, intermediate, threshold	Bilateral. Match the level to necessity; 92083 for glaucoma threshold testing. I&R required.
92201 / 92202	Extended ophthalmoscopy with retinal drawing: peripheral / posterior pole	Replaced 92225 and 92226 in 2020. Requires a detailed drawing and interpretation, not a checkbox.
92020	Gonioscopy	Bilateral. Standard in glaucoma and narrow angle workups; document angle findings per eye.
76514	Corneal pachymetry	Typically payable once per lifetime per patient for glaucoma risk assessment under Medicare policy.
92285	External ocular photography	Anterior segment documentation: lid lesions, corneal disease progression.

 

The same-day trap to train your staff on: 92133 and 92134 are mutually exclusive on a single date of service because CPT defines them as distinct anatomic applications of one imaging family. When a glaucoma suspect also has macular findings, image both but bill the code that addresses the primary reason for the encounter, and bring the patient back for the second study when it is separately necessary. Likewise, when NCCI bundles fundus photography with a posterior segment OCT on the same date, bill the test that answers the clinical question rather than reflexively unbundling with modifier 59, which is the exact pattern payer analytics are built to flag.

Contact Lens Fitting and Management Codes

Contact lens services are separately reportable from the office visit, and the fitting fee belongs to the professional service of designing, evaluating, and finalizing the lens, not to the materials. Materials are reported with HCPCS V-codes such as V2500 through V2531 when a plan covers them.

CPT	Description	When to Use
92310	Prescription and fitting of contact lenses, both eyes, other than aphakia	The standard elective soft or GP lens fit. Vision plans price this by lens complexity tier.
92311 / 92312	Contact lens fitting for aphakia, one eye / both eyes	Post-cataract patients without an IOL; billable to medical insurance.
92313	Corneoscleral lens fitting	Scleral lens design for irregular corneas and severe ocular surface disease.
92071	Fitting of contact lens for treatment of ocular disease	Bandage lens for corneal abrasion, recurrent erosion, post-procedure protection. Often bundled into same-day procedures; verify per payer.
92072	Fitting of contact lens for management of keratoconus, initial fitting	The keratoconus medical fit. One of the better reimbursed fitting codes; subsequent visits use established patient exam codes.

 

Medically necessary contact lenses, for keratoconus, corneal ectasia, aphakia, aniseikonia, and severe dry eye, follow completely different rules than elective wear. Some medical carriers and most vision plans cover them under defined criteria, and reimbursement can run into four figures per year for scleral programs, but coverage varies enough that the safest workflow is written verification before fitting plus a signed financial agreement making the patient responsible if the plan denies. Set that expectation before the fitting, not at the collections call.

Telehealth and Remote Imaging Codes for Optometry

Telehealth in eye care splits into two families: synchronous visits, where you and the patient interact in real time, and asynchronous remote imaging, where retinal images are captured in one location and interpreted in another.

• Synchronous visits use the standard 99202 through 99215 E/M codes with modifier 95 and the correct place of service, POS 10 when the patient is home and POS 02 elsewhere. They fit follow-ups where the exam component is not the point: reviewing outside imaging, medication checks, triaging red eye to determine urgency.
• Online digital E/M codes 99421 through 99423 cover asynchronous portal-based evaluations, cumulative over seven days, initiated by the patient.
• Remote retinal imaging uses 92227 (screening for retinal disease, remote staff review), 92228 (remote physician or QHP interpretation for active disease management), and 92229 (point-of-care automated analysis, the AI diabetic retinopathy screening code). These are how diabetic retinopathy screening programs in primary care settings get read and paid.

For 2026, CMS simplified how services are added to the Medicare telehealth list, permanently adopted virtual direct supervision through real-time audio-video, and raised the originating site facility fee to $31.85. Commercial payers still set their own telehealth rules, so verify parity per plan rather than extrapolating from Medicare.

Common Optometry ICD-10 Codes and Laterality Rules

ICD-10 tells the payer why the service happened, and in eye care the diagnosis carries structural information the claim lives or dies on: laterality, severity staging, and in glaucoma a seventh character for stage. Coding to the highest specificity available is not a style preference; unspecified codes are a leading driver of medical necessity denials and a known audit flag.

Laterality is embedded in most ocular codes: 1 designates the right eye, 2 the left, 3 bilateral, and 9 unspecified. Use 9 only when the record genuinely cannot support a side, which in eye care should be almost never.

Category	Key Codes	Notes
Routine encounter	Z01.00, Z01.01	Encounter for exam of eyes and vision without / with abnormal findings. Pair with the refractive finding.
Refractive error	H52.11-H52.13 myopia, H52.01-H52.03 hypermetropia, H52.201-H52.203 astigmatism, H52.4 presbyopia	The workhorse codes on vision plan claims.
Cataract	H25.11- age-related nuclear, H25.81- combined forms, H26.9 unspecified	Stage and type support surgical referral and co-management claims.
Glaucoma	H40.11X- primary open-angle with stage, H40.001- open angle suspect, H40.06- primary angle closure without damage	Seventh character stages POAG: 1 mild, 2 moderate, 3 severe, 4 indeterminate. The stage must match your OCT and field billing frequency.
Diabetic retinopathy	E11.319, E11.321-E11.359 series with laterality, E11.9	Code the diabetes and the retinopathy together; severity and macular edema status are built into the code.
Dry eye / ocular surface	H04.121-H04.123 dry eye by eye, H02.881- meibomian gland dysfunction, H16.22- keratoconjunctivitis sicca	Supports the dry eye service line including 92071 and amniotic membranes.
Macular degeneration	H35.31- nonexudative with stage, H35.32- exudative with stage	Staging characters drive OCT frequency justification.
Monitoring codes	Z79.899 high-risk medication, T37.2X5A antimalarial adverse effect, M06.09 rheumatoid arthritis	The Plaquenil exam triad: systemic disease + Z79.899, adding the T-code only when toxicity is present.

 

New and revised ICD-10 codes take effect every October 1, and CPT changes every January 1. Put both dates on the practice compliance calendar and re-verify your top 25 diagnosis codes each October, because superseded codes are rejected outright by most clearinghouses.

Routine vs Medical Eye Exams: How the Diagnosis Drives the Exam 

The vision-versus-medical decision covered earlier determines where the claim goes; this decision determines what the exam itself looks like and how it is coded. The case history is identical either way, because it happens before the exam type is established. The divergence comes next. A routine refractive exam involves little or no medical decision making, and many doctors perform a fixed battery of elements on every patient. A medical exam must not work that way: you select and perform only the elements necessary to diagnose and treat the presenting problem, because carrying a routine template into a medical encounter artificially inflates the coded level. 

 

Medical decision making then sets the visit level. In practice, most optometric encounters resolve to two tiers: low complexity for established-problem follow-ups and moderate complexity for new problem presentations, with high complexity reserved for multiple or sight-threatening problems. Also remember that blurry vision is a complaint, not a diagnosis; when the workup reveals a medical cause, the encounter is medical regardless of what the patient booked. 

Optometry Billing Modifiers Explained 

Modifiers tell the payer the circumstances of a service: which eye, which lid, whether a visit was separate from a procedure, whether care fell inside a surgical global period. Missing or wrong modifiers are one of the top denial drivers in eye care, so build validation into your claim scrubbing before submission.

Modifier	Meaning	Typical optometry use
RT / LT	Right / left eye	Unilateral procedures such as foreign body removal 65222
E1 / E2 / E3 / E4	Upper left / lower left / upper right / lower right lid	Punctal occlusion 68761, lid procedures
24	Unrelated E/M during a post-operative global period	Office visit for a new problem during cataract co-management
25	Significant, separately identifiable E/M on the same day as a procedure	Exam plus same-day punctal plugs
51	Multiple procedures, same session	Second and subsequent punctal plugs
55	Post-operative management only	Cataract surgery co-management
59	Distinct procedural service	Overriding an NCCI bundle only when genuinely separate; the most audited modifier on this list
79	Unrelated procedure during a global period	Second eye cataract co-management within 90 days of the first
GY	Statutorily excluded service	Refraction 92015 on Medicare claims
95	Synchronous telehealth	Virtual follow-up visits

Why Optometry Claims Get Denied and How to Appeal

A denial is not a dead claim; it is a claim with a correctable defect, and the payer tells you the defect in code. Every remittance carries Claim Adjustment Reason Codes (CARCs) and Remittance Advice Remark Codes (RARCs) that identify exactly why payment was reduced or refused. A billing team that works denials by reason code, rather than re-submitting blind, recovers most of them.

The six denial reasons that dominate optometry

• Eligibility and coverage: the patient’s vision or medical plan was inactive, or the routine benefit was already used this cycle. Prevented entirely by real-time eligibility checks before the visit.
• Coordination of benefits: the claim went to the wrong payer first, common when patients carry both vision and medical products.
• Missing or wrong modifiers: bilateral testing billed twice, a global period visit without modifier 24, same-day exam and procedure without modifier 25.
• Medical necessity: the diagnosis on the claim does not support the test under the payer’s coverage policy, the classic unspecified-code OCT denial.
• Timely filing: Medicare allows 12 months from the date of service, but commercial and vision plan windows can be as short as 60 to 90 days, and timely filing denials are the hardest category to overturn.
• Credentialing gaps: the rendering provider was not effective with the plan on the date of service.

The appeal workflow

For Medicare, the first appeal level is a redetermination, filed within 120 days of the remittance date, followed if needed by reconsideration through a Qualified Independent Contractor and three further levels up to federal court, though optometric appeals almost always resolve at the first two. For commercial payers, the EOB states the appeal window and address; most allow 180 days for a first-level appeal. A winning appeal packet is short and surgical: the claim, the remittance showing the CARC, the chart note and order proving the service and its necessity, the relevant payer policy language, and a one-page letter connecting them. Track two metrics monthly to know whether denials are under control: first-pass acceptance rate, which a healthy practice keeps at 95 percent or better, and overall denial rate, which should sit in the single digits. When either drifts, the reason codes will tell you which upstream process broke.

In-House Billing vs Outsourced Optometry Billing

Every practice eventually asks whether billing belongs inside the building. There is no universal answer, but there is a clean way to run the math.

An in-house arrangement means a trained biller on payroll, typically $45,000 to $60,000 plus benefits, plus clearinghouse and software costs, plus the hidden cost that matters most: what happens to your AR when that one person is on vacation, out sick, or gives notice. In exchange you get proximity, same-hallway communication with the front desk, and direct control over patient billing conversations.

An outsourced arrangement typically prices at 4 to 8 percent of collections, scales with volume in both directions, and buys you a team rather than a person, which removes the single-point-of-failure risk and usually brings deeper payer-specific expertise in areas like vision plan coordination and Medicare appeals. The tradeoffs are distance from your front desk and the need to manage the vendor with the same KPIs you would use internally.

• Outsourcing tends to win when: the practice bills under roughly $1.5 million in collections and cannot keep a skilled biller fully utilized, denial rates or 90-day AR are drifting up, the owner is doing billing after clinic hours, or a departure just exposed how much institutional knowledge lived in one head.
• In-house tends to win when: volume supports a full billing team of two or more, the practice has strong internal process discipline, and leadership actually reviews first-pass acceptance, denial rate, and AR aging monthly.

Whichever direction you choose, hold it to the same standard: 95 percent or better first-pass acceptance, 90-day-plus AR at roughly 20 percent of total AR or lower, and denials worked within one week of the remittance. A billing operation that cannot report those three numbers, internal or external, is the wrong billing operation.

Documentation Requirements: The Backbone of Clean Claims

Medical necessity must be clearly established through the chief complaint, history, and clinical findings. Exam documentation should capture the elements performed: visual acuity, intraocular pressure, anterior and posterior segment findings as relevant to the visit. Every diagnostic test needs an order in the record, and tests that include interpretation and report, such as OCT and visual fields, need that I&R documented in its own section of the chart, not buried in the assessment and plan. For procedures, document the indication, technique, laterality, and outcome.

Solution strategy: use EHR templates built for eye care to standardize documentation, but review them yearly so templated language never outruns what was actually performed. 

Prior authorization in optometry 

Prior authorization touches optometry less than surgical specialties, but where it applies, skipping it produces automatic denials no appeal can fix. The common triggers are amniotic membrane placement (65778), some in-office injections, medically necessary contact lens programs, and certain imaging under Medicare Advantage plans. Build authorization into scheduling: verify the requirement at booking, submit the clinical documentation, and confirm the authorization number is on file before the patient sits in the chair. 

How Do You Avoid an Optometry Billing Audit?

Payers flag outliers statistically before a human ever reads a chart, so audit prevention is mostly about not looking like an outlier while documenting like you expect one. The common triggers are overuse of level 4 and 5 E/M codes, billing the same exam code for every patient, ordering diagnostic tests without documented medical necessity, billing services not supported by the record, and an E/M code distribution that deviates sharply from peers in your area.

The reason practices fail audits is almost always documentation, not fraud: the service was performed but the record does not prove it. If it is not written in the chart, you receive no credit for it. Fail an audit for billing errors and you refund the overpayments and invite further review; fail for fraud and the exposure becomes civil and criminal.

Prevention is a system, not a scramble. Run an internal chart audit quarterly on a random claim sample. Train providers and staff on coding changes every January and October. Use claim scrubbing software to catch modifier and bundling errors before submission. And review your own E/M utilization curve annually against CMS specialty data, because that is exactly the comparison the payer is running.

2026 Optometry Billing Updates You Need to Know

The CY 2026 Medicare Physician Fee Schedule brought the most structural change to physician payment in a decade, and several pieces landed directly on optometry.

• Two conversion factors now exist. For the first time, Medicare pays under separate conversion factors: $33.5675 for qualifying participants in advanced alternative payment models and $33.4009 for everyone else, increases of 3.77 percent and 3.26 percent over the 2025 factor of $32.35. Most optometrists fall under the non-QP factor.
• A temporary 2.5 percent increase is baked in for 2026 only, passed by Congress in mid-2025. Because it is a one-year provision, build 2027 fee projections without it.
• A negative 2.5 percent efficiency adjustment now applies to the work values of most non-time-based services. E/M visits and telehealth-list codes are exempt, but procedure and testing codes are not, which is why some diagnostic and surgical allowables fell even as the conversion factor rose. Check your top 20 codes in the CMS Physician Fee Schedule Lookup Tool rather than assuming an across-the-board raise.
• MIPS holds at a 75-point performance threshold, and the low-volume exclusion remains: bill Medicare $90,000 or less, or see 200 or fewer Medicare patients, or provide 200 or fewer covered services in the determination period, and you are excluded from reporting, receiving the standard fee schedule with no adjustment either way.
• Telehealth flexibilities became permanent, including virtual direct supervision, and the originating site facility fee rose to $31.85.
• Annual code cycles continue: new ICD-10 codes took effect October 1, 2025, and the next set lands October 1, 2026; CPT changes arrive January 1 each year.

Why UControl Billing Is the Strategic Advantage Your Practice Needs

In a field where precision determines profitability, having the right billing partner is no longer optional. It is essential.

UControl Billing stands apart by combining deep eye care billing expertise with advanced revenue cycle technology. Unlike generic billing companies, it understands the problems that actually drain optometry revenue: vision versus medical claim routing, unbilled refractions, co-management mechanics, diagnostic testing frequency rules, and the vision plan coordination errors that generic billers miss entirely. 

What truly differentiates UControl Billing is its proactive approach. Instead of reacting to denials, it prevents them. Every claim is optimized before submission, every code validated, and every documentation gap addressed. This results in significantly higher first-pass acceptance rates and faster reimbursements.

Beyond accuracy, UControl Billing focuses on growth. By identifying undercoding, recovering lost revenue, and streamlining workflows, it transforms billing into a powerful revenue driver.

For healthcare facilities aiming to scale, improve cash flow, and eliminate billing stress, UControl Billing delivers not just services but a measurable financial impact.

Turning Billing Complexity Into Revenue Opportunity

Optometry billing and coding is complex, but it does not have to be chaotic. With the right strategies, tools, and expertise, it becomes a powerful engine for revenue growth.

From mastering CPT codes and modifiers to optimizing documentation and preventing denials, every step plays a role in financial success. Practices that invest in precision and partner with experts position themselves for long-term stability and growth.

The question is no longer whether you can afford to optimize your billing. It is whether you can afford not to.

FAQs

What is the difference between 92014 and 99214?

Both describe an established patient medical visit, but 92014 is an eye-specific comprehensive ophthalmological code selected by service definition, while 99214 is an E/M code selected by medical decision making or time. Reimbursement differs by payer, and some medical carriers now restrict 92xxx codes to routine care, so verify per plan before defaulting to either.

Does Medicare cover refraction (92015)?

No. Refraction is statutorily excluded from Medicare coverage and is always patient responsibility. Full billing mechanics, including the GY modifier, are covered in the refraction section above.

Can you bill vision and medical insurance for the same visit?

Yes, when the encounter genuinely contains both a medical component and a refraction and the plans coordinate benefits. The rules are covered in the vision versus medical insurance section above.

How often can you bill OCT for glaucoma? 

Frequency follows disease stage under most Medicare coverage policies: roughly annually for suspects and mild disease, twice yearly for moderate, and severe-stage disease generally does not support OCT because end-stage progression cannot be measured. Always match frequency to your documented staging.

What is the timely filing limit for optometry claims? 

Medicare allows 12 months from the date of service. Commercial and vision plan windows vary widely and can be as short as 60 to 90 days, so confirm each contracted payer’s deadline and file within it, because timely filing denials are rarely overturned.

How long does optometrist credentialing take?
