Does Aetna Cover Dermatology? Coverage, Billing & Reimbursement Guide for Providers 

Yes. Aetna covers medically necessary dermatology on most of its plans, including commercial HMO and PPO, Medicare Advantage, and Medicaid managed care plans in the states where Aetna runs them. Whether a specific claim gets paid comes down to three things: the plan type, whether the service meets Aetna medical necessity criteria, and whether your front desk clears the referral and prior authorization rules before the date of service. Cosmetic dermatology is not covered.

This guide is built for the people who handle dermatology medical billing. Below you will find the plan rules, the CPT ranges Aetna recognizes, the medical necessity criteria pulled from Aetna Clinical Policy Bulletins, the prior authorization workflow, and the documentation that keeps claims off your denial list. The aim is to get paid on the first pass.

Plan Types and How They Affect Dermatology Coverage?

Aetna offers several plan structures, each with different rules for accessing dermatology care. Understanding these differences helps you verify patient benefits correctly and set proper expectations at the front desk.

HMO Plans

HMO plans typically require the patient to select a primary care physician. That PCP must provide a referral before the patient can see a dermatologist. Without that referral, Aetna will deny the claim, and the patient may be responsible for the full cost of the visit. HMO plans also have stricter network requirements. The patient generally must see in-network providers for coverage to apply, except for emergency services.

PPO Plans

PPO plans offer more flexibility. Patients can see a dermatologist directly without a PCP referral. However, using in-network providers costs less than going out-of-network. The claim still requires prior authorization for certain services, but the referral access barrier has been removed.

EPO Plans

EPO plans fall somewhere in between. These plans generally do not require referrals, but they require the patient to stay within the network for coverage. Out-of-network services are typically not covered at all except in emergencies. Checking network status before scheduling is essential.

Medicare Advantage PPO Plans

Medicare Advantage PPO plans from Aetna generally do not require a PCP or a referral to see a specialist. This is a significant difference from HMO plans. However, patients can choose any provider who accepts Medicare and the plan’s terms. In-network care costs less, but out-of-network care is still covered at a higher patient cost share.

Medicaid Managed Care Plans

Medicaid managed care plans vary by state. Aetna operates Medicaid plans in several states under names like Aetna Better Health. These plans have their own specific coverage criteria, prior authorization requirements, and referral rules. Providers should check the specific state’s provider manual for details.

Telehealth coverage has expanded significantly. Starting January 1, 2026, all Aetna plans offer a $0 copay for Teladoc virtual primary care visits. Some plans also cover dermatology consultations through telehealth. Coverage details vary by plan, so verifying benefits before the visit is recommended.

What dermatology services does Aetna pay for?

Aetna Clinical Policy Bulletins define medical necessity service by service. The table maps common dermatology services to the CPT ranges Aetna recognizes and the condition that has to be met. The subsections under it spell out the criteria your documentation has to support.

CPT ranges follow the current Aetna Clinical Policy Bulletins. Confirm code level coverage and any plan specific edits before you submit.

Cosmetic Versus Medically Necessary: The Critical Distinction

Aetna does not cover cosmetic services. The distinction between cosmetic and medically necessary is not always clear, and this is a common source of insurance claim denials.

• Cosmetic services not covered. Aetna considers the following dermatology services cosmetic and not covered. Dermabrasion for scar revision or removal of acne scars. Chemical peels for acne scarring, melasma, skin wrinkling, or lentigines. Laser treatment for acne scarring, pearly penile papules, or rhinophyma. Laser hair removal for cosmetic reasons. Scar injection or any other treatment to smooth or reduce visible acne scarring.
• The documentation difference. For medically necessary services, the documentation must clearly link the service to a specific medical condition and the necessity criteria in Aetna’s Clinical Policy Bulletins. For cosmetic services, the patient is responsible for payment, and the claim should not be submitted to Aetna.
• When there is ambiguity, the documentation should err on the side of specificity. A note that says “patient requested removal of mole” does not support medical necessity. A note that says “mole on right cheek has changed color and shape over past three months, with asymmetric borders, concerning melanoma” does support medical necessity for biopsy and removal.

Covered Dermatology Services: What Aetna Pays For?

Aetna publishes Clinical Policy Bulletins that define medical necessity for dermatology services. These bulletins are the final word on what Aetna considers covered. 

Here are the key services and their coverage rules.

Skin Lesion Removal

Benign skin lesion removal is covered when specific medical-necessity criteria are met. Aetna considers removal medically necessary under any of the following conditions. A biopsy suggests or indicates premalignancy or malignancy. The lesion is subject to recurrent trauma or irritation due to its anatomic location, such as along a bra line or waistband. 

The lesion appears premalignant due to coloration, changes in appearance or size, especially in patients with a personal or family history of melanoma. The lesion causes symptoms such as bleeding, burning, intense itching, or irritation. Evidence of inflammation exists, including edema, erythema, or purulence. The lesion is infectious, such as warts. The lesion restricts vision or obstructs a body orifice.

Benign Lesion Removal

For benign lesion removal, Aetna covers the following CPT code ranges. Shaving of epidermal or dermal lesions uses codes 11300 through 11313. Excision of benign lesions uses codes 11400 through 11446. Destruction of benign lesions other than skin tags is coded as 17110 and 17111. Removal of skin tags is coded as 11200 and 11201.

Aetna does not cover removal of benign lesions for cosmetic reasons alone. If the only reason for removal is patient preference without any medical-necessity criteria, the service is considered cosmetic and not covered.

Actinic Keratosis Treatments

Actinic keratosis treatments are covered under specific guidelines. Aetna considers destruction of actinic keratoses medically necessary using cryosurgery with liquid nitrogen or topical agents including diclofenac, imiquimod, ingenol mebutate gel, or 5-fluorouracil with or without tretinoin cream.

For patients who fail to respond adequately to topical imiquimod, 5-FU, or cryosurgery, Aetna considers additional treatments medically necessary. These include chemical peels, dermabrasion, laser therapy, and photodynamic therapy with aminolevulinic acid and blue or red light.

Curettage or excision is covered when squamous cell carcinoma is suspected and submission of a specimen for histological analysis is needed.

Laser Treatment for Psoriasis

Laser treatment for psoriasis is covered under specific criteria. Aetna considers excimer and pulsed dye laser treatment medically necessary for patients with mild-to-moderate localized plaque psoriasis affecting 10 percent or less of their body area. The patient must have failed to respond adequately to at least 3 months of topical treatments, including at least 3 of the following: anthralin, corticosteroids, keratolytic agents, retinoids, tar preparations, or vitamin D derivatives.

Aetna generally considers no more than 13 laser treatments per course and three courses per year as medically necessary. If the patient fails to respond to an initial course of laser therapy, as documented by a reduction in the Psoriasis Area and Severity Index score or another objective response measure, additional courses are not considered medically necessary.

Laser treatment for other forms of psoriasis, beyond plaque psoriasis, is considered experimental and not covered.

Dermabrasion And Chemical Peels

Dermabrasion and chemical peels have limited coverage. Aetna considers dermabrasion medically necessary for the removal of superficial basal cell carcinomas and precancerous actinic keratoses when conventional methods of removal, such as cryotherapy, curettage, and excision, are impractical due to the number and distribution of lesions, and the patient has failed a trial of 5-fluorouracil or imiquimod, unless contraindicated.

Medium and deep chemical peels are covered for actinic keratoses and other pre-malignant skin lesions when the patient has 15 or more lesions, making individual treatment impractical, and has failed topical 5-FU or imiquimod unless contraindicated.

Chemical peels for active acne, melasma, skin wrinkling, and lentigines are considered cosmetic and not covered. Dermabrasion for scar revision or acne scar removal is also considered cosmetic.

Acne Surgery

Acne surgery is covered for specific indications. Aetna considers acne surgery medically necessary for marsupialization, opening or removal of multiple milia, comedones, cysts, and pustules for treatment of acne vulgaris. Intralesional corticosteroid injection is covered for inflammatory nodulocystic acne and fcne inversa. Surgical treatment including incision, drainage, punch debridement, unroofing, and excision is covered for acne inversa stages I through III.

Laser Hair Removal

Laser hair removal has very limited coverage. Aetna considers laser hair removal medically necessary only for recurrent pilonidal cyst and for active acne keloidalis nuchae that is poorly responsive to medical therapy. Laser hair removal for cosmetic reasons is not covered.

Grenz Ray Therapy

Grenz ray therapy is not covered for any dermatologic condition. Aetna considers this treatment experimental, investigational, or unproven due to inadequate evidence in the peer-reviewed medical literature.

Prior Authorization Requirements for Dermatology

Many dermatology services and medications require prior authorization from Aetna before they are delivered. Submitting claims without required prior authorization will result in denial.

Medications Requiring Prior Authorization

Specialty dermatologic medications almost always require prior authorization. For example, Enbrel for plaque psoriasis requires prior authorization and documentation of failure of conventional therapy. Aetna places Enbrel on Tier 5, the specialty tier, across its 2026 formularies. This means higher copays, typically 25 percent coinsurance, and the medication must be dispensed through CVS Specialty.

• For plaque psoriasis, Aetna requires one of the following criteria to approve Enbrel. Crucial body areas affected, including hands, feet, face, neck, scalp, or genitals, 10% or more of body surface area affected. Three percent or more of body surface area affected, plus failed phototherapy or systemic therapy such as methotrexate, cyclosporine, or acitretin.
• Opzelura for atopic dermatitis also requires prior authorization. Aetna requires documented failure of at least one medium- to high-potency topical corticosteroid for at least 28 days. The patient must be age 12 or older and non-immunocompromised. Short-term, non-continuous use is intended. Opzelura is classified as a preferred brand medication on Aetna’s formulary, meaning it has higher copays than generics but lower costs than non-preferred brands.

Procedures Requiring Prior Authorization

While routine office visits and simple biopsies generally do not require prior authorization, certain procedures do. Laser treatments for psoriasis, photodynamic therapy, and other advanced dermatologic procedures typically require prior authorization. Providers should check Aetna’s precertification list before scheduling these services.

• Step therapy requirements. Many dermatologic medications require step therapy. This means the patient must try and fail preferred alternatives before Aetna will approve the requested medication. For Opzelura, Aetna requires documented failure of topical corticosteroids. For Enbrel, Aetna requires documented failure of methotrexate or other conventional therapy unless contraindicated.
• Prior authorization submission. The fastest way to submit a prior authorization request is through Aetna’s provider portal. For medications managed by CVS Caremark, providers can also fax requests to 1-877-309-8077. Required documentation includes a completed prior authorization form, a medical necessity letter, clinical notes documenting prior treatment failures, disease activity measures (when applicable), and relevant lab results, including tuberculosis screening, for biologic medications.
• Decision timelines. Standard prior authorization decisions typically take 30 to 45 days for medications. Expedited reviews for urgent cases take 72 hours. For procedure authorizations, timelines vary by service type and urgency.
• Appeals process. If a prior authorization request is denied, providers have the right to appeal. For Aetna commercial plans, internal appeals must be filed within 180 days of the denial. For Medicare Advantage plans, different timelines may apply. For Medicaid plans, state-specific external review rights exist. Documentation supporting medical necessity should be included with every appeal.

Referral Requirements by Plan Type

Referral requirements vary significantly by plan type. Getting this wrong at the front desk leads to claim denials and patient frustration.

• For HMO plans, the patient must have a referral from their primary care physician to see a dermatologist. The referral must be active and valid on the date of service. The referral must match the diagnosis being treated. Without a referral, the claim will be denied, and the patient may be billed for the full cost of the service.
• For PPO plans, no referral is required. Patients can schedule directly with a dermatologist. However, the patient’s cost share may be higher for out-of-network providers.
• For EPO plans, referral requirements vary by the specific plan. Some EPO plans do not require referrals, but they require the patient to stay strictly in network. Out-of-network services are generally not covered at all, except in emergencies.
• For Medicare Advantage PPO plans, Aetna generally does not require a referral to see a specialist. This is a key difference from commercial HMO plans. Patients can see any provider who accepts Medicare and the plan’s terms, though in-network providers cost less.
• For Medicaid managed care plans, referral requirements vary by state. Providers should check the specific state’s provider manual. In Pennsylvania, for example, Aetna Better Health may have different requirements than commercial plans. 

Documentation Requirements for Clean Claims

Proper documentation is the foundation of clean claims and successful prior authorization requests. For dermatology services billed to Aetna, specific documentation elements are essential.

• For lesion removal claims. The medical record must document the specific location of each lesion. It must describe the appearance and the reason for removal, referencing the medical-necessity criteria in Aetna’s Clinical Policy Bulletin. The specific technique used, shave, excision, or destruction, must be noted. The size of the lesion must be recorded for excision codes. If a biopsy was performed, the pathology report must be included in the record.
• For actinic keratosis treatment. The record must document the number and location of lesions treated. It must note previous treatments attempted and failed, including topical agents and cryosurgery. The specific treatment modality used must be documented. For treatments requiring prior failure of first-line options, the record must clearly show those failures.
• For laser treatment claims. The record must document the specific condition being treated, such as plaque psoriasis. It must include the body surface area affected. Previous treatments attempted and failed must be listed, including topical therapies and their duration. The Psoriasis Area and Severity Index score or other objective response measurement must be documented. The number of treatments planned and the response to initial treatments must be noted.
• For medication prior authorization. The record must document the specific diagnosis with an ICD-10 code. It must list all previous medications tried, including their names, doses, durations, and responses. For step-therapy requirements, the record must clearly show the failure of preferred alternatives. Contraindications or intolerances to the required step-therapy medications must be documented. Disease severity measures must be included. Relevant lab results, including tuberculosis screening for biologics, must be attached.
• For telehealth dermatology claims. The record must document that the service was provided via real-time audio and video technology. The patient’s location must be noted. The same clinical documentation standards apply as for in-person visits. Verbal consent for telehealth should be documented.
