ICD 10 Superbill Family Practice

Superbills in medical billing is a form used by healthcare providers. This form contains all the patient’s information, from diagnosis to the procedures/services performed. These superbills are the primary source of information for claim preparation. Later the medical claims are submitted to the insurance payers. Superbills also play a significant role in reimbursements of the healthcare physician as incorrect information leads to claim denials.


What information does the superbill ICD 10 contain?

After implementing the ICD-10 coding system, physicians were required to use ICD-10 superbills. These forms must contain the following information to receive reimbursements:

1. Provider’s information

Healthcare provider’s information includes the following:

Physician’s or provider’s NPI (National Provider Identifier) number

Name of the physician

If applicable, the referring provider’s name

If applicable, the referring provider’s NPI number

– Provider’s address & contact info

2. Patient’s information

This includes all the basic information of the patient, including:

Patient’s name

Date of birth (DOB)


Phone number/contact details

Patient’s insurance information

  • Social security number
  • Kind of insurance policy
  • Patient’s policy number
  • Deductibles/co-payment

3. Details about the patient’s visit to the physician

This part includes:

Correct and specific ICD-10-CM diagnosis codes:

In order to receive reimbursements from the insurance payer for the services or procedures performed, ICD 10 CM diagnosis codes must be included. The payer might not approve/accept the claim otherwise.


There are several commonly used modifiers in medical billing. These modifiers provide additional information to the insurance payer regarding the codes provided in the insurance claim. Note that a modifier doesn’t change the meaning of the medical code (e.g., ICD 10, CPT, HCPCS, etc.). Commonly used modifiers include:

  •   Modifier 22
  •   Modifier 25
  •   Modifier 59
  •   Modifier 91

Accurate CPT codes (procedure codes):

Current Procedural Terminology (CPT) codes are used to describe the procedures performed by the healthcare physician. Correct procedure codes are also crucial for proper reimbursements and revenue generation, along with diagnosis codes. The use of incorrect or outdated CPT codes can result in claims being denied or rejected by the insurance payers.

Other details included in the superbill:

The date of service/appointment/visit

Referring physician

Total amount charged for the service/visit

Minutes or units

Place of service (POS) code

Physician’s Signature

ICD 10 Superbill: Family Practice

In family practice, ICD 10 superbills can be any of the three types. Superbills examples/types may include:

For small healthcare practices, the superbills comprise the list of most commonly used diagnosis codes.

For a little larger healthcare practice, the staff extracts billable information from the patient’s medical records. This information is then translated into specific and valid codes to be incorporated into the superbills and then in the medical claim.

For healthcare practices using EHR systems, the software automatically converts the billable information.

In order to submit clean claims, correct and accurate medical codes must be used. In case of incorrect codes, the insurance payer can reject or deny the claim leading to lower reimbursements and revenues. For instance, when it comes to ICD 10 diagnosis codes assigning the code with correct laterality (and many more factors) is essential.

 Superbill vs. Claim:

Superbills are the healthcare providers’ main information source for preparing an insurance claim. It contains all the necessary information regarding the service(s) rendered and its charges. 

What is a super bill for insurance and its role in medical billing?

Superbill contains all the essential information of the patient and provider as well as details about the visit/service performed. These superbills are the primary source of information for healthcare providers in making a claim. They play a vital role in the following:

1. Reimbursements/revenues of the practice:

Superbill is an essential part of generating an insurance claim. It provides the healthcare provider/billing team with all the necessary information regarding the medical visit/services provided to the patient. Complete and accurate information is required in the claim so that the insurance payer doesn’t reject/deny it. Claim denials or rejections result in late/lost payments, lower reimbursements, therefore, lesser revenues.

2. Patient’s medical history or track record keeping:

As mentioned earlier, a superbill contains all the necessary patient medical and personal information. Therefore, it can also function as a document for maintaining a proper track of the patient’s medical data and information.

Why are Superbills necessary?

If superbills are offered by you, it may consume time to create a template. Following are some of the advantages of superbills, including proper record keeping, higher reimbursements, etc. 

Benefits of electronic superbills:

Manually entering diagnosis or procedure codes and other information can be quite frustrating, time-consuming, and dull. Moreover, entering manually also increases the risk of human error, meaning incorrect codes/info leading to claim denials or rejections. 

However, using the EHR system can simply resolve this issue. Electronic Health Records (EHR) software is used by various healthcare physicians/staff. But what if your practice doesn’t have an EHR?

Don’t worry; you can implement electronic superbills into your practice. Following are some of the benefits of electronic superbills in a non-EHR environment:

Quick selection of the ICD-10 codes

An improved Revenue Cycle Management (RCM) process

Saves valuable time of the healthcare physicians

Reduced paperwork

– The lesser risk of human errors

Faster payments

Electronic superbills are pretty beneficial for the healthcare practice compared to paperwork.

Superbill vs. CMS-1500:

Superbills contain all the information regarding services rendered along with their charges. CMS-1500 forms are used when the practice is an in-network provider with the insurance provider. However, superbills are used if the practice is out of the network with an insurance provider. Superbills allow them to receive payments for the services rendered upfront.

Family practice medical billing:

Unlike primary care physicians who specialize in one field, family practice physicians provide healthcare services in various fields of medicine. And that makes family practice one of the most complex and challenging medical billing and coding fields. The list of some top ICD 10 codes for family practice is mentioned above. This is why family practice medical coders must have a vast knowledge of CPT, ICD 10, & HCPCS codes for appropriate reimbursements.

Like every other kind of medical field, the family practice also relies on proper billing and coding. Due to high complexity, healthcare practices tend to outsource their billing services to third-party billing companies. With outsourced billing services, your practice can rely on:
