Medical Billing for Concierge Practices: A Complete Guide

Concierge medicine billing combines a membership or retainer model with a physician’s medical services, but the billing workflow can be considerably more complicated than a simple recurring membership payment. A concierge practice may collect a membership fee while separately submitting covered clinical services to commercial insurance or Medicare, depending on the practice model, payer contracts, and the physician’s enrollment or opt-out status.

That creates several billing and coding points that deserve careful attention. A claim can be denied because the diagnosis does not support medical necessity, a service can be incorrectly included in a membership fee, or a practice can create compliance risk by treating a retainer agreement as if it were a universal substitute for insurance billing. Poor documentation can also lead to undercoding, overcoding, delayed reimbursement, incorrect patient balances, and audit exposure.

This guide explains how concierge practices can structure their medical billing workflows, select appropriate CPT and HCPCS codes, assign ICD-10-CM diagnosis codes, document medical necessity, handle membership and insurance charges, and reduce common claim errors. It also covers Medicare considerations, preventive services, evaluation and management coding, chronic care management, diagnosis coding, documentation, claim scrubbing, and practical coding examples.

What Is Concierge Medicine Billing?

Concierge medicine billing is the process of managing both the membership or retainer revenue of a concierge practice and the separately billable medical services that may be submitted to a patient’s health plan.

The key distinction is that concierge medicine billing is a practice model, not a CPT or ICD-10-CM diagnosis category. There is no universal “concierge medicine CPT code” and no ICD-10-CM diagnosis code that should be assigned simply because a patient belongs to a concierge practice.

Instead, coding follows the actual service and the documented reason for the encounter.

For example, a concierge physician might provide:

• A problem-oriented office E/M visit
• A preventive examination
• A Medicare Annual Wellness Visit
• Chronic disease management
• Transitional care management
• Advance care planning
• Vaccination and administration
• Diagnostic testing
• Remote patient monitoring or other covered services, when applicable
• Care coordination services that independently meet applicable billing requirements

The membership fee is handled separately according to the practice’s contract and applicable payer and legal requirements.

This distinction is fundamental. A practice should not select a diagnosis or procedure code simply because a patient pays a concierge membership fee.

2026 Coding and Billing Rules for Concierge Practices

For services furnished in 2026, practices need to use the code set and payer rules applicable to the date of service.

The 2026 CPT code set became effective January 1, 2026. The AMA states that the 2026 CPT Standard Data File contains more than 11,500 codes and includes the annual revisions to the CPT code set.

For ICD-10-CM, FY 2026 applies from October 1, 2025 through September 30, 2026. CDC/NCHS also issued an April 1, 2026 update, with FY 2026 codes applicable to services from April 1 through September 30, 2026 where that release changed the applicable code set.

Therefore, a billing team should always confirm:

1. Date of service
2. Applicable CPT edition
3. Applicable ICD-10-CM release
4. Payer-specific coding policy
5. Patient’s insurance coverage
6. Provider participation status
7. Medical necessity requirements
8. Any applicable modifiers
9. Whether the service is included in another billed service
10. Whether the membership agreement affects the patient’s financial responsibility

Medicare payment rules are also updated annually. CMS maintains the 2026 Physician Fee Schedule and related payment files, so a practice should not rely on an older fee schedule when determining Medicare payment information.

Common CPT, HCPCS & ICD-10-CM Codes Used in Concierge Primary Care

There is no single master list of “concierge medicine codes.” Code selection depends on what the physician actually performs and documents.

The following table covers common code families that may arise in concierge primary care and related longitudinal-care workflows.

CMS confirms that Medicare AWVs use G0438 and G0439, not CPT 99381–99397. CMS also states that an AWV claim requires a diagnosis code consistent with the patient’s examination, but does not mandate one specific AWV diagnosis code.

A critical distinction about the diagnosis codes

The ICD-10-CM codes above are examples of diagnoses and encounter reasons commonly encountered in longitudinal primary care. They are not “concierge diagnosis codes.”

For instance:

• Z00.00 = general adult medical examination without abnormal findings
• Z00.01 = general adult medical examination with abnormal findings
• Z23 = encounter for immunization
• I10 = essential hypertension
• E11.9 = type 2 diabetes mellitus without complications

A coder must assign the diagnosis supported by the provider’s documentation for that encounter. The concierge membership itself does not justify an additional medical diagnosis code.

1. Start with the actual service provided

The first question is not, “Is this a concierge patient?”

Ask:

What service did the provider actually perform?

Was it:

• A problem-oriented E/M visit?
• A preventive service?
• An AWV?
• Chronic care management?
• Transitional care management?
• Advance care planning?
• A home/residence visit?
• A diagnostic service?
• A vaccine administration?
• Another separately identifiable service?

The CPT or HCPCS code must describe the service actually performed.

2. Determine whether the service is part of the membership arrangement

The practice’s membership agreement should clearly identify what the patient receives for the retainer or membership fee.

A billing team should understand whether the membership includes:

• Enhanced access
• Extended appointments
• Care coordination
• Administrative services
• Certain noncovered services
• Communication access
• Preventive services
• Clinical visits
• Other defined services

The agreement should not be treated as permission to automatically bill an insurer for every service.

The AMA describes retainer arrangements as arrangements in which patients pay additional fees for services or amenities distinct from the cost of medical care, while emphasizing the need for clear terms and transparency.

3. Verify the payer and provider relationship

Before submitting a claim, determine whether the physician is:

• Participating
• Nonparticipating
• Out of network
• Contracted with a commercial payer
• Opted out of Medicare
• Subject to a Medicare Advantage arrangement
• Otherwise subject to payer-specific contractual requirements

Medicare participation matters because participating providers agree to accept assignment on Medicare-covered services and accept the applicable Medicare allowed amount as payment in full, subject to applicable patient cost-sharing.

4. Select the appropriate CPT or HCPCS code

For office/outpatient E/M services, the current CPT framework allows selection based on medical decision making or total time, depending on the applicable code and circumstances. The AMA’s current E/M guidance confirms that the office/outpatient E/M revisions remain foundational to current coding.

Do not select a higher E/M code merely because a concierge visit is longer or more personalized.

The documentation must support the reported service.

5. Assign the diagnosis from provider documentation

The diagnosis should explain the reason for the service and, where applicable, support medical necessity.

For example, if a patient is seen for management of documented hypertension and diabetes, the claim should reflect the diagnoses actually addressed and documented.

A coder should not infer a diagnosis from a laboratory value alone when provider documentation does not establish the diagnosis.

6. Check medical necessity

A correctly formatted claim can still be denied.

Review:

• Diagnosis-to-service relationship
• Payer medical policy
• Frequency limitations
• Coverage requirements
• Patient eligibility
• Prior authorization requirements
• Modifier requirements
• Documentation requirements

CMS describes the Physician Fee Schedule as the primary Medicare payment method for many professional services and maintains payment policies and lookup resources for applicable services.

7. Apply payer-specific rules before submission

Commercial payers may have different rules from Medicare.

The billing team should maintain a payer matrix covering:

• Covered services
• Noncovered services
• Preventive benefits
• E/M policies
• Telehealth policies
• Modifier rules
• Authorization
• Diagnosis requirements
• Timely filing
• Member cost sharing
• Medical policies

Documentation Checklist for Concierge Medicine Billing

Documentation is the bridge between the clinical encounter and the claim.

A concierge practice should ensure that the record clearly establishes what happened during the encounter and why the service was medically necessary.

Weak documentation

“Annual physical. Patient doing well.”

This may not adequately establish what service was actually performed, what conditions were addressed, or whether additional medically necessary services were provided.

Better documentation

“Established patient presents for preventive examination. Hypertension and type 2 diabetes reviewed. Blood pressure controlled on current regimen. Diabetes management reviewed; medication adherence and follow-up laboratory monitoring discussed. Preventive counseling and age-appropriate screening reviewed.”

This gives the coder more information about the encounter.

Stronger documentation

“Patient presents for preventive examination. In addition to preventive services, physician evaluated and managed established hypertension and type 2 diabetes. Medication effectiveness and adherence were reviewed, current treatment continued, and follow-up laboratory testing ordered based on the documented conditions. Assessment and plan separately address each condition.”

The exact codes still depend on the complete record and payer requirements, but the documentation makes the distinction between preventive and problem-oriented care clearer.

High-Risk Billing and Coding Rules in Concierge Practices

Membership fees are not automatically medical claims

A recurring membership charge does not become a CPT-coded medical service simply because the physician provides healthcare within the membership relationship.

The practice should maintain a clear accounting distinction between:

1. Membership or retainer revenue
2. Insurance-billed clinical services
3. Patient cost sharing
4. Noncovered services
5. Administrative or convenience services

The exact treatment of these charges should be reviewed against the practice agreement, payer contracts, applicable law, and professional advice.

Medicare patients require special attention

Medicare is one of the highest-risk areas for concierge billing.

A physician who has opted out of Medicare cannot simply bill Medicare for covered services. CMS states that an opted-out practitioner must generally enter into a private contract with each Medicare patient, and neither the physician nor beneficiary submits those privately contracted services to Medicare for payment. Opt-out status also has a two-year period and specific renewal requirements.

That is fundamentally different from a practice that participates in Medicare while charging a separate fee for permissible non-covered services or amenities.

Because the legal and financial consequences can be significant, practices should have their particular concierge arrangement reviewed before implementation.

Medicare AWV vs. comprehensive preventive examination

This is a frequent source of errors.

For Medicare beneficiaries, G0438 and G0439 are the AWV codes. CMS specifically instructs providers not to bill CPT 99381–99397 for the Medicare IPPE or AWV benefit.

The distinction matters because a concierge practice may routinely use comprehensive preventive medicine CPT codes with commercial payers, while Medicare uses its own benefit structure.

G2211 requires careful review

G2211 is particularly relevant to concierge practices because it addresses the complexity associated with ongoing longitudinal care.

CMS explains that the code is intended to capture complexity arising from the practitioner’s ongoing responsibility for a patient’s care rather than simply the severity of an isolated condition.

For 2026, CMS also allows G2211 with specified home/residence E/M codes beginning January 1, 2026.

Do not append G2211 simply because a physician has a long-term relationship with the patient. The underlying E/M service must be medically reasonable and necessary and meet CMS requirements.

Preventive service plus problem-oriented E/M

A concierge physician may perform preventive services and separately evaluate an active medical problem during the same encounter.

Medicare allows an additional medically necessary E/M service when it is significant and separately identifiable from the AWV, with modifier 25 used as applicable. CMS provides specific rules for this circumstance.

The documentation should make the additional work apparent rather than relying on the membership relationship to justify a separate charge.

Concierge Medicine Coding Examples

Can a Concierge Practice Code a Diagnosis From Lab Results Alone?

Generally, coders should not independently establish a definitive diagnosis from a laboratory result, imaging study, or other clinical indicator when the provider has not documented the diagnosis and the applicable coding rules do not authorize such inference.

For example, an elevated glucose value does not automatically permit a coder to assign diabetes.

Similarly:

• An elevated TSH does not automatically establish hypothyroidism.
• An elevated LDL does not automatically establish a specific lipid disorder.
• An abnormal liver enzyme does not automatically establish a liver disease.
• An imaging finding does not automatically establish the final clinical diagnosis unless the applicable coding rules support assignment.

The provider’s clinical assessment and documentation remain central.

When the clinical record contains conflicting, incomplete, or ambiguous information, a compliant provider query may be appropriate. The query should seek clarification rather than lead the provider toward a particular diagnosis.

Outpatient vs. Inpatient Coding in Concierge Medicine

Most concierge billing occurs in outpatient settings, so the outpatient uncertain-diagnosis rule is particularly important.

Outpatient encounters

For outpatient coding, diagnoses documented as:

• Probable
• Suspected
• Possible
• Rule out
• Questionable
• Working diagnosis

are generally not coded as confirmed conditions merely because the provider is considering them.

Instead, code the confirmed condition, signs, symptoms, abnormal findings, or reason for the encounter as supported by the applicable outpatient coding rules.

Inpatient admissions

The rules for inpatient hospital discharge coding are different.

Under the inpatient uncertain-diagnosis rules, certain diagnoses documented at discharge as probable, suspected, likely, questionable, or similar may be coded as if they existed when the applicable guideline requirements are met.

Do not transfer this inpatient rule to an outpatient concierge office claim.

Common Concierge Medicine Billing Mistakes

Using the membership model as the diagnosis

A concierge membership is not a medical diagnosis.

Correct approach: Code the documented reason for the encounter and the conditions addressed.

Billing every service as part of the membership

Not every service should automatically be bundled into the retainer, and not every service should automatically be submitted to insurance.

Correct approach: Define the membership contract, identify covered/noncovered services, and follow payer and legal requirements.

Choosing an E/M level because the physician spent a long time with the patient

Longer visits can be appropriate, but time alone does not justify a particular code unless the code’s time-based methodology and documentation requirements are satisfied.

Correct approach: Select the E/M level using the current CPT framework and document the applicable MDM or qualifying time.

Using 99381–99397 for a Medicare AWV

CMS specifically states that Medicare AWVs should be reported with G0438 or G0439, not CPT 99381–99397.

Reporting G2211 automatically

Longitudinal concierge relationships may make G2211 relevant, but the code is not an automatic payment for being a concierge physician.

Correct approach: Apply CMS’s specific G2211 requirements and document the underlying E/M service.

Coding chronic diseases that were not addressed

A diagnosis appearing in an old problem list does not necessarily mean it should be reported on every claim.

Correct approach: Follow the applicable reporting guidelines and document conditions that are relevant to the encounter.

Using an unspecified diagnosis when specificity is documented

For example, if the provider documents a specific type or complication of a disease, do not default to an unspecified code.

Correct approach: Review the complete documentation and select the most specific supported code.

Assuming a laboratory abnormality is a diagnosis

A coder should not convert every abnormal result into a disease code.

Correct approach: Use provider documentation and applicable coding rules; query when clarification is necessary.

Best Practices for Clean Concierge Medicine Claims

Separate membership accounting from insurance billing

Create distinct workflows for:

• Membership enrollment
• Recurring payments
• Membership cancellations
• Insurance claims
• Patient balances
• Denials
• Refunds
• Noncovered services

This makes it easier to reconcile revenue and explain patient financial responsibility.

Build diagnosis-specific EHR prompts

Templates should encourage providers to document:

• Reason for encounter
• Conditions addressed
• Current status
• Treatment decisions
• Medication changes
• Diagnostic work
• Follow-up plan
• Preventive services
• Medical necessity

Templates should assist documentation without forcing diagnoses that are not clinically appropriate.

Create targeted claim edits

Useful edits can flag:

• Missing diagnosis
• Invalid ICD-10-CM code
• Code not valid for date of service
• AWV frequency conflicts
• Missing modifier
• Missing authorization
• Diagnosis/procedure mismatch
• Medicare participation conflict
• Potential duplicate billing
• Missing required time documentation
• Incomplete TCM or CCM documentation

Audit unspecified-code usage

A high percentage of unspecified diagnoses can be a signal that providers are not documenting enough detail.

The goal should not be to eliminate every unspecified code. An unspecified code can be correct when the documentation genuinely does not establish greater specificity.

Query instead of assuming

A compliant query is preferable to guessing.

If documentation says:

“Abnormal kidney function”

but the provider’s assessment does not clarify the condition, the coder should not independently convert that phrase into a specific chronic kidney disease stage.

Monitor payer policies

A concierge practice may have multiple payer relationships, and commercial payer policies can differ from Medicare.

Maintain current references for:

• Medical necessity
• Preventive benefits
• E/M services
• Telehealth
• Care management
• Vaccines
• Diagnostic testing
• Prior authorization
• Frequency limitations

Frequently Asked Questions

What is the CPT code for concierge medicine?

There is no single CPT code for concierge medicine. Concierge medicine is a practice and payment model. The CPT or HCPCS code depends on the service actually performed, such as an office/outpatient E/M visit, AWV, care-management service, preventive service, or another covered service.

Is there an ICD-10 code for concierge medicine?

There is no universal ICD-10-CM diagnosis code for concierge medicine. Coders should report the documented reason for the encounter and applicable diagnoses rather than assigning a code simply because the patient belongs to a concierge practice.

Can concierge doctors bill insurance?

Some concierge practices can bill insurance for covered medical services, while others use different payment arrangements. The answer depends on the practice’s model, payer contracts, provider participation status, and applicable law. Concierge medicine and direct primary care are not necessarily identical models; the AMA notes that concierge practices often combine membership fees with insurance billing, while DPC practices commonly do not bill insurers.

Can a concierge practice bill Medicare?

It depends on the physician’s Medicare status and the service being provided. Participating and nonparticipating providers follow Medicare claim rules, while physicians who properly opt out generally use private contracts with Medicare beneficiaries for covered services rather than submitting those services to Medicare.

What diagnosis code should be used for a concierge annual physical?

The diagnosis depends on the actual service and documentation. For a general adult examination, Z00.00 or Z00.01 may be applicable depending on whether abnormal findings are documented. For a Medicare AWV, CMS does not require one specific AWV diagnosis code; the diagnosis should be consistent with the examination.

Can a concierge practice use 99214 for a long patient visit?

99214 may be appropriate when the documented service meets the applicable CPT requirements. The fact that a practice is concierge or that the patient pays a membership fee does not independently justify 99214. E/M selection must follow the current CPT methodology using MDM or qualifying time, as applicable.

Can G2211 be used by concierge physicians?

Potentially, but only when the Medicare requirements are met. G2211 is intended for qualifying longitudinal office/outpatient E/M complexity and is not simply a concierge membership add-on. CMS provides specific rules concerning the underlying E/M service, modifier 25, preventive services, and other circumstances.

Can a coder assign diabetes from an elevated glucose result?

Not simply from the laboratory result. Unless applicable coding rules specifically allow assignment, the coder should rely on provider documentation rather than independently establishing a diagnosis from laboratory data. A compliant query may be appropriate when clarification is needed.

What are the most common diagnosis codes in concierge primary care?

Common codes depend on the patients and services treated. Examples include Z00.00/Z00.01 for general adult examinations, Z23 for immunization encounters, I10 for essential hypertension, E11.9 for type 2 diabetes without complications, E78.- for hyperlipidemia, and other condition-specific codes. The correct code must always reflect the provider’s documentation.

Does a correct CPT and ICD-10-CM combination guarantee payment?

No. Correct coding does not guarantee reimbursement. Payment can also depend on eligibility, benefits, medical necessity, authorization, payer policy, participation status, frequency limits, timely filing, modifiers, documentation, and contractual requirements.

When should a concierge practice query the provider?

A provider query is appropriate when the documentation is incomplete, conflicting, ambiguous, or insufficient to accurately report a diagnosis or service. The query should clarify the record without directing the provider toward an unsupported diagnosis.

Conclusion

Successful concierge medicine billing requires more than collecting a recurring membership fee and submitting occasional insurance claims. The practice needs a clear separation between membership revenue and billable medical services, accurate CPT/HCPCS selection, diagnosis coding based on provider documentation, and a reliable process for verifying medical necessity and payer requirements.

For coding teams, the most important principle is to avoid treating concierge status as a diagnosis or procedure. The correct claim reflects the service performed, the patient’s documented condition or reason for the encounter, the applicable payer rules, and the date-of-service code set. Preventive services, E/M visits, chronic care management, transitional care management, AWVs, and longitudinal-care services each have their own requirements.

A well-designed concierge billing workflow should also address Medicare participation or opt-out status, membership agreements, documentation, claim edits, payer policies, and audit controls. These safeguards help reduce denials, incorrect reimbursement, coding assumptions, documentation gaps, and compliance risk while giving the practice a cleaner and more defensible revenue cycle.
