The hardest billing problem in concierge medicine is not the membership fee. It is the boundary between the membership fee and the insurance claim.
Most concierge practices charge a membership fee for enhanced access, availability, and communication. They also bill insurance for covered medical services. The membership covers one thing. The insurance claim covers another. If the practice cannot clearly separate those two revenue streams in its workflow, the result is compliance risk, patient confusion, and billing errors that are hard to detect until they become a real problem.
This article covers how the boundary works, where it breaks down, and what the billing workflow needs to handle. It is a billing operations guide, not legal or compliance advice. Practices should confirm regulatory details with counsel.
What the membership fee covers versus what insurance covers
In a typical concierge model, the membership fee covers access and availability: smaller panels, longer visits, same-day or next-day appointments, direct communication with the physician, and enhanced care coordination. The AMA Code of Medical Ethics addresses retainer practices and notes that physicians who enter retainer contracts should uphold ethical obligations around access, quality, and continuity.
Insurance covers the clinical service: the exam, the procedure, the lab order, the diagnostic code, and the CPT code that corresponds to what was done during the encounter.
The membership fee should not be billed to insurance. It is not a covered medical service. It is a direct arrangement between the patient and the practice for access-level benefits that insurance does not reimburse.
The insurance claim should not include charges for services that the membership already covers if those services are defined as part of the membership agreement and are not separately billable under the patient’s plan.
That separation sounds simple. In practice, it is where most hybrid billing mistakes happen.
Where the boundary breaks down
The membership agreement is vague about what is included
If the membership agreement says the fee covers “comprehensive care” or “all primary care services” without defining what that means at the billing level, every encounter becomes ambiguous. Is this visit covered by the membership? Should it also be billed to insurance? Can it be both?
The agreement should list which services are included in the membership and which are not, in enough detail that the billing team can make the right call at the point of service.
Insurance is billed for services the membership already covers
If the membership includes annual wellness visits and the practice also bills insurance for the same visit, that is a double-billing problem. The practice is collecting twice for the same service: once from the patient through the membership fee and once from the insurer through the claim.
This is a compliance risk. It is also a payer audit risk if the insurer identifies that the practice is billing for services the patient has already paid for through a separate arrangement.
Insurance is not billed for services it should cover
The reverse problem. A concierge practice may default to treating everything as membership-covered and stop billing insurance for services that the patient’s plan would cover. The practice collects the membership fee but leaves insurance revenue on the table. The patient loses credit toward their deductible.
Medicare patients and the membership fee
For Medicare patients, the boundary is stricter. CMS has stated that a physician who has not opted out of Medicare cannot charge a Medicare beneficiary for a Medicare-covered service outside of the Medicare payment system, except in specific circumstances. A concierge practice that charges Medicare patients a membership fee must ensure the fee covers only non-covered services or access-level benefits, not Medicare-covered clinical services.
If the membership fee effectively charges for Medicare-covered services, the practice may be in violation of Medicare billing rules. This is an area where legal and billing review should align before the practice enrolls Medicare patients in a membership program.
What the EHR and billing workflow need to handle
The billing system needs to make the membership-insurance boundary operational, not just conceptual.
Per-encounter billing pathway. The EHR should be able to flag each encounter as membership-covered, insurance-billed, or patient-pay. If the system defaults everything to one pathway, the wrong claims will be generated.
Membership status on the patient record. The billing team needs to know whether the patient is a member and what the membership includes before generating a claim. If membership status is tracked outside the EHR (in a spreadsheet or separate system), the disconnection will cause errors.
Claim suppression for membership-covered services. If a service is defined as included in the membership, the EHR should not generate an insurance claim for it. If claim generation is automatic, suppression rules need to be configured deliberately.
Separate revenue reporting. Membership revenue and insurance revenue should be trackable separately. If the practice cannot report how much revenue comes from memberships versus insurance versus patient-pay, it cannot verify that the boundary is being enforced.
Common mistakes in hybrid billing
- Billing insurance for a service the membership agreement says is included.
- Not billing insurance for a service the membership does not cover, leaving revenue uncollected.
- Charging Medicare patients a membership fee that includes Medicare-covered services.
- Using one billing pathway for all patients regardless of membership status.
- Not updating the membership agreement when the practice changes what is included.
- Failing to train the front desk, billing team, and clinical staff on which services fall on which side of the boundary.
What to check
- Does the membership agreement clearly define which services are included and which are not?
- Does the EHR flag each encounter by billing pathway (membership, insurance, patient-pay)?
- Are claims being suppressed for membership-covered services?
- Are insurance claims being submitted for services outside the membership?
- Are Medicare patients being charged membership fees only for non-covered services?
- Can the practice report membership revenue and insurance revenue separately?
- Does the front desk know the billing pathway for each encounter before it happens?
If the answers are unclear, the boundary is not being enforced in the workflow. It exists on paper but not in practice. For related guidance on DPC and insurance, see Can DPC Practices Still Bill Insurance for Labs and Imaging?.
How Neobill can help
Neobill works with concierge, DPC, and hybrid practices where the billing model involves multiple revenue streams. The free audit reviews the boundary between membership-covered and insurance-billed services, identifies where the workflow creates compliance risk or leaves revenue uncollected, and helps the practice build a billing process that matches its actual model.
