Two tiers, one calendar: designing a hybrid retainer practice
Summary
A hybrid retainer practice, in which some patients pay a membership fee while everyone else stays on ordinary insurance billing, is a recognized design with specific limits. Ethics guidance confines the fee to non-medical amenities, billed separately from insurance-reimbursed care, with the same quality of medical care owed to every patient. Medicare is where the design usually breaks: a covered service still requires a claim, and the only lawful route to bill a Medicare patient directly for a covered service opts the physician out of Medicare entirely.

Can one practice run a retainer tier and an insurance panel?
Yes. A physician can charge some patients a membership fee for enhanced access and amenities while continuing to see everyone else through ordinary insurance billing. GAO described that pattern in its 2005 report on concierge care, which defines the model as a membership fee charged in return for enhanced services or amenities and notes that some concierge physicians keep seeing patients through traditional insurance arrangements 1Ref 1U.S. Government Accountability Office (GAO) (2005).Physician Services: Concierge Care Characteristics and Considerations for Medicare.The definition of concierge care as a membership fee charged in return for enhanced services or amenities, the finding that some concierge physicians continue to see patients through traditional insurance arrangements, and the framed 2004 survey benchmark of 112 self-identified concierge physicians reporting an average of 326 concierge patients against 2,716 patients before the change, carried with GAO's own caution that the respondents were not randomly selected and cannot be projected to other physicians..
A hybrid retainer practice is that arrangement run deliberately: two contractual tiers, one panel, one schedule. The tiers are permitted. What is constrained is what the retainer fee may buy, what stays on the insurance claim, and what the patients who decline are still owed.
The American Medical Association's Council on Ethical and Judicial Affairs addresses the arrangement in Opinion 11.2.5 of the Code of Medical Ethics 2Ref 2American Medical Association, Council on Ethical and Judicial Affairs (2026).Opinion 11.2.5 Retainer Practices.The ethical envelope of a two-tier practice: charges for retainer amenities must be clearly distinguished from insurance-reimbursable medical services, the physician must not imply that more or better medical care comes with the contract, every patient is owed the same quality of medical care regardless of contractual arrangement, and a patient who declines is owed continued care under existing insurance terms plus help transferring.. That is ethics guidance rather than law, and it prints no adoption date, so cite it as the current version. It is also the most specific published statement of where the line runs inside a mixed practice.
What the retainer fee may buy, and what stays on the claim
Amenities and non-medical services, priced and billed on their own. Opinion 11.2.5 tells physicians to clearly distinguish charges for special services or amenities provided under a retainer contract from medical services reimbursable by the patient's health care insurance 2Ref 2American Medical Association, Council on Ethical and Judicial Affairs (2026).Opinion 11.2.5 Retainer Practices.The ethical envelope of a two-tier practice: charges for retainer amenities must be clearly distinguished from insurance-reimbursable medical services, the physician must not imply that more or better medical care comes with the contract, every patient is owed the same quality of medical care regardless of contractual arrangement, and a patient who declines is owed continued care under existing insurance terms plus help transferring.. The medical care keeps running through the claim it always ran through, and the fee sits beside it on its own invoice.
The second constraint governs what the tier may say about itself. The same opinion tells physicians to take care not to imply that more or better medical services will be provided under a retainer contract 2Ref 2American Medical Association, Council on Ethical and Judicial Affairs (2026).Opinion 11.2.5 Retainer Practices.The ethical envelope of a two-tier practice: charges for retainer amenities must be clearly distinguished from insurance-reimbursable medical services, the physician must not imply that more or better medical care comes with the contract, every patient is owed the same quality of medical care regardless of contractual arrangement, and a patient who declines is owed continued care under existing insurance terms plus help transferring.. Enrollment materials that hint at better medicine are the part a complaint would quote back.
A benefit list that survives both rules runs to scheduling and communication: longer scheduled visits, same-day or next-day access, direct messaging, coordination work that no code pays for. Those are conventions rather than a published standard. But the test each item passes is written down. If a plan would reimburse it, it belongs on the claim rather than in the membership.
What the patients who decline are still owed
The same quality of medical care as everyone else, care continuing under their existing insurance terms, and help transferring if they would rather leave. Opinion 11.2.5 states all three: the same quality of medical care regardless of contractual arrangements, care under the terms of the patient's existing health care insurance until other appropriate arrangements can be made, and facilitated transfer for any patient who chooses not to participate 2Ref 2American Medical Association, Council on Ethical and Judicial Affairs (2026).Opinion 11.2.5 Retainer Practices.The ethical envelope of a two-tier practice: charges for retainer amenities must be clearly distinguished from insurance-reimbursable medical services, the physician must not imply that more or better medical care comes with the contract, every patient is owed the same quality of medical care regardless of contractual arrangement, and a patient who declines is owed continued care under existing insurance terms plus help transferring..
That third duty is where hybrid designs get complacent, because a hybrid is supposed to be the version where nobody has to leave. The ethics rule speaks to quality of medical care rather than convenience, so a longer wait for a non-member appointment does not breach it on its face.
The federal constraints are separate from the ethical ones, and they land on one group of patients.
Medicare beneficiaries decide the shape
Medicare is where most hybrid designs get redrawn. For every covered service furnished to a Medicare beneficiary, the mandatory claim submission duty at Social Security Act section 1848(g)(4) requires a claim, whatever private fee arrangement runs alongside it, and a violation can draw a civil monetary penalty of up to $2,000 for each violation plus possible program exclusion 3Ref 3Noridian Healthcare Solutions (CMS Medicare Administrative Contractor, Jurisdiction E Part B) (2025).Mandatory Claim Submission - JE Part B.The Social Security Act section 1848(g)(4) duty to submit a claim for every covered service furnished to a Medicare beneficiary regardless of any private fee arrangement, the civil monetary penalty of up to $2,000 per violation with possible program exclusion, and the bar on charging a patient to prepare or file the claim..
So the fee cannot stand in for the claim, and the practice cannot charge the patient to prepare or file it 3Ref 3Noridian Healthcare Solutions (CMS Medicare Administrative Contractor, Jurisdiction E Part B) (2025).Mandatory Claim Submission - JE Part B.The Social Security Act section 1848(g)(4) duty to submit a claim for every covered service furnished to a Medicare beneficiary regardless of any private fee arrangement, the civil monetary penalty of up to $2,000 per violation with possible program exclusion, and the bar on charging a patient to prepare or file the claim..
Charging a Medicare patient directly for a service Medicare would otherwise cover has one lawful route: a private contract under 42 CFR Part 405, Subpart D. One such contract with one beneficiary opts the physician out of Medicare for the whole two-year opt-out period, and services under it draw no Medicare payment at all, directly or indirectly 4Ref 4Centers for Medicare & Medicaid Services (CMS), Department of Health and Human Services (2024).Code of Federal Regulations, Title 42, Chapter IV, Subchapter B, Part 405, Subpart D — Private Contracts (§405.400 Definitions, §405.405 General rules, §405.410 Conditions for properly opting-out, §405.415 Requirements of the private contract).The private-contract mechanics that decide a hybrid's Medicare posture: entering even one private contract with one beneficiary opts the physician out of Medicare for the whole two-year opt-out period, and services furnished under such a contract draw no Medicare payment directly or indirectly..
The contract also has to say so out loud: the beneficiary agrees not to submit a claim to Medicare, and not to ask the physician to submit one 5Ref 5Noridian Healthcare Solutions (CMS Medicare Administrative Contractor, Jurisdiction E Part B) (2026).Private Contracts with Medicare Beneficiaries - JE Part B.The requirement that a Medicare private contract carry the beneficiary's affirmative agreement not to submit a claim to Medicare, and not to ask the physician to submit one, for the contracted service.. No enrollment brochure accomplishes that by implication.
Opting out is a filing with dates attached: a signed affidavit with each Medicare Administrative Contractor the physician deals with, and for a physician already participating, an effective date only at the start of a calendar quarter, on 30 days' notice 6Ref 6Centers for Medicare & Medicaid Services (2023).42 CFR § 405.410 — Conditions for properly opting-out of Medicare.What opting out requires as a filing: a signed affidavit with each Medicare Administrative Contractor, and for a physician already participating, an effective date only at the start of a calendar quarter on 30 days' notice..

| Retainer tier offered to non-Medicare patients only | No Medicare claim or contract mechanics; Opinion 11.2.5's duties still run to every patient 2Ref 2American Medical Association, Council on Ethical and Judicial Affairs (2026).Opinion 11.2.5 Retainer Practices.The ethical envelope of a two-tier practice: charges for retainer amenities must be clearly distinguished from insurance-reimbursable medical services, the physician must not imply that more or better medical care comes with the contract, every patient is owed the same quality of medical care regardless of contractual arrangement, and a patient who declines is owed continued care under existing insurance terms plus help transferring. | A tier that includes the practice's oldest patients |
Most working hybrids sit in the first row. The second ends Medicare billing for the practice, not only for the members who signed.
The waiver problem in a mixed-payer practice
A member perk that is harmless in a cash-only practice can carry federal exposure once part of the panel is covered by Medicare or a state health care program. The Office of Inspector General's 2023 General Compliance Program Guidance restates the Beneficiary Inducements distinction: a waiver of a patient charge escapes scrutiny only when it is nonroutine and tied to an individual determination of financial need 7Ref 7U.S. Department of Health and Human Services, Office of Inspector General (2023).General Compliance Program Guidance.The Beneficiary Inducements distinction applied to member perks in a mixed-payer practice: a waiver of a patient charge escapes scrutiny only when it is nonroutine and tied to an individual determination of financial need, an exposure a purely cash-paying panel does not carry..
A retainer tier produces routine waivers by design: the no-show fee nobody enforces for members, the cost-sharing quietly absorbed, the complimentary visit that turns out to be a covered service. Each is granted because of membership rather than because of a financial-need finding about one person.
The exposure is confined to the federal-program part of the panel, which is what makes it easy to miss in a practice that thinks of itself as private-pay.
The trigger worth taking to health care counsel is short: any member benefit with a dollar value a federal-program patient would otherwise have paid for.
Sizing the two tiers and the calendar
No published benchmark says how much of a panel a hybrid tier can absorb before the insurance side stops paying for itself. The nearest public figure does not separate hybrids from full conversions: in GAO's 2004 survey of 112 self-identified concierge physicians, respondents averaged 326 concierge patients against 2,716 patients before the change, and GAO cautioned that the 112 were not randomly selected and cannot be projected to other physicians 1Ref 1U.S. Government Accountability Office (GAO) (2005).Physician Services: Concierge Care Characteristics and Considerations for Medicare.The definition of concierge care as a membership fee charged in return for enhanced services or amenities, the finding that some concierge physicians continue to see patients through traditional insurance arrangements, and the framed 2004 survey benchmark of 112 self-identified concierge physicians reporting an average of 326 concierge patients against 2,716 patients before the change, carried with GAO's own caution that the respondents were not randomly selected and cannot be projected to other physicians..
Read that as arithmetic rather than a target. It reports panel size, and nothing in it says how a hybrid splits its week. The constraint a hybrid carries is that the fee-for-service schedule still has to fill the week around the members, and every reserved member slot is one the insurance panel no longer has. No published ratio exists, and any number offered as one is convention.
The rest of that arithmetic is pricing the tiers, and it turns on the amenity list: whatever the member pays has to be defensible as payment for amenities alone.
Then the calendar. Whether to run two calendars or one is an operating choice with no rule behind it: member slots reserved inside a single calendar are visible to whoever books everyone else, while two calendars, one suite, hides the reservation and makes double-booking possible.
The membership agreement's own renewal date belongs on the expirables calendar beside the license and DEA registration dates. A term that lapses quietly is a fee collected with no current agreement behind it.
What to settle before the first enrollment letter
Settle these before anything reaches patients, because each decision constrains the next and two of them are expensive to reverse. The Medicare posture decides what the fee may cover, the fee's contents decide what the agreement says, and the agreement decides what the enrollment letter may promise. The letter is the document a complaint would quote.
1. Decide the Medicare posture first. Staying enrolled keeps the claim duty and confines the fee to amenities; the private-contract route ends Medicare billing for the whole practice 4Ref 4Centers for Medicare & Medicaid Services (CMS), Department of Health and Human Services (2024).Code of Federal Regulations, Title 42, Chapter IV, Subchapter B, Part 405, Subpart D — Private Contracts (§405.400 Definitions, §405.405 General rules, §405.410 Conditions for properly opting-out, §405.415 Requirements of the private contract).The private-contract mechanics that decide a hybrid's Medicare posture: entering even one private contract with one beneficiary opts the physician out of Medicare for the whole two-year opt-out period, and services furnished under such a contract draw no Medicare payment directly or indirectly.. 2. Write the amenity schedule as its own priced document, so the separation the ethics opinion requires is visible on paper rather than asserted 2Ref 2American Medical Association, Council on Ethical and Judicial Affairs (2026).Opinion 11.2.5 Retainer Practices.The ethical envelope of a two-tier practice: charges for retainer amenities must be clearly distinguished from insurance-reimbursable medical services, the physician must not imply that more or better medical care comes with the contract, every patient is owed the same quality of medical care regardless of contractual arrangement, and a patient who declines is owed continued care under existing insurance terms plus help transferring.. 3. Read each payer participation agreement. Whether a commercial plan tolerates a membership fee layered on its own reimbursement is a contract question no statute answers across payers. 4. Write down what the non-enrolled panel keeps, in the words you will use with them: the same standard of care, care under their current insurance, and a transfer if they want one 2Ref 2American Medical Association, Council on Ethical and Judicial Affairs (2026).Opinion 11.2.5 Retainer Practices.The ethical envelope of a two-tier practice: charges for retainer amenities must be clearly distinguished from insurance-reimbursable medical services, the physician must not imply that more or better medical care comes with the contract, every patient is owed the same quality of medical care regardless of contractual arrangement, and a patient who declines is owed continued care under existing insurance terms plus help transferring.. 5. Run the member benefit list past the beneficiary-inducement question for every patient covered by Medicare or a state program 7Ref 7U.S. Department of Health and Human Services, Office of Inspector General (2023).General Compliance Program Guidance.The Beneficiary Inducements distinction applied to member perks in a mixed-payer practice: a waiver of a patient charge escapes scrutiny only when it is nonroutine and tied to an individual determination of financial need, an exposure a purely cash-paying panel does not carry.. 6. If opting out is ever plausible, set the program's start date with the quarter boundary in mind 6Ref 6Centers for Medicare & Medicaid Services (2023).42 CFR § 405.410 — Conditions for properly opting-out of Medicare.What opting out requires as a filing: a signed affidavit with each Medicare Administrative Contractor, and for a physician already participating, an effective date only at the start of a calendar quarter on 30 days' notice..
Two of those six are worth an hour with health care counsel before letters go out: the Medicare posture, and the benefit list if any member is covered by a federal program. The rest is drafting and arithmetic.
