Concierge Medicine Billing in 2026

Splitting Insurance Claims From the Retainer, and the New DPC HSA Rule

By Team Rcmaxis  ·  October 17, 2026  ·  12 min read

If a Medicare patient's retainer fee turns out to cover anything your practice already bills Part B for, every one of those claims is a problem under the federal beneficiary inducement law, and the statutory penalty starts at $10,000 per violation (42 U.S.C. § 1320a-7a(a)(5)), adjusted for inflation every year. A concierge program with 400 Medicare patients and one badly worded retainer clause isn't a $10,000 problem. It's a $10,000-times-hundreds problem, and that's before anyone looks at the False Claims Act exposure sitting on the Part B claims themselves.

Concierge medicine billing isn't complicated because the medicine is complicated. It's complicated because you're running two billing systems side by side: one that goes to insurance for covered care, and one that doesn't, for a membership-style fee that's supposed to stay completely separate. Blur that line and you don't just lose revenue. You create an audit trail that writes itself.

Here's how the split actually works, what the retainer can and can't pay for, what OIG has said about fee arrangements like this, and why the new 2026 rule letting HSA dollars pay for direct primary care doesn't mean what a lot of practices think it means for a concierge retainer.

Concierge Medicine vs Direct Primary Care: Why the Billing Split Matters

These two models get lumped together constantly, and the mix-up causes real billing mistakes. If your practice runs a pure membership model with no insurance billing at all, read our direct primary care billing guide instead; everything below assumes you're still billing Medicare or commercial insurance for covered visits.

Direct primary care (DPC) replaces insurance billing for primary care entirely. The patient pays a flat monthly fee, the practice doesn't bill any insurer for primary care visits, and the fee is the only money changing hands for that care. Concierge medicine is a hybrid: the practice keeps billing insurance or Medicare for the E/M visit itself, and layers a separate retainer or membership fee on top for things insurance never covered in the first place, like same-day scheduling, 24/7 physician access, longer appointments or an executive-style annual physical.

That hybrid structure is exactly what makes concierge billing riskier than DPC billing. A pure DPC practice has no insurance claims to cross-check against the membership fee. A concierge practice has both, running in parallel, and a payer or an OIG investigator can line them up side by side and ask whether the retainer quietly duplicates something already paid for on a claim.

What the Retainer Can and Can't Cover

The dividing line is simple to state and genuinely hard to enforce in daily practice: the retainer pays for access and amenities, never for medically necessary care that a payer already covers. Here's how that typically breaks down.

Run the arithmetic on a typical panel. A concierge physician with 300 retainer patients charging an average $3,000 a year in membership fees is billing $900,000 a year in retainer revenue, completely separate from whatever that same panel generates in E/M and preventive-service claims. That retainer income is real and legitimate, right up until an auditor finds one amenity on the fee schedule that quietly overlaps a billed CPT code. Then the exposure isn't the retainer fee; it's every claim billed to every patient under that same agreement language.

Billing the E/M Visits That Go to Insurance

The claims you send to Medicare or a commercial payer for a concierge patient look exactly like claims for any other patient. Code the visit on medical necessity and documented time or complexity, the same as you would without a retainer agreement in place. The retainer doesn't change the code, the modifier or the documentation standard for a single covered service.

Where practices slip up is in how the two revenue streams get described to the patient and to the payer. If your financial policy, website or patient agreement describes the retainer as covering "unlimited visits," "all office visits" or "priority access to care," a payer or auditor can read that as a description of the medically necessary visit itself, not just the amenities around it. Keep the retainer agreement's language narrowly about access, amenities and non-covered extras, and keep a completely separate explanation of benefits process for the insurance side.

Document covered visits with the same level of detail you'd use for any patient: history, exam, medical decision-making or time, and medical necessity for every code billed. A thin note on a concierge visit looks worse to a reviewer than a thin note on a regular visit, because the reviewer is already primed to ask whether the retainer bought the visit instead.

OIG and Anti-Kickback Exposure: What Auditors Look For

The federal government has been watching retainer-fee medicine for more than two decades, and the legal theory hasn't changed even as the models have multiplied. The core question is always the same: did the fee buy something the patient was already entitled to under Medicare, or did it buy something genuinely extra?

Trade press coverage of a 2002 HHS Office of Inspector General alert describes OIG warning physicians that charging a flat fee for services Medicare would otherwise cover "could be a problem." OIG's chief counsel later clarified that the alert wasn't a blanket condemnation of concierge medicine, only of charging for already-covered care, and HHS officials at the time suggested a retainer fee limited to genuinely non-covered services wouldn't violate Medicare law. That's the line concierge practices have built their billing models around ever since, even without a formal safe harbor written specifically for primary care retainers.

More recently, OIG Advisory Opinion 26-12, issued in May 2026, approved a concierge program run by an orthopedic surgical practice: a one-year post-surgical concierge fee covering only items and services the requestor certified were not covered by any insurer, including Medicare, structured as a warranty-style refund if a patient needed revision surgery. OIG found the arrangement wouldn't trigger the Anti-Kickback Statute or the Beneficiary Inducements CMP, largely because of that clean non-covered certification and the warranty safe harbor's refund structure. The opinion only binds that one requestor, and it's a surgical specialty case, not a primary care one, but the reasoning maps directly onto any concierge model: certify, in writing, that nothing in the retainer duplicates a covered benefit, and be ready to prove it.

The 2026 DPC HSA Rule, and Why It Usually Doesn't Cover Your Retainer

Here's the part that trips up a lot of concierge practices marketing themselves right now. The One Big Beautiful Bill Act added Section 223(c)(1)(E) to the Internal Revenue Code, and for months beginning after December 31, 2025, a qualifying direct primary care service arrangement (DPCSA) is no longer treated as a disqualifying health plan, which means someone enrolled in one can still contribute to an HSA. The IRS followed up with Notice 2026-5 in December 2025, clarifying the mechanics.

The dollar caps matter for anyone quoting a retainer price: $150 a month for an arrangement covering one individual, $300 a month for one covering more than one person, aggregated across every DPC-style arrangement a person holds. Go over the cap, even by stacking two arrangements, and the person loses HSA eligibility entirely for that period, not just for the amount over the cap.

Now the catch for concierge medicine specifically: the statute requires the fixed periodic fee to be the arrangement's sole compensation for primary care, and the guidance excludes arrangements that bill separately for services inside that scope. A concierge model that bills Medicare or insurance for the E/M visit and charges a retainer on top is, by definition, billing separately for primary care services. That generally keeps a concierge retainer out of the DPCSA definition Congress just created, which means the retainer fee itself usually isn't the kind of HSA-eligible expense a true DPC membership fee now is. If your patients ask whether they can pay your retainer from an HSA, the honest answer for most concierge structures is: not under this specific rule, because your model bills insurance alongside it. A patient's existing HSA might still reimburse qualified medical expenses billed through insurance, like deductibles or copays, but that's a different, older rule, not the new DPCSA provision.

This is worth getting right before you market it. Telling patients their membership is "HSA-eligible under the new 2026 law" when your practice also bills their insurance for visits is a marketing claim that doesn't match the statute, and it's an easy thing for a sharp patient's tax preparer to flag.

Build the Billing Workflow

Running both revenue streams cleanly comes down to process, not clever coding. Put the retainer billing (usually a simple recurring charge, often through a separate billing system or module) on a completely different workflow from your claims billing, and never let the two teams, invoices or system logins blend together.

Code and bill insurance claims the same way you would for any patient, with full documentation support. Keep the retainer agreement, the patient financial policy and the EOB/claim history in a format that an auditor, or your own compliance officer, could review independently and see no overlap. Revisit the agreement annually, ideally alongside your health care attorney, especially if you add any new amenity.

• Separate the billing systems. Retainer charges and insurance claims should never run through the same line-item logic.
• Audit your own agreement once a year. Read it as if you were the OIG investigator, not the practice that wrote it.
• Train every front-desk and billing staff member on the exact boundary. Script the answer to "is this covered by my membership" so nobody improvises.
• Track retainer revenue and insurance revenue separately in your financial reporting. If a reviewer ever asks for the split, you want the answer in minutes, not days.

Frequently Asked Questions About Concierge Medicine Billing

Can a concierge medicine practice bill Medicare and charge a retainer fee at the same time?

Yes, as long as the retainer only pays for things Medicare doesn't cover, like same-day access, longer visits, direct texting with the physician or an annual executive-style wellness exam beyond what Medicare's Annual Wellness Visit includes. The moment the retainer pays for anything that overlaps a covered, medically necessary service, you have a double-billing and beneficiary-inducement problem.

Is a concierge medicine retainer fee eligible for HSA reimbursement under the 2026 DPC rule?

Usually not. The OBBBA's HSA-compatible direct primary care rule (IRC Section 223(c)(1)(E), effective for months after December 31, 2025) requires the fixed periodic fee to be the sole compensation for primary care, with no separate billing for services inside the arrangement. A concierge model that also bills insurance for covered visits typically fails that sole-compensation test, so the retainer itself is usually not HSA-eligible the way a true direct primary care membership fee is.

What's the difference between concierge medicine billing and direct primary care billing?

Direct primary care replaces insurance billing for primary care with a flat membership fee and bills no insurance for covered visits. Concierge medicine keeps billing insurance or Medicare for covered E/M visits and adds a separate retainer fee on top for non-covered access and amenities. The two models have different compliance rules, different HSA tax treatment and different claim structures, so they need separate billing workflows.

What is the penalty for charging a Medicare patient a fee that duplicates a covered service?

Charging or waiving fees in a way that induces a Medicare beneficiary to use your services can trigger the Civil Monetary Penalties Law's beneficiary inducement provision, with a statutory penalty starting at $10,000 per violation under 42 U.S.C. Section 1320a-7a(a)(5), adjusted for inflation, plus potential False Claims Act exposure on the underlying Part B claims. The practical fix is a retainer agreement that never overlaps a billable service.
