How to Convert an Insurance-Based Practice to Direct Primary Care (2027)

How Do You Convert an Insurance-Based Practice to Direct Primary Care?

You convert an insurance-based practice to direct primary care by giving notice to your commercial payers under the terms of each contract, deciding whether to opt out of Medicare (which takes an affidavit and private contracts with each Medicare patient), setting a membership price, and telling your patients early enough that they can choose to join. Most physicians plan the switch six to twelve months ahead and budget for a revenue gap while insurance payments run off and memberships build. A hybrid model, where you keep some insurance, is possible but carries real compliance risk.

This guide walks through each piece in the order you will actually face it. It is written for physicians who already have a panel, a building and a team, and who want to move to a membership model without losing the patients and staff they have built up. If you are starting from scratch instead, the 2027 guide to starting a DPC practice covers the full launch.

This is general information, not legal advice. Federal rules are linked to their source, but payer contracts and state laws vary, and a health care attorney should review your plan before you send any notices.

Fully Cash-Based or Hybrid DPC?

The first decision shapes everything after it. A full conversion means you stop billing insurance for professional services, opt out of Medicare if you see Medicare patients, and every patient who stays signs a membership agreement. A hybrid keeps some payer contracts in place while you add a membership.

Hybrids look safer on a spreadsheet because insurance revenue keeps flowing. The tradeoff is that you run two businesses inside one clinic, and the rules about what you may charge an insured or Medicare patient on top of what their plan pays are exactly where hybrids get into trouble.

What are the compliance issues with hybrid DPC?

The core issue is charging a patient a membership fee for something their insurance already pays you to provide. For Medicare, the HHS Office of Inspector General issued an alert on March 31, 2004 warning participating physicians that charging Medicare patients extra fees for services Medicare already covers can violate their assignment agreement. Medicare's own page on concierge care tells beneficiaries that Medicare does not cover membership fees and that doctors who accept assignment cannot charge extra for Medicare-covered services, so the membership fee cannot include charges for items or services Medicare usually covers.

Commercial contracts raise the same question in a different form. Many contracts include hold-harmless or balance billing language that limits what you can collect from a member beyond their cost sharing, and some address membership or access fees directly. Read each contract for those clauses rather than assuming, and have your attorney review the membership agreement against them.

Concierge practices handle this by charging the membership for services Medicare and insurers do not cover, such as extended access or wellness planning, while still billing insurance for covered visits. That is a different model from DPC, and the DPC vs. concierge medicine guide explains where the line sits.

Do You Have to Opt Out of Medicare to Convert to DPC?

You do not have to opt out, but most full DPC conversions that keep Medicare patients do, because opting out is what lets you charge those patients a membership for services Medicare would otherwise cover. The rules sit in 42 CFR Part 405, Subpart D and in Chapter 15, Section 40 of the CMS Medicare Benefit Policy Manual. CMS publishes the list of physicians who have opted out in its opt-out affidavit dataset.

How the Medicare opt-out works

You file an opt-out affidavit, meeting the requirements of 42 CFR 405.420, with every Medicare Administrative Contractor (MAC) you would otherwise bill. The timing depends on your enrollment status, under 42 CFR 405.410:

• Participating physicians can opt out only at the start of a calendar quarter, and the affidavit must reach the MAC at least 30 days before that quarter begins.
• Nonparticipating physicians can opt out at any time. The opt-out starts on the date the affidavit is signed, as long as it is filed within 10 days after signing the first private contract with a Medicare patient.

Each opt-out period lasts two years and renews automatically. To stop it from renewing, you send written notice to each MAC at least 30 days before the current period ends, as 42 CFR 405.445 describes. A physician opting out for the first time can also terminate within 90 days of the start of the first period, but must refund amounts above the Medicare limiting charge and notify every patient who signed a private contract.

The private contract with each Medicare patient

Every Medicare patient you see after opting out signs a private contract before you provide care. 42 CFR 405.415 lists what it must say, including that the patient will not submit a claim to Medicare, that Medicare will not pay, and that the patient can still get Medicare-covered care from other physicians who have not opted out. It must be signed before services and cannot be signed while the patient faces an emergency or urgent care situation.

Keep a copy of every contract for the full two-year period. Under 42 CFR 405.435, knowingly submitting a Medicare claim or failing to use proper contracts can nullify the opt-out for the rest of the period. Emergency and urgent care for a patient without a private contract follows separate rules in 42 CFR 405.440.

Two practical consequences are worth planning around. Opting out applies to all of your Medicare patients, not a chosen few, and Medicare Advantage plans cannot pay opted-out physicians either, under 42 CFR 422.220. Ask your MAC how ordering and referring for labs, imaging and durable medical equipment will work for your Medicare patients after the switch, since that is the question patients ask first.

How Do You Leave Commercial Insurance Contracts?

Each payer contract has its own termination clause, and the notice period, the required delivery method and any obligations after termination are written in that clause. Pull every contract, including those signed through an IPA, PHO or network, and make a list of each termination notice period, where notice must be sent and whether the contract requires you to keep treating members for a time after termination.

Some contracts are "without cause" terminations with a fixed notice period, and others only allow termination at renewal. Some include continuity-of-care obligations for patients in active treatment. Do not rely on a typical number you heard from a colleague, because the contract you signed is the one that binds you.

Send notices by the method each contract requires, keep proof of delivery, and set your switch date to fall on or after the latest termination date. Also tell your state Medicaid program if you are enrolled, since Medicaid managed care and fee-for-service enrollment have their own rules, and check your state's DPC statute in the direct primary care laws by state guide.

Step-by-Step Conversion Timeline

This is a planning timeline, not a legal deadline. Adjust it to the longest notice period in your contracts and the opt-out timing above.

How Many Current Patients Will Convert to DPC?

There is no reliable national figure for how many insured patients follow their physician into a membership, and published anecdotes vary widely by town, payer mix and price. Plan from your own panel instead.

Start by counting patients actually seen in the last 18 to 24 months, not every chart in the EHR. Then segment them, because conversion tends to differ by group. Uninsured and high-deductible patients often see the value quickly, patients with rich employer coverage may stay with their plan, and Medicare Advantage patients face the extra step that their plan will not pay an opted-out physician outside emergency or urgent care.

A short, honest survey before the announcement tells you more than any average. Ask whether the patient would join at your planned price, what would make them hesitate, and whether they already have a high-deductible plan. Build the budget on a conservative share of the people who say yes, and run a second scenario where fewer join, so a slow first quarter does not put payroll at risk. The DPC break-even panel size guide shows how to turn that estimate into a monthly target.

How Should You Tell Patients You Are Switching to DPC?

Tell patients early, in plain words, and from you rather than a form letter. Expect some patients to leave, and say so to yourself and your team ahead of time, because a patient choosing their insurance plan is a reasonable decision and not a judgment on the care you gave.

A good announcement letter explains why you are making the change in terms of what patients gain (time, access, direct contact), what the membership costs and includes, what is not included (hospital care, specialists, imaging and labs billed elsewhere), the date insurance stops, and how to join. For Medicare patients, it should also explain the private contract and that they can keep using Medicare with other doctors.

Pair the letter with an FAQ page, a few information sessions in the evening or online, and scripts for the front desk so every patient hears the same answers. Give patients who decide not to join a clear path to transfer their records and a list of nearby practices taking new patients, which keeps goodwill and meets your duty not to abandon anyone mid-treatment.

How Much Does It Cost to Convert an Existing Practice to DPC?

The biggest cost of converting is usually not equipment, since you already have a building, an exam room and a team. It is the gap between insurance revenue winding down and membership revenue building up, plus the one-time costs of legal review, new billing software, patient communication and any staffing changes. The cost to start a DPC guide breaks down the one-time line items.

Building the cash flow bridge

Insurance receivables for visits before your switch date keep paying for a while after you stop seeing patients under those contracts, which softens the first months. Memberships, on the other hand, usually start slower than physicians hope and build as patients make up their minds.

Model it month by month for at least the first year. Put receivables runoff in one line, membership revenue at your conservative enrollment estimate in another, and every expense in the rows below. The low point in that forecast is the size of the bridge you need, from savings, a line of credit arranged before the switch, or a temporary reduction in owner pay. Pricing drives all of this, so set it with the DPC membership pricing guide.

Staffing changes

A DPC panel is smaller and claims work disappears, so the mix of roles changes. Billing and coding staff are the hardest conversation. Many practices offer them a new role in membership billing, patient onboarding or care coordination, since the skills of chasing details and talking with patients carry over. Give staff the plan early, before patients hear it, so they can answer questions with confidence.

What to tell your EHR and billing vendors

Call your EHR vendor before you sign anything new. Ask whether your plan supports recurring membership billing, whether you can drop the claims and clearinghouse modules, what it costs to export your data if you change systems, and how long your current contract runs. The DPC EHR comparison for 2027 covers which systems handle memberships natively.

Tell your clearinghouse and any outside billing company the date new claims stop, and agree on who works the remaining receivables and denials until they close. Keep your old system accessible, or export a complete record, for as long as your record retention obligations require.

Does the Switch Affect Patients With HSAs?

Yes, and it changed in a helpful direction. The One Big Beautiful Bill Act (Public Law 119-21) made direct primary care service arrangements that meet the law's conditions compatible with health savings accounts starting January 1, 2026, and capped the monthly fee for members who want to keep contributing. IRS guidance is in Notice 2026-5.

The cap is 150 dollars per month for one person and 300 dollars per month for a membership covering more than one person, and IRS Rev. Proc. 2026-24 kept both figures the same for 2027.

That matters for converting practices because many of the insured patients you hope to keep are on high-deductible plans. The 2027 DPC and HSA rules guide covers the current cap, which services are excluded and how to word your membership so it qualifies.

Keeping the Work From Slipping During the Switch

A conversion runs on follow-up. Every patient who said "maybe" needs a second conversation, every signed agreement has to reach billing, and every Medicare private contract has to be filed where you can find it during the two-year period. During the switch your team is also still working insurance claims, so the old and new systems are both busy at once.

This is where Tabflows helps. It is a dedicated tech team that connects the tools a clinic already uses (EHR, billing, messaging) so the work between them gets done, with follow-ups, tasks and patient context in one place. It is not an EHR or a billing system, so it works with whatever you choose for the new model.

Once you are running, the DPC Finder is a directory of every DPC practice, which is a good place to list the clinic and to see how practices near you price and describe their memberships.
