Closing a solo practice: the six-month sequence

The six-month sequence, working backward from your last day

Closing well means running a checklist backward from the day you stop seeing patients. Roughly six months out you set the last clinical date; from there, patient notice, records custody, payer termination, and license wind-down each have their own clock, and several of those clocks are set by your state board rather than by you. Professional associations publish closing-a-practice checklists for exactly this reason 1Ref 1APA Services, Inc. (2026).Practice — APA Services.That a professional practice organization publishes closing-a-practice and practice-transition guidance, anchoring the closure sequence as an established practice-management norm..

Think of it as the inverse of the 12-month runway you ran when you opened: the same domains — patients, records, payers, credentials, money, insurance — closed in reverse. The order matters because the clocks overlap. Payer termination notice can run 90 days; patient notice runs on the board's timeline; the records-retention obligation runs for years after the last visit; and malpractice tail coverage has to be arranged while your policy is still in force.

The path also depends on why you are closing. If you are handing the practice to a buyer, selling is a different transaction with its own diligence and asset transfer. If you are tapering toward retirement, the two-year glide lets you thin the panel gradually rather than in a single notice. And if you are closing because the practice cannot pay its bills, insolvency options reorder the whole sequence — creditors and the entity's debts move to the front. This page assumes a planned, solvent close of a solo practice.

Tell patients first, and mind the abandonment line

Patient notification is the step with the sharpest ethical and licensing edge, because stopping care without adequate notice and a referral path is what licensing boards treat as abandonment. A common convention is written notice at least a month before the last day, but many state boards and professional codes set their own minimum notice period and their own required contents — so the letter's timing and contents are a rule to look up for your state, not a number to guess.

The notice letter to active patients generally does the following work:

• States the last date you will be available for care.
• Explains how to obtain records, with the authorization form and the custodian's contact once care ends.
• Offers a referral path — named colleagues, the state association's directory, or how to find a new clinician — without steering every patient to a single destination.
• Bridges medication, for prescribers, with enough of a refill window to reach a new prescriber, and a specific plan for anyone on controlled substances.
• Names the coverage for the interim if you will be unreachable before the last date.

Send the letter to active patients by a method you can prove — many practices use certified mail for anyone seen recently and first-class for the wider panel. Post the same notice where current patients will see it: the waiting room and the practice website. Some state boards additionally require a public notice in a local newspaper for a set number of weeks; that, too, is a state-specific rule to confirm rather than assume.

Records: custody, retention, and the request window

Your records do not close with your doors. Patients keep their HIPAA right to inspect and obtain copies of their charts after you stop practicing — generally within 30 days of a request, for a reasonable cost-based fee, and in the form they ask for where you can produce it 2Ref 2HHS Office for Civil Rights (2026).Individuals' Right under HIPAA to Access their Health Information.That patients keep the right to access copies of their records within 30 days for a reasonable cost-based fee after a practice closes, with psychotherapy notes excluded from that access right.. Psychotherapy notes remain a separate carve-out outside that access right 2Ref 2HHS Office for Civil Rights (2026).Individuals' Right under HIPAA to Access their Health Information.That patients keep the right to access copies of their records within 30 days for a reasonable cost-based fee after a practice closes, with psychotherapy notes excluded from that access right.. So someone has to stay reachable to answer requests, and the charts have to live somewhere secure for as long as your state requires you to keep them.

The retention period is the part that varies most by state. Professional record-keeping guidance commonly frames retention as several years after the last service for adults and longer for minors — measured, for a minor, from the age of majority — but the binding number is your state's medical-record retention law, and it runs longer when litigation is anticipated. Confirm your state's period before you decide how long storage has to last.

Name a records custodian in writing before you close. This is the custodian arrangement: another licensed clinician, or a professional records company, who agrees in a signed custodian agreement to hold the charts, answer access requests, and honor the retention clock. Tell patients who the custodian is in the closing notice. Arrange secure storage after the practice — a locked physical facility or a HIPAA-compliant electronic vendor under a business associate agreement — and keep the minimum-necessary and secure-disposition duties running until the retention period ends and the records can be destroyed properly 3Ref 3HHS Office for Civil Rights (2026).Summary of the HIPAA Privacy Rule.That the Privacy Rule's minimum-necessary and secure-use-and-disclosure duties continue to govern PHI during records transfer, storage, and secure disposition after closure..

Do not treat handing a patient their full chart as discharging the retention duty. The access right gives the patient a copy; you, or the custodian, still hold the retained record for the state's full window.

Payers, credentialing, and the billing tail

Every payer contract has a termination clause with its own advance-notice requirement, and that notice period is set by your participation agreement, not by a national rule. A large payer such as UnitedHealthcare publishes where its provider policies and protocols live, but the specific termination terms sit in the contract you signed — your contract controls 4Ref 4UnitedHealthcare (2026).UnitedHealthcare Policies and Protocols.Named example that a payer publishes its provider policies and protocols centrally while the specific network-termination and notice terms live in the participation agreement — cited only as this payer's own policy location, with 'your contract controls' framing.. Send written termination to each payer, calendar the effective date, and keep your billing credentials active long enough to work the claims that are still in flight.

The billing tail is the reason you do not deactivate everything on your last clinical day:

• Timely filing. You still have to submit and appeal claims for services already rendered, each within that payer's filing window. Closing the billing entity early strands that revenue.
• Recoupment window. Keep the tax ID and the practice bank account open until the last remittance clears and each payer's post-payment review window has passed.
• Credentialing. Withdraw or set your CAQH profile to not-accepting, and notify each network in writing so you are not auto-rostered into a plan you have left.
• Vendors. Tell your clearinghouse and EHR you are closing; both are business associates, so winding down their access belongs in the plan.

Do not deactivate your NPI until the tail is fully worked — an inactive NPI can bounce a legitimate late claim, and you may still need the number to answer a post-payment audit.

DEA, state licenses, and other registrations

If you prescribe controlled substances, your DEA registration and its recordkeeping obligations do not simply expire quietly when you stop. The DEA Diversion Control Division administers how a practitioner modifies or surrenders a registration, along with the controlled-substance records and inventory that must be reconciled and retained 5Ref 5Drug Enforcement Administration (2026).Diversion Control Division.That the DEA Diversion Control Division administers modification and surrender of a practitioner registration and the controlled-substance recordkeeping and inventory duties that must be reconciled at closure.. Decide before your last prescribing day whether you are surrendering the registration, moving it to a new address, or keeping it active, and reconcile your inventory and dispensing logs against that decision.

The rest of the credential wind-down runs in parallel:

• State professional license. Decide active, inactive, or retired status. Some boards require you to hold a license to release records or to be named as a custodian, so do not let it lapse before the records duty is settled.
• State controlled-substance registration. In many states this is a separate registration from the DEA one, with its own surrender step — another state-specific item to confirm.
• Prescription monitoring program. Close or update your account.
• Business registrations. The DBA, professional-entity dissolution, sales-tax and local business licenses, and any CLIA certificate belong on the list — but the tax and entity-dissolution mechanics are questions for your accountant and attorney, not a form to file blind.

The pattern across all of these: a credential rarely closes itself, and letting one lapse without a decision can leave you technically noncompliant during the exact window you are trying to exit cleanly.

Money, refunds, and malpractice tail coverage

Two money items outlive the practice. First, credit balances and unearned prepayments have to be refunded, and any self-pay patient you still see during the wind-down is still owed a good-faith estimate under the No Surprises Act, with the patient–provider dispute-resolution process sitting behind it 6Ref 6Centers for Medicare & Medicaid Services (2026).No Surprise Billing.That self-pay patients seen during the wind-down are still owed good-faith estimates under the No Surprises Act, with the patient–provider dispute-resolution process behind it.. Second, if your malpractice policy is claims-made rather than occurrence-based, a claim reported after you close is only covered if you bought tail coverage before the policy lapsed.

The malpractice distinction is the one that quietly ends careers, so price it early. An occurrence policy covers any claim arising from an incident during the policy period, whenever it is later reported — nothing more to buy. A claims-made policy covers only claims reported while the policy is active, so closing the practice ends the coverage unless you purchase an extended reporting endorsement, the tail. It is a one-time premium, often a multiple of your annual premium, and some carriers waive it on retirement, death, or disability — confirm your policy's terms before you assume you are covered.

On the cash side: refund credit balances promptly, and check your state's unclaimed-property rules for refunds you cannot deliver, because uncashed patient refunds can become escheatable property. Settle final payroll, vendor invoices, and lease obligations. If the practice cannot cover those debts, that is where insolvency options change the order — resolve the entity's obligations before dissolving it, rather than after.

A closing calendar you can pull real deadlines into

Here is the sequence as a backward-counting calendar, anchored to your last clinical day. Treat the month markers as a common planning frame rather than legal deadlines — the binding dates are the ones your state board, your payer contracts, and your insurer set, and several of them run longer than the six-month default. Pull each real deadline into your calendar as you confirm it, and let the longest one drive the start date.

The calendar is deliberately conservative at the top. If your longest payer notice is 90 days and your board wants 60 days of patient notice, six months gives you room; if a payer notice is longer, or your state requires newspaper publication for a set number of weeks, the whole thing shifts earlier. The mistake is starting from the last clinical day and discovering a 90-day clock you needed to have started months ago.
