Selling a Medical Practice in California

On the first Monday after closing, an old patient may have postoperative pain, an abnormal pathology result may return, and a former employee may receive a legal paper. The sale should already answer who acts, where the record is, which entity controls clinical decisions, and how the historical policy can receive a notice.

A purchase agreement can allocate commercial obligations. It cannot by itself transfer professional judgment, make a buyer eligible to practice medicine, create a patient handoff, assign a payer or facility privilege, or manufacture an insurance reporting right.

Decide what can change and what must remain clinical

Map the post-close medical practice, buyer or MSO role, property and equipment entities, record custodian, clinicians, locations, and services. California's corporate-practice rules require a California-licensed physician to retain ultimate responsibility for or approval of the professional decisions the Medical Board identifies. An unlicensed entity may not control diagnostic tests, referrals, treatment, patient volume, record content, clinical staffing competency, patient-care coding and billing, or clinical equipment and supplies.

This is not a generic deal template. The permitted structure depends on the actual entities and transaction. Have California counsel experienced in healthcare corporate-practice rules validate the ownership, management, asset, and contract structure before closing. The physician's operational question is simpler: can the post-close practice show who holds final authority for the patient-care decisions the Board identifies?

Build the close schedule around care, not the closing date

Make three separate timelines. The patient-care timeline includes final seller visit, call, prescription, open results, referrals, postoperative care, and buyer's first care. The contract and authority timeline includes closing, employment, leases, vendor and facility contracts, privileges, and access. The insurance timeline includes final covered service, insured-status change, policy expiration, claim or circumstance notice, ERP election if offered, and buyer-policy or prior-acts decision.

No one date controls all three. If the seller works for the buyer after closing, identify the exact role, entity, site, record access, policy terms, and first date that apply to each period.

Transfer custody without abandoning access

Create an active-care register before EHR access changes. Include pending pathology, laboratory and imaging results, referrals, procedure aftercare, medication monitoring and refills, messages, call coverage, hospitalized patients, future appointments, and adverse-event follow-up. For each item, name the current clinician, backup, record route, patient communication, and closure condition.

The Medical Board advises physicians who close or depart a practice to minimize disruption, give patients appropriate notice, identify record storage and access, and help patients obtain ongoing care. For physicians and surgeons, California requires adequate and accurate service records for at least seven years after the last date of service and protects patient access to records. These rules do not mean that a seller should export records merely for defense convenience. Establish lawful custody, authorized access, confidentiality, patient-request process, backup and export plan, and a limited route for future defense needs.

Read the sale agreement beside the policies

The agreement may allocate tail cost, cooperation, indemnity, deductibles, records, notice, and future claim support. The issued policy decides whether an insured has coverage, a reporting right, or an ERP. Read them side by side.

For seller and buyer policies, compare the form, insured people and entities, historical service period, retroactive or prior-acts terms, claims and circumstances definitions, related-acts language, ERP availability and election terms, limits and aggregate, defense and deductible treatment, exclusions, claims contact, and notice method. Do not assume an application, binder, certificate, or agreement extends the reporting path. Preserve the issued documents.

Occurrence coverage generally responds to covered care in its policy period, subject to its terms. Claims-made transitions depend on the actual reporting, retroactive, known-event, named-insured, entity, limit, and ERP or prior-acts provisions. A seller tail and buyer prior-acts coverage may be possible but are not automatic or equivalent.

Recredential work that continues after closing

For each physician, NP, PA, contractor, and employee, record the post-close employer or contracting entity, services, site, competence, privileges, record queues, call and prescription coverage, and first or last role date. Same staff does not mean the same authorization.

Recheck NP pathway and setting conditions, PA practice agreement, furnishing authority, competence, supervision, facility privileges, and system access where they apply. A sale does not grandfather the prior clinical model. Use the NP/PA guide for role-specific analysis.

Run administrative tracks only when they apply

If the practice or clinician participates in Original Medicare, determine the relevant supplier, transaction type, enrollment or reassignment path, MAC direction, CMS form or PECOS process, and effective date. CMS-855R has been discontinued and reassignment is handled through PECOS or CMS-855I. Medicare enrollment does not establish commercial payer status, facility privileges, licensing, or insurance.

Apply the same conditional approach to commercial payers, laboratories, pharmacies, devices, facilities, DEA registrations, leases, and vendor agreements. Do not assume that a schedule, credential, payer network, contract, or policy assigns automatically. Check consent, assignment, termination, credentialing, and effective-date terms.

Test the first week after closing

Simulate a late legal paper, urgent postoperative call, abnormal lab, record request, patient complaint, refill, and vendor outage. Verify the current clinician, lawful record route, former-policy reporting contact, entity, and coverage document that may apply.

The sale is complete only when each of those events has a current clinical recipient or operational contact and a documented path. The transaction can then support care rather than interrupt it.

A sale changes the business; it cannot leave a patient without a clinician.
