Moonlighting, Locums, and Side Work for California Physicians

A weekend ED shift, a telehealth panel, a locum procedure day, and a paid chart-review agreement may all be called moonlighting. They are not one job. Each can put the physician in a different entity, location, record, authority structure, and reporting period.

Treat every outside role as its own practice pathway. The payment method is the least useful fact. The useful facts are who the patient is, where the patient is, what the physician does, who holds the record, and what happens when the work ends.

Build one row for each role

For every hospital, group, staffing company, platform, clinic, facility, professional entity, or direct client, record the contracting party; patient or work location; service; acuity; procedures; call; first and last patient date; record system; results and after-hours owner; and escalation route.

Add the physician's legal authority, facility privilege if relevant, employer permission if relevant, entity that bills or contracts, and the policy or indemnity arrangement expected to respond. A W-2, 1099, schedule, or platform login does not establish these facts.

Check authority before the first patient, not after onboarding

A California license, an employment agreement, a hospital badge, and a certificate of insurance answer different questions. A current license is the starting authority to practice in California. If the role uses a hospital or facility that requires privileges, the facility's approved process governs that work. A staffing agreement does not create a privilege.

For each clinical role, confirm the service, procedure, site, call duty, EHR and order access, supervising or consulting relationship where relevant, and first permitted date. If any part is uncertain, the shift is not ready for independent patient care.

Treat patient location as a clinical fact in telehealth

California defines telehealth as a way to deliver care and treats the patient's location as the originating site. Before telehealth starts, obtain and document the required consent. Telehealth does not lower the standard of care, expand a clinician's scope, or remove confidentiality and record duties.

When the role includes prescribing, dispensing, or furnishing a dangerous drug, California also requires an appropriate prior examination and medical indication. Telehealth can support that examination only when the standard of care is met.

For a patient located in California, the physician needs current California authority. For a patient in another state, verify that state's current route before providing nonemergent care. Do not assume that a California license, employer approval, platform terms, or a policy territory answers another state's practice rule.

At each remote visit, confirm the patient's current location, a working callback and escalation path, clinical suitability, record custodian, result route, and the clinician or service responsible for follow-up. A video connection does not itself establish or transfer clinical responsibility.

Read the main employment agreement, then the outside contract

The primary employment agreement may address exclusivity, conflicts, outside activities, use of resources, inventions, billing, records, confidentiality, and indemnity. The outside contract can allocate different duties. Read both before accepting the role.

Permission from the primary employer does not mean its policy covers the outside work. Likewise, a staffing company promise of malpractice coverage does not establish who qualifies as an insured, which entity is insured, what clinical services are covered, or how notice works. The issued documents decide.

Make claims-made history visible role by role

Keep a coverage chronology for each assignment: insurer, policy form, service period, insured status, retroactive or prior-acts terms, claims and circumstances contact, limits, and end-of-assignment reporting path. Occurrence coverage generally looks to covered care in the policy period. Claims-made coverage depends on its issued reporting and other terms.

An old assignment may have an ERP, a continuing group policy, a new policy with expressly accepted prior acts, or another arrangement. Do not assume a full-time policy reaches back to side work simply because the physician is the same. Compare the insured person and entity, service, dates, retroactive or prior-acts terms, exclusions, related-acts language, limits, and reporting instructions.

Supervision and medical direction are real work

Outside work can include NP or PA supervision, protocol review, medical direction, test review, telehealth triage, or an arrangement that uses the physician's name. Do not call it administrative if the physician is making or retaining a clinical decision.

Map the actual authority, clinicians, patient population, services, location, record access, emergency escalation, entity, and contract terms. A modest stipend does not narrow a broad clinical responsibility.

An MSO, platform, or other unlicensed entity may support administration, but it cannot make or control the professional decisions California reserves to a physician. A physician may consult with managers but must retain ultimate responsibility or approval. Review productivity, scheduling, and call rules for whether they dictate clinical judgment, patient volume, or hours. The title "medical director" does not solve that clinical-control question.

Close each assignment with a patient handoff

Before the final shift, identify the accepting clinician or service for pending tests, pathology, referrals, medication questions, postoperative care, portal messages, and call coverage. Confirm that the accepting clinician and appropriate backup have authorized record access, and document the effective handoff date. Keep patient communication consistent with the real route.

Preserve authorized copies of the contract, policy identity and reporting instructions, final work date, record-access route, and claims contact after the staffing portal closes. A later legal paper or abnormal result should not depend on a deactivated account.

Restart the review whenever the work changes

Review the pathway when the physician adds an employer, staffing company, entity, procedure, call duty, patient population, site, telehealth state, supervisory role, or period of absence. Also review it when an assignment or policy ends, the carrier or form changes, or the physician changes from employee to contractor or owner.

Before the role ends, document the effective handoff date and who is responsible for unfinished care, record access, clinical decisions, and the reporting path that may apply to prior work.

An outside shift is its own practice pathway.
