Supervision Requirements (Medicare or State)

Physicians increasingly rely on nurse practitioners, physician assistants, and clinical staff to expand access and grow their practices. Before a practice delegates care or bills for services performed by others, however, it must satisfy two separate sets of supervision rules: the requirements of the payer, particularly Medicare, and the licensure requirements of the state where the patient is treated.

These two systems do not always align. A nurse practitioner may be fully authorized under state law to practice without a physician, while Medicare still requires a physician’s direct supervision before those same services can be billed under the physician’s name. Conversely, Medicare may permit a service to be billed, while state law requires a written practice agreement that the practice never signed.

Supervision failures can lead to Medicare overpayment demands, False Claims Act exposure, licensing board discipline, and disputes between practices and their clinicians. G2Z Law Group assists physicians, advanced practice providers, medical practices, and health care organizations with structuring and documenting compliant supervision arrangements.

What Is the Difference Between Medicare Supervision and State Supervision?

They answer different questions.

State supervision and collaboration laws determine whether a clinician is legally permitted to provide a service, and under what physician involvement. These rules are set by state licensing boards and vary widely by profession and jurisdiction.

Medicare supervision rules determine whether, and under whose name, a service can be billed and paid. A practice must comply with both. Satisfying state law does not establish that a Medicare claim is proper, and a properly billed Medicare claim does not cure a state licensure violation.

What Levels of Supervision Does Medicare Recognize?

Medicare generally recognizes three levels of supervision, defined in its rules for diagnostic tests and applied across many other services:

  • General supervision: the service is furnished under the physician’s overall direction and control, but the physician’s presence is not required.

  • Direct supervision: the physician must be immediately available to furnish assistance and direction throughout the service.

  • Personal supervision: the physician must be physically present in the room during the service.

The required level depends on the service, the setting, and how the service is billed.

What Is “Incident-To” Billing?

Incident-to billing allows certain services performed by nurse practitioners, physician assistants, and clinical staff in an office setting to be billed under the supervising physician’s name and paid at the physician rate. In exchange for the higher payment, Medicare imposes strict conditions. Among other things:

  • the service must be an integral part of a course of treatment the physician initiated;

  • the physician must remain actively involved in the patient’s care;

  • the service generally must be furnished under the physician’s direct supervision; and

  • the person performing the service must be an employee, leased employee, or independent contractor of the physician or practice.

New patients and new problems generally cannot be billed incident-to. Incident-to billing is a frequent audit target, and errors can affect every claim billed under the arrangement.

Can Direct Supervision Be Provided Virtually?

Yes, for most services, as of January 1, 2026.

In the CY 2026 Medicare Physician Fee Schedule final rule, CMS permanently revised the definition of direct supervision so that the supervising physician or practitioner may be immediately available through real-time, two-way audio and video technology instead of being physically present. Audio-only communication does not qualify, and services with 10-day or 90-day global surgery periods are excluded.

Virtual supervision does not relax the other incident-to requirements, and it does not change what state law requires. Practices relying on remote supervision should document their technology, availability, and protocols.

Can Nurse Practitioners and Physician Assistants Bill Medicare Directly?

Yes. Nurse practitioners and physician assistants may enroll in Medicare and bill under their own provider numbers, typically at a reduced percentage of the physician fee schedule. Billing directly avoids many incident-to conditions, but it still requires that the clinician be practicing within the scope and supervision requirements of state law.

Do Nurse Practitioners Need Physician Supervision in Virginia?

It depends on experience.

Under Virginia law, a nurse practitioner generally must practice under a written or electronic practice agreement with a patient care team physician that includes periodic review of patient charts. A nurse practitioner who has completed the equivalent of three years of full-time clinical experience may apply for authorization for autonomous practice, supported by an attestation from the collaborating physician. Virginia reduced this requirement from five years to three in 2024.

Certified nurse midwives, certified registered nurse anesthetists, and clinical nurse specialists are subject to their own rules.

What About Physician Assistants in Virginia?

Virginia physician assistants generally must practice as part of a patient care team under a written or electronic practice agreement with one or more patient care team physicians or podiatrists. The agreement must address the PA’s scope of practice, periodic chart review, collaboration and consultation, and performance evaluation.

In 2026, Virginia enacted a law allowing physician assistants with three years of full-time clinical experience to practice without a practice agreement within their clinical specialty. However, that law does not take effect until the Board of Medicine adopts implementing regulations. Until then, Virginia PAs remain subject to the practice agreement requirement.

What Are the Rules in the District of Columbia?

The District of Columbia grants nurse practitioners full practice authority, meaning they may evaluate, diagnose, and prescribe without a physician collaboration agreement. Physician assistants in the District, by contrast, practice under a written delegation agreement with one or more supervising physicians that identifies the PA’s delegated functions and practice sites.

Practices operating in more than one jurisdiction must apply the rules of the state where the patient is located, which may require different agreements for the same clinician.

What Should a Practice Agreement or Supervision Arrangement Include?

Requirements vary by state and profession, but a well-drafted arrangement typically addresses:

  • the clinician’s scope of practice and any limits on procedures or prescribing;

  • the identity and availability of each collaborating or supervising physician;

  • chart review frequency and documentation;

  • referral and emergency protocols;

  • coverage when the physician is unavailable or the relationship ends;

  • compensation for supervision services, structured to comply with anti-kickback and self-referral laws; and

  • how the arrangement aligns with the practice’s Medicare and commercial billing.

Why Should Health Care Practices Be Careful?

Supervision problems tend to be discovered after the fact, through payer audits, patient complaints, or the departure of a supervising physician. At that point, the practice may face repayment of claims billed incorrectly, discipline against both the physician and the advanced practice provider, and gaps in coverage that interrupt patient care.

Supervision arrangements that look informal on paper can also raise fraud and abuse concerns when a physician is paid for “supervision” that is not actually provided.
