Medicare audits of teaching hospitals and resident-staffed clinics increasingly turn on one question: was the teaching physician actually present for the part of the visit that determines the billed level of service. Under 42 CFR 415.172, Medicare pays for a resident's work only when the teaching physician was physically present during the critical or key portion of the service. A resident's note describing a thorough encounter does not establish that presence, and when a reviewer cannot find it documented, the claim is recharacterized as one the physician did not furnish.
The Presence Requirement
The presence standard is not uniform across service types. For surgical procedures, the teaching physician must be present for all critical portions and immediately available for the rest. For evaluation and management visits, presence is required during the portion that determines the level billed. For time-based codes, such as critical care services (CPT 99291 and 99292) and hospital discharge day management (CPT 99238 and 99239), Medicare pays only for the period the teaching physician was physically present; time a resident spends alone with the patient does not count. When total time selects the office or outpatient E/M level, only teaching-physician-presence time counts.
Documentation That Does Not Establish Presence
The medical record must demonstrate that the teaching physician performed the service, or was physically present during the critical or key portions a resident provided, and participated in managing the patient. Other team members may document the teaching physician's presence, but the physician must sign and date the entry with a legible signature or identity verification. A documentation macro that automatically generates predetermined text is not sufficient on its own: the note must add patient-specific information supporting medical necessity.
The GC and GE Modifiers
Claims for a service a resident performed in part under a teaching physician's direction must carry the GC modifier, which certifies that the teaching physician met the presence and documentation requirements in 42 CFR 415.172. Claims for a service a resident performed independently under the primary care exception described below must carry the GE modifier instead. Because the modifier is itself an attestation about what happened during the visit, a mismatch between the modifier and the documented facts, such as a GC modifier on a visit the physician never entered, calls the claim into question.
The Primary Care Exception
A narrow exception at 42 CFR 415.174 lets a teaching physician bill for lower- and mid-level E/M visits a resident provides without the teaching physician present, in a hospital outpatient department or similar ambulatory care entity tied to the teaching hospital's graduate medical education payments. The resident must have completed more than six months of an approved residency program, the teaching physician cannot supervise more than four residents at a time, and must review the resident's care during or immediately after each visit. The visit level is selected using medical decision making only, never time, and billing is limited to new patient levels 2 and 3 (CPT 99202 and 99203) and established patient levels 1 through 3 (CPT 99211 through 99213); levels 4 and 5 cannot be billed under the exception.
The presence requirement is satisfied only by a contemporaneous record of what the teaching physician personally did, never by a resident's description of a thorough visit.
What Auditors Reconstruct
When Medicare Administrative Contractors and Recovery Audit Contractors (RAC) test teaching physician claims, the presence requirement they apply comes from the Code of Federal Regulations and the Medicare Claims Processing Manual, not from a local coverage determination, so it applies the same way in every contractor jurisdiction. An unsupported GC modifier on a sample of claims can become the basis for extrapolation across the full claims population, and the resulting recoupment demand can reach far beyond the claims a reviewer actually examined. A pattern of unsupported claims can also lead to a corrective action plan.

Why Early Legal Counsel Is Critical
It is critical that healthcare providers promptly retain experienced healthcare defense counsel upon receiving a subpoena, audit notice, investigative request, or other government inquiry. Early legal intervention can protect the provider's rights, support appropriate responses to government requests, avoid inadvertent admissions, preserve relevant defenses, and allow counsel to communicate with investigators on the provider's behalf. Delaying legal representation can significantly affect the outcome of a matter and expose the provider to unnecessary risk.
