Coding Note

From the College  |  Issue: April 2010  |  April 1, 2010

As of January 1, 2010, Medicare eliminated both inpatient and outpatient consultation codes. Both the admitting physician and the consulting physicians who perform an initial evaluation and management service should bill the initial hospital care codes (99221–99223), but the admitting physician will have to place the –AI modifier on his or her claim. As a result of this change, multiple billing of initial hospital and nursing-home visit codes can occur in a single day. The Center for Medicare and Medicaid Services created the “AI” modifier to be used by the admitting or attending physician who oversees the patient’s care as distinct from other physicians who may be furnishing specialty care. The “AI” modifier is defined as “Principal Physician of Record.”
