That would be the Inpatient Consultation codes 99251 through 99255. However, effective 2010, Medicare stopped reimbursing consult codes 99241-99245 (outpatient consults) and 99251-99255 (Inpatient consults). Medicare must be billed with Initial Hospital Service codes 99221-99223. In addition, the primary physician of record (PPOR) who admits the patient must continue to use those same codes and append the modifier AI to the code. Services on subsequent days would be billed by both PPOR and consultant using Subsequent visit codes 99231-99233.
