Illinois Subscriber Answer: If a patient presents to your practice and requests a second opinion, you should report the appropriate E/M office visit code (99201-99205 for new patients; 99212-99215 for established patients). Because most second-opinion requests are patient-generated, you should treat these office visits as you would any other E/M visit.
Caveat: In some rare cases, you may encounter a physician-generated second-opinion request that can qualify as a true consultation.
According to CMS Transmittal 788, dated Dec. 20, 2005, -In a facility setting, a second-opinion consultation arranged through the attending physician shall be reported by a physician/qualified NPP using an appropriate initial inpatient consultation code [99251-99255] when the consultation requirements are met. When consultation requirements are not met the Subsequent Hospital Care codes (99231-99233) in the hospital setting and the Subsequent NF Care codes (99307-99310) in the NF setting shall be reported.-
