Day of service

"An in-patient consultation was done and later on the same day an in-patient surgical procedure was performed. Medicare has paid for the consultation code but has denied payment for the procedure stating that “a CPT or a CPT/modifier combo is not compatible with another procedure or CPT/modifier combo provided on the same day according to the CCI.” The codes used were CPT 99222 and CPT 28820 (T6). Any suggestions?”
