CPT Modifier 77

Published 07/16/2020

CPT modifier 77 is used to report a repeat procedure by another physician.

Guidelines and Instructions

  • Submit this modifier to indicate that a basic procedure or service performed by another physician had to be repeated
  • This modifier may be submitted with EKG interpretations or X-rays that require a second interpretation by another physician. Palmetto GBA will reimburse a second interpretation of the same EKG or X-ray only under unusual circumstances, such as a questionable finding for which the physician performing the initial interpretation believes another physician's expertise is needed or a changed diagnosis resulting from a second interpretation of the results of the procedure. Absent these circumstances, Palmetto GBA may reimburse only the interpretation and report that directly contributed to the diagnosis and treatment of the individual patient.
