Medicare Part B modifiers – 76
Repeat Procedure by Same Physician: The physician may need to indicate that a procedure or service was repeated subsequent to the original procedure or service. This circumstance may be reported by adding the modifier 76 to the repeated service.
Note: When it is medically necessary to repeat a service, the first service should be reported in the usual manner. The repeat service should be reported on the next line with modifier 76 appended to the procedure code. In the event it is medically necessary to repeat a procedure more than twice, report the second line with the 76 modifier and the appropriate number of units in the units field. If a service is repeated more than once, additional documentation should be provided in the narrative field of the claim to support the medical
necessity of the repeat services. The patient’s medical records must always document the medical necessity of performing repeat procedures and be available to the carrier upon request.
Medicare Part B modifiers – 77
Repeat Procedure by Another Physician: The physician may need to indicate that a basic procedure or service performed by another physician had to be repeated. This situation may be reported by adding modifier 77 to the repeated procedure/service.
