For modifier 78, which of the following is NOT a requirement?

Modifier 78 is used to identify a return to the operating room for a related procedure during the postoperative period. The key requirement for this modifier is that the procedure must be directly related to the original surgery and must occur within the defined postoperative period. This aspect emphasizes that the additional procedure is part of the same patient care episode initiated by the first surgery.

Regarding option B, it is not a requirement for the procedure associated with modifier 78 to be planned in advance. In fact, procedures covered under modifier 78 may arise from unforeseen complications or problems related to the original surgery, which would not be planned beforehand. This distinguishes modifier 78 from other situations where pre-planning might be more relevant.

The other criteria reinforce the intended use of modifier 78, ensuring that it accurately reflects the nature of the follow-up procedure.
