Modifier 25 Fact Sheet


  • Significant, separately identifiable evaluation and management (E/M) service by the same physician* on the day of a procedure

*Same physician - Medicare regulation states: "Physicians in the same group practice who are in the same specialty must bill and be paid as though they were a single physician."

All E/M services provided on the same day as a procedure are part of the procedure and Medicare only makes separate payment if an exception applies.

Appropriate Usage

  • Modifier 25 indicates that on the day of a procedure, the patient's condition required a significant, separately identifiable E/M service, above and beyond the usual pre and post-operative care associated with the procedure or service performed.
  • Use Modifier 25 with the appropriate level of E/M service.
  • The procedure performed has a global period listed on the Medicare Fee Schedule Relative Value File. This global period could be 000, 010, or 090 days.
  • An E/M service may occur on the same day as a procedure and within the post-operative period of a previous procedure. Medicare allows payment when the documentation supports the 25 modifier and the 24 modifier (unrelated E/M during a post-operative period.)
  • Use Modifier 25 in the rare circumstance of an E/M service the day before a major surgery that is not the decision for surgery and represents a significant, separately identifiable service.

Inappropriate Usage

  • A physician other than the physician* performing the procedure.
  • Documentation shows the amount of work performed is consistent with that normally performed with the procedure.

The following statements are false

  • I can always use this modifier when I did not plan the procedure.
  • I can always use this modifier when the diagnoses are different.
  • I can never use this modifier when the diagnoses are the same.

Procedure codes:

  • G0181-G0182    Care Plan Oversight Supervision
  • 92002-92014     E/M Ophthalmology
  • 99201-99499     E/M all locations

Example: The physician sees the patient for a condition requiring a significant and separately identifiable E/M service prior to removing a wart.

Special situations

Occasionally two physicians in the same group with the same specialty (but different subspecialties) see the patient on the same day. Medicare does not recognize subspecialties on front-end claims processing. The physician may use Modifier 25 if the documentation meets the definition above. Please submit the documentation when requesting a redetermination.

Situations occur when it is necessary to report multiple surgery modifiers on the same claim line.

The following is an example of appropriate reporting of both modifiers 24 (Unrelated E/M by the same physician during a postoperative period), and 25 (Significant, separately identifiable E/M by the same physician on the same day of the procedure or other service), on the same E/M code.

A physician performs a major surgery and within the global period sees the patient for an unrelated E/M visit. During this unrelated E/M visit, the physician determines the necessity of a minor surgery or other procedure. This minor surgery/other procedure is significant and separately identifiable from the E/M and unrelated to the original major surgery. Both the 24 and 25 modifiers are appropriate to add to the E/M code. The 24 modifier is appropriate because the E/M service is unrelated and during the postoperative period of the major surgery. The 25 modifier is necessary to identify that the minor surgery/procedure performed on the same day is separately identifiable from the E/M service. In addition, the minor surgery procedure code may need a 79 modifier to indicate the procedure is not related to the major surgery.
