What are examples of modifier 25 usage?


Editorial team Published on

Modifier 25 is appended to an Evaluation and Management (E/M) service code (such as CPT 99212–99215) to show that a physician or qualified healthcare professional provided a significant, separately identifiable E/M service on the same day as another procedure or service, going above and beyond the usual pre-op or post-op care linked to that procedure. It is attached only to the E/M code, never the procedure code.

Examples of Appropriate Usage (When You CAN Use Modifier 25)

  • New Problem Discovered During a Procedure Visit:
    • A patient arrives for a scheduled minor surgical procedure (e.g., skin lesion removal). During the visit, the patient mentions a severe, unrelated acute issue (e.g., acute wheezing or a painful, swollen left ankle). The physician evaluates and manages the new problem, decides on a treatment plan for it, and still performs the scheduled lesion removal.
    • Billing: Report the minor procedure code + the E/M code (e.g., 99213 -25) supported by separate documentation for the ankle/wheezing evaluation.
  • Preventive Exam Combined with Problem-Oriented Visit:
    • A patient comes in for an annual preventive medicine visit (annual physical/wellness exam). During the discussion, the patient brings up a chronic or acute condition that needs distinct medical decision-making (e.g., uncontrolled hypertension or new-onset joint pain).
    • Billing: Report the preventive visit code alongside the established patient office visit code appended with Modifier 25 (99213 -25), showing the problem work exceeded a routine physical review.
  • Evaluating a Separate Injury or Condition Before Treatment:
    • A patient is seen for shoulder pain, and the provider performs a joint injection. However, the provider also performs a full evaluation and medical decision-making process for a completely different joint or systemic issue on the same day.
    • Billing: The E/M service is billed with Modifier 25 alongside the injection procedure code, backed by records showing distinct clinical reasoning for both.

Examples of Inappropriate Usage (When You CANNOT Use Modifier 25)

  • Routine Pre-Operative/Post-Operative Checks:
    • Examining a wound, checking vital signs, or getting standard consent immediately before a minor procedure. This work is already bundled into the payment for the procedure.
  • New Patient E/M Codes:
    • Appending Modifier 25 to initial/new patient visit codes (such as CPT 99202–99205). New patient codes are already evaluated independently and do not require this modifier.
  • Same Diagnosis Without Extra Cognitive Work:
    • Doing a brief look-over for the exact same symptom the procedure is meant to fix, without independent medical decision-making or a separate problem being managed.

Key Rules for Compliance

  • Documentation is mandatory: The medical record must explicitly show a distinct history, examination, and/or level of medical decision-making that stands completely on its own outside of the procedure note.
  • Different diagnoses are not strictly required, though the work must be distinct and above/beyond the standard procedure care.
