Quick Modifier 76 Summary

What is Modifier 76? Modifier 76 is a medical billing modifier appended to CPT or HCPCS codes to indicate Repeat Procedure or Service by Same Physician or Other Qualified Health Care Professional. Under official CMS and AMA coding rules, it is applied when modifier 76 indicates that a procedure or service was repeated subsequent to the original service on the same calendar day.

When to Use Modifier 76

Repeat 12-lead ECG performed 4 hours later following acute chest pain worsening (93000-76).

Clinical Example: Repeat postoperative chest X-ray after chest tube placement.

✖

When NOT to Use (Audit Pitfalls)

Do not use if the repeat test was interpreted by a different provider (use modifier 77).

Denial Risk: Appending Modifier 76 without meeting these criteria triggers post-payment claims recoupment under payer audits.

Official Coding Guidelines & NCCI PTP Unbundling

Prevents claim denial as a duplicate submission when clinical necessity requires repeating a test.

National Correct Coding Initiative (NCCI) Policy: Clears duplicate claim screening filters at the Medicare Administrative Contractor (MAC). When two procedure codes form a Column 1/Column 2 edit pair with modifier indicator 1, appending Modifier 76 signals that the criteria for distinct, separate, or unbundled service delivery have been fully met.
