Modifier 76: Repeat Procedure, Same Physician, Same Day

Definition

Modifier 76 is used when a physician repeats the exact same procedure on the same patient by the same physician on the same day. The repeat procedure must be medically necessary due to failed first attempt, inadequate results, or patient safety. Modifier 76 indicates the procedure is a clinically justified repeat, not an error or duplicate billing.

When to Use

  1. Injection misses target; physician re-injects same joint (20610 first attempt, 20610-76 second attempt on same knee)
  2. EKG tracing unreadable; physician repeats test same day (93000 first, 93000-76 second)
  3. Skin biopsy specimen insufficient for pathology; repeat biopsy same area (11100 first, 11100-76 second)
  4. Urinalysis contaminated; lab repeats specimen collection and analysis same day (81002 first, 81002-76 second)

Documentation Requirements

Document reason for repeat in chart. State why first attempt was unsuccessful. For injections, note if first attempt missed anatomical target or inadequate anesthesia achieved. For diagnostics, explain specimen inadequacy or technical failure. Time between first and repeat should be brief (same session or within hours). Do not use modifier 76 for planned procedures or procedures on different body sites.

FAQ

Can I use modifier 76 if the first attempt was by a different physician?

No. Use modifier 77 if a different physician performs the repeat. Modifier 76 is same physician only.

What if the repeat procedure is on a different body site?

Do not use modifier 76. Use a separate code for the different site, or use modifier 59 if same procedure code.

How much time can pass between first and repeat attempt?

Modifier 76 implies same session or same day. If repeat is days or weeks later, do not use 76.
