Modifier 76: Repeat procedure or service by same physician
When it is appropriate
Append modifier 76 when the same physician repeats the same procedure or service on the same patient on the same day, for example a second chest x-ray after an intervention, to show it is a legitimate repeat rather than a duplicate line.
When it is not appropriate
Do not use 76 when a different physician performed the repeat procedure (use 77 instead), or when the second unit reflects a billing error rather than a genuinely repeated service.
CMS preference
76 does not bypass an NCCI PTP edit; it addresses duplicate claim logic for a repeated identical procedure by the same provider, so use it alongside, not instead of, any PTP-associated modifier the situation also requires.
