Why would a Medicare claim for 77066 be denied or paid less?

These come from CMS indicators on this page, not general billing advice.

  • Its status indicator is I (not valid)—Medicare uses a different code to report and pay for this service. See status indicators
  • 77066 splits into a professional component (modifier 26) and a technical component (modifier TC)—a claim for only one part needs that modifier to price correctly. See billing policy

Payer-specific coverage and documentation rules live outside these files, so a claim that clears every check here can still be denied on other grounds.

What to check (3)

CMS publishes no separately payable amount for 77066 in this release, so reconciling the line means establishing which status governed the date of service rather than chasing a fee-schedule difference.

  • Confirm the status that governed the date of service before working this line as a short payment—CMS publishes no separately payable fee-schedule amount for it in this release.
  • Confirm which component the line carried before comparing anything: the same code prices three ways—globally, as a professional component with modifier 26, and as a technical component with modifier TC.
  • Reprice the line against the release, locality, setting, modifier and participation status that applied to the date of service before treating any difference as an underpayment.
