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.

Why a 99418 line may not pay separately Copy link

CMS publishes no separately payable amount for 99418 in this release, so reconciling the line means establishing which status governed the date of service rather than chasing a fee-schedule difference.

What to check

  • 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.
  • Check the place of service: CMS publishes no Office (non-facility) practice-expense amount for this code, so it prices in a Facility setting only.
  • Reconcile this line together with the primary procedure on the same claim—it is an add-on that is never billed alone and carries no global period of its own.
  • 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.

Source & method

Show sources

This page uses CMS's Medicare Physician Fee Schedule Q1 2023 release (effective January 2023). National baselines use GPCI 1.000 and exclude sequestration. Whether a national amount exists depends on the status and CMS’s payment instructions; blank RVUs are never treated as zero. Past releases are never edited, so these sources stay valid after CMS publishes a newer one. Our methodology explains sourcing, parsing, versioning, and how we cross-check claims before we publish them.
