Report a problem

CPT 99359 has no published national rate. It carries status I (not valid) in the Q4 2023 release. Medicare uses a different code to report and pay for this service. The blank amount means unpriced, not $0.

Why is there no national PFS amount for 99359?

Its status indicator is I (not valid). Medicare uses a different code to report and pay for this service. Status I is not separately payable under the PFS.

CMS indicators that apply to 99359: GLOB DAYS ZZZ (add-on code).

Global surgery period

Add-on code

GLOB DAYS

ZZZ

This code is always billed alongside another service and carries no follow-up period of its own. The primary procedure's global period governs; this indicator does not determine whether either line is payable.

Why would a Medicare claim for 99359 be denied or paid less?

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

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 (4)

CMS publishes no separately payable amount for 99359 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.
  • 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.
  • Check for documentation on file before appealing an assistant-at-surgery denial: payment on the -80 or -AS line is restricted for this procedure unless medical necessity is established.
  • 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.
