Why would a Medicare claim for 77387 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.

Why a 77387 line may not pay separately Copy link

CMS publishes no separately payable amount for 77387 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 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.

Codes to compare

National Q3 2019 amounts at GPCI 1.000. A blank means this schedule does not publish a payable PFS amount.

Billing policy Copy link

These billing-policy indicators explain how 77387 is treated. They apply whether the code is nationally priced or carrier-priced: a restriction like "bilateral not allowed" still matters on a carrier-priced code.

Policy Value What it means
Bilateral surgery 0 No bilateral adjustment. The 150% bilateral payment adjustment does not apply to this procedure.
Assistant at surgery 0 Restricted without documentation. Payment for an assistant at surgery is restricted for this procedure unless supporting documentation establishes medical necessity.
Co-surgeons 0 Not permitted. Medicare does not recognize co-surgeons (modifier 62) for this procedure.
Team surgery 0 Not permitted. Medicare does not recognize a surgical team (modifier 66) for this procedure.
Multiple procedures 0 No reduction. No multiple-procedure reduction applies when this procedure is billed with others on the same date; each is paid at its full fee schedule amount.
Professional/technical split 0 No PC/TC split. This is a physician service code; the professional/technical split does not apply, and the code is billed as a single service.

Source & method

Show sources

This page uses CMS's Medicare Physician Fee Schedule Q3 2019 release (effective July 2019). 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.
