CPT 99377

No national payment amount

Status B is not separately payable under the PFS.

Does Medicare pay separately for CPT 99377 in 2026?

Not at a published national rate. CPT 99377 carries status B (bundled) in the Q3 2026 release. Medicare folds payment for this code into the service it is incident to, never onto its own line. Treat the blank amount as unpriced, not as $0.

Common questions

Why is there no payment amount for 99377?

Its status indicator is B (bundled). Medicare folds payment for this code into the service it is incident to, never onto its own line. The blank is deliberate: the amount is either unknown or paid under another provision, so reading it as $0 would be wrong.

Why would a Medicare claim for 99377 be denied or paid less?

Each item below comes from a CMS indicator on this page — not general billing advice.

  • Its status indicator is B (bundled) — Medicare folds payment for this code into the service it is incident to, never onto its own line. See status indicators
  • 92 codes can never be billed with 99377 on the same date of service — NCCI denies those pairs even with a modifier. See billing together
  • 5789 codes pair with 99377 only when modifier 59 (or XE, XS, XP, XU) documents a distinct service — billed together without one, a line of the pair denies. See billing together

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.

When does this rate change?

CMS publishes a fee schedule release every quarter (January, April, July, October), and each is versioned here. See what changed each release, or get an email when a new release moves rates.

Computation & policy

How this amount is computed

amount = (work RVU × work GPCI + PE RVU × PE GPCI + MP RVU × MP GPCI) × conversion factor. National amounts use GPCI = 1.000. To price an RVU figure of your own, use the RVU-to-dollars converter.

Release Q3 2026

Every rate combines three parts: work (the clinician’s time, skill and effort), practice expense (office overhead — higher when the service is done in a doctor’s own office), and malpractice (the share of liability-insurance cost). A blank means CMS publishes no national number for that part. Read it as unknown, and never as zero.

Source & method

This is computed from CMS's Medicare Physician Fee Schedule Q3 2026 release (schedule pfs, effective July 2026). National amounts apply a GPCI of 1.000 and leave sequestration off. The status indicator decides payability, never the RVU values, so a blank RVU stays blank. Releases are immutable: a rate retrieved for a past quarter always reflects that release. Commercial and cash-pay figures anywhere on this page are arithmetic on the Medicare amount, using commonly cited reimbursement ranges. They're illustrative, and no nationwide claims database stands behind them.

Conversion factor $33.4009 read from the same file, row 11, column 26.
