HCPCS J1644 has no published national rate. It carries status E (excluded) in the Q4 2026 release. A regulation removes this code from the fee schedule. When covered, it is paid under reasonable charge procedures instead. The blank amount means unpriced, not $0.

Why would a Medicare claim for J1644 be denied or paid less?

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

  • Its status indicator is E (excluded)—A regulation removes this code from the fee schedule. When covered, it is paid under reasonable charge procedures instead. See status indicators
  • 299 codes pair with J1644 under modifier indicator 1—separately payable only when an NCCI-associated modifier (59, or a more specific XE, XS, XP, or XU) is clinically appropriate and the documentation supports a distinct service; without one, a line of the pair denies. See billing together
  • More than 40 units per patient per date of service exceeds J1644's Medically Unlikely Edit (MUE) limit. 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.

Source & method

Show sources

This page uses CMS's Medicare Physician Fee Schedule Q4 2026 release (effective October 2026). 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. CMS owns the code description shown for HCPCS Level II codes. Our methodology explains sourcing, parsing, versioning, and how we cross-check claims before we publish them.
