There is no national rate. HCPCS G0327 is listed under the Clinical Laboratory Fee Schedule, but the Q4 2026 CLFS file lists it as MAC-priced: each Medicare Administrative Contractor sets its own amount, typically for new or proprietary tests awaiting national pricing. Treat the blank amount as unpriced, not as $0.

The Medicare lab fee for G0327 Copy link

Priced under the Clinical Laboratory Fee Schedule, not the Physician Fee Schedule

G0327 carries status X on the Physician Fee Schedule because Medicare pays for clinical lab tests under a separate fee schedule, the CLFS. For this code the CLFS publishes no national amount—each Medicare Administrative Contractor (MAC) prices it, typically a new or proprietary test awaiting national pricing.

MAC-priced—no national CLFS rate

The Q4 2026 CLFS file lists G0327 with pricing indicator L: your Medicare contractor sets the amount. The file's zero-dollar placeholder is not a price—treat this code as unpriced nationally, not free.

Why would a Medicare claim for G0327 be denied or paid less?

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

  • Its status indicator is X (statutory exclusion)—The statutory definition of physician services does not include this item. Medicare prices this code under the Clinical Laboratory Fee Schedule instead; the CLFS rate is shown on this page. See CLFS rate
  • 11 codes form NCCI pairs with G0327 carrying modifier indicator 0—no NCCI-associated modifier bypasses the edit, so billed together on the same date of service, a line of the pair denies. See billing together
  • 308 codes pair with G0327 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 1 unit per patient per date of service exceeds G0327'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.

Modifier 59 and the X modifiers are not a universal bypass—CMS expects the most specific applicable modifier, and which one that is depends on the pair and the documented circumstances.

Source & method

Show sources

The lab amount comes from the Clinical Laboratory Fee Schedule record shown above. Its release and effective date are independent of the PFS release used for status evidence. 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.
