The national CLFS allowed amount is $6.61 for CPT 83930 under the Clinical Laboratory Fee Schedule (CLFS)—a single national rate, the same in every locality, before the ~2% sequestration cut. On the Physician Fee Schedule CPT 83930 carries status X (statutory exclusion) because lab services are paid under the CLFS instead. Figure from the Q3 2026 CLFS file, effective January 1, 2026.

The Medicare lab fee for 83930 Copy link

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

83930 carries status X on the Physician Fee Schedule because Medicare pays for clinical lab tests under a separate fee schedule, the CLFS. Since 2018 the CLFS rate is a single national amount—the same in every state and setting, with no locality adjustment.

Original Medicare generally pays 100% of the CLFS amount for covered clinical diagnostic lab tests—no Part B coinsurance or deductible, unlike most physician services.

Billing together (NCCI edits) Copy link

NCCI Q3 2026

Based on CMS's National Correct Coding Initiative (NCCI). A few examples appear here; use the complete edit page to check a specific pair.

Not separately payable with 83930 on the same date of service—no modifier bypasses the edit (modifier indicator 0)

96523 96523 denies

Separately payable with 83930 only when an NCCI-associated modifier is appropriate and documented (modifier indicator 1)

83861 83930 denies

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.

Common payment questions Copy link

Why would a Medicare claim for 83930 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
  • 1 code forms an NCCI pair with 83930 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
  • 1 code pairs with 83930 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

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.
