What 84207 covers
Code 84207 identifies a laboratory assay that measures pyridoxal phosphate, the vitamin B-6 analyte. The result is reported as a vitamin B-6 level. It is distinct from assays for vitamin B-2, vitamin B-12, and vitamin D, which measure different analytes and use different codes. Report this code for the vitamin B-6 assay rather than substituting another vitamin assay code. The assay is a laboratory service, not a panel code.
Medicare pays 84207 through the Clinical Laboratory Fee Schedule (CLFS) at a single national rate. The 2026 national amount is $28.10 and has remained unchanged since 2020. The same amount applies across states and localities, with no geographic or office-versus-facility adjustment. The CLFS assigns one nationally applicable amount to the code. The test is paid only through the CLFS and has no separate physician fee schedule payment.

How Medicare pays 84207
Clinical lab tests aren’t priced like physician services. They’re paid from their own fee schedule, with its own rules. See the whole lab fee schedule.
One national amount
CMS sets a single Clinical Laboratory Fee Schedule amount for 84207. There’s no geographic (GPCI) adjustment, so it pays the same in every state and payment locality.
No office or facility rate
Lab tests aren’t built from relative value units, so there’s no office and facility split: the place of service doesn’t change the CLFS amount.
Updated every quarter
CMS republishes the CLFS each quarter. New tests, often proprietary laboratory analyses (PLA codes), join during the year; existing amounts are updated each January.
Excluded from the physician fee schedule
The physician fee schedule lists 84207 with status X (excluded by statute), so the test itself is paid only from the CLFS.
