What 86622 covers
This serologic test analyzes a patient specimen for antibodies to Brucella bacteria. It may be ordered when clinical findings and exposure history raise concern for brucellosis, including after contact with infected livestock or consumption of unpasteurized dairy products. Serum is commonly used. The code identifies the Brucella antibody target, not a particular assay method or antibody class.
Report 86622 for the Brucella antibody analysis performed. Medicare pays the test through the CLFS at one national amount, with no locality or office-versus-facility adjustment. The 2026 national CLFS amount is $8.93, unchanged since 2020. Medicare pays the test only through the CLFS; it is excluded from the physician fee schedule.

How Medicare pays 86622
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 86622. 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 86622 with status X (excluded by statute), so the test itself is paid only from the CLFS.

What specimen is commonly used for Brucella antibody testing?
Serum is commonly used for this serologic testing.
How does Medicare pay for 86622?
Medicare pays 86622 through the CLFS at one national amount. The amount is the same across localities and does not vary between office and facility settings.
