What 87484 covers
This molecular assay detects Ehrlichia chaffeensis nucleic acid using amplification and probe detection. It is specific to this organism, not a general tick-borne disease panel or testing for Anaplasma, Babesia, or Borrelia. Select this code when the performed assay detects E. chaffeensis.
Medicare pays the test through the CLFS at one national amount, with no geographic adjustment or office-versus-facility difference. The 2026 national CLFS amount is $35.09, unchanged from 2023 through 2025. The test is excluded from the physician fee schedule by statute and is paid only through the CLFS.
This summary was written with AI assistance from CMS Clinical Laboratory Fee Schedule data. Amounts on this page come directly from CMS files.
How Medicare pays 87484
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 87484. 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 87484 with status X (excluded by statute), so the test itself is paid only from the CLFS.

87484 billing questions
When should this code be chosen instead of the Anaplasma test?
Use this code when the assay detects Ehrlichia chaffeensis. Code 87468 identifies Anaplasma phagocytophilum, a different organism.
Does this code represent a panel of tick-borne tests?
No. It represents detection of E. chaffeensis, not testing for multiple tick-borne organisms.
How does Medicare pay for this test?
Medicare pays it through the CLFS at one national amount across localities, with no office-versus-facility difference.
Is a physician interpretation separately paid under this code?
No. This test is paid only through the CLFS and is excluded from the physician fee schedule.
Where this amount comes from
FeeBase reads lab amounts directly from the CMS Clinical Laboratory Fee Schedule file for the quarter: one row per code, with its payment indicator and national amount. Contractor-priced tests are labeled, never given a made-up amount. Amounts are Medicare payment limits, not a patient’s bill or a commercial rate.
