What 86906 covers
Complete serologic Rh phenotyping tests a patient’s red cells for Rh-system antigens, extending beyond a single Rh(D) result. Transfusion-service laboratories perform it during red-cell antibody investigations and when antigen matching is needed, including for patients with alloantibodies or ongoing transfusion needs. Results help characterize the patient’s Rh antigens so the blood bank can select compatible red-cell units.
Report 86906 for the complete Rh phenotype, rather than as a count of separately identified antigens. Medicare pays the test only through the CLFS; the 2026 national amount is $7.75, unchanged since 2020. The same amount applies across states and localities, with no geographic or office/facility adjustment. The physician fee schedule does not pay this service.
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 86906
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 86906. 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 86906 with status X (excluded by statute), so the test itself is paid only from the CLFS.

86906 billing questions
How does 86906 differ from Rh(D) typing?
86906 reports a complete serologic Rh phenotype. Code 86901 is for Rh(D) typing alone.
Does 86906 include ABO typing?
No. ABO typing is a separate service reported with 86900 when performed.
Does each Rh antigen count as a unit?
No. This code represents the complete Rh phenotype, not a separate count for each antigen identified.
When is complete Rh phenotyping ordered?
It is used in transfusion-service workups, including when a patient has red-cell alloantibodies or needs antigen matching for transfusion support.
What should the record support?
Document the complete Rh phenotyping performed, the result, and the clinical context, such as an antibody workup or need for antigen-matched red cells.
How does Medicare pay for 86906?
Medicare pays it through the CLFS at one national amount across localities, without an office or facility adjustment.
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.
