What 82671 covers
Code 82671 identifies a laboratory analysis that measures estrogen in fractions. It is distinct from assays directed at a single named estrogen, such as estradiol, estriol, or estrone. The result is used in the context of the clinical question and other findings. Clinical laboratories perform and report the assay.
Report 82671 when the service performed is fractionated estrogen analysis. When testing is limited to a named estrogen, select the code that describes that assay. Medicare pays the test through the CLFS at one national amount across localities, with no office or facility payment difference. The 2026 national CLFS amount is $32.30, unchanged from 2020 through 2026. The test is paid only from the CLFS and is excluded from the physician fee schedule.

How Medicare pays 82671
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 82671. 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 82671 with status X (excluded by statute), so the test itself is paid only from the CLFS.
