What 82670 covers
This laboratory assay measures total estradiol, an estrogen hormone. It is commonly ordered in the evaluation of menstrual irregularity, amenorrhea, infertility, ovarian function, and pubertal development, and to monitor ovarian stimulation during fertility treatment. Obstetrician-gynecologists, reproductive endocrinologists, and other clinicians may order it. Serum is a typical specimen.
Report 82670 for the total estradiol assay performed; it is distinct from assays for other estrogens or for free estradiol. Medicare pays the test under the Clinical Laboratory Fee Schedule (CLFS), not the physician fee schedule. The 2026 national CLFS amount is $27.94, unchanged from 2020 through 2025. The same amount applies across states and localities, with no office-versus-facility difference.

How Medicare pays 82670
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 82670. 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 82670 with status X (excluded by statute), so the test itself is paid only from the CLFS.
