What 84144 covers
This assay measures progesterone, a reproductive steroid hormone, in a serum specimen. Clinicians may order it during infertility and ovulation evaluations, including to assess whether ovulation has occurred, or as part of selected menstrual and pregnancy evaluations. Fertility specialists, obstetrician-gynecologists, and other clinicians interpret the result alongside cycle timing, clinical history, and other laboratory findings. A clinical laboratory performs the assay and reports the measured progesterone concentration.
Report 84144 for the progesterone assay; it measures a different analyte from pregnanediol, pregnenolone, and prolactin. Medicare pays this laboratory test through the CLFS. The 2026 national CLFS amount is $20.86, unchanged from 2020 through 2025. The same national amount applies across states and localities, with no geographic adjustment or office-versus-facility difference. Medicare pays 84144 only through the CLFS.

How Medicare pays 84144
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 84144. 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 84144 with status X (excluded by statute), so the test itself is paid only from the CLFS.
