What 83498 covers
This assay measures 17-hydroxyprogesterone, an adrenal steroid hormone, generally in serum. Endocrinologists, pediatricians, and other clinicians may order it when evaluating suspected congenital adrenal hyperplasia, including follow-up of an abnormal newborn screen. It may also be part of an evaluation for androgen-related findings such as hirsutism, irregular menstruation, or early signs of androgen excess.
Report 83498 for the laboratory measurement of 17-hydroxyprogesterone; it represents one analyte rather than a panel. Medicare pays the test only through the CLFS, using one national amount in every state and locality, without an office-versus-facility payment difference. The 2026 national amount is $27.17 and has remained unchanged from 2020 through 2026. The code is excluded from the physician fee schedule, so its Medicare payment comes from the CLFS.

How Medicare pays 83498
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 83498. 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 83498 with status X (excluded by statute), so the test itself is paid only from the CLFS.
