What 83785 covers
83785 identifies a laboratory assay that measures manganese concentration in a patient specimen. It is specific to manganese, unlike the magnesium assay 83735 and the qualitative or quantitative mass-spectrometry service 83789. Clinical laboratories perform and report this assay. In 2024, Medicare recorded 8,187 office services for 83785 and no facility services.
Report 83785 for the manganese assay performed. Medicare pays the test only through the Clinical Laboratory Fee Schedule (CLFS). The 2026 national CLFS amount is $26.65, unchanged since 2020. This national amount applies in every state and locality, with no geographic adjustment or office/facility payment difference. The test is excluded from the physician fee schedule and paid only from the CLFS, not as a physician fee schedule service.

How Medicare pays 83785
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 83785. 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 83785 with status X (excluded by statute), so the test itself is paid only from the CLFS.
