What 82642 covers

A clinical laboratory measures dihydrotestosterone (DHT) concentration, typically in serum. Clinicians may order the test when evaluating abnormal androgen effects, such as virilization, or investigating a suspected defect in the conversion of testosterone to DHT, including 5-alpha-reductase deficiency. Results are interpreted with the clinical presentation and may be considered alongside testosterone measurements.

Report 82642 for the DHT assay performed; the code represents the measurement, not a panel of androgen tests. Medicare pays it through the Clinical Laboratory Fee Schedule (CLFS), with one national amount applying in every state and locality and no office or facility difference. The 2026 national CLFS amount is $29.28, unchanged since 2020. The assay is paid only through the CLFS, not the physician fee schedule.

This summary was written with AI assistance from CMS Clinical Laboratory Fee Schedule data. Amounts on this page come directly from CMS files.

How Medicare pays 82642

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 82642. 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 82642 with status X (excluded by statute), so the test itself is paid only from the CLFS.

82626DHEA testDHEA, not DHEA-S$25.27
82626 measures DHEA, an adrenal androgen, rather than DHT. The assays address different aspects of androgen status.

82642 billing questions

When should 82642 be reported instead of a testosterone assay?

Report 82642 when the laboratory measures DHT. Testosterone assays measure a different androgen and do not substitute for the DHT result.

Is DHT part of a broader androgen panel under this code?

No. 82642 represents the DHT measurement; report other androgen assays separately when they are performed and appropriate.

How many units should be reported?

Report the assay performed under 82642. The code describes the DHT measurement, not a count of androgen analytes.

Does Medicare pay 82642 through the physician fee schedule?

No. Medicare pays this laboratory test through the CLFS, using one national amount across localities and settings.

How is physician-fee-schedule payment handled for 82642?

Medicare pays 82642 through the CLFS; the code is excluded from the physician fee schedule.
