What 82088 covers
The assay measures aldosterone, an adrenal hormone involved in regulating sodium, potassium, and blood pressure. It is commonly performed on a blood specimen. Clinicians may order it when evaluating resistant or otherwise concerning hypertension, low potassium, or suspected adrenal hormone disorders. Endocrinology, primary care, and hypertension practices may request it as part of an adrenal or renin-aldosterone evaluation.
Report 82088 for the aldosterone assay itself; it is not a combined renin-and-aldosterone panel. When ordered together, renin is reported separately. Medicare pays this laboratory test through the CLFS, with one national amount applying across localities and care settings and no office or facility difference. The 2026 national CLFS amount is $40.75, unchanged since 2020. The test is paid only through the CLFS, rather than the physician fee schedule.

How Medicare pays 82088
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 82088. 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 82088 with status X (excluded by statute), so the test itself is paid only from the CLFS.

82088 billing questions
When should 82088 be selected instead of a renin assay?
Use 82088 for the aldosterone measurement. Renin is a distinct analyte and is reported separately when ordered.
Does 82088 include renin testing?
No. Aldosterone and renin are separate assays, even when ordered together to evaluate a renin-aldosterone pattern.
What specimen is used for the aldosterone assay?
The assay is performed on a blood specimen.
How should aldosterone and renin be reported when both are ordered?
Report the aldosterone assay with 82088 and report the renin assay separately.
Does Medicare pay 82088 under the physician fee schedule?
No. Medicare pays 82088 through the CLFS, using the same national amount across localities and care settings.
