What 82384 covers
This assay measures levels of three catecholamines as fractionated laboratory results. Clinicians may order it when evaluating suspected catecholamine excess, including possible pheochromocytoma. A clinical laboratory performs the assay and reports results for the ordering clinician. Code 82384 identifies fractionated testing of three catecholamines; codes 82382 and 82383 instead identify urine and blood catecholamine assays, respectively, so select the code that describes the assay performed.
Report the laboratory assay under 82384 rather than billing each catecholamine fraction as a separate service. Medicare pays it only through the CLFS, at one national amount across states and localities, with no geographic or office-versus-facility adjustment. The 2026 national CLFS amount is $25.25, unchanged since 2020. The test is excluded from the physician fee schedule by statute.

How Medicare pays 82384
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 82384. 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 82384 with status X (excluded by statute), so the test itself is paid only from the CLFS.

Does 82384 apply to every catecholamine test?
Use 82384 for the fractionated assay of three catecholamines. Codes 82382 and 82383 identify urine and blood catecholamine assays.
How does Medicare pay for 82384?
Medicare pays 82384 through the CLFS using one national amount across states and localities, with no office-versus-facility adjustment.
What should the documentation identify?
