What 82383 covers
This laboratory assay measures catecholamine concentrations in blood. Clinicians may order it when evaluating symptoms or findings that suggest excess catecholamine activity, including suspected pheochromocytoma or paraganglioma. Endocrinologists and other treating clinicians may request the test, which is performed by a clinical laboratory in a hospital or reference-laboratory setting. The blood specimen distinguishes this service from urine catecholamine testing.
Report 82383 for the blood catecholamine assay; use the code that matches the assay performed when a three-catecholamine test is ordered. Medicare pays the test through the CLFS, with one national amount and no locality, geographic, or office-versus-facility adjustment. The 2026 national CLFS amount is $29.08, unchanged since 2020. The test is paid only through the CLFS, with no physician fee schedule payment for 82383.

How Medicare pays 82383
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 82383. 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 82383 with status X (excluded by statute), so the test itself is paid only from the CLFS.

82383 billing questions
When should 82383 be used instead of 82382?

How does 82383 differ from 82384?
82383 identifies the blood catecholamine assay. 82384 identifies an assay of three catecholamines; select the code that matches the test performed.
Can blood and urine catecholamine testing be reported with the same code?
No. The specimen distinguishes these services: report 82383 for blood and 82382 for urine.
Does 82383 have a separately payable physician interpretation?
Medicare pays 82383 through the CLFS only; the physician fee schedule does not pay this test.
What should the record support for reporting 82383?
The documentation should support that the ordered and performed assay measured catecholamines in a blood specimen.
