What 84244 covers
Renin testing measures the kidney enzyme involved in regulating blood pressure and fluid balance. A clinical laboratory generally performs the test on a plasma specimen. Clinicians may order it during evaluation of hypertension, including suspected primary aldosteronism or other causes of abnormal blood pressure. Renin is commonly interpreted alongside aldosterone, and collection conditions and medications can affect results.

How Medicare pays 84244
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 84244. 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 84244 with status X (excluded by statute), so the test itself is paid only from the CLFS.

84244 billing questions
When is a renin assay ordered?
It is used in evaluating hypertension, suspected primary aldosteronism, and other causes of abnormal blood pressure or potassium. Results are commonly considered with aldosterone testing.
How does renin testing differ from aldosterone testing?
Renin measures a kidney enzyme involved in blood pressure regulation; aldosterone measures a hormone. They are distinct tests and may be ordered together for an aldosterone-related evaluation.
What specimen is used?
Renin testing is generally performed on plasma. Collection conditions and medications can affect interpretation, so relevant clinical context should accompany the result.
How does Medicare pay for 84244?
Medicare pays the test through the CLFS, with one national amount across localities and settings. It has no separate physician fee schedule payment.
Can aldosterone be reported separately?
Yes. Aldosterone is a distinct test from renin and may be ordered with it for an aldosterone-related evaluation.
