What 84580 covers
This assay measures the amount of urobilinogen in a timed urine collection. Urobilinogen is formed during bilirubin metabolism, and urine measurement may be part of laboratory evaluation of hepatic or hemolytic disorders. A clinical laboratory reports the quantitative result when the ordered test uses a timed urine specimen.
Report 84580 for quantitative timed urine measurement; use 84578 for qualitative urine testing and 84583 for quantitative urine testing on a non-timed specimen. Match the code to the test and collection performed. Medicare pays 84580 only through the CLFS, at one national amount across localities with no office-versus-facility payment difference. The 2026 national CLFS amount is $9.55, unchanged from 2020 through 2026. The test is excluded from the physician fee schedule and paid only under the CLFS.
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 84580
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 84580. 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 84580 with status X (excluded by statute), so the test itself is paid only from the CLFS.
