What 87107 covers
This service identifies a mold definitively after it has been recovered in culture. Clinical microbiology laboratories report it when a cultured mold needs identification as part of evaluating a suspected fungal infection. The code is specific to mold; yeast identification is reported separately under a different code.
Report the service for each mold organism definitively identified. Medicare pays it only under the Clinical Laboratory Fee Schedule (CLFS), with one national amount across states and localities and no office-versus-facility payment difference. The 2026 national CLFS amount is $10.32, unchanged since 2020. Medicare pays this test only through the CLFS, not as a physician fee schedule service.
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 87107
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 87107. 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 87107 with status X (excluded by statute), so the test itself is paid only from the CLFS.
