What 87106 covers
CPT 87106 represents definitive identification of a yeast organism recovered through fungal culture. It describes the identification work, not the culture or isolation step itself. The code applies to yeast; mold identification is reported under 87107. Report the service for each organism identified, rather than counting specimens as units. When a culture yields an organism identified as yeast, this code represents that identification service. It distinguishes yeast identification from fungal culture and from identification of mold.
Medicare pays 87106 from the CLFS at one national amount that applies across states and localities, without an office-versus-facility payment difference. The 2026 national CLFS amount is $10.32, unchanged from 2020 through 2026. The test is paid only through the CLFS. Reported service counts follow organisms identified, not the number of submitted specimens.

How Medicare pays 87106
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 87106. 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 87106 with status X (excluded by statute), so the test itself is paid only from the CLFS.
