Test Classification and CPT Coding

CPT Code:

87077 - definitive identification, aerobic; each isolate
87186 - MIC; each isolate
87070 - isolation and presumptive identification of isolates

Microbiology Coding:
Proper coding for MICROBIOLOGY tests depends on what procedures are actually performed which may depend on the organism(s) isolated. When a culture is initially set up, organism(s) may be isolated and a presumptive identification takes place. When/if an organism(s) grows, a definitive identification and possible MIC of each organism may be indicated.
