Test Classification and CPT Coding

CPT Code:

87076 - Culture, bacterial; anaerobic isolate, additional methods required for definitive identification, each isolate
87077 - Culture, bacterial; aerobic isolate, additional methods required for definitive identification, each isolate
87186 - Susceptibility studies, antimicrobial agent; microdilution or agar dilution (minimum inhibitory concentration [MIC] or breakpoint), each multi-antimicrobial, per plate
87070 - Culture, bacterial; any other source except urine, blood or stool, aerobic, with isolation and presumptive identification of isolates (anaerobic culture if appropriate)

 

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.

Profile/Testing Information

Reflex Information:

  • If anaerobes are suspected, order Billings Clinic: #6728 “Culture, Biopsy/Tissue, Anaerobic Bacteria.
  • This test may automatically reflex to other tests. An additional fee may be added.
  • The ordering physician/provider must indicate if the reflex test is NOT DESIRED. Indicate on order if no reflex test is desired.
