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
87205 - Smear, primary source with interpretation; Gram or Giemsa
stain for bacteria, fungi, or cell types
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
Includes Gram stain
Reflex Information:
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.
