Culture, Fungus and Smear [4553X]
Test Code870
CPT Codes
87102, 87206
Includes
Fungal smear and culture
If culture is positive, then identification will be performed at an additional charge (CPT code(s):
87106, 87107, 87140, 87143, 87149 or 87158).
If the organism cannot be identified by the original method or if there are multiple organisms,
identification by DNA sequencing may be performed at an additional charge (CPT code(s): (CPT
code(s): 87153).
If culture is positive, then identification will be performed at an additional charge (CPT code(s):
87106, 87107, 87140, 87143, 87149 or 87158).
If the organism cannot be identified by the original method or if there are multiple organisms,
identification by DNA sequencing may be performed at an additional charge (CPT code(s): (CPT
code(s): 87153).

Clinical Significance
The prompt detection of fungus in clinical samples is extremely important for in-patient management. Disseminated fungal infections are increasing in prevalence, and fungus cultures are essential for the isolation and subsequent identification of the causative agents.
