Test Code5202
CPT Codes
87116, 87206
Includes
Mycobacteria Culture, Concentration, Acid-Fast Bacilli Stain
An additional charge for Concentration (CPT code(s): 87015) will be added as appropriate.

CPT code(s) 87118: Matrix Assisted Laser Desorption/Ionization-Time of Flight or
CPT code(s) 87153: AFB Sequencing
If TB is isolated for the first time or after three months after the first isolate from a patient, susceptibilities will be performed at an additional charge (CPT code(s): 87190 per drug.

Clinical Significance
There are more than 70 species of mycobacteria of which the primary pathogen is M. tuberculosis. Tuberculosis is a chronic, granulomatous disease caused by M. tuberculosis. Identification, and, if appropriate, antibiotic sensitivity, is required to initiate necessary therapy.
