Mycobacteria, Culture, Identification, and TB Susceptibility
Test Code14049
CPT Codes
87116
Includes
An additional charge for Concentration (CPT code(s): 87015) will be added as appropriate.
Identification will be performed at an additional charge for each organism:
CPT code(s) 87118: Matrix Assisted Laser Desorption/Ionization-Time of Flight
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).
If other Mycobacteria species are isolated, appropriate susceptibilities can be performed at an additional charge if requested (CPT code(s): 87186 per organism).
