Test Details
If the organism cannot be identified by the original method, then additional charges will be added for each organism: (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, then susceptibilities will be performed at an additional charge (CPT code(s): 87190 per drug).
