trigger point inj

When a doctor does trigger point inj's x30 how would that be coded, (neck,back,lat epidond)

re: trigger point inj

TPI's are per session codes and not per injection codes, no modifiers can be used. Select the appropriate code by the no. of muscles injected. For example: If a patient presents with pain in abdominal area and physician injects 6 injections on patient's Transverse Abdominus and 4 injections on patients Rectus Abdominus, you would report CPT® 20552 [Injection(s);single or multiple trigger point(s), 1 or 2 muscle(s)]. Unit of 1. If 3 or more muscles injected, unit of 1, code 20553. You would bill one time only per session for one or more injections depending on the number of muscle(s) involved. Example of diagnosis code 729.1 (Myalgia and myositis, unspecified).
