What code do I use when my physician injects the piriformis muscle for piriformis syndrome under ultrasound guidance in the office? Do I report 64445 for the nerve injection?
CPT code 20552 and 76942 for the ultrasound guidance. Per CPT Assistant April 2012; there is a significant difference in the work and procedure, as well as intent, between an injection of the piriformis muscle and the perineural injection of the sciatic nerve. The sciatic nerve injection code (64445) should not be used to report a piriformis injection. Piriformis muscle injection(s) should be reported using CPT code 20552, Injection(s); single or multiple trigger point(s), 1 or 2 muscle(s).
