Response to Comments: Trigger Point Injections (TPI)

This document is a response to public comments on Trigger Point Injections and cites literature on use of TPIs for myofascial pain syndrome, cervicogenic headache, and chronic non-malignant musculoskeletal pain, including ultrasound-guided interfascial blocks. The response does not itself define explicit coverage criteria, exclusions, documentation requirements, or frequency limits; manual review of the associated LCD/NCD is required to determine formal Medicare coverage policy.

"Trigger point injections (TPI) are discussed in the context of treating myofascial pain syndrome or myofascial trigger points."
