Initial TPI is covered for myofascial pain when ALL are met: a focal area of pain in skeletal muscle; clinical evidence of a trigger point, meaning muscle pain associated with at least 2 of - a hyperirritable spot, a taut band on palpation, possible referred pain; a physical exam identifying a focal hypersensitive bundle or nodule harder than normal consistency, with or without a local twitch response and referred pain; AND either failure of noninvasive conservative therapy as first-line, OR limited/blocked joint or limb movement, OR the injection is needed for diagnostic confirmation. REPEAT TPI into previously injected points requires ALL of: >= 50% relief of primary (index) pain from the most recent TPI measured on the SAME scale at baseline and post-injection; that relief lasting at least 6 WEEKS; and recurrence causing objective functional limitation with >= 50% improvement demonstrated on a functional scale. The patient must be actively participating in a documented rehabilitation, home-exercise or functional-restoration program. NOT COVERED: TPI containing biologics (PRP, stem cells, amniotic fluid) or injectates other than local anesthetic; injection into multiple muscle groups in DIFFERENT anatomical regions in one session; multiple block types (ESI, sympathetic, facet) in the same session as TPI; fluoroscopic or MRI guidance (not reasonable and necessary) and ultrasound guidance (investigational); and TPI for headache, neck or low back pain WITHOUT actual trigger points, diffuse muscle pain, chronic pain syndrome, lumbosacral canal stenosis, fibromyalgia, non-malignant multifocal musculoskeletal pain, CRPS, pelvic pain/sexual dysfunction, whiplash, neuropathic pain, or hemiplegic shoulder pain - all investigational. Routine periodic or continuous scheduling is not covered. [NEEDS CLINICAL SPOT-CHECK]
