Clinical documentation must explicitly state the injection target (piriformis or surrounding muscles versus direct sciatic nerve/perineural block) to support selection of CPT 20552 versus 64445.
If pelvic MRI CPT 72195-72197 is billed with a piriformis-region injection, documentation must include justification for the imaging, though policy indicates these codes will be denied when used for mapping prior to injection.
All documentation must be maintained in the patient's medical record and made available to the contractor upon request; every page must be legible and include patient identification (complete name and dates of service).
The medical record must include the legible signature of the physician or non-physician practitioner responsible for and providing the care.

When the injection target is the piriformis muscle or surrounding muscle groups (e.g., gemelli, obturator internus), bill CPT 20552 (injection, muscle trigger point/intramuscular).
When clinical notes document a direct perineural/sciatic nerve block, bill CPT 64445 (injection, anesthetic agent; sciatic nerve, single).
Injection of trigger points is covered only when services meet the reasonable and necessary requirements of Local Coverage Determination L33912.
Trigger point injections (CPT 20552 or 20553) are covered when medically necessary to treat documented myofascial trigger points causing pain, with procedural documentation supporting medical necessity.
CPT 20552 may be reported for trigger point injections involving 1 or 2 muscles; CPT 20553 may be reported for injections involving 3 or more muscles.
The medication used for the injection must be billed on the same claim as the trigger point administration and reported with the appropriate HCPCS drug J-code or revenue code.
