DESCRIPTIONTrigger points are small, definite (confined to a limited space) abnormally sensitive areas in muscles, ligaments, joint capsules, tendons and related tissues that have a specific and typical area of referred pain. The trigger point is so called because its stimulation reproduces the pain complained of. Any kind of local injury to myofascial structures can induce trigger points. Other causes of trigger points are inflammation (myositis bursitis, fibrositis, arthritis, tendonitis, etc.) connective tissue disease and chronic infection.
Anesthetization of trigger points (also called myofascial or paravertebral muscle injections) relieves spasms and diminishes pain associated with myofascial pain (fibromyalgia, fibromyositis, myofascitis). Injections should generally be used with physical therapy so that the patient can take advantage of the pain relief from the injections and increase activity tolerance.
POLICYTrigger point injection of abnormally sensitive areas in muscles, ligaments, joint capsules, tendons and related tissues may be considered medically necessary to relieve spasm and diminish myofascial pain.
One reimbursement will be made per site, per session, regardless of the number of trigger point injections.
Separate billing for the drug injected is not allowed. This is included in the administration of the injection.
Reimbursement for injections of tendon sheath, ligament, trigger points or ganglion cyst (CPT 20550) will be made up to a maximum of ten (10) sessions in a three (3) month period. Reimbursement for arthrocentesis, aspiration and/or injection of small and intermediate joints (CPT 20600 and 20605) will not exceed two (2) injections per joint within thirty (30) days. Reimbursement for arthrocentesis, aspiration and/or injection of major joint or bursa (e.g., shoulder, hip, knee joint, subacromial bursa), CPT 20610, will not exceed four (4) services per site within a thirty (30) day period.
