CPT® Code 20553: Injection(s); Single or Multiple Trigger Point(s), Three or More Muscles

CPT® code 20553 is used to report trigger point injections administered into three or more muscles for the treatment of myofascial pain, muscle spasms, or other soft tissue dysfunctions. This procedure is commonly performed in outpatient settings by pain management specialists, physical medicine physicians, chiropractors, and integrative care providers.

What is CPT Code 20553?

CPT 20553 describes the injection of anesthetic and/or corticosteroid agents into trigger points located in three or more muscles. A trigger point is a tight, hyperirritable area within skeletal muscle that can cause localized or referred pain.

This service involves:

• Palpation and identification of active trigger points in multiple muscle groups
• Sterile preparation of the injection site(s)
• Insertion of a fine needle into the muscle belly
• Injection of medication to reduce inflammation and interrupt the pain cycle

Trigger point injections are typically used to treat myofascial pain syndrome, chronic tension headaches, fibromyalgia, and postural or repetitive strain injuries.

When to Use CPT Code 20553

Report CPT 20553 when three or more muscles are treated during a single session, regardless of how many individual trigger points are injected within those muscles.

Use CPT:

• For patients presenting with widespread muscle pain or tightness
• When prior conservative treatment (e.g., stretching, heat, NSAIDs) has not provided relief
• As part of a multimodal approach to chronic musculoskeletal pain

Documentation should include:

• The muscle groups injected
• The medications and dosages used
• The number of trigger points addressed in each muscle
• The patient’s diagnosis and medical necessity for the injections

Coding Considerations

• For injections in only one or two muscles, report CPT 20552 instead.
• If the procedure is performed on the same day as an E/M visit, and both are medically necessary, append modifier -25 to the E/M code.
• Common ICD-10 diagnoses that support CPT 20553 include M79.1 (Myalgia), M54.5 (Low back pain), and M79.7 (Fibromyalgia).

CPT 20553 and Pain Management

Trigger point injections under CPT 20553 are often part of an ongoing pain management or rehabilitation plan. Payers typically require evidence of conservative therapy failure, as well as documentation of progressive or refractory symptoms. Medical necessity must be clearly linked to functional impairment and the patient’s response to prior treatments.

Objective tracking of symptom improvement, pain scales, and functional scores can further support continued treatment.
