Coverage Criteria for Trigger Point Injections

Initial diagnosis/stabilization (covered)

Covered when ALL of the following are met:

Initial diagnostic/stabilization injections: 1) Diagnosis of myofascial trigger point(s) identified by palpation; 2) Myofascial pain persisting >3 months causing tenderness and/or weakness, restricting motion and/or causing referred pain when compressed; 3) The member has failed ≥3 weeks of conventional multidisciplinary medical therapy including: a) NSAID unless contraindicated or not tolerated; b) chiropractic, physical therapy, or a prescribed home exercise program (or documented inability to tolerate such therapy); and c) activity modification; 4) Trigger points are located in a few discrete areas and are not associated with widespread muscle tenderness (e.g., fibromyalgia); 5) Injections are intended to facilitate mobilization and are not used as the sole method of treatment; 6) Up to two sets of injections at least 7 days apart may be given for diagnosis/stabilization for the same trigger; when a given body region is injected it is considered one injection service regardless of number of injections.

Additional therapeutic injections (covered with criteria)

Additional trigger injections (up to four) are medically necessary when ALL of the following are met:

Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement. The result is faster insight, stronger negotiating positions, and more informed financial decisions.

1) Prior injections resulted in ≥50% pain relief with functional improvement for ≥6 weeks; 2) There was a return of symptoms and/or deterioration following ≥6 weeks of improvement; 3) Injections are given at least two months apart for up to 12 months from the initial injection (policy references a maximum of six total sessions/earlier wording changed to four additional injections in revision history).

Not supported / experimental indications

Current evidence does not support the following:

Unsupported modalities: Dry needling (needle stimulation without injectate), trigger injection with saline or glucose, and botulinum toxin (Botox) injections for trigger points.

The policy specifies that trigger point injections using local anesthetic with or without corticosteroid are covered when criteria are met, but explicitly lists certain injectates and procedures as not supported. In particular, the document states that trigger injections with saline or glucose are not supported by current evidence and therefore are not covered. Additionally, the policy differentiates techniques that involve needle insertion without injection (dry needling) from covered trigger point injections and does not support their use. Finally, the policy identifies that botulinum toxin (Botox) injections for trigger points are not supported by current evidence and are excluded from coverage.

Providers should note that the policy's unsupported list reflects current evidence limitations rather than billing guidance for other procedures. The policy specifically calls out needle stimulation without injectate (dry needling) and trigger injections using saline or glucose as modalities for which evidence is insufficient to demonstrate improved patient outcomes. It also names Botox (botulinum toxin) for trigger point injections as not supported. Claims or requests for these injectates or techniques should be considered non-covered per the policy language.

inv-08: Response threshold for additional injections

Response thresholdPrior injections resulted in ≥50% pain relief with functional improvement lasting ≥6 weeks

Required documentationDocumentation must show objective evidence of ≥50% pain relief with functional improvement when requesting additional injections

Timing relationReturn of symptoms or deterioration must occur after ≥6 weeks of improvement to qualify for additional injections

Provider Actions and Documentation Requirements

Prior Authorization

Prior Authorization Required

Prior authorization is required for covered trigger point injection CPT codes. The provider must document prior conservative therapies and other required elements as outlined below.

Affected CPT codes: 20552, 20553

Step Therapy

Conservative Therapy Requirement

Conservative treatments must be attempted and documented prior to performing trigger point injections unless contraindicated or not tolerated. Required conservative therapies include: NSAID therapy (unless contraindicated), a trial of physical therapy/chiropractic care or a prescribed home exercise program (or documentation that the member is unable to tolerate these therapies), and activity modification.

Documentation Required

Required Documentation Elements

Document the diagnosis and treatment course clearly in the medical record. Documentation must include identification of trigger points by palpation, note that trigger points are focal (not widespread/fibromyalgia), documentation of prior conservative therapies attempted and the member's response (including duration of therapy and reasons for discontinuation if applicable), and that injections are intended to facilitate mobilization and rehabilitation rather than serve as the sole treatment.

Denial Risk

Unsupported CPT Codes — Denial Risk

Claims submitted with CPT 20560 or 20561 for trigger point injections are not supported under this policy and may be denied.

Unsupported CPT codes: 20560, 20561

Background

A trigger point is described in the policy context as a localized hyperirritable focus within a palpable taut muscle band that can produce tenderness and referred pain when compressed. Trigger points may arise from repetitive strain, overload, or underlying degenerative or inflammatory conditions. The policy notes that evidence for the effectiveness of various trigger therapies is mixed and that some modalities lack sufficient high-quality data demonstrating durable patient benefit.

Definitions

inv-14: Trigger point — definition

DefinitionA discrete, hyperirritative focus found in a palpable taut band in skeletal muscle or fascia that is sensitive to touch and produces characteristic referral patterns and tenderness when compressed.

LocationOccurs in any skeletal muscle and/or muscle fascia on the body

Clinical featuresTender to palpation and may produce referral patterns and autonomic phenomena

Conservative Treatment Requirements

document prior conservative therapy or intolerance

Covered when ALL of the following are met:

Conservative therapy prior to injections: Document failure of at least 3 weeks of conventional multidisciplinary medical therapy prior to initial trigger point injections, which must include: NSAID therapy unless contraindicated or not tolerated; chiropractic, physical therapy, or a prescribed home exercise program (or documented inability to tolerate such therapy); and activity modification. Documented intolerance or contraindication may substitute for trial.

Frequency Limits and Session Restrictions

inv-16: trigger point injections — spacing and maximum total sessions guidance

Minimum spacing for additional sessionsInjections for additional therapeutic series must be given at least two months apart

Maximum total sessionsPolicy references a maximum of six total sessions within 12 months from the initial injection (document notes up to six total sessions)

Service countingWhen a given body region is injected it is considered one injection service regardless of number of injections given per visit

inv-17: diagnostic/stabilization injections

Number of sets allowedUp to two sets of injections may be given for diagnosis/stabilization for the same trigger

Minimum interval between setsSets must be at least 7 days apart

Service countingWhen a given body region is injected it will be considered one injection service regardless of how many injections are given

Imaging Requirements

Note

No formal imaging requirement for trigger point injections

Policy does not require radiographic guidance or any formal imaging for trigger point injections; the prior phrase “with or without radiographic guidance” was removed.

No formal imaging requirement is specified in the current policy text.

Not Covered / Exclusions

The policy lists the following as not covered due to insufficient supporting evidence: dry needling/needle stimulation without injection; trigger injections using saline or glucose injectate; and botulinum toxin (Botox) injections for trigger points.
