    OpenPayer is powered by Trek Health's payer performance platform. Trek continuously ingests, validates, and normalizes Transparency in Coverage data alongside payer policies and other commercial payer data to create a structured payer intelligence foundation. OpenPayer uses this foundation to deliver personalized search results, dynamically generated policy pages, and tailored policy monitoring based on each user's payers, specialties, billing codes, and areas of interest. The same intelligence powers broader payer performance workflows, including reimbursement benchmarking, contract evaluation, payer negotiations, and financial decision-making.

    Coverage Criteria for Trigger Point Injections

    Initial Therapy

    Covered when ALL of the following are met

    Initial Diagnostic/Stabilization: 1) Member has myofascial pain that has persisted for more than three months causing tenderness and/or weakness, restricting motion and/or causing referred pain when compressed; 2) Member has failed ≥ 3 weeks of conventional multidisciplinary medical therapy including: (i) chiropractic, physical therapy, or prescribed home exercise program or inability to tolerate such therapy (injection may be used as a bridge to therapy); (ii) NSAID unless contraindicated or not tolerated; (iii) activity modification; 3) Trigger points have been identified by palpation; 4) Trigger points are located in a few discrete areas and are not associated with widespread areas of muscle tenderness (e.g., fibromyalgia); 5) Injections are not used as the sole method of treatment but are intended to facilitate mobilization to allow non-invasive modalities (e.g., physical therapy) for muscle strengthening, flexibility, and functional restoration; 6) Up to two sets of injections at least seven days apart may be given for diagnosis and stabilization for the same trigger point; when a given body region is injected it will be considered one injection service regardless of number of injections.

    From Policy I.A-D

    Continuation Therapy / Additional Sessions

    Covered when ALL of the following are met

    Additional injections: A) Prior injections resulted in ≥ 50% pain relief with functional improvement for ≥ 6 weeks; B) There was return of pain and/or deterioration following ≥ 6 weeks of improvement; C) Injections are given at least two months apart for up to 12 months from the initial injection (maximum of six total sessions); D) Injections are not used as the sole method of treatment but are intended to facilitate mobilization to allow non-invasive modalities (e.g., physical therapy) for muscle strengthening, flexibility, and functional restoration; when a given body region is injected, it is considered one injection service regardless of number of injections.

    From Policy II and III.C

    Unproven / Not Supported Indications

    Not supported interventions: Dry needle stimulation of trigger points; trigger point injection with saline or glucose; use of Botox during trigger point injections.

    Current evidence does not support these uses

    The policy does not support certain trigger point techniques due to insufficient evidence. Specifically, dry needling (needle insertion without injection), trigger point injection with saline or glucose, and the use of botulinum toxin (Botox) during trigger point injections are not supported. Providers should avoid billing these approaches as covered trigger point injection services under this policy and follow the defined coverage criteria for supported procedures.

    Provider Requirements and Billing

    Prior Authorization

    Prior Authorization and Coding

    Prior authorization is required for trigger point injections. Use CPT 20552 or 20553 for covered trigger point injection services. Prior authorization must be obtained when applying the coverage criteria in this policy.

    • Covered CPT: 20552, 20553
    • Not covered CPT (no support for criteria): 20560, 20561
    Step Therapy

    Conservative Therapy Requirement

    Conservative, multidisciplinary therapy must be tried and documented for at least 3 weeks prior to diagnostic/stabilization trigger point injections. Therapies should include physical modalities and medications unless contraindicated; injections may be used as a bridge when such therapies are not tolerated.

    • Required conservative therapies: chiropractic, physical therapy, or prescribed home exercise program (or documented inability to tolerate these)
    • Medication: NSAID unless contraindicated or not tolerated

    Background

    Trigger points are hyperirritable foci in taut muscle bands that can produce local and referred pain. Trigger point injections with local anesthetic, with or without corticosteroid, are performed both diagnostically and therapeutically to relieve myofascial pain and to facilitate mobilization so patients can engage in non-invasive treatments such as physical therapy. This policy frames injections as an adjunct — not as sole therapy — and permits up to two sets of injections at least seven days apart for diagnosis/stabilization, with additional sessions subject to continuation criteria.

    Key Definitions

    inv-14: Trigger point — discrete hyperirritative focus definition
    DefinitionA discrete, hyperirritative focus in a palpable taut muscle band that is sensitive to touch and can produce referral pain patterns, tenderness, and autonomic phenomena.
    LocationOccurs in any skeletal muscle and/or muscle fascia on the body
    Clinical significanceProduces local and referred pain when compressed

    Required Conservative Treatment

    Prior conservative therapy trial

    Covered when ALL of the following are met

    Prior conservative therapy trial: Member has failed at least 3 weeks (≥ 3 weeks) of conventional multidisciplinary medical therapy including chiropractic, physical therapy, or prescribed home exercise program (or is unable to tolerate such therapy), NSAID unless contraindicated or not tolerated, and activity modification prior to diagnostic/stabilization injections.≥ 3 weeks

    Imaging Requirements

    Note

    Imaging — none specified

    No imaging or radiographic guidance is specified or required for trigger point injections in this policy.

    Not Covered

    Not covered: current evidence does not support the following uses of trigger point therapies and they are therefore not covered under this policy: dry needle stimulation of trigger points; trigger point injection with saline or glucose; and use of Botox during trigger point injections.

  1. Activity modification
    2. Documentation Required

    Required Clinical Documentation

    Clinical documentation must support medical necessity: myofascial pain > 3 months with tenderness/weakness or referred pain; identification of trigger points by palpation; location limited to discrete areas (not widespread as in fibromyalgia); documentation that injections are adjunctive to facilitate non-invasive modalities.

    • Duration: myofascial pain persisting > 3 months
    • Conservative therapy: ≥ 3 weeks of multidisciplinary therapy documented
    • Trigger point identification: palpation documented
    • Anatomic limitation: few discrete areas, not widespread/fibromyalgia
    • Treatment intent: adjunct to mobilization and rehabilitation
    Denial Risk

    Denial Triggers for Medical Necessity

    Denials may result if documentation is insufficient. Common denial triggers include lack of documented conservative therapy, absence of palpation-confirmed trigger points, evidence of widespread muscle tenderness (e.g., fibromyalgia), use of injections as sole therapy, or use of non-supported techniques (dry needling, saline/glucose injections, or Botox for trigger points).

    • Insufficient conservative therapy or lack of documentation
    • No palpation documentation of trigger points
    • Widespread muscle tenderness (suggests fibromyalgia)
    • Injections documented as sole method of treatment
    • Use of unsupported techniques: dry needling, saline/glucose injections, Botox
