Coverage Criteria for TMJ/TMD Treatments

Medically Necessary Non‑Surgical Treatments

Non‑surgical services considered proven and medically necessary for treating disorders of the temporomandibular joint (TMJ):

Medically necessary non-surgical services: Arthrocentesis

Listed as a proven, medically necessary non-surgical treatment.

Medically necessary non-surgical services: Intra-articular injections of corticosteroids

Listed as a proven, medically necessary non-surgical treatment.

Medically necessary non-surgical services: Physical therapy

Listed as a proven, medically necessary non-surgical treatment.

Medically necessary non-surgical services: Occlusal splint (stabilization and repositioning splints)

Listed as a proven, medically necessary non-surgical treatment.

Medically necessary non-surgical services: Trigger point injections

Listed as a proven, medically necessary non-surgical treatment.

Surgical Treatments (conditional)

Selected TMJ surgical services are medically necessary in certain circumstances per referenced criteria:

Surgical services subject to InterQual/other criteria: Arthroscopy (TMJ); Discectomy (TMJ); Arthroplasty (TMJ); Reconstruction (TMJ)

Medical necessity depends on InterQual or client-defined clinical coverage criteria; see referenced InterQual guidance.

Unproven / Not Medically Necessary Services

Services identified as unproven and not medically necessary due to insufficient evidence of efficacy:

Unproven / Not medically necessary services: Biofeedback; Craniosacral manipulation/therapy; Jaw mobility mechanical stretching devices (e.g., TheraBite Jaw Motion Rehabilitation System; Jaw Dynasplint System); TM epigenetic appliances (e.g., Homeoblock; DNAS; Advanced Lightwire Functional (ALF) appliances); Multiple occlusal splints (daytime and nighttime, maxillary and mandibular)

Listed as unproven and not medically necessary in the policy.

Intra-articular corticosteroid injections (arthrogenous TMD)

Covered when evidence supports short- and intermediate-term improvement in pain and mouth opening relative to conservative care, with documentation of arthrogenous diagnosis and rationale.

Intra-articular corticosteroid injection criteria: Evidence from systematic reviews, network meta-analyses and randomized trials indicates intra-articular corticosteroid injections provide greater short-term (<=5 months) and intermediate-term (>6 months to 4 years) pain control and improvement in maximum mouth opening compared with placebo or conservative therapy, although overall evidence quality ranges from very low to moderate.evidence-based justification

Document arthrogenous TMJ diagnosis and prior conservative therapies when applicable.

Trigger point / needling therapies for myofascial TMD

Covered when chosen as part of multimodal management for myofascial pain with documented failure or intolerance to baseline conservative measures; evidence limited by low study quality.

Needling therapy evidence summary: Network meta-analysis of 21 RCTs (959 participants) found short-term improvements in pain and maximum mouth opening with interventions including local anesthesia, dry needling, PRP and botulinum toxin‑A, but overall study quality was low to very low and no definitive superiority was established.trial-level evidence

Document type of needling, target muscles, and prior conservative treatments.

Physical therapy and manual therapy

Covered with clinical documentation; considered effective adjunct to splint therapy for myogenic TMD.

PT with splint: Randomized evidence (Romeo et al. 2024) demonstrated that adding physical therapy to occlusal splint therapy and education significantly improved pain and patient-reported outcomes versus splint plus education alone; manual therapy and therapeutic exercises provide medium-term benefit, and combination therapy can sustain effects longer.improvement at 3-6 months

Document PT modalities, course and patient response; note limitations such as dropout and follow-up duration.

Occlusal splints

Covered as conservative therapy; choice of splint type may be individualized.

Occlusal splint evidence: Network meta-analyses (48 RCTs) and systematic reviews report that certain splint types (anterior repositioning splints, hard stabilization splints, mini-anterior splints) can reduce pain in the short term; multimodal therapy combining counseling with hard stabilization splints may yield the greatest improvement. Document splint type and clinical response.document splint type and clinical response

Long-term benefits may equalize with other therapies; continuous daytime use can influence efficacy.

Biofeedback and behavioral therapies

Covered as adjunctive therapy with limited evidence; may be considered when targeting masticatory muscle activity or pain coping.

Biofeedback evidence: Systematic reviews and randomized trials provide low-quality evidence that biofeedback reduces masticatory muscle activity and can improve pain, disability, and pain‑coping skills, with effects comparable to occlusal splints in some trials.document therapy type and sessions

Consider biofeedback-based CBT (BFB-CBT) for patients who would benefit from psychological coping interventions; document modality and treatment course.

Jaw mobility mechanical stretching devices

Not established / unproven — limited evidence for efficacy and concerns about compliance.

Stretching device stance: Randomized and feasibility studies of jaw mobility mechanical stretching devices (e.g., TheraBite, Jaw Dynasplint) show inconsistent long-term benefit versus conventional exercises, limited participant numbers, short follow-up, and notable compliance issues; evidence quality is insufficient to establish efficacy or safety.insufficient evidence

These devices are considered unproven and may be denied or reviewed case-by-case; document prior physical therapy failure and functional impairment if requesting coverage.

Epigenetic appliances and craniosacral manipulation

Not covered / investigational due to lack of quality evidence.

Insufficient evidence: Literature review did not identify quality evidence to support efficacy of epigenetic appliances or craniosacral manipulation for TMJ disorders; therefore these modalities are considered investigational and not medically necessary.no high-quality trials

Examples include Homeoblock, DNAS, Advanced Lightwire Functional (ALF) appliances and craniosacral therapy.

Multiple occlusal splints used concurrently (for example, separate daytime and nighttime splints or simultaneous maxillary and mandibular appliances) are listed in this policy as unproven and not medically necessary due to insufficient evidence that combining or providing more than one splint device improves health outcomes compared with standard conservative care or a single appropriately selected splint.

Jaw mobility devices billed under the HCPCS E1700 series (and related supply codes) and craniosacral manipulation/therapy (for which 90901 and E0746 are referenced in the policy code list) are identified among therapies considered unproven. The policy cites insufficient quality evidence to establish efficacy or consistent clinical benefit for these modalities in TMJ/TMD management.

Craniosacral manipulation/therapy and TM epigenetic appliances are excluded from coverage in this policy because literature review did not identify quality evidence to support their efficacy for temporomandibular joint disorders. The policy states the effect on health outcomes cannot be established for these modalities and lists them as investigational/not covered.

The revised policy explicitly names jaw mobility mechanical stretching devices (for example, the TheraBite Jaw Motion Rehabilitation System and the Jaw Dynasplint System) among services considered unproven and not medically necessary. The update replaced prior terminology (passive rehabilitation and low-load prolonged-duration stretch devices) with this specific device category and examples.

The policy summarizes a group of therapies as unproven or not medically necessary for treating TMJ/TMD. The list includes biofeedback, craniosacral manipulation/therapy, jaw mobility mechanical stretching devices (e.g., TheraBite, Jaw Dynasplint), TM epigenetic appliances (e.g., Homeoblock, DNAS, ALF), and multiple occlusal splints (daytime/nighttime or maxillary/mandibular combinations). Insufficient quality evidence was cited for these interventions.

Jaw mobility mechanical stretching devices are considered unproven and not medically necessary for treatment of TMD because available studies are limited by small sample sizes, short follow-up, inconsistent benefit versus conventional stretching or exercises, and compliance concerns; therefore the evidence is insufficient to establish efficacy or safety for routine coverage.

Administrative note: the policy revision specifically updates the list of unproven and not medically necessary services to name jaw mobility mechanical stretching devices (e.g., TheraBite, Jaw Dynasplint) as not medically necessary. Supporting information and references were updated and the previous policy version was archived.

Provider Actions, Documentation, and Utilization Management

Prior Authorization

InterQual-referenced Services May Require Prior Authorization

Some services referenced in this policy are evaluated using InterQual criteria and may require prior authorization. Providers should verify member-specific benefits and prior authorization requirements before scheduling or performing InterQual-referenced procedures.

InterQual may be used to determine medical necessity for certain procedures

Prior Authorization

Prior Authorization Recommended for Jaw Stretching Devices

Jaw mobility mechanical stretching devices (e.g., TheraBite, Jaw Dynasplint) are considered unproven due to limited and low-quality evidence. Prior authorization is recommended when these devices are requested so the plan can review clinical justification and member-specific coverage.

Devices have mixed/insufficient evidence of efficacy and safety
FDA issued a safety communication (March 2023) raising concerns about certain jaw remodeling devices for adults

Background and Evidence Summary

Temporomandibular disorders (TMD) represent a heterogeneous group of conditions affecting the temporomandibular joint and surrounding masticatory musculature, presenting with symptoms such as jaw pain, limited range of motion, joint noises, and functional impairment. Conservative, reversible measures (for example, rest, soft diet, NSAIDs, splints, physical therapy) are recommended initially; when these fail, targeted interventions (injections or selected surgical procedures) may be considered per the policy's evidence-based criteria.

Definitions and Key Terms

Occlusal splints — definition and intended effects

DefinitionOral appliances (stabilization/night guards or mandibular repositioning devices) that cover some or all teeth in an arch and are intended to reduce or eliminate clenching/bruxism and to keep or reposition the jaw in a more relaxed position.

Common typesStabilization splints (night guards) and mandibular repositioning splints/devices.

Intended effectsReduce clenching/bruxism, reposition the mandible, decrease myofascial pain, and improve jaw function and comfort.
