Coverage Criteria for TMJ Non‑Surgical Treatments
Custom intra-oral splint coverage
Covered when ALL of the following are met:
Specified symptoms listed as children
List of possible symptoms
- Symptom 1: Extra-articular pain related to muscles of the head and neck region, or earaches, headaches, masticatory or cervical myalgia
chunk 2
- Symptom 2: Painful chewing
chunk 2
- Symptom 3: Restricted range of motion as indicated by one of specified measurements
chunk 2

Not covered / investigational treatments
chunk 3
Orthognathic surgery
chunk 3
Orthognathic surgery is generally not covered under this policy and is described as a plan-level exclusion. Providers should consult the member's specific benefit documents (Member Handbook) to determine whether orthognathic procedures are covered for a given plan.
The policy explicitly lists TMJ treatments that will not be covered, including: bite (occlusal) adjustment/equilibration; crowns, bridges, amalgams, or other restorative procedures performed solely to restore tooth alignment or balance the bite; orthodontia; appliances strictly for the treatment of bruxism (tooth grinding); Botox injections; continuous passive motion (CPM); intra‑oral appliances for headaches or trigeminal neuralgia (see investigational note); chiropractic adjustment treatments; use of TENS units unless performed by a physical therapist or a dentist; and EMG which is considered investigational.
Intra‑oral appliances when used for the treatment of headaches or trigeminal neuralgia are considered experimental and investigational due to insufficient evidence supporting their effectiveness.

Provider Actions — Prior Authorization and Documentation Requirements
Prior authorization required; affected CPT/HCPCS codes
Prior authorization is required for non-surgical TMJ treatments and should include requests for the CPT/HCPCS codes listed in the policy: 21085, 21089, 21100, 21110, 20552, 20553, 20605, 70336, 70486, 70488, and 97810.
- Include the specific procedure codes above when submitting the prior authorization request.
Document failure of 6 weeks of conservative therapy before splint coverage
Coverage of custom intra-oral prosthetic devices/splints requires documented failure to respond to a total of 6 weeks of conservative treatment that includes at least three of the listed conservative modalities.
- Minimum conservative treatment duration: 6 weeks.
- Minimum modalities tried: at least 3 (see examples in policy).
Information required with prior authorization
Submit clinical records documenting TMJ symptoms, radiographic study results, previous treatments tried, and range of motion measurements with the prior authorization request.
- Clinical records from the treating physician or dentist describing symptoms.
- Radiographic study results (Dental/Periodontal/Maxillofacial imaging).
- Details of previous treatments tried and their duration/outcomes.
- Range of motion measurements (e.g., deviation on opening, interincisal opening, protrusive/excursive and lateral movements).
Confirm benefit availability in the applicable plan documents
Benefit availability for TMJ non-surgical treatments may be limited or excluded under some plans; providers must refer to the member's applicable plan benefit wording or Member Handbook to determine coverage and plan-specific terms.
- Orthognathic surgery is typically a plan exclusion—confirm via Member Handbook.
- Some modalities (e.g., acupuncture, TENS) may have plan-specific coverage—check applicable benefits.
Background
Temporomandibular joint dysfunction encompasses a group of functional and structural disorders affecting the temporomandibular joints and the muscles of mastication. Common causes include trauma, developmental anomalies, disc dysfunction, neuromuscular disorders, condylar displacement, stress, malocclusion, arthritis, or ankylosis. Symptoms may include TMJ or masticatory muscle pain, jaw clicking or popping, restricted jaw movement or locking, muscle spasms, earache, and tinnitus.
Definitions and Clinical Measures
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.
