Medical Necessity and Coverage Criteria

Proven and Medically Necessary Nonsurgical Services

The following nonsurgical services are proven and medically necessary for treating disorders of the temporomandibular joint (TMJ):

Covered nonsurgical services

Intra-articular corticosteroid injection: Intra-articular injection of corticosteroids for treatment of a TMJ disorder.
Occlusal splint therapy, including stabilization or repositioning splints, for treatment of a TMJ disorder.

TMJ Arthroplasty

TMJ arthroplasty is proven and medically necessary in certain circumstances.

TMJ arthroplasty is medically necessary when the applicable clinical coverage criteria are met.

Refer to InterQual CP: Procedures, Arthroplasty, Temporomandibular Joint (TMJ) for the medical necessity criteria.

Unproven and Not Medically Necessary Services

The following services are unproven and not medically necessary for treating disorders of the TMJ due to insufficient evidence of efficacy; this list is not all inclusive.

Unproven TMJ services

Biofeedback.
Jaw mobility mechanical stretching devices, such as the TheraBite Jaw Motion Rehabilitation System or Jaw Dynasplint System.
Multiple occlusal splints, such as daytime and nighttime splints or maxillary and mandibular splints.
Epigenetic appliances, such as Homeoblock, DNA Daytime/Nighttime appliance, or Advanced Lightwire Functional appliance.

Jaw Mobility Mechanical Stretching Devices

Jaw mobility mechanical stretching devices are considered unproven.

Unproven jaw mobility mechanical stretching devices: Jaw mobility mechanical stretching devices for temporomandibular disorders are considered unproven due to insufficient quality evidence of efficacy and safety, limited adherence, short follow-up, small studies, and inconclusive or unfavorable findings.

The evidence cited includes studies in head and neck cancer-related trismus and may not generalize to temporomandibular disorders.

Biofeedback

Biofeedback evidence is insufficient for establishing outcomes as an isolated treatment.

Biofeedback evidence limitation: The effect of biofeedback as an isolated treatment for temporomandibular disorders cannot be established; available studies generally evaluate biofeedback in combination with established treatment or use low-quality evidence.

Biofeedback may be beneficial for somatic awareness, parafunctional habits, or coping when combined with established treatment, but standardized protocols and longer follow-up are needed.

Jaw Mobility Mechanical Stretching Devices

Jaw mobility mechanical stretching devices are considered unproven for TMDs.

Jaw mobility mechanical stretching devices for TMDs are unproven because the published evidence is limited to small studies, short-term follow-up, substantial loss to follow-up, inconclusive or unfavorable findings, limited adherence, and unestablished impact on clinical outcomes.

Evidence cited includes studies of TheraBite and Jaw Dynasplint devices; findings from cancer-related trismus populations may not generalize to all individuals with TMJ disorders.

Epigenetic Appliances

Epigenetic appliances are considered unproven for treatment of TMJ disorders.

Epigenetic appliances: Quality evidence supporting the efficacy of epigenetic appliances for treatment of TMJ disorders has not been identified, and the effect on health outcomes cannot be established.

TMJ Surgical Treatment and Arthroplasty

TMJ arthroplasty is described as proven and medically necessary in certain circumstances. The applicable medical necessity criteria reference is InterQual CP: Procedures, Arthroplasty, Temporomandibular Joint (TMJ).

Surgical treatment sequencing: Surgical treatment should follow appropriate history, examination, imaging, and diagnosis; nonsurgical or minimally invasive treatment should be attempted before definitive surgery, and surgery for internal derangement should be reserved for cases in which nonsurgical therapy has been ineffective and pain and/or dysfunction are moderate to severe.

Surgery is not indicated for asymptomatic or minimally symptomatic patients or for preventive reasons when the patient has no pain and satisfactory function. Arthroplasty and total joint replacement should be reserved for patients in whom minimally invasive procedures have not been successful.

Many member benefit documents contain explicit exclusions for services used to diagnose or treat temporomandibular joint disease, whether the services are medical or dental. Coverage must therefore be determined under the member-specific benefit plan and any applicable federal or state mandates.

The policy identifies a lack of published studies addressing treatment of TMJ disorders with more than one occlusal splint at a time, such as daytime and nighttime appliances or simultaneous maxillary and mandibular appliances. A beneficial effect on health outcomes therefore cannot be established.

Surgical intervention is not indicated for asymptomatic or minimally symptomatic patients. Surgery is also not indicated for preventive purposes when the patient has no pain and satisfactory function; for internal derangement, surgery should generally be considered only after nonsurgical therapy has been ineffective and pain and/or dysfunction are moderate to severe.

FDA approval or device classification alone is not a basis for coverage. FDA regulation or classification of a temporomandibular joint device does not, by itself, establish that the associated service or device is covered.

The policy identifies the following services as unproven and not medically necessary for TMJ disorders because of insufficient evidence of efficacy: biofeedback, jaw mobility mechanical stretching devices, multiple occlusal splints, and epigenetic appliances. This list is not all inclusive.

Jaw mobility mechanical stretching devices are considered unproven because available evidence is limited in quality and includes small studies, short follow-up, substantial loss to follow-up, and findings that are often inconclusive or unfavorable. Adherence is limited, and the evidence does not establish efficacy, safety, or an impact on clinical outcomes; findings from cancer-related trismus populations may not generalize to patients with TMJ disorders.

Epigenetic appliances are considered unproven for TMJ disorders because a review of the medical literature did not identify quality evidence supporting their efficacy, and their effect on health outcomes cannot be established.

Note

Use the Revised TMJ Arthroplasty Criteria

Use the revised medical-necessity clinical coverage criteria reference for TMJ arthroplasty: InterQual® CP: Procedures, Arthroplasty, Temporomandibular Joint (TMJ).

Step Therapy

Conservative Treatment Before Surgery

Before considering surgery, document that treatment initially used conservative, reversible, and evidence-based modalities. Surgical treatment should follow appropriate evaluation and attempted least-invasive nonsurgical or minimally invasive treatment when clinically indicated.

Arthroplasty and total joint replacement should be reserved for patients in whom minimally invasive procedures have not been successful.
Surgery is indicated only when nonsurgical therapy has been ineffective and pain and/or dysfunction are moderate to severe.

Temporomandibular Disorders

Temporomandibular disorders are diverse conditions affecting the temporomandibular joint and surrounding musculature. Clinical presentations may include pain, limited jaw motion, and clicking, popping, or crepitus. Symptoms may resolve and recur or respond to conservative treatment, including medication, a soft diet, jaw rest, moist heat, physical therapy, splints, muscle relaxants, and antidepressants. When conservative treatment is unsuccessful, injection therapy or surgery, including joint replacement, may be considered; treatment should use the most conservative and reversible approach possible.

Key Terms

Arthrocentesis

ProcedureArthrocentesis (lavage) is a minimally invasive procedure in which irrigants are injected into the joint space.

PurposeThe procedure is intended to remove inflammatory mediators or increase mobility by removing intra-articular adhesions.

Occlusal Splint Therapy

DefinitionOcclusal splint therapy uses an intraoral splint to treat myofascial pain dysfunction and temporomandibular joint disorders.

Device typesTherapy consists of either a stabilization splint—also called a night guard or occlusal guard—or a mandibular repositioning splint/device.

Treatment purposeThe devices are intended to reduce or eliminate clenching or bruxism (tooth grinding) and keep or reposition the jaw in a more relaxed position.

Documentation Required

Medical Records for Clinical Review

Maintain medical records needed for clinical review to assess whether the member meets the applicable clinical criteria. Documentation supports review but does not guarantee coverage of the requested service.

Records may include information relevant to clinical-criteria eligibility and the requested service.
Coverage remains subject to the member-specific benefit plan document and applicable laws.

Billing Rule

Verify Member Benefits

Verify the member-specific benefit document and applicable federal or state mandates before using this policy. Benefit coverage is determined by the member’s plan terms and applicable law.

Many benefit documents explicitly exclude services to diagnose or treat temporomandibular joint disease, whether medical or dental in nature.

Unsupported block type: documentation

Denial Risk

Unproven TMJ Services

The services identified as unproven are not medically necessary under this policy and may be denied, subject to the member’s benefit plan and applicable terms.

Jaw mobility mechanical stretching devices
Multiple occlusal splints
Epigenetic appliances

Plan Benefit Exclusions

Check for explicit plan exclusions before recommending or billing services to diagnose or treat temporomandibular joint disease. Exclusions may apply to both medical and dental services.

Review the member-specific benefit document and applicable federal or state mandates.

Billing Rule

Code Listing Does Not Guarantee Payment

The inclusion of a procedure or diagnosis code in this policy is for reference only and does not establish that the service is covered or non-covered. Code listing does not create a right to reimbursement or guarantee claim payment.

The code list may not be all inclusive.
Other policies and guidelines may apply.
Coverage is determined by the member-specific benefit plan document and applicable laws.

Denial Risk

Jaw Mobility Stretching Devices Are Unproven

Jaw mobility mechanical stretching devices, such as the TheraBite Jaw Motion Rehabilitation System® and Jaw Dynasplint® System, are considered unproven because quality evidence of efficacy and safety is insufficient. Services may be denied as not medically necessary.

Published studies are limited by small sample sizes, short follow-up, loss to follow-up, and inconclusive or unfavorable findings.
Adherence is limited, and the impact on clinical outcomes cannot be established.

Denial Risk

Isolated Biofeedback Lacks Established Efficacy

Isolated biofeedback lacks sufficient quality evidence to establish an effect on health outcomes. Evidence involving biofeedback combined with other treatment modalities does not establish efficacy as an isolated treatment.

Existing studies have low quality, small sample sizes, short treatment and follow-up periods, and nonstandardized protocols.

Denial Risk

Multiple Splints Lack Supporting Evidence

There are no published studies addressing treatment of TMJ disorders with more than one occlusal splint at a time; therefore, a beneficial effect of multiple splints cannot be established.

Examples include daytime and nighttime appliances or maxillary and mandibular appliances.

Denial Risk

Mechanical Jaw Stretching Devices Are Unproven

Jaw mobility mechanical stretching devices are unproven because the available evidence is limited or inconclusive and does not establish efficacy, safety, adherence, or improved clinical outcomes.

Published evidence includes small studies, short-term follow-up, substantial loss to follow-up, and unfavorable or inconclusive findings.
Low adherence further limits the ability to establish a clinical benefit.

Denial Risk

Epigenetic Appliances Are Unproven

A review of the medical literature did not identify quality evidence supporting the efficacy of epigenetic appliances for TMJ disorders, and their effect on health outcomes cannot be established.

Examples include Homeoblock™, DNA® daytime/nighttime appliances, and Advanced Lightwire Functional appliances.

Billing Rule

FDA Approval Alone Does Not Establish Coverage

FDA approval or device classification alone does not establish coverage. Coverage remains subject to the member-specific benefit plan, applicable mandates, and other applicable policies and guidelines.

FDA approval alone is not a basis for coverage.
TMJ prostheses are regulated as Class III devices; continuous passive motion machines are Class II devices.
Review applicable FDA safety information for jaw remodeling devices.

ConstructionSplints are made of a variety of materials and cover all or some teeth in an individual arch.

Myofascial Trigger Points

DefinitionMyofascial trigger points are focal knots in a band of skeletal muscle caused by acute or repeated microtrauma.

TMJ relevanceThis condition is common in disorders of the temporomandibular joint.

Treatment effectInjections may relax the muscle fibers, allow lengthening of the muscle fiber, and remove metabolite waste.

Treatment relevanceThese effects assist in breaking the pain-tension cycle; treatment may involve dry needling alone or may be followed by an injection of corticosteroid, dextrose, or saline.

Epigenetic Appliances

DefinitionEpigenetic appliances are intraoral devices similar in appearance to orthodontic retainers.

Purported mechanismThe premise is that overnight wear applies pressure to the jaws, resulting in expansion through stimulation of osteoblasts and osteoclasts.

Scientific conceptEpigenetics examines how external factors affect gene activity without altering the DNA sequence.

Purported usesThese appliances are purported to help conditions including TMJ disorders, sleep apnea, and chronic headaches.
