Medical Policy: 02.01.21 
Original Effective Date: October 1995 
Reviewed: January 2015 
Revised: January 2015 


Benefit Application
Benefit determinations are based on the applicable contract language in effect at the time the services were rendered. Exclusions, limitations or exceptions may apply. Benefits may vary based on contract, and individual member benefits must be verified. Wellmark determines medical necessity only if the benefit exists and no contract exclusions are applicable. This medical policy may not apply to FEP. Benefits are determined by the Federal Employee Program.

This Medical Policy document describes the status of medical technology at the time the document was developed. Since that time, new technology may have emerged or new medical literature may have been published. This Medical Policy will be reviewed regularly and be updated as scientific and medical literature becomes available.


Description: 

Temporomandibular joint dysfunction (TMJ), also known as TMD, craniomandibular jaw disorder (CMJ) or craniomandibular disorder (CMD), refers to a group of conditions associated with pain and dysfunction of the masticatory system.  Symptoms attributed to TMJ dysfunction are varied and include, but not limited to: clicking sounds in the jaw, headaches, closing or locking of the jaw due to muscle spasm (trismus) or displaced disc, pain in the ears, neck, arms and spine, tinnitus, and bruxism (clenching or grinding of teeth).

 

The diagnosis of TMJ is largely based upon the symptoms of pain and biologic variables, (e.g. joint sounds, variations from ideal disc position, clicking).  These conditions may also be found in large segments of the general populations without evidence of impairment of dysfunction that require treatment. 

 

For many patients, symptoms of TMJ dysfunction are short-term and self-limiting. Conservative treatments, such as eating soft foods, rest, heat, ice, and avoiding extreme jaw movements, and anti-inflammatory medication, are recommended prior to consideration of more invasive and/or permanent therapies, such as surgery.

 

American Association for Dental Research: A policy statement, revised in 2010
Based on clinical evidence, the AADR strongly recommends that, unless there are specific and justifiable indications to the contrary, treatment of temporomandibular disorder (TMD) patients initially should be based on the use of conservative, reversible and evidence-based therapeutic modalities. Studies of the natural history of many TMDs suggest that they tend to improve or resolve over time. While no specific therapies have been proven to be uniformly effective, many of the conservative modalities have proven to be at least as effective in providing symptomatic relief as most forms of invasive treatment. Because those modalities do not produce irreversible changes, they present much less risk of producing harm (AADR, 2010).

 

American Society of Temporomandibular Joint Surgeons (ASTJS) Consensus Clinical Guidelines (2001)
Nonsurgical treatment should be considered first for all symptomatic patients with this condition. Recommended treatment options include change in diet, nonsteroidal anti-inflammatory drugs, maxillomandibular appliances, physical therapy, and injections of corticosteroids.

 

TMJ Association (2012)
Surgical treatments are controversial and should be avoided when possible. There have been no long-term clinical trials to study the safety and effectiveness of surgical treatments for TMD, nor are there criteria to identify people who would most likely benefit from surgery.

 

Replacement of the temporomandibular joint with an artificial implant should be considered a last resort. When used in patients who have had multiple prior jaw surgeries it may improve function, but studies have shown that it generally does not significantly reduce pain. Before undergoing such surgery on the jaw joint, it is extremely important to get other independent opinions and to fully understand the benefits and risks (TMJ Association website)

Policy: 

The following non-surgical treatments performed by physical medicine providers may be considered medically necessary when services are consistent with the Wellmark Physical Medicine Guidelines, which is available at http://www.wellmark.com/e_business/provider/prov_guides.htm:

  •  Manual therapy
  • Osteopathic or chiropractic manipulation 

The following non-surgical treatments are considered investigational for treatment of TMD:

  • Dry Needling


The following diagnostic procedures are considered investigational services for treatment of TMD:

  • EMG
  • Neuromuscular junction testing
  • Somatosensory testing
  • Muscle testing
  • Standard dental radiographic procedures
  • Range of motion measurements
  • Arthroscopy for diagnosis

The following surgical treatments are considered medically necessary:

  • Arthroplasty
  • Arthroscopy
  • Arthrotomy

only when all the following conservative treatments have been unsuccessful in relieving pain of TMD.

  • NSAID use for at least 4 weeks
  • Corticosteroid injections are ineffective or contraindicated
  • Soft diet for at least 3 months
  • Orthotic use consistent for at least 3 months
  • Physical therapy continuously for a minimum of 3 months

Wellmark medical policies address the complex issue of technology assessment of new and emerging treatments, devices, drugs, etc.   They are developed to assist in administering plan benefits and constitute neither offers of coverage nor medical advice. Wellmark medical policies contain only a partial, general description of plan or program benefits and do not constitute a contract. Wellmark does not provide health care services and, therefore, cannot guarantee any results or outcomes. Participating providers are independent contractors in private practice and are neither employees nor agents of Wellmark or its affiliates. Treating providers are solely responsible for medical advice and treatment of members. Our medical policies may be updated and therefore are subject to change without notice.
