DESCRIPTIONTemporomandibular joint (TMJ) dysfunction refers to a group of disorders characterized by pain in the TMJ and surrounding tissues. Initial conservative therapy is generally recommended; there are also a variety of non-surgical and surgical treatment possibilities for patients whose symptoms persist.
Temporomandibular joint dysfunction (also known as TMJ disorders) refers to a cluster of problems associated with the TMJ and musculoskeletal structures. The etiology of TMJ disorders remains unclear and is believed to be multifactorial. TMJ disorders are often divided into two main categories: articular disorders (e.g., ankylosis, congenital or developmental disorders, disc derangement disorders, fractures, inflammatory disorders, osteoarthritis, and joint dislocation) and masticatory muscle disorders (e.g., myofascial pain, myofibrotic contracture, myospasm, and neoplasia).
There are no generally accepted criteria for diagnosing TMJ disorders. It is often a diagnosis of exclusion and involves physical examination, patient interview, and dental record review. Diagnostic testing and radiologic imaging is generally only recommended for patients with severe and chronic symptoms.
Symptoms attributed to TMJ dysfunction are varied and include, but are not limited to: clicking sounds in the jaw; headaches; closing or locking of the jaw due to muscle spasms (trismus) or displaced disc; pain in the ears, neck, arms, and spine; tinnitus; and bruxism (clenching or grinding of the teeth).
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.
Several muscle monitoring devices have received clearance from the U.S. Food and Drug Administration (FDA) through the 510(k) process since 1981. Some examples of these devices are: the K6-I Diagnostic System (Myotronics), the BioEMG III™ (Bio-Research Associates), and the GrindCare Measure (Medotech A/S). These devices aid clinicians in the analysis of joint sound, vibrations, and muscle contractions when diagnosing and evaluating TMJ dysfunction.
POLICYEffective 01/01/2014, prior authorization is required for temporomandibular joint disorder benefits.
Medical Necessity documentation and a treatment plan, including charges for each service, must be submitted to and approved prior to the commencement of treatment. No benefits will be provided for temporomandibular joint disorder when a Member receives services from a Non-Network Provider.
The following diagnostic procedures are considered medically necessary in the diagnosis of TMJ dysfunction:
The following diagnostic procedures are considered investigational in the diagnosis of TMJ dysfunction:
The following surgical treatments are considered medically necessary in the treatment of TMJ dysfunction:
The following non-surgical treatments are considered medically necessary in the treatment of TMJ dysfunction:
The following non-surgical treatments are considered investigational in the treatment of TMJ dysfunction:
POLICY EXCEPTIONSState Health Plan (State and School Employees) and Federal Employee Program (FEP) members: Refer to the Member's Plan for benefits, limitations, and/or exclusions for these services.
Medically Necessary is defined as those services, treatments, procedures, equipment, drugs, devices, items or supplies furnished by a covered Provider that are required to identify or treat a Member's illness, injury or Nervous/Mental Conditions, and which Company determines are covered under this Benefit Plan based on the criteria as follows in A through D:
A. consistent with the symptoms or diagnosis and treatment of the Member's condition, illness, or injury; and
B. appropriate with regard to standards of good medical practice; and
C. not solely for the convenience of the Member, his or her Provider; and
D. the most appropriate supply or level of care which can safely be provided to Member. When applied to the care of an Inpatient, it further means that services for the Member's medical symptoms or conditions require that the services cannot be safely provided to the Member as an Outpatient.
For the definition of Medically Necessary, “standards of good medical practice” means standards that are based on credible scientific evidence published in peer-reviewed medical literature generally recognized by the relevant medical community, and physician specialty society recommendations, and the views of medical practitioners practicing in relevant clinical areas and any other relevant factors. BCBSMS makes no payment for services, treatments, procedures, equipment, drugs, devices, items or supplies which are not documented to be Medically Necessary. The fact that a Physician or other Provider has prescribed, ordered, recommended, or approved a service or supply does not in itself, make it Medically Necessary.
Investigative is defined as the use of any treatment procedure, facility, equipment, drug, device, or supply not yet recognized as a generally accepted standard of good medical practice for the treatment of the condition being treated and; therefore, is not considered medically necessary. For the definition of Investigative, “generally accepted standards of medical practice” means standards that are based on credible scientific evidence published in peer-reviewed medical literature generally recognized by the relevant medical community, and physician specialty society recommendations, and the views of medical practitioners practicing in relevant clinical areas and any other relevant factors. In order for equipment, devices, drugs or supplies [i.e, technologies], to be considered not investigative, the technology must have final approval from the appropriate governmental bodies, and scientific evidence must permit conclusions concerning the effect of the technology on health outcomes, and the technology must improve the net health outcome, and the technology must be as beneficial as any established alternative and the improvement must be attainable outside the testing/investigational setting.The coverage guidelines outlined in the Medical Policy Manual should not be used in lieu of the Member's specific benefit plan language. Note that most member's benefits have a dollar lifetime limit on TMJ services which include all services related to TMJ including diagnosis and treatment.
