Important note

 

This Clinical Policy Bulletin determines whether certain services or supplies are medically necessary, experimental, and investigational, or cosmetic. Aetna® has reached these conclusions based upon a review of currently available clinical information (including clinical outcome studies in the peer-reviewed published medical literature, regulatory status of the technology, evidence -based guidelines of public health and health research agencies, evidence-based guidelines and positions of leading national health professional organizations, views of physicians practicing in relevant clinical areas, and other relevant factors).

 

Aetna makes no representations and accepts no liability with respect to the content of any external information cited or relied upon in the Bulletin.  The discussion, analysis, conclusions, and positions reflected in this Bulletin, including any reference to a specific provider, product, process or service by name, trademark, manufacturer, constitute an opinion by Aetna and are made without any intent to defame.

 

Aetna expressly reserves the right to revise these conclusions as clinical information changes, and welcomes further relevant information including correction of any factual error. CPBs include references to standard HIPAA compliant code sets to assist with search functions and to facilitate billing and payment for covered services. New and revised codes are added to the CPBs as they are updated. When billing, you must use the most appropriate code as of the effective date of the submission. Unlisted, unspecified and nonspecific codes should be avoided. 

 

Each benefits plan defines which services are covered, excluded and subject to dollar caps or other limits. Members and their dentists will need to refer to the member's benefits plan to determine if any exclusions or other benefits limitations apply to this service or supply.

 

The conclusion that a particular service or supply is medically necessary does not guarantee that this service or supply is covered (that is, will be paid for by Aetna) for a particular member. The member's benefits plan determines coverage. Some plans exclude coverage for services or supplies that we consider medically necessary. If there is a discrepancy between this policy and a member's plan of benefits, the benefits plan will govern. In addition, coverage may be mandated by applicable legal requirements of a state, the federal government or CMS for Medicare and Medicaid members.

Policy

 

We consider occlusal adjustment to be part of and inclusive to restorative, prosthodontic and endodontic services. Occlusal adjustment is appropriate during any phase of periodontal therapy, except in the case of acute conditions. Occlusal adjustment (limited and/or complete) is considered to be therapeutic for the treatment of etiologic factors of occlusal trauma to enable patients to maintain a comfortable and functional dentition. Aetna does not consider occlusal adjustment the sole treatment modality for the management or prevention of a temporomandibular disorder (TMD).  

 

Background

 

Occlusal adjustment (odontoplasty) is the reshaping of occlusal surfaces of teeth to create a harmonious contact relationship between maxillary and mandibular teeth. A primary objective of occlusal adjustment is improvement of the functional relations of the dentition in such a way that the teeth and the periodontium will receive uniform stimulation and the occlusal surfaces of the teeth will be exposed to an even physiologic wear.

 

The rationale for doing an occlusal adjustment can be grouped into the following categories:
 

  1. Elimination of traumatic occlusion
  2. Stabilization of orthodontic results
  3. Establishment of an optimal occlusal pattern prior to extensive restorative procedures

Complete (full-mouth) occlusal adjustments are performed to achieve functional relationships and improve masticatory efficiency. It may be necessary to perform odontoplasty to occlusal surfaces of numerous teeth to establish or maintain occlusal harmony. Treatment is directed toward the elimination or minimization of excessive force or stress placed on the teeth and/or tooth.

 

Occlusal adjustments are necessary when they are essential to reduce or eliminate traumatic occlusion or when teeth are compromised from loss of periodontal support. Occlusal adjustments may be integral to a comprehensive restorative treatment or part of treatment to correct skeletal and occlusal disharmonies. A complete occlusal adjustment may require multiple visits, is considered part of comprehensive orthodontic treatment and is integral to orthognathic surgery.

 

Occlusal adjustments are of limited value as the sole treatment modality for the management or prevention of TMD. Scientific evidence does not support the performance of occlusal adjustment as a general method for treating a non-acute TMD, bruxism or headaches. Literature suggests that temporary reversible measures be attempted prior to permanent irreversible disengagement procedures.

 

Mounting of diagnostic casts, analysis and diagnosis are considered integral to the complete adjustment.
