This Clinical Policy Bulletin explains how we determine whether certain services or supplies are medically necessary. We made these decisions based on a review of currently available clinical information including:
- Clinical outcome studies in the peer-reviewed published medical and dental 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 and dentists practicing in relevant clinical areas
- Other relevant factors
We expressly reserve the right to revise these conclusions as clinical information changes, and welcome further relevant information.
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.

Aetna considers a temporary anchorage device (TAD) to be a device that is temporarily attached to bone to enhance orthodontic anchorage. The procedure includes the device removal.
A temporary anchorage device (TAD) is a biocompatible device that is fixed to bone to enhance orthodontic anchorage and/or overcome anchorage limitations. It is used during procedures to move teeth by either supporting the teeth of the reactive unit or by preventing the need for the reactive unit altogether. The TAD is removed after treatment and the removal is considered part of the overall TAD procedure. TADs may be located transosteally, subperiosteally or endosteally and may be fixed to bone either mechanically (cortically stabilized) or biochemically (osseointegrated).
TADs are generally manufactured with a smooth endosseous surface and/or additional surface treatments to actively discourage osseointegration and simplify their removal.
Osseointegrated dental implants, either conventional (D60101) or mini-implants (D60131), placed for the ultimate purpose of supporting a prosthesis are not considered temporary anchorage devices. They are not removed and discarded after orthodontic treatment. This is true even though they may be used for orthodontic anchorage.
