Treatment of Peri-implantitis (036)

Number: 036
(Updated)

Subject: Treatment of Peri-implantitis

Date: September 23, 2013

Important Note

This Clinical Policy Bulletin expresses our determination of whether certain services or supplies are medically necessary. We reached these conclusions 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 consult 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

Despite large numbers of publications available regarding peri-implantitis treatments, there are no long term studies which indicate that the uses of osseous contouring, placement of barriers or bone grafts are superior to flap reflection with debridement. Therefore, Aetna considers flap reflection with debridement as the accepted clinical protocol for peri-implantitis treatment.

Background

Peri-implantitis is defined as an inflammatory process affecting the tissues around an osseointergrated implant in function resulting in loss of supporting bone. Clinical signs are deep probing depth (> 5 mm) bleeding and/or suppuration on probing. Loss of supporting bone usually forms a circumferential crater defect. Large scale studies detected peri-implantitis in 12% of implants in function for at least five years and 43% of implants in function for 9-14 years. Biofilms consist predominately of gram negative anaerobes and are similar to those found in chronic periodontits, but bone loss is more rapid in peri-implantitis. Risk factors include poor oral hygiene, smoking, diabetes and a history of chronic periodontitis.

Codes1

D4241 - gingival flap procedure, including root planing - one to three contiguous teeth or tooth bounded spaces per quadrant
D6101 - Debridement of a peri-implant defect and surface cleaning of exposed implant surfaces, including flap entry and closure
D6102 - Debridement and osseous contouring of a peri-implant defect: includes surface cleaning of exposed implant surfaces and flap entry and closure
D6103 - Bone graft for repair of peri-implant defect - not including flap entry and closure or, when indicated, placement of a barrier membrane or biologic materials to aid in osseous regeneration
D6104 - Bone graft at time of implant placement

Clinical Policy Bulletins

By clicking on “I Accept”, I acknowledge and accept that:

  • Aetna Dental Clinical Policy Bulletins (DCPBs) are developed to assist in administering plan benefits and do not constitute dental advice. Treating providers are solely responsible for dental advice and treatment of members. Members should discuss any Dental Clinical Policy Bulletin (DCPB) related to their coverage or condition with their treating provider.
  • While the Dental Clinical Policy Bulletins (DCPBs) are developed to assist in administering plan benefits, they do not constitute a description of plan benefits. The Dental Clinical Policy Bulletins (DCPBs) describe Aetna's current determinations of whether certain services or supplies are medically necessary, based upon a review of available clinical information. Each benefit plan defines which services are covered, which are excluded, and which are subject to dollar caps or other limits. Members and their providers will need to consult the member's benefit plan to determine if there are any exclusions or other benefit limitations applicable to this service or supply. Aetna's conclusion that a particular service or supply is medically necessary does not constitute a representation or warranty that this service or supply is covered (i.e., will be paid for by Aetna). Your benefits plan determines coverage. Some plans exclude coverage for services or supplies that Aetna considers 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 or the Federal government.
  • Please note also that Dental Clinical Policy Bulletins (DCPBs) are regularly updated and are therefore subject to change.
  • Since Dental Clinical Policy Bulletins (DCPBs) can be highly technical and are designed to be used by our professional staff in making clinical determinations in connection with coverage decisions, members should review these Bulletins with their providers so they may fully understand our policies.
  • Under certain plans, if more than one service can be used to treat a covered person's dental condition, Aetna may decide to authorize coverage only for a less costly covered service provided that certain terms are met.
