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
