Subject: Soft Tissue Graft Procedures 

Reviewed: September 5, 2007

Important Note

This Clinical Policy Bulletin expresses Aetna's determination of whether certain services or supplies are medically necessary. We have reached these conclusions based upon 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, and 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 eligible, which are excluded and which are subject to dollar caps or other limits. Members and their dentists will need to consult the member's benefits plan to determine if there are any exclusions or other benefits limitations applicable to this service or supply. The conclusion that a particular service or supply is medically necessary does not constitute a representation or warranty 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 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, the federal government or CMS for Medicare and Medicaid members.

Policy

Aetna considers these surgical procedures to be dental-in-nature (DIN) oral surgery.  Coverage may be available for DIN oral surgery procedures under either medical or dental plans.

Background

Soft tissue grafts, including pedicle grafts, free gingival grafts, subepithelial connective tissue grafts and combination procedures, are surgical procedures designed to increase the zone of keratinized tissue around the tooth root, deepen the vestibule or eliminate prominent frenum involvements. These procedures are performed to stop progressive recession and/or to provide gingival coverage over sensitive root surfaces.

Soft tissue defects include, but are not limited to, dehiscences, fenestrations and inadequate gingival margins. Defects can occur in areas with minimal pocket depth and are generally localized to either the facial or lingual tooth surfaces. Typically, there is very little or no interproximal bone loss associated with these defects, and the defects are usually restricted to the same vestibular surfaces.

Pocket depth measurements and radiographs cannot adequately demonstrate facial or lingual soft tissue loss and have minimal diagnostic value in documenting this pathosis.
