Blue Cross Blue Shield WI mucogingival surgery Coverage

Coverage and Medical Necessity Criteria

Medical Necessity Criteria

Covered when ALL of the following are met unless extraordinary circumstances exist:

Documentation prerequisites: Provide current (within 12 months) dated pretreatment periodontal chart documenting millimeters of recession (CEJ to gingival margin), millimeters of attached gingiva remaining, 6-point pocket depth measurements; history of progressive recession within the prior 12 months; notation of high frenum attachments; number of teeth affected; photographic documentation of areas demonstrating recession may be required; current (within 12 months) pretreatment radiographs may be required dependent on prior dental history; indicate root sensitivity and relationship to cervical caries/existing restorations; include a narrative stating the rationale for the procedure.

Supports necessity, site selection, and prior authorization diagnostics

Anatomic thresholds: Periodontal charting indicates minimum 2 millimeters of keratinized gingival tissue recession and 1 millimeter or less of attached gingiva remaining, unless extraordinary circumstances (e.g., frenum involvement or chronic inflammation) apply.keratinized recession >=2 mm AND attached gingiva <=1 mm

Exception allowed for extraordinary circumstances

Acceptable clinical indications: Progressive gingival recession with loss of attached gingiva and root exposure; absence or reduction of keratinized attached gingiva; pocket depth extending beyond the mucogingival junction; high frenum attachments; inadequate vestibular depth; chronic marginal inflammation; root sensitivity.

Procedure may be considered for tooth, implant, or edentulous tooth position

Exclusions and limitations: Procedures performed solely for cosmetic purposes are not benefitted; biologic dermal matrix materials are not benefitted when submitted in conjunction with soft tissue grafting; benefits are generally limited to one periodontal surgical procedure in a 36/60 month period per single tooth or multiple teeth in the same quadrant (group contract dependent); frenectomy/frenuloplasty is considered inclusive when performed on the same date and in the same area as a soft tissue graft.

Crown-to-root ratios poorer than 1:1 may lead to denial

Mucogingival surgery and soft tissue grafting are covered only when the documented clinical criteria are met and the procedure is not solely for esthetic purposes. Procedures performed solely for cosmetic purposes are not benefitted. Additionally, when biologic dermal matrix materials are submitted in conjunction with soft tissue grafting, those biologic dermal matrix materials are not benefitted under this policy.

Benefits and allowable frequency are group contract dependent; generally, coverage is limited to one periodontal surgical procedure in a 36/60 month period per single tooth or multiple teeth in the same quadrant. When implants are involved, additional procedures will be assessed based on submitted diagnostics, narrative/rationale and photographs to establish necessity and appropriateness.

Mucogingival surgery and soft tissue grafting are inappropriate and therefore not necessary when the patient demonstrates good oral health with maintained plaque control (no plaque buildup). Clinical studies indicate that when plaque control is maintained there may be no minimum width of keratinized gingiva required to prevent periodontal disease.

Conversely, when considering grafting, the policy requires documentation of progressive recession or other clinical indications. In the absence of extraordinary circumstances such as frenum involvement or chronic inflammation, grafting will only be considered when periodontal charting documents a minimum of 2 millimeters of keratinized gingival tissue recession and 1 millimeter or less of attached gingiva remaining.

Soft tissue grafting may be inappropriate for teeth with a poor prognosis related to unfavorable anatomy; specifically, grafts performed on teeth with a crown-to-root ratio poorer than 1:1 may be denied.

Prior Authorization, Documentation, and Billing Guidance

Prior Authorization

Prior authorization and diagnostics recommended

Prior authorization is recommended for mucogingival surgery and soft tissue grafting. Submit current (within 12 months) pretreatment periodontal charting, photographic documentation and a narrative rationale to establish medical necessity. Pretreatment radiographs may be required depending on prior dental history. Include documentation of progressive recession, number of teeth affected, presence of high frenum attachments, indication of root sensitivity, and relationship to cervical caries or existing restorations.

Current (<= 12 months) dated pretreatment periodontal chart with: millimeters of recession (CEJ to gingival margin); millimeters of attached gingiva remaining; pocket depth measurements (6-point per tooth).
Photographic documentation of recession areas (may be required).
Current (<= 12 months) pretreatment radiographs (may be required depending on history).
Narrative stating rationale for the procedure and indication of progressive recession within prior 12 months.
Notation of high frenum attachments and number of teeth affected.

Background and Clinical Context

Mucogingival surgery and soft tissue grafting are periodontal surgical procedures performed to address conditions such as gingival recession, inadequate keratinized attached gingiva, high frenum attachments, and inadequate vestibular depth. The goals of these procedures include improving function, reducing root sensitivity, covering exposed root surfaces, and restoring a natural gingival margin.

Soft tissue grafting commonly uses autogenous donor tissue (for example, from the palate) or tissue from a tissue bank and includes techniques such as connective tissue grafts, free gingival grafts, pedicle grafts, and combined connective tissue and pedicle grafts. Free gingival grafts may also be used to deepen the vestibule or eliminate frenum pulls.

Definitions and Graft Types

Definition of soft tissue grafting

PurposeObtain and attach soft tissue to areas of gum recession to thicken and reinforce gum tissue

Clinical goalsCover exposed root surfaces and restore a more natural gumline

Additional benefitsReduce tooth sensitivity, protect root surfaces from decay and further recession, and improve periodontal health and aesthetics
