From policy not-indicated list

inv-08: Coverage when surgery is clinically indicated

Covered when ALL of the following are met

General coverage criteria: Non-surgical periodontal therapy has been attempted or judged insufficient and surgical intervention is required to eliminate periodontal pockets, recontour osseous bone, or expose/lengthen the clinical crown for restorative procedures.

Supported by evidence showing greater PPD reduction and CAL gain for pockets >=6 mm

Clinical measurement context: Sites with probing pocket depths >=6 mm (noting greater benefit and regenerative gains in sites >8 mm).>=6 mm

Meta-analysis: 0.6 mm more PPD reduction at 12 months for surgical vs non-surgical in pockets >=6 mm.

Gingivectomy and gingivoplasty are surgical soft-tissue procedures intended to remove or reshape gingiva to eliminate suprabony pockets and manage soft-tissue overgrowth. These procedures are not indicated when underlying bone surgery is required to treat an infrabony defect or to evaluate bone morphology, because gingival resection alone will not address the osseous pathology. They are also not indicated when the bottom of the periodontal pocket is apical to the mucogingival junction, or in anatomic situations (for example, a shallow palatal vault or a prominent external oblique ridge) where gingival resection cannot achieve the intended therapeutic outcome.

Resective periodontal surgical procedures are not indicated in individuals with an unmanaged medical condition that adversely affects wound healing. Examples of such conditions include, but are not limited to, metabolic disorders, significant cardiovascular disease, autoimmune or inflammatory diseases, and genetic conditions that impair collagen synthesis. When a patient has an active, uncontrolled systemic condition that increases the risk of poor healing or infection, surgical therapy should be deferred until the condition is medically managed and the risk is reduced.

Resective periodontal surgical procedures are not indicated for individuals taking medications that negatively affect the healing response. Examples include, but are not limited to, immunosuppressive agents, systemic corticosteroids, anticoagulants, nonsteroidal anti-inflammatory drugs (NSAIDs), and nicotine use. If medication-related impairment of healing cannot be mitigated (for example, by coordinating temporary modification of therapy with the prescribing clinician), surgical intervention is generally contraindicated.

Gingivectomy and other resective soft-tissue procedures are considered not medically necessary in situations listed as not indicated: when bone surgery is required to address infrabony defects or examine bone morphology; when the pocket base is apical to the mucogingival junction; in anatomic areas where the procedure cannot achieve its objective (eg, shallow palatal vault, prominent external oblique ridge); for teeth with a hopeless prognosis; for patients non-compliant with non-surgical therapy; or when the patient has unmanaged medical conditions or is taking medications that impair healing.

Services lacking adequate clinical documentation to demonstrate that the criteria for medical necessity are met, or services that are not supported by the member's specific benefit plan, may be deemed not medically necessary or non-covered. Listing of a procedure code in this policy is for reference only and does not guarantee coverage or payment; benefit determination is governed by the member-specific benefit plan document and applicable laws. Providers should include clinical measures (probing depths, attachment levels, prior non-surgical therapy attempts) and relevant medical history to substantiate the need for resective periodontal surgery.

Background on Resective Periodontal Surgical Procedures

Resective periodontal surgeries (including gingivectomy/gingivoplasty, gingival flap and apically positioned flap procedures, osseous surgery, clinical crown lengthening, and mesial/distal wedge procedures) are performed to eliminate periodontal pockets, remove fibrotic or enlarged gingiva, expose teeth for restorative treatment, and recontour bone and soft tissue to achieve physiologic form and facilitate long-term periodontal health. Indications vary by procedure but commonly include persistent probing depths and loss of attachment despite appropriate non-surgical therapy, the need for improved access to root surfaces or bone, and the requirement to expose or lengthen clinical crown for restorative procedures. Osseous surgery is reserved for patients with more advanced disease (for example, Stage III or IV) when less invasive measures have failed and recontouring of alveolar bone is necessary to reestablish a maintainable periodontal environment.
