Coverage Criteria

Generally Accepted Indications

Covered when ANY of the following generally accepted indications is documented:

Generally accepted indication

Periodontal pocket access: Treatment of moderate to deep periodontal pockets requires access to the roots of the teeth to remove granulation tissue and debride root surfaces.
Incomplete nonsurgical debridement: Nonsurgical scaling and root planing fails to remove rough cementum and dentin and/or subgingival calculus, as judged by residual root roughness or persistent inflammation.
Diagnostic surgical access: Surgical access is required to diagnose a cracked tooth, fractured root, external root resorption, or another clinical condition requiring direct visualization.
Creation of a flap for access is part of the procedure for subsequent treatment of these conditions.

Additional Coverage Criteria

The following additional criteria may be applied depending on the individual patient's circumstances and applicable dental benefit program requirements. Unless government regulations or the member's dental plan establish different requirements, ALL of the following apply:

Additional coverage criteria

Natural teeth: The procedure is eligible for benefit coverage for treatment of natural teeth only.
Government regulations, member dental plan provisions, and program-specific criteria may take precedence.
Periodontal involvement: Periodontally involved teeth generally qualify when documented to have periodontal pocket depths and loss of attachment.At least 5 millimeter periodontal pocket depths
Loss of attachment must be documented by clinical attachment levels and/or radiographic evidence of bone loss. Plan-specific criteria may differ.
Quadrant treatment size:

Exception Review

For patients who do not meet the published qualifying criteria:

Unlisted clinical condition exception: Delta Dental of Ohio will consider documentation from relevant clinicians explaining the necessity of covering a gingival flap procedure for a condition not included in the published criteria.

Consideration does not guarantee coverage.

Coverage may be disapproved when a gingival flap procedure is performed in the absence of periodontal disease, because the clinical indication for surgical periodontal access is not established.

Coverage may be disapproved when gingival inflammation can be effectively controlled through nonsurgical periodontal treatment, including appropriate nonsurgical periodontal therapy, rather than surgical access.

Coverage may be disapproved when the procedure is performed on a tooth with a hopeless periodontal, endodontic, or structural prognosis.

Coverage may be disapproved when there is lack of or inadequate attached gingiva for the proposed periodontal procedure.

Coverage may be disapproved when osseous recontouring is not accomplished in conjunction with the gingival flap procedure, when recontouring is clinically required.

Coverage may be disapproved when the patient is noncompliant with oral hygiene procedures and supportive care.

Periodontal surgery may be considered inadvisable because of relevant medical conditions, including a history of bisphosphonate treatment or chemotherapeutic or head-and-neck radiation therapy. These circumstances may result in disapproval of benefits based on a determination that treatment is not medically necessary or clinically appropriate.

Depending on the clinical circumstances, a gingival flap procedure may be considered not medically necessary, inadvisable, or deficient in clinical quality when an exclusionary condition is present. Such circumstances may result in disapproval of benefits following a professional determination that the treatment is not medically necessary or not clinically appropriate.

Documentation and Review Requirements

Documentation Required

Medical Necessity Review

When benefit payment depends on a determination that a gingival flap procedure is medically necessary and clinically appropriate, the dental record must document a generally accepted indication and support the treatment decision. Review should be based on a thorough clinical and radiographic examination and an appropriate treatment plan.

Moderate to deep periodontal pockets requiring access to remove granulation tissue and debride root surfaces
Persistent root roughness, calculus, or inflammation after nonsurgical scaling and root planing
Surgical access needed to diagnose a cracked tooth, fractured root, external root resorption, or another condition requiring direct visualization

Documentation Required

Preoperative Radiographs Required

Submit diagnostic-quality preoperative radiographs with the claim when a gingival flap procedure is planned. Bitewing images must show the teeth in the areas where the procedure is planned.

Background

A gingival flap procedure is a surgical periodontal treatment that provides access to the roots and subgingival tissues. It may be used to remove granulation tissue and debride root surfaces when moderate to deep periodontal pockets require surgical access, or when nonsurgical scaling and root planing leaves residual root roughness, subgingival calculus, or persistent inflammation. Surgical access may also permit direct visualization to diagnose a cracked tooth, fractured root, external root resorption, or another condition requiring access to the underlying tissues.

Definitions

Gingival flap procedure

Flap elevationElevation of a mucoperiosteal flap

Tissue removalRemoval of granulation tissue to facilitate access to the roots

Root treatmentOpen scaling and root planing of the root surfaces

ClosureRepositioning and closure of the flap with sutures

Photographs should clearly depict the involved clinical areas
Include them with the claim when radiographic evidence is insufficient

Documentation Required

Periodontal Charting

Provide preoperative six-point periodontal pocket depth charting performed within 12 months of treatment. The charting must document the clinical findings needed to evaluate eligibility and appropriateness.

Document six-point periodontal pocket depths
Include clinical attachment loss
Record tooth mobility, bleeding upon probing, and furcation involvement
Complete the charting within 12 months before treatment

Documentation Required

Diagnostic Rationale and History

The patient record must explain the diagnostic rationale for performing a gingival flap procedure and include supporting information from the patient's dental and medical histories, as applicable.

Ensure the rationale is consistent with the documented examination and treatment plan
Include relevant dental-history and medical-history information

Note

Additional Clinical Information

Delta Dental of Ohio may request additional clinical information relevant to the patient's care when needed to make a medical-necessity or clinical-appropriateness coverage decision.

Respond to requests for further relevant clinical information
Provide records needed to complete the coverage evaluation

Denial Risk

Does Not Meet Qualifying Criteria

If the procedure does not meet the published qualifying criteria, benefits may be disapproved unless adequate documentation from relevant clinicians supports the necessity of treatment for a condition outside those criteria.

Document the clinical basis for any exception to the published criteria

Denial Risk

Clinical Circumstances May Make Treatment Inappropriate

Depending on the clinical circumstances, treatment may be considered not medically necessary, inadvisable, or deficient in clinical quality and benefits may be disapproved when disease status, inflammation, prognosis, treatment quality, or patient cooperation does not support the procedure.

Absence of periodontal disease
Gingival inflammation that can be effectively controlled with nonsurgical periodontal treatment
A tooth has a hopeless periodontal, endodontic, or structural prognosis
