Dentovio is an independent publisher — not a dental payer, the ADA, or any state dental board. This page was drafted with AI assistance and verified against the primary sources linked here. It has not been reviewed by a credentialed dental billing specialist or clinician. These summaries describe the payers' published clinical-review and documentation criteria as addressed to dentists — what a reviewer looks for on a claim, never what a patient's plan pays. Individual plan contracts govern: every payer document here states that the member's plan documents control coverage, frequencies and exclusions where they conflict with the policy, and payers revise policy documents on their own schedules. Where a record's reach is narrower than the payer — one plan line, one federal program, one state Medicaid program — or where a figure comes from a plan-sponsor or federal-program document rather than the payer's own policy manual, the record says so. Educational billing reference only, not billing, legal, or clinical advice. CDT codes are referenced by number only; CDT is the American Dental Association's copyrighted code set and this page does not reproduce ADA descriptors.

## Direct answer

For osseous surgery the published payer criteria are documentary and temporal rather than numeric. Delta Dental Insurance requires that the procedure include removal of supporting bone (ostectomy) and/or non-supporting bone (osteoplasty) with elevation of a full-thickness flap and closure, plus periodontal charting within 12 months. Guardian applies a generic periodontal-surgical-services standard — radiographs showing pathologic loss of alveolar crest height, periodontal charting, and exclusion of any tooth with 50% or more bone loss for poor prognosis. Aetna's DCPB012 states no pocket-depth, bone-loss, or prior-scaling requirement at all, and limits the benefit typically to one pocket-reduction surgery per quadrant or tooth in any 36 consecutive months. Cigna's office reference guide bars payment and any patient charge for same-office retreatment of a quadrant within 36 months, and United Concordia denies the claim as misreported where the quadrant does not show periodontal disease with moderate-to-deep pockets. Medicaid programs add age bands, prior authorization, and their own frequency caps.

## Why these claims get denied

Osseous-surgery claims fail on evidence and timing: charting or radiographs that do not show the disease the payer expects in the reported quadrant, a procedure that does not meet the payer's definition of osseous surgery, or a retreatment inside the payer's retreatment window.

## Requirements by payer

### Aetna

Aetna's DCPB012 classifies pocket-reduction surgery as dental-in-nature oral surgery and states no pocket-depth, bone-loss, or prior-therapy criterion; the published limit is typically one pocket-reduction surgery per quadrant or tooth in any 36 consecutive months.

- Aetna treats the pocket-reduction codes as dental-in-nature oral surgery, coverable under either a medical or a dental plan
- In dental plans that cover these periodontal services, the benefit is typically limited to one type of pocket-reduction surgery per quadrant or tooth in any 36 consecutive months — a cap shared across all pocket-reduction procedures, not one per code
- The bulletin publishes no pocket-depth number, no radiographic bone-loss requirement, and no prior-scaling requirement for D4260 or D4261; Dentovio read the full bulletin on 2026-08-30 to confirm that absence
- LANAP is not considered osseous surgery; where it meets Aetna's clinical guidelines for necessity it is benefited at the scaling-and-root-planing level
- Frequency / timing: Typically one pocket-reduction surgery per quadrant or tooth in any 36 consecutive months, and only in plans that cover these periodontal services.

### Cigna

Osseous surgery has its own named public policy in Cigna's DPPO guidelines, and the office reference guide bars both payment and any patient charge for same-office retreatment of a quadrant within 36 months.

- Osseous surgery is covered by a named policy in the public DPPO guidelines (PERIO-06, D4260/D4261) — none of Cigna's periodontal criteria are portal-gated
- The office reference guide lists retreatment of surgical periodontal services on the same quadrant within 36 months by the same dentist or dental office among the services for which there is no payment and no charge to the patient
- Frequency / timing: No payment and no patient charge for same-office retreatment of surgical periodontal services on the same quadrant within 36 months.

### Delta Dental (Delta Dental Ins. enterprise)

Delta Dental Ins. defines osseous surgery by what the procedure must include — bone removal plus a full-thickness flap and direct reshaping of the alveolar process — and requires periodontal charting within 12 months.

- The procedure must include the removal of supporting bone (ostectomy) and/or non-supporting bone (osteoplasty)
- Procedures that do not include elevation of a full-thickness flap and closure, and direct surgical modification and reshaping of the bony support, do not qualify as osseous surgery
- The submission table requires periodontal charting (probing) completed within the past 12 months for the periodontal surgical codes
- For bone replacement grafts, benefits are generally allowable on vertical, multi-walled or narrow defects, and may not be allowed in areas of horizontal bone loss, class III furcation involvements, and broad interproximal defects
- Grafts are not covered benefits when performed in conjunction with extractions, mucogingival surgery, periradicular surgery, implants, or ridge augmentation

### United Concordia

United Concordia denies osseous surgery as misreported where a dental advisor finds the reported quadrant does not show periodontal disease with moderate-to-deep pockets, evidenced by radiographic bone loss.

- The claim is denied as misreported where a dental advisor determines that the teeth in the reported quadrant do not show the presence of periodontal disease with moderate-to-deep pocket depths necessitating reshaping of the alveolar process, as evidenced by radiographic bone loss
- Under the 2025 FEDVIP brochure the federal plan allows one periodontal surgical procedure per 24 months per area of the mouth
- Scope: The first rule is from United Concordia's public PPO clinical policy; the frequency rule is the 2025 FEDVIP brochure and applies to that federal plan only.

### Guardian

Guardian publishes no code-specific osseous-surgery entry; a generic periodontal-surgical-services block applies, keyed to radiographic crest-height loss and charting, with any tooth at 50% or more bone loss excluded for poor prognosis.

- There is no code-specific osseous-surgery entry in the public guidelines; a generic periodontal-surgical-services criteria block governs the surgical periodontal codes
- Benefit may only be allowed with documentation of periodontal disease evidenced in radiographs and periodontal charting
- Radiographs must show pathologic loss of alveolar crest height from the cementoenamel junction to the adjacent alveolar bone
- Any tooth with 50% or more bone loss is excluded for poor periodontal prognosis
- Radiographs must be pre-operative and taken within 24 consecutive months of the date of service and labelled with side, patient name, date and provider; periodontal charting must be within 12 months, and a panoramic radiograph alone is considered to have limited diagnostic value outside oral surgery
- Published threshold: Radiographic pathologic loss of alveolar crest height from the CEJ; a tooth at 50% or more bone loss is excluded for poor prognosis.

## Other payer records without an extracted rule for this procedure

An absent record here does not mean the payer has no policy. It means Dentovio has not extracted a rule for this procedure from that payer's material — and in several cases a verifier read the payer's public criteria in full and found no entry for the code, which is recorded in that payer's notes rather than invented as a rule.

- Delta Dental of New Jersey: Public — no login. Delta Dental of New Jersey is a separate member company from the Delta Dental Insurance enterprise recorded above — do not read one company's criteria onto the other. The handbook edition Dentovio read is the 2023 participating-dentist edition; confirm a newer edition before relying on it, and confirm the group's own contract, which the handbook says can vary. Policy library: [Delta Dental of New Jersey Participating Dentist Handbook, 2023 edition (PDF)](https://www.deltadentalnj.com/-/media/DDNJ/Handbook/Delta_Dental_NJ_Participating_Dentist_Handbook.ashx)
- Delta Dental of Arkansas (Delta Dental Smiles, Arkansas Medicaid): Public — no login. This record covers Arkansas Medicaid only and is a different member company from the two Delta Dental records above. The manual carries no confidentiality marking. Children's and adult exclusion wording differ in places and must not be quoted for one another. Policy library: [Delta Dental Smiles Provider Manual V12, Delta Dental of Arkansas (PDF)](https://www.deltadentalar.com/docs/default-source/smiles-provider-resources/smiles-provider-manual-r12.pdf)
- MetLife: Provider portal login required. MetLife is the one payer here whose criteria Dentovio cannot read: the provider portal is credential-gated and the official public copy of the resource manual was unavailable on every attempt, so no scaling, crown or post-and-core rule is published under MetLife's name here. The one record that exists comes from a plan sponsor's summary plan description, not from MetLife's own policy library, and is scoped that way. An absent MetLife record means Dentovio could not read the document, never that MetLife has no rule.
