What documentation do dental payers require for periodontal maintenance (D4910) claims?

Periodontal maintenance is adjudicated on treatment history and plan frequency, and the published rules differ by payer. Cigna's PERIO-20 allows it where there is a history of active periodontal therapy — D4210/D4211, D4240/D4241, D4260/D4261, or D4341/D4342 — or of a previously allowed maintenance visit, and states that plan frequency limitations may apply rather than publishing an interval. Aetna publishes no clinical policy bulletin on D4910 at all; its DMO plans cover it twice a year only with a history of periodontal surgery, with prior scaling and root planing qualifying since April 1, 2023, and a prophylaxis allowance otherwise. United Concordia's 2025 federal FEDVIP plan allows four combined cleanings a calendar year, five for members registered with a listed condition or pregnancy. Delta Dental Insurance expressly exempts maintenance from its 12-month periodontal-charting requirement, and MCNA's Texas children's program pays it once per 12 calendar months for ages 13 to 20 after active therapy.

Periodontal maintenance (D4910) — payer documentation requirements

Payers gate periodontal maintenance on what came before it, not on attachments. Each payer's published history and frequency rule is below.

The recurring upkeep visit after active gum treatment, billed instead of a routine cleaning. CDT codes referenced by number only.

Why these claims get denied

Periodontal maintenance is denied on history and frequency rather than attachments. Payers ask what active periodontal therapy preceded the visit, how many maintenance visits the plan allows in the year, and whether the visit should have been billed as a routine prophylaxis instead.

Aetna

Public — no login

Aetna publishes no clinical policy bulletin on periodontal maintenance; its concrete public D4910 rules are DMO-plan-specific — twice a year with a history of periodontal surgery, and a prophylaxis allowance when there is none.

Scope: Aetna DMO/PCD plans plus the 2025 OPM FEDVIP brochure. Aetna publishes no commercial-wide D4910 rule.

None of Aetna's 44 Dental Clinical Policy Bulletins covers periodontal maintenance; the public D4910 rules sit in the DMO/PCD Dental Office Guide and the claim-documentation guidelines instead
On DMO plans, periodontal maintenance is covered twice per year only where there is a history of periodontal surgery
Effective April 1, 2023, D4341 and D4342 were added to the DMO list of procedure codes that allow a future D4910
With no history of periodontal surgery, an allowance for a routine prophylaxis (D1110) applies instead, provided the plan's prophylaxis frequency of two per year — six per year on pre-1991 plans — has not been met
The claim-documentation guidelines state that a periodontal maintenance visit by definition also includes site-specific scaling and root planing for any number of teeth
Under the 2025 OPM FEDVIP brochure, Aetna's federal dental plan limits D4910 to twice per calendar year
No prior-therapy lookback window appears in any of Aetna's public material on this code; a verifier searched the bulletin index, the periodontal bulletins, the claim-documentation guidelines and the DMO guide on 2026-08-30 to confirm that absence rather than infer one

Frequency / timing: DMO plans: twice per year with a history of periodontal surgery. FEDVIP 2025: twice per calendar year. Neither figure describes Aetna's commercial employer-group plans.

Cigna

Public — no login

Cigna's PERIO-20 allows periodontal maintenance where there is a history of active periodontal therapy or of a previously allowed D4910, and leaves frequency entirely to the member's plan.

Allowable where there is a history of active periodontal therapy — D4210/D4211, D4240/D4241, D4260/D4261, or D4341/D4342 — or a history of a previously allowed periodontal maintenance visit
Not allowable where there is no history of active periodontal therapy
Where it is submitted with a routine prophylaxis or full-mouth scaling on the same date of service, or within the same calendar or policy year, plan guidelines may apply
Cigna publishes no periodontal-maintenance interval; the policy states that plan frequency limitations may apply. The only 24-month rule in the periodontal section is same-office retreatment of scaling and root planing, not maintenance

Frequency / timing: None published. Plan frequency limitations may apply.

Delta Dental (Delta Dental Ins. enterprise)

Public — no login

Delta Dental Ins. expressly exempts periodontal maintenance from the periodontal-charting submission requirement, and its clinical criteria state no maintenance eligibility rule and no prior-therapy lookback at all.

Periodontal charting is required for periodontal procedures generally, but periodontal maintenance is on the express exemption list alongside D4230, D4231, D4249, D4346, D4355, D4920 and D4921
Where charting is required, submitted charting must be dated no more than 12 months before the date of service
The clinical criteria state no maintenance eligibility rule and no 24- or 36-month prior-therapy lookback; Dentovio read the full 23-page document on 2026-08-30 to confirm that absence

United Concordia

Public — no login

United Concordia's federal FEDVIP plan runs a combined cleaning cap — four periodontal and two routine cleanings a calendar year, not exceeding four in total — with one extra maintenance visit for members registered with a listed condition or pregnancy.

Scope: The 2025 OPM FEDVIP plan year only — federal-program plan terms, not United Concordia's commercial or Medicaid criteria.

The 2025 FEDVIP brochure limits the plan to four periodontal cleanings and two routine cleanings within a calendar year period, with the total not exceeding four in a calendar year
The plan's wellness benefit allows one additional periodontal maintenance visit — five in total — for members with diabetes, heart disease, cerebrovascular disease (stroke), oral cancer, lupus, an organ transplant, or rheumatoid arthritis; pregnancy carries the same enhanced benefit
Members with those conditions must be registered in the plan's member portal before receiving services for the additional visit to apply
The brochure states no prior-active-therapy prerequisite for periodontal maintenance; Dentovio searched the full brochure on 2026-08-30 to confirm that absence

Frequency / timing: Four combined cleanings per calendar year, or five with a registered qualifying condition or pregnancy.

Limited to once per 12 calendar months
Covered for ages 13 to 20 only
Prior authorization or claim documentation, x-rays and documented medical necessity are required — coverage is conditional, not routine
The CHIP schedule is a separate chapter and carries no periodontal-maintenance row at all

Frequency / timing: Once per 12 calendar months, ages 13 to 20.

Other payer records without an extracted rule for this procedure

An absent record 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 below 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.

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. Delta Dental Smiles Provider Manual V12, Delta Dental of Arkansas (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. MetLife dental provider portal (current criteria; single sign-on required)
Guardian — Public — no login. Guardian publishes these criteria without a login, and the guidelines carry no confidentiality marking. Individual plan provisions still control benefits: every section states that clinical guidelines are subject to individual consideration by Guardian's dentist consultants and that individual plans may vary. The public 2026 guidelines contain no periodontal-maintenance, full-mouth-debridement, localized-antimicrobial, implant, or removable-prosthodontics entry — Dentovio read all 13 pages on 2026-08-30 to confirm those absences rather than infer them. Replacement intervals are not in the clinical guidelines at all; they are in the network dentist manual. Guardian provider toolkit — public clinical-guidelines link
DentaQuest (Medicaid/CHIP administrator) — Public — no login. Medicaid programs also apply the state's own criteria (for example TMHP in Texas). For members under 21, federal EPSDT coverage rules apply on top of the ORM, and requests to exceed a listed limit can be prior authorized with documentation of medical necessity. Three distinctions decide whether a rule applies to your patient: the member subgroup (child, adult state plan, or IDD waiver), the review type (prior authorization, post-treatment pre-payment review, or none), and the state. DentaQuest's office reference manuals stamp themselves proprietary and confidential despite being publicly hosted, so Dentovio paraphrases and links rather than reproducing their tables.
