What documentation do dental payers require for scaling and root planing (D4341 / D4342) claims?

No payer document read for this page publishes a pocket-depth threshold for scaling and root planing. Aetna's DCPB041 carries no millimetre figure at all: it asks for periodontal charting recording pocket depths at six points per tooth with bleeding on probing, unannotated full-mouth radiographs, chart notes giving the appointment duration and the type and amount of local anesthetic, and diagnostic materials demonstrating clinical attachment loss, crestal bone loss or lamina dura change, and root-surface calculus. Delta Dental Insurance requires submitted charting dated no more than 12 months before treatment, and Cigna's PERIO-16 bars payment — and any patient charge — where the same office retreats a quadrant inside 24 months. The 4 mm figure common in billing content is a literature convention the ADA disclaims: it records that payers establish their own criteria, which can differ from payer to payer and from one customer to another inside a single payer's book of business, so two similar charts under different employer group policies can be adjudicated differently. Submit the charting, the images the payer names, and quadrant tooth counts that match the code, then confirm the current rule in the linked payer document.

Scaling and root planing (D4341 / D4342) — payer documentation requirements

No payer here publishes a pocket-depth number for scaling and root planing. What each one does ask to see is below.

Deep cleaning below the gumline — D4341 for a full quadrant, D4342 for a partial quadrant. CDT codes referenced by number only.

Why these claims get denied

Payers publish detailed SRP review criteria. A claim may be denied or downcoded when the submitted periodontal charting is a screening rather than a six-point record, when it is older than the payer's window, when the required radiographic evidence is absent, or when the quadrant does not contain enough qualifying teeth.

Aetna's DCPB041 requires 6-point periodontal charting with bleeding on probing, full-mouth radiographs, and chart notes documenting appointment duration and anesthetic for scaling and root planing claims. It publishes no pocket-depth threshold: the bulletin carries no millimetre figure anywhere.

Periodontal charting that records pocket depths at 6 points per tooth, with indications of bleeding on probing
Full-mouth radiographs or digital images (unannotated/unmarked)
Chart notes documenting the duration of the appointment and the type and amount of local anesthetic administered
Diagnostic materials that demonstrate clinical loss of periodontal attachment, radiographic evidence of crestal bone loss or changes in crestal lamina dura, and radiographic evidence of root surface calculus
No pocket-depth figure: DCPB041 states no millimetre threshold for D4341/D4342, so a depth number alone neither qualifies nor disqualifies the claim

Frequency / timing: DCPB041 positions D4341/D4342 for moderate to severe periodontitis, distinct from gingivitis scaling (D4346)

Cigna

Public — no login

Cigna's scaling-and-root-planing policy is PERIO-16 in the public DPPO guidelines. The rule Dentovio has read from that document is the same-office retreatment bar: a quadrant retreated inside 24 months is not allowable, and the patient may not be charged for it.

Not allowable where retreatment of periodontal scaling is completed by the same dentist or dental office, in the same quadrant, within 24 months — and the patient is not responsible for payment
The member's own plan documents — Evidence of Coverage or Summary Plan Description — supersede these guidelines, and plan age, frequency and exclusion terms sit on top of them

Frequency / timing: Denied when the same office retreats the same quadrant within 24 months (PERIO-16)

Public — no login

Delta Dental Ins. clinical criteria require periodontal charting for scaling and root planing — D4341 and D4342 are not on the exemption list — dated no more than 12 months before the date of service. The criteria state no pocket-depth or radiographic millimetre figure for these codes.

Periodontal charting, or documentation reflecting probing depths, recession, clinical attachment loss, loss of keratinized tissue, mobility and furcation involvement, is required for periodontal procedures; the exemption list — D4230, D4231, D4249, D4346, D4355, D4910, D4920, D4921 — does not include D4341 or D4342
Submitted periodontal charting must be dated no more than 12 months prior to the date of service

Guardian's 2026 guidelines call for radiographic evidence of pathology in the supporting structures plus periodontal charting that documents findings attributable to attachment loss; D4342 applies when fewer than four teeth in a quadrant are treated.

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.

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)
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.

It contains no adult benefit rows at all, so it cannot support any statement about adults 21 and over — Texas adult dental sits outside MCNA entirely. The manual is public and carries no confidentiality marking. Every listed limit is an EPSDT floor that can be exceeded with a prior authorization documenting medical necessity, and the Medicaid and CHIP chapters carry different rules for the same codes.
