D2971 frequency and documentation

D2971 (Additional procedures to construct new crown under existing partial denture framework) — frequency/coverage triggers: May be denied when submitted more than once for the same site within applicable restorative timing rules; provide pre-op periapical x‑ray and narrative. Dentist should verify benefits before treatment.

• Affected code: D2971
• Provide documentation: pre-op periapical x‑ray, detailed narrative

Denture adjustment / rebase / reline frequency

Denture adjustments, rebases and relines — frequency denial risk: Adjustments, reline/rebase or repairs are covered only for six months following delivery of a denture. Subsequent adjustments/relines/rebases outside frequency limits may be denied and become member liability.

• Covered adjustments/reline/rebase/repairs: within 6 months of delivery
• Replacement or additional adjustments after this period: may be denied

Restoration replacement timing denials

Restoration replacement timing — replacement of crowns/onlays has a five‑year limitation. Replacement before the five‑year time period may be denied as a replacement and could be member liability unless clinical necessity is documented.

• Onlay or crown: one per tooth in a five‑year period

Cosmetic-only crown/related procedure denials

Anatomical crown exposure and related procedures (e.g., crown lengthening when performed solely for cosmetic reasons) are not covered. Crown placement for cosmetic reasons (including peg laterals) may be denied; document clinical necessity.

• Document clinical justification and radiographs if restoration is restorative rather than cosmetic

D3432 / biologic materials — coverage note

• Cosmetic restorations: document clinical indications to request review

Replacement denial risk — prosthetics and abutment support

Replacement denials — replacement of prosthetics (crowns, bridges, abutment‑supported retainers) may be denied if within contractual timeframes or if inadequate abutment support exists. Dentist Advisor may deny entire bridge for inadequate abutments.

• Replacement of abutment‑supported retainer/retainer crowns may be denied if within time limits or lacking abutment support
• Dentist Advisor can deny bridge if crown/root ratio or support inadequate

Rebase / reline frequency risk

Rebase/reline frequency denial risk: Relines and rebases are considered part of denture benefit sequence and are limited; repeated rebases/reline beyond allowed frequency may be denied as member liability.

• Rebase/reline covered within 6 months of delivery; thereafter may be denied
• Document delivery date (insertion) to establish coverage window

Age-based coverage exceptions and denial risk

Age-based denial risk: Certain procedures (e.g., crowns on primary teeth) are generally not covered except in specific situations such as retained primary tooth without permanent successor — these require Dentist Advisor review and documentation of periodontal support.

Dentist Advisor review — inadequate abutment support

Dentist Advisor denial risk for inadequate abutment support: Bridges/pontics may be denied if abutment teeth lack adequate support (crown/root ratio, bone loss, mobility); submit full mouth periapical x‑rays and periodontal charting for review.

• Dentist Advisor may deny entire bridge for inadequate abutment support
• Required docs: pre-op periapical x‑rays of entire treatment site, periodontal charting, narrative

D9120 — FPD sectioning billing considerations

D9120 (Fixed partial denture sectioning) — billing and integration: sectioning may be considered integral to other FPD services or subject to review; document operative necessity and timing to avoid denial.

• D9120 may be reviewed for integration with major prosthetic services
• Provide narrative justification when billed separately

D4355 integral procedure billing restriction

D4355 (Full mouth debridement) — may be denied as integral if performed same day and same dentist as prophylaxis (D1110) or scaling and root planing (D4341/D4342). A participating dentist may not bill the member when considered integral.

• Dentist may not bill member when integral

GTR / biologic materials — non‑coverage and member liability

GTR denial/member liability triggers: When GTR or biologic materials are billed in conjunction with certain endodontic surgical procedures (periradicular surgery), these codes (D3428–D3431) are not covered and are member liability. Dentist Advisor review cannot overturn non‑coverage unless contractually specified.

• Not covered with periradicular surgery: D3428, D3429, D3431
• Member liability applies; supply x‑rays but expect non‑coverage

Not covered / integral with extractions and RCT timing

Integral procedure — billing and denial guidance

Integral procedure billing restriction: When a procedure is considered integral to a more comprehensive procedure performed the same date by the same dentist (e.g., D4212 to restorative, D4355 with prophylaxis, reline/repairs with denture delivery), the integral procedure is not separately payable and a participating dentist may not bill the member.

• Common integral pairs: D4212 with restorative procedure, D4355 with D1110/D4341/D4342, denture repairs within 6 months of delivery
