Coverage Summary

Scope: This Blue Cross Blue Shield - Maine Dental Clinical Policy (Implant/Abutment Supported Fixed Prosthetics - Crowns and Fixed Partial Dentures, Guideline #06-001) defines clinical indications, required documentation, coding lists for reference, and contract-dependent exclusions and alternate benefit provisions for implant/abutment supported crowns and fixed partial dentures. Status and dates: Revised policy, publish date 01/01/2025, last review 10/29/2024. Primary accepted indications (summary): replacement of missing teeth due to accidental traumatic injury resulting in extraction/avulsion, pathologic disorders resulting in extraction, congenitally missing teeth, or congenital tooth disorders resulting in extraction. Contract-dependent exclusions/limitations (brief): services are not appropriate when teeth are not missing (including third molars); replacement of multiple teeth in the same arch by implants may be excluded when less costly acceptable alternatives exist; some plans contain a missing tooth clause or alternate benefit provisions that limit implant benefits; delivery date, benefit completeness, and other determinations are contract dependent.

Provider Actions & Workflow

Documentation Required

Preoperative evaluation and imaging

Complete a thorough dental evaluation, medical/dental history, full mouth imaging and treatment plan prior to implant placement. Provide current (within 12 months), dated, diagnostic, preoperative radiographic images. When radiographs do not clearly demonstrate necessity, include additional diagnostic information such as intra-oral photographs, patient treatment notes, and a narrative explaining extraordinary circumstances.

Required imaging: current (within 12 months) dated diagnostic preoperative radiographs.
If radiographs are inadequate: include intra-oral photos, patient treatment notes, and narrative explaining extraordinary circumstances.

Prior Authorization

Contract/plan determination

Verify the member’s contract for missing tooth clause, alternate benefit provisions, and any contract-dependent determinations regarding implant placement, restoration, and delivery date. Confirm whether third molar sites are excluded. For missing teeth resulting from accidental injury, refer claims to the subscriber’s medical plan first, as many medical plans include coverage for dental services related to accidental injury.

Coding (Informational CDT Codes)

Informational CDT Codes (implant surgical, abutment, prosthetic, repair)mixed

Informational codes are provided in the policy for reference only; inclusion of a procedure or device code does not guarantee coverage. Coverage and benefit determinations are contract dependent—providers should verify member coverage, billing allowances, and whether a given code or service is covered or non-covered with the payer prior to submission.

Background and Definitions

Background: Dental implant prosthetics restore missing teeth using implant and abutment–supported crowns or fixed partial dentures to replicate tooth structure and function. This policy provides guidance on when implant/abutment supported crowns and fixed partial dentures are appropriate, what documentation and pre-procedure evaluations are required, and notes that certain exclusions and alternate benefit provisions are contract dependent. The intent is to ensure appropriateness and adequate documentation (for example, current preoperative radiographs and a treatment plan) prior to placement and restoration. Repair and replacement, temporary/provisional restorations, metal-allergy replacements, and other special situations have additional documentation requirements or contract-dependent handling and may require detailed narratives, physician allergy documentation, or supplemental diagnostics.

Definitions:

• Delivery date: Date considered as the delivery date for implant/abutment supported crowns and fixed partial dentures is dependent on provider contract; the type of cement (permanent or temporary) does not determine the delivery date.

• Interim/provisional restoration: A temporary or provisional implant/abutment supported crown and fixed partial denture is considered inclusive with the final restoration.

Evidence summary: The policy references multiple professional society position statements and peer‑reviewed studies, including the American Dental Association CDT (2025), American Academy of Prosthodontists and American Academy of Periodontology guidance, American Association of Endodontists position statements, systematic reviews, and long‑term implant outcome studies and meta-analyses to support clinical statements and coverage considerations.

On This Page

Teeth are not missing (implant prosthetics to replace teeth that are present are not appropriate), including replacement of third molars
Replacement of multiple teeth by implant supported crowns or fixed partial dentures in the same arch when other less costly professionally acceptable dental services can adequately restore occlusion to function (not medically necessary unless specified by group contract)
Plans that contain a missing tooth clause: no benefit for replacement of missing teeth when implant/abutment supported crowns and fixed partial dentures are treatment planned; implant placement/restoration not covered for third molar sites
contract dependent
Plans with alternate benefit: where alternate benefit applies, an alternate benefit may be applied to replace all missing teeth; implant placement/restoration not covered for third molar sites (contract dependent)
contract dependent

Pre-procedure and Documentation Requirements

Covered only when ALL of the following documentation and preparatory conditions are met:

A thorough dental evaluation, medical and dental history, full mouth imaging, and treatment plan completed prior to implant placement and restoration
Current (within 12 months), dated, diagnostic, preoperative radiographic images are providedwithin 12 months
When radiographs do not clearly demonstrate necessity, additional diagnostic information must be provided (intra-oral photographs, patient treatment notes, narrative explaining extraordinary circumstances)

Special Conditions and Documentation for Specific Cases

Coverage may be considered only when specific supplemental documentation is provided:

Replacement due to metal allergy/sensitivity requires physician submission with associated allergy report
Repair and/or replacement (e.g., fractured porcelain) requires a detailed narrative (contract dependent)
contract dependent
Temporary or provisional implant/abutment supported crown and fixed partial denture are considered inclusive with the final restoration
If cement is used, type of cement (permanent or temporary) does not determine delivery date (contract dependent)
contract dependent
Delivery date of implant/abutment supported crowns and fixed partial dentures is considered the date of delivery (dependent on provider contract)
contract dependent
If subscriber does not return for delivery, there is no benefit (service considered incomplete)

Not Medically Necessary / Contraindicated

The policy specifies additional non-coverage or limited coverage situations:

Tooth-implant supported fixed partial dentures: generally not considered for benefits due to lower survival rate compared with solely implant or solely tooth supported FPDs
Implant placement may not be considered for correction of developmental or congenital defects (contract dependent)
contract dependent
Replacement of implant/abutment supported prosthetics WILL NOT be considered for closure of contacts unless prosthetics are defective
Replacement WILL NOT be considered for aesthetic reasons
For cantilever implant/abutment supported fixed partial dentures, only one cantilever pontic may be allowable benefit; peri-implant health of retainers must be considered

Check for missing tooth clause and alternate benefit provisions (contract dependent).
Confirm third molar exclusions per contract.
Refer accidental injury cases to the medical plan before dental benefit adjudication.

Billing Rule

Delivery and incompletion

Delivery date of implant/abutment supported crowns and fixed partial dentures is dependent on provider contract and is considered the date of delivery per that contract. If the subscriber does not return for delivery, there is no benefit because the service is considered incomplete. The type of cement (permanent or temporary) does not determine the delivery date (contract dependent).

Delivery date determined per provider contract.
No benefit if subscriber does not return for delivery (service incomplete).
Cement type is not determinative of delivery date.

Documentation Required

Allergy/sensitivity replacement

Replacement due to metal allergy or sensitivity will be considered only upon submission of physician documentation with the associated allergy report.

Submit physician documentation and the associated allergy report to support metal allergy/sensitivity replacements.

Denial Risk

Aesthetic and non-defective replacement

Replacement claims for aesthetic reasons or for closure of contacts (unless the implant/abutment supported prosthetic is defective) are not considered and risk denial.

Claims for aesthetic-only replacement risk denial.
Replacement to close contacts will be denied unless the prosthetic is defective.
