Fixed Partial Denture Coverage Criteria

Qualifying indications

Generally accepted indications include ANY of the following.

Generally accepted indications

Appropriate edentulous space: An edentulous space exists where a tooth-supported fixed partial denture is an appropriate choice to replace one or more missing teeth.
Unrepairable retainer defect: An existing fixed partial denture retainer has a defect that cannot be corrected by repair.
Retainer rendered unserviceable: Additional dental treatment, such as endodontic treatment of a retainer, has rendered one or more fixed partial denture retainers unserviceable.

General fixed prosthodontic coverage

Coverage under the general criteria requires ALL of the following.

General coverage requirements

Documented need for fixed appliance: A physical or neurological disorder is documented that would preclude placement of a removable prosthesis.
Oral and periodontal health: The recipient has good oral health and hygiene and good periodontal health.AAP Type I or II
Continuous deterioration should not be expected.
Favorable prognosis: The patient has a favorable prognosis for the fixed partial denture and abutment teeth.
Permanent-tooth extraction space: The edentulous space resulted from extraction within the normal complement of permanent teeth.

Clinical quality and repair criteria

Additional treatment criteria apply as clinically appropriate.

Pretreatment and treatment quality: Existing teeth and edentulous areas must be comprehensively evaluated and documented; untreated caries, failed direct restorations, periodontal disease, endodontic pathology, and structural weakness involving abutment teeth must be addressed; and the completed appliance must meet applicable standards for restorative material selection, design and preparation, marginal integrity, interproximal contacts, retention, adaptation to edentulous ridges, and occlusion.

Fixed prosthodontic services performed solely for cosmetic purposes or to adjust vertical dimension may not be covered under the member’s dental plan.

Inlay and onlay retainers, stress breakers, and precision attachments may not be covered. Fixed partial dentures performed in conjunction with a removable partial denture in the same arch and all-ceramic fixed partial dentures may also be excluded, subject to the member’s applicable plan documents.

Benefits for a covered fixed partial denture are limited to restoring edentulous spaces resulting from extractions within the normal complement of permanent teeth.

Medical necessity is not established unless documentation shows a physical or neurological disorder that precludes placement of a removable prosthesis. Fixed prosthetic appliances are considered only for these exceptional circumstances.

Coverage requires good oral health and hygiene, good periodontal health consistent with AAP Type I or II, and a favorable prognosis in which continuous deterioration is not expected.

Medical necessity is not established when an abutment tooth is supported by less than 50% bone.

Medical necessity is not established when an abutment tooth has untreated cavities or active periodontal disease. These conditions must be addressed as part of treatment before fixed prosthodontic services are considered.

A fixed partial denture may be considered unnecessary, inadvisable, or clinically deficient when the edentulous space is absent or unsuitable; there is inadequate space for a functional pontic; the pontic span or number of retainer units is excessive; abutment support, alignment, bone, or periodontal condition is inadequate; the design is an unsuitable cantilever or distal-extension indication; opposing dentition is absent; implant support is compromised; or a more appropriate alternative treatment exists.

Documentation, Billing, and Denial Risks

Documentation Required

Preoperative Abutment Radiographs

Submit preoperative radiographs demonstrating that the periodontal, endodontic, and structural condition of every abutment tooth supports placement and maintenance of the fixed partial denture. Radiographs should be obtained within 12 months of treatment and show each abutment from crown to root tip; submit an intraoral photograph when radiographic suitability is unclear.

Documentation Required

Document Clinical Rationale

Submit the patient treatment record documenting the clinical rationale for providing or replacing the fixed partial denture. Missing documentation may result in disapproval of benefit payment.

Documentation Required

Adjacent and Opposing Tooth Imaging

Submit appropriate radiographs clearly showing the adjacent and opposing teeth for authorization review or claim review, including when treatment was rendered without prior authorization.

Fixed Partial Denture Overview

A fixed partial denture is an indirectly constructed prosthodontic appliance that replaces one or more missing teeth. It generally consists of pontics suspended over an edentulous ridge and attached to retainers placed on adjacent abutment teeth. Designs may be conventional, cantilevered, or resin-bonded, with selection based on the missing-tooth space, abutment condition, opposing dentition, occlusion, periodontal and endodontic status, and structural support.

Key Prosthodontic Terms

Pontic

DefinitionA pontic is an artificial tooth unit.

PositionIt is suspended over the edentulous ridge of a missing tooth space.

AttachmentIt is attached to retainers prepared and installed on adjacent natural teeth.

Abutment tooth

DefinitionAn abutment tooth is a natural tooth prepared to receive and support a fixed partial denture retainer.

LocationAbutments are the teeth on which fixed partial denture retainers are prepared and cemented or bonded.

A crown-root ratio below 2:1 under normal occlusal forces may make the abutment unsuitable for treatment.

Abutment bone support

Minimum supportEach abutment tooth must be supported by at least 50% bone.

Coverage conditionFixed partial dentures are covered only when the abutment teeth meet the stated bone-support requirement.

Medical necessityMedical necessity is not established when abutment teeth are supported by less than 50% bone.

Periodontal health

Required classificationGood periodontal health must be documented as AAP Type I or II.

Oral healthCoverage requires good oral health and hygiene in addition to good periodontal health.

PrognosisA favorable prognosis is required, with continuous deterioration not expected.

Patient age

Age considerationPatients under age 16 are generally not appropriate for fixed partial denture placement during normal growth and maturation.

Growth concernPlacement during normal growth and maturation may require premature replacement when the dental arch reaches a mature state of equilibrium.

Alternative treatmentAn alternative treatment may be more appropriate based on the patient’s condition or circumstances.

Acceptable imaging includes bitewings, periapicals, or a panoramic radiograph.

Documentation Required

Comprehensive Pretreatment Evaluation

Before planning and performing fixed prosthodontic treatment, complete and fully document a comprehensive evaluation of the existing teeth and edentulous areas. Address untreated caries, failed direct restorations, periodontal disease, endodontic pathology, and structural weakness involving abutment teeth as part of treatment.

Billing Rule

Billing and Delivery Timing

For fixed partial dentures, report the impression date as the date of service, but do not submit the claim until the denture has been delivered to the patient. The recipient must be eligible on the delivery date for the denture service to be covered.

Documentation Required

Provide Prosthesis-Care Instructions

As part of any fixed prosthetic service, instruct the patient in the proper care of the prosthesis.

Provide proper fixed-prosthesis care instructions.

Note

Additional Clinical Information

Delta Dental of Ohio may request additional clinical information relevant to the patient's care when needed to make a coverage decision based on medical necessity or clinical appropriateness.

Denial Risk

No Generally Accepted Indication

Benefits may be denied when the record does not document a generally accepted indication for a fixed partial denture or when an appropriate edentulous space or other accepted indication is absent.

Generally accepted indications include an appropriate tooth-supported edentulous space, an unrepairable defect in an existing retainer, or additional treatment that renders a retainer unserviceable.
An alternative treatment may be more appropriate based on accepted standards of care.

Denial Risk

Unfavorable Design or Treatment Choice

Benefits may be denied when the fixed partial denture design or treatment choice is clinically unfavorable, including inadequate abutment support, an excessive pontic span or number of retainers, inadequate space, an unsupported cantilever, lack of opposing dentition, or other design deficiencies.

Other risks include a retained root remnant likely to cause complications, a severely displaced abutment that cannot be corrected, resin bonding to an existing crown, an unsuitable distal extension situation, compromised implant support, or inadequately prepared or adapted retainers.

Denial Risk

Unsuitable Abutment Teeth

Benefits may be denied when abutment teeth lack sufficient sound structure or have unresolved disease, failed restorations, inadequate root or bone support, or other deficiencies that make successful restoration unlikely.

Risk factors include caries, extensive restoration or fracture; unresolved periapical pathology or failed endodontic treatment; improper post alignment; root fracture or resorption; advanced furcation or mucogingival defects; a crown-root ratio below 2:1 under normal occlusal forces; primary teeth undergoing exfoliation; or insufficient healing after crown lengthening.

Denial Risk

Poor Oral or Periodontal Condition

Coverage is limited to patients with good oral health and hygiene, good periodontal health, and a favorable prognosis. Denial risk increases when poor hygiene, high caries risk, untreated cavities, active periodontal disease, inadequate bone support, or other conditions make continued deterioration or treatment complications likely.

Fixed partial dentures are covered only for recipients with good periodontal health (AAP Type I or II) and a favorable prognosis.
Medical necessity criteria also require documentation of a physical or neurological disorder precluding placement of a removable prosthesis in exceptional cases; abutment teeth with less than 50% bone support do not meet the criteria.

Denial Risk

Plan Exclusions and Noncovered Purposes

Review the member's plan before treatment because certain fixed prosthodontic services or purposes may be excluded or noncovered. Government requirements and plan provisions may take precedence over these clinical criteria.

Noncovered or excluded purposes may include treatment solely for cosmetic purposes or vertical-dimension adjustment, inlay or onlay retainers, stress breakers, precision attachments, fixed partial dentures used with a removable partial denture in the same arch, and all-ceramic fixed partial dentures.
Fixed prosthetic appliances are generally considered only in exceptional cases involving a documented physical or neurological disorder that precludes a removable prosthesis; prosthetic services are intended to restore form and function after premature loss of permanent teeth causing significant occlusal dysfunction.

The condition of the abutment teeth is considered when designing a fixed partial denture.

Retainer

DefinitionA retainer is a component prepared and installed on an adjacent natural tooth to support and attach the pontic unit.

PlacementRetainers are placed on adjacent natural teeth.

Common formFixed partial dentures typically utilize crowns as retainer units.

Conventional fixed partial denture

Pontic requirementA conventional fixed partial denture has at least one pontic filling a missing tooth space.

Retainer requirementIt has two abutment tooth retainers attached on either side of the pontic unit.

SupportThe two retainers support the pontic unit.

Cantilever bridge

Support configurationA cantilever bridge has a pontic supported by a retainer on only one abutment tooth.

Pontic positionThe pontic is cantilevered from the retainer unit.

Distinguishing featureUnlike a conventional fixed partial denture, the design uses a single abutment tooth rather than retainers on both sides of the pontic.

Bonded bridge

DefinitionA bonded bridge is a minimally invasive alternative to a conventional fixed partial denture.

Retention methodIt is secured to abutment teeth by retainer wings attached to their lingual surfaces using resin bonding.

Typical candidacyIt may be considered when abutment teeth are intact, the missing-tooth space has no significant soft-tissue defect, and pontic occlusal forces will not be excessive.
