Fixed Partial Denture

A fixed partial denture, commonly called a bridge, is a prosthetic appliance permanently cemented onto prepared natural teeth or implant abutments to replace one or more missing teeth. The prosthesis consists of retainer crowns (placed over the abutment teeth on either side of the gap) and one or more pontics (the artificial teeth that fill the edentulous space). Unlike removable partial dentures, a fixed partial denture cannot be taken out by the patient and functions much like natural teeth for chewing and speech.

Billing for a fixed partial denture requires coding each component individually. Retainer crowns are coded based on the material used, such as D6750 for a metal crown retainer, D6751 for a porcelain-fused-to-predominantly-base-metal retainer, or D6752 for porcelain-fused-to-noble-metal. Pontics follow a parallel coding structure under the D6200 series, again differentiated by material. A three-unit bridge generates three separate line items on the claim, and a five-unit bridge generates five. Errors in unit reporting, incorrect material codes, or failure to specify the tooth numbers for each component are among the most common reasons for claim rejection on fixed prosthodontic cases. Practices should also verify whether the patient's plan includes a missing tooth clause, which excludes coverage for replacing teeth that were lost before the insurance effective date.

When managing the revenue cycle, fixed partial dentures represent significant case value, often ranging from several thousand dollars per case. Pre-authorization is strongly recommended, as most insurance plans classify bridges under major restorative benefits with 50% coverage and may apply waiting periods. Collecting the patient's estimated portion before or at the time of cementation helps practices avoid large outstanding balances. Additionally, practices should track the five-to-ten-year replacement frequency limitations that many plans impose on fixed prosthodontics, as submitting a claim within the replacement window results in automatic denial. Proactive verification of these plan details before initiating treatment protects both the practice's revenue and the patient's financial expectations.
