D5214 is the CDT code for a mandibular (lower arch) removable partial denture with a cast metal framework and resin denture bases. The framework is precision-cast metal, typically a cobalt-chromium alloy, and provides the clasps, rests, and connectors that anchor the prosthesis to the remaining natural lower teeth. Artificial teeth are set in resin bases attached to the framework.

Get help with D5214 claims →Patient is missing several mandibular teeth but retains enough natural teeth to serve as abutments. The cast metal framework engages these teeth for support and retention via precision-fit clasps.
When a durable removable solution is needed and fixed options (bridge or implants) are not indicated or refused. The cast metal framework offers greater longevity and stability than an all-resin partial (D5212).
D5214 requires that suitable abutment teeth exist in the lower arch. If the patient is edentulous in the mandibular arch, the correct code is D5120 (complete lower denture), not D5214.
The most common denial reason for partial denture claims. Most dental plans exclude coverage for teeth that were already missing when the patient enrolled in the plan. If the missing lower teeth predate coverage, the payer will deny D5214 on that basis. Always verify the patient's coverage start date and tooth extraction history before submitting. Review our guide on the missing tooth clause for approaches to handling this denial.
Most plans limit partial denture replacement to once every five years per arch. If the patient received a mandibular partial within the frequency window, the new D5214 claim will be denied. If early replacement is clinically justified, such as significant additional tooth loss or prosthesis failure, submit a narrative explaining the clinical necessity and include supporting radiographs.
Removable partial dentures typically require pre-authorization. Delivering the prosthesis before obtaining approval is one of the most preventable causes of non-payment. Verify pre-auth requirements before starting, submit with a panoramic or full-mouth radiograph and a list of missing teeth, and wait for written approval before beginning the case.
The clinical record must clearly support the need for a removable partial. Document the missing teeth by number, confirm abutment teeth are periodontally sound, state why a fixed prosthetic is not the chosen treatment, and describe the prosthetic design including cast metal framework. Payers increasingly scrutinize partial denture claims and may request additional records.
Shows all remaining teeth, bone levels, and the full extent of mandibular tooth loss. The primary diagnostic image used for pre-authorization review and clinical necessity determination.
Identify each missing mandibular tooth by universal number. This is what the payer uses to apply the missing tooth clause and to confirm that a partial denture is the appropriate treatment.
Document that a cast metal framework partial is the chosen prosthetic design, note the abutment teeth selected, and explain why a removable partial is indicated over fixed options.
Include probing depths or a summary statement confirming that abutment teeth have adequate bone support and are suitable for clasping. Payers may request evidence that the abutments are periodontally stable.
Record the pre-auth number, approval date, and the scope of the approval. Include the pre-auth number in the claim narrative field and keep the written approval in the patient record.

Get a free AR analysisD5214 is the CDT code for a mandibular (lower arch) removable partial denture with a cast metal framework and resin denture bases. It is used when one or more natural lower teeth remain and can support the partial's clasps and rests.
D5214 has a precision cast metal framework that provides greater strength and durability. D5212 is an all-resin mandibular partial with no cast metal component. D5214 is generally the preferred design for most long-term lower partial denture cases.
D5214 is for the mandibular (lower) arch. D5213 is for the maxillary (upper) arch. Both use cast metal frameworks with resin bases, and arch location is the only distinction between the two codes.
The most common reasons are the missing tooth clause (lower teeth were missing before coverage began), frequency limitations (partial replacement within five years), missing pre-authorization, and insufficient clinical documentation.
Most plans require pre-authorization for removable partial dentures. Verify the requirement before starting, submit pre-auth with radiographs and a missing tooth list, and wait for written approval before delivering the prosthesis.
Yes, when both arches need new cast metal partials simultaneously, D5213 and D5214 can be billed on the same claim. Each requires its own pre-authorization and documentation. Check the patient's plan for combined frequency rules that may apply to both arches.
