D5211 is the CDT code for a maxillary (upper arch) removable partial denture with a resin base. The full descriptor is: maxillary partial denture, resin base (including retentive/clasping materials, rests, and teeth). This partial has no cast metal framework. Clasping and retentive elements are incorporated into the acrylic resin base rather than a separate precision-cast metal skeleton.

Get help with D5211 claims →When the clinical situation does not require the rigidity of a cast metal framework, or when the patient has a documented metal allergy, a resin-base partial (D5211) is the appropriate choice for the upper arch.
Patient is missing upper teeth but retains natural teeth to serve as abutments for the retentive clasping elements. The resin base wraps around abutment teeth to provide retention without a separate metal skeleton.
D5211 may be used when additional teeth may be lost and the dentist wants a prosthetic that is easily modified. Resin-base partials are simpler to reline or add teeth to compared to cast metal partials.
The missing tooth clause is the leading denial reason for all partial denture codes. Most dental plans exclude coverage for any tooth that was already missing when the patient's insurance coverage started. Before submitting D5211, verify the patient's coverage effective date and compare it to extraction dates in the record. If all missing teeth predate coverage, expect a denial. Our guide on the missing tooth clause explains how this clause works and how to respond to these denials.
Most plans limit partial denture replacement to once every five years per arch. A D5211 claim for the same arch within the frequency window will be denied. If early replacement is clinically necessary, submit a narrative with the claim documenting the reason, such as significant additional tooth loss, prosthesis fracture, or substantial change in the patient's oral condition.
Partial dentures, including resin-base partials, typically require pre-authorization. Treating without pre-auth approval and then billing is one of the most avoidable denial scenarios. Verify the requirement at eligibility check, submit pre-auth with radiographs and a list of missing teeth, and do not proceed with fabrication until written approval is received.
D5211 must not be billed when the prosthesis has a cast metal framework. If the lab fabricated a cobalt-chromium framework partial and D5211 was billed, that is a coding error. The correct code for a maxillary partial with a cast metal framework is D5213. The material and design must match the code billed.
Shows all remaining maxillary teeth, bone levels, and the extent of tooth loss. The primary image used for pre-authorization and clinical necessity review.
Identify each missing upper tooth by universal number. The payer uses this to apply the missing tooth clause and to confirm that a partial denture is appropriate given the number and location of missing teeth.
Document that D5211 (resin-base partial, no cast metal framework) is the chosen design and explain the clinical rationale. Note the abutment teeth and confirm that all clasping and retentive elements are incorporated in the resin base.
Include probing depths or a summary that abutment teeth are periodontally adequate to support the partial. Payers may request this information to verify clinical suitability.
Record the pre-auth number and approval in the patient record. Include the pre-auth reference number in the claim. Keep the approval letter on file in case of audit or appeal.

Get a free AR analysisD5211 is the CDT code for a maxillary (upper arch) removable partial denture with a resin base, including retentive/clasping materials, rests, and teeth. There is no cast metal framework. It is used when natural upper teeth remain and can serve as abutments for the partial.
D5211 is an all-resin partial with no cast metal framework. D5213 includes a precision cast metal framework (typically cobalt-chromium) with resin bases. D5213 is generally more durable. D5211 may be appropriate when cast metal is not clinically required or when a metal-free design is preferred.
D5211 is for the maxillary (upper) arch. D5212 is for the mandibular (lower) arch. Both are resin-base partial dentures with no cast metal framework. Arch location is the only distinction between the two codes.
The most common reasons are the missing tooth clause (upper teeth were missing before coverage began), frequency limitations (partial replacement within five years), missing pre-authorization, and code mismatch (billing D5211 when the prosthesis actually has a cast metal framework).
Most plans require pre-auth for all removable partial dentures, including resin-base designs. Confirm the requirement at eligibility check, submit pre-auth with radiographs and a missing tooth list, and wait for written approval before proceeding.
D5211 is appropriate when a cast metal framework is not clinically necessary, when the patient has a metal allergy, when a transitional prosthetic that can be easily modified is preferred, or when the dentist and patient agree that an all-resin design fits the clinical situation and patient goals.
