D5211 is the CDT code for an upper (maxillary) removable partial denture built on a resin (acrylic) base — used when some natural upper teeth remain and others are replaced. The descriptor includes the retentive/clasping materials, rests, and artificial teeth, and there is no cast metal framework, distinguishing it from the cast-metal partial (D5213).
Informational only — confirm the official CDT descriptor and your payers' rules independently. This is general guidance, not billing, coding, or clinical advice.
When to Use the D5211 Code
Report D5211 when an upper partial denture with a resin base replaces some missing maxillary teeth while natural teeth remain to support and retain the appliance. The clasps, rests, and teeth are part of the code — they are not billed separately.
Pick the code by arch and framework: D5211 is the upper resin-base partial; D5212 is the lower resin-base partial; D5213 is an upper cast-metal-framework partial (more rigid and durable). Don't use D5211 when the arch is fully edentulous — a complete denture (D5110) applies — or when a cast metal framework is fabricated.
Documentation & Clinical Scenarios
Partials are a reviewed prosthetic benefit, so the chart should show which teeth are missing and which remain to support the appliance:
- Arch (maxillary), the teeth being replaced, and the abutment teeth carrying the clasps and rests.
- Material — a resin base (not a cast metal framework), since this drives code selection.
- Clinical notes on the impression, framework/base, and delivery date; many payers tie the benefit to the seat date.
- Prior-partial history — first placement vs. replacement, since replacements carry frequency limits.
Insurance & Billing Tips
- Verify benefits and frequency first. Partials commonly carry a replacement frequency limit (often once every 5–7 years per arch).
- Watch for an "alternate benefit." Some plans downgrade a partial to the least costly appliance, or pay a resin partial at a lower allowance than a cast-metal one; verify up front so the estimate is accurate.
- Clasps, rests, and teeth are bundled into D5211 — they aren't separate line items.
- Confirm the seat-date rule. Many plans pay on the insertion/delivery date, not the impression date.
- Pre-authorize when in doubt. A pre-estimate confirms coverage and the patient portion before fabrication.
Example Case
A 55-year-old patient is missing several upper teeth but retains enough natural teeth to support a removable partial. The dentist plans a resin-base maxillary partial. The office verifies benefits, confirms no partial on file within the plan's frequency limit, and submits a pre-estimate. The impression is taken, the resin partial with its clasps, rests, and teeth is fabricated, and the appliance is delivered. The claim is filed as D5211 with the insertion date. Because benefits were verified and the documentation showed the remaining and missing teeth, the claim is paid at the expected level.
Patients call about "a partial for my top teeth," not D5211. DentalReception AI answers and books those calls 24/7, captures insurance details for clean intake, and routes clinical and billing questions to your team. See denture calls, or book a demo.
Frequently Asked Questions
What's the difference between D5211 and D5213?
Framework. D5211 is an upper partial built on a resin (acrylic) base with no cast metal, while D5213 is an upper partial with a cast metal framework and resin denture bases. The cast-metal version is more rigid and durable, and some plans reimburse the two differently — so code by the framework actually fabricated, not by which one the patient asked about.
Does D5211 include the clasps and rests, or are those separate?
They're included. The D5211 descriptor covers the retentive/clasping materials, rests, and artificial teeth as part of the partial — they are not billed as separate line items. Repairs, additions, or adjustments performed later are reported with their own codes when clinically necessary.
How often will insurance pay for an upper partial?
Most plans apply a replacement frequency limit, commonly once every five to seven years per arch, and some apply an alternate benefit that pays a resin partial at a lower allowance. Verify the specific frequency and any downgrade rule before treatment so the patient knows whether a replacement partial is covered and what their share will be.
Do I need a pre-authorization for a D5211 partial?
Many plans recommend or require a pre-estimate for partials, since alternate-benefit downgrades and frequency limits are common. Submitting one confirms whether the resin partial is covered at the full rate or downgraded, clarifies the seat-date rule, and establishes the patient's out-of-pocket portion before fabrication begins.
