D5221 is the CDT code for an immediate partial denture on the upper arch with a resin (acrylic) base, fabricated in advance and seated at the same visit the hopeless maxillary teeth are extracted, with the clasps, rests, and teeth included in the one fee.
The word that changes the billing is immediate. The code's own scope note limits the included follow-up care and excludes future relines and rebases, so a D5221 case is a two-claim plan from day one: the partial now, the refit (D5740 chairside or D5760 lab) months later, after the extraction sites remodel and after whatever reline waiting period the plan imposes.
What D5221 covers
D5221 reports an immediate partial denture for the maxillary (upper) arch on a resin base. The workflow defines the code: impressions are taken while the failing teeth are still in place, the lab builds the partial to the projected post-extraction anatomy, and the prosthesis is seated at the same appointment where those teeth are removed. The retentive clasping, the rests, and the replacement teeth are all inside the one fee, along with the pre-extraction records, fabrication, delivery, and the limited follow-up the scope note allows.
It does not cover:
- A conventional maxillary resin partial delivered on a healed ridge. That is D5211.
- The mandibular immediate resin partial. That is D5222.
- An immediate maxillary partial on a cast metal framework. That is D5223.
- An immediate maxillary partial on a flexible base. That is D5227.
- The extractions performed at the delivery visit. Those bill per tooth on the surgical codes (D7140, D7210).
- Future relines or rebases, explicitly excluded by the code’s scope. Chairside reline of a maxillary partial is D5740, laboratory reline is D5760, rebase is D5720.
- An interim partial worn while definitive treatment is pending. That is D5820 on the upper arch.
- An immediate complete denture for a fully cleared upper arch. That is D5130.
The two-claim structure of an immediate partial case
An immediate partial sits on a ridge that is actively healing. Over the following months the extraction sites fill in and the ridge contour shrinks, and the base that fit at delivery stops fitting. This isn’t a failure of the prosthesis; it’s the expected course, and the CDT scope anticipates it by excluding future relines from D5221.
That makes the billing a two-stage plan:
- Delivery date: D5221 on the surgical visit, with the extractions on their own per-tooth codes.
- Months later: the refit, D5740 (chairside) or D5760 (laboratory) reline of the maxillary partial, or D5720 if the whole base is replaced.
The stage-two claim has its own obstacles. Many plans impose a waiting period before they cover a reline on a newly delivered prosthesis, on the theory that early refitting is part of the delivery workflow; how long that window runs is plan-dependent. Submit the reline inside it and the denial reads as “included in the denture benefit”: a timing problem, not a coding one.
When to bill D5221
Bill D5221 when:
- The patient keeps some maxillary teeth (a partial, not a complete denture case).
- The partial was fabricated before the extraction appointment.
- The base is resin (acrylic), and the prosthesis seats the same day the teeth come out.
Do not bill D5221 for:
- A partial delivered after the ridge has healed. Use D5211.
- A cast metal framework case. Use D5223 for the immediate version.
- A flexible nylon base. Use D5227.
- A transitional flipper the patient will wear only until an implant or bridge is done. Use D5820.
The material and timing grid
The immediate partial codes mirror the conventional partial codes one-for-one. Same arch, same material; the only new axis is delivery timing:
| Base material | Conventional (healed ridge) | Immediate (day of extraction) |
|---|---|---|
| Resin, upper | D5211 | D5221 |
| Resin, lower | D5212 | D5222 |
| Cast metal, upper | D5213 | D5223 |
| Cast metal, lower | D5214 | D5224 |
| Flexible, upper | D5225 | D5227 |
| Flexible, lower | D5226 | D5228 |
Coding a same-day case as D5211 misstates the procedure, and it’s discoverable: the extraction codes on the same claim carry the same date of service. Carriers that review immediate cases read exactly that.
Top reasons D5221 claims lose money
- Reline submitted inside the plan’s waiting window. The stage-two refit denies as included in the prosthesis benefit. Verify the window length up front and schedule the reline claim past it when clinically reasonable.
- Frequency limit from a prior partial. Most plans pay one partial per arch per five-to-ten-year window, and a prior covered partial, even a conventional one, usually starts the clock. Plan-dependent; pull the history during verification.
- Missing-tooth clause on the previously missing teeth. Teeth extracted at delivery are current, but teeth lost before the effective date can be carved out or can sink the whole prosthesis, depending on the plan’s clause.
- Coded as conventional. D5211 on a same-day case invites a correction request when the extraction dates match the delivery date.
- No pre-extraction documentation. Some carriers want the radiograph and treatment plan showing which teeth are being removed and which remain. Attach up front.
Documentation that supports the claim
- Date of service = the delivery/extraction date, with the extractions listed per tooth on their surgical codes.
- Arch designation for the maxillary arch.
- Pre-extraction radiograph and the treatment plan identifying the teeth to be removed and the abutment teeth that remain.
- In the chart: the pre-extraction impression date, the teeth replaced (with the date each was lost, for missing-tooth-clause purposes), the ridge condition at delivery, and the planned reline timeline. That last note is what supports the stage-two claim when it comes.
What to get right in your PMS
- Code the timing, not just the material. Same-day delivery on a resin upper partial is D5221; healed-ridge delivery is D5211.
- Queue the reline as a future claim at case acceptance. D5740 or D5760 with its own date of service, scheduled past the plan’s waiting window.
- Bill the surgery separately. The extractions are per-tooth surgical codes, never bundled into the partial fee.
- Ask verification three questions: partial frequency history, missing-tooth clause, reline waiting period. Those three answers price the whole case.
FAQs
- What's the difference between D5221 and D5211?
- Timing relative to the extractions. Both are maxillary partials on a resin base with the clasps, rests, and teeth in the one code. D5211 is the conventional partial, made on a healed ridge weeks or months after the teeth came out. D5221 is fabricated before the extractions and seated the same day the teeth are removed, over the fresh sockets. If the partial goes in on the surgical date, the code is D5221.
- Does D5221 include the reline the patient will need later?
- No, and this exclusion is written into the code's scope: D5221 includes limited follow-up care only and does not include future relining or rebasing. As the extraction sites heal and the ridge remodels, the fit loosens and the refit bills on its own codes: D5740 for a chairside reline of a maxillary partial, D5760 for a laboratory reline, D5720 for a full rebase. Many plans also hold a waiting period after a new prosthesis before covering a reline; the length is plan-dependent, so verify it before promising a timeline.
- Are the extractions billed separately from D5221?
- Yes. D5221 covers the prosthesis only. The teeth removed at the delivery visit bill per tooth on their own surgical codes: D7140 for erupted-tooth extractions, D7210 when the removal is surgical. The prosthetic benefit and the surgical benefit are separate determinations on most plans, and a denial on one doesn't automatically follow the other.
- Does the missing-tooth clause apply to an immediate partial?
- It can, but differently than on a conventional case. The clause excludes replacement of teeth already missing before the patient's coverage started. On a D5221 case the teeth being replaced at delivery are extracted that day, under current coverage, but if the partial also replaces teeth lost years earlier, a plan can prorate or deny for those. How a carrier splits it is plan-dependent; ask about the clause tooth by tooth during verification.
- What's the difference between D5221 and D5820?
- Intent. D5221 is a definitive prosthesis delivered immediately after extractions; it is the treatment plan's end state for that arch, at least until a remake. D5820 is an interim partial (the flipper): a transitional appliance worn while something else (an implant, a bridge, a definitive partial) is pending. Carriers price them differently and often exclude interim appliances when a definitive prosthesis follows soon after, so coding the intent wrong sets up the wrong benefit.
