D5223 Dental Code: Immediate Maxillary Cast Metal Partial

What D5223 covers

D5223 reports an immediate maxillary partial denture built on a cast metal framework with resin denture bases. The lab casts the framework and processes the saddles against a model predicting the arch after surgery; at the delivery visit the remaining condemned upper teeth are extracted and the partial seats over the fresh sites. One fee covers the framework, the resin bases, the retentive clasping and rests, the replacement teeth, and the limited follow-up care in the code’s scope. Future relines and rebases are explicitly outside it.

It does not cover:

• The conventional (healed-ridge) maxillary cast metal partial. That is D5213.
• The mandibular immediate cast metal partial. That is D5224.
• The all-resin immediate upper partial. That is D5221.
• The flexible-base immediate upper partial. That is D5227.
• The same-day extractions, billed per tooth on D7140 or D7210.
• Reline of the resin saddles after healing (D5740 chairside, D5760 laboratory) or repair of the framework (D5622, maxillary).
• An immediate complete upper denture when no teeth remain. That is D5130.

The downgrade math on a premium immediate

Cast metal is the top of the partial price ladder, and plans that apply an alternate-benefit clause to partials generally apply it here too: the claim processes, the clause substitutes the least-costly professionally adequate alternative, and payment issues at the resin-immediate (D5221) allowable. That is not a denial; the patient owes the gap between the cast metal fee and the resin allowable, plus coinsurance calculated on the smaller number.

Whether the clause applies, and what it downgrades to, is plan-specific. Some plans pay cast metal partials in full at the contracted fee; some exclude the upgrade; some don’t distinguish. The only reliable answer is the one verification pulls for the actual policy, and on a case this expensive it belongs in a written pre-treatment estimate before the framework is cast.

Why this code draws clinical review

An immediate partial exists to spare the patient an edentulous interval; a cast metal partial exists to fit precisely. Those goals pull against each other, because the precise fit is taken against an arch that surgery is about to change. Offices resolve the tension in different legitimate ways (casting the framework to the planned post-extraction contour, planning an early saddle reline, or staging with a resin or interim appliance first), but the claim file should show the reasoning: the treatment plan, which teeth are being removed, which abutments the framework rests on, and why the definitive framework is going in now rather than after healing. Carriers that review high-fee removable prosthetics ask exactly that question, and a chart that answers it preempts the request for records.

When to bill D5223

Bill D5223 when the patient retains some maxillary teeth, the framework-based partial was fabricated before the surgical appointment, and delivery happens the day the teeth are extracted. Healed-ridge delivery of the same prosthesis is D5213. An all-resin same-day case is D5221; flexible nylon is D5227; the lower-arch framework version is D5224.

Top reasons D5223 gets denied or downgraded

1. Alternate-benefit downgrade to resin. Paid at the D5221 (or even conventional resin) allowable, patient owes the difference. Plan-dependent; catch it at verification, not on the EOB.
2. Frequency limit. One partial per arch inside the plan’s replacement window, and a prior covered partial of any material usually starts the clock.
3. Missing-tooth clause. Teeth extracted at delivery are current, but previously missing teeth the partial also replaces can be carved out or ground for denial, depending on the plan’s clause.
4. Records request on the immediate framework. No pre-extraction radiograph or treatment plan attached, so the claim pends while the carrier asks why a definitive cast prosthesis seated on surgery day.
5. Reline billed too soon. The post-healing saddle reline lands inside the plan’s post-delivery waiting window and denies as included. Schedule the stage-two claim against the verified window.

Documentation that supports the claim

• Delivery-date claim, maxillary arch designation, extractions listed per tooth with the same date of service.
• Pre-extraction panoramic or periapical radiographs and the written treatment plan naming extraction teeth and abutment teeth.
• Chart: framework try-in notes (if a try-in preceded surgery), ridge condition at delivery, the reline plan for the saddles, and the rationale for a definitive framework at the immediate stage.
• Fee submitted from the office fee schedule, with the pre-treatment estimate on file showing the patient saw the downgrade math before consenting.

What to get right in your PMS

1. Price the downgrade before the lab bill. If the plan pays cast metal at the resin allowable, the patient’s share is large. Get it into the signed estimate.
2. Code timing and material together. Same-day plus framework is D5223; healed-ridge framework is D5213; same-day all-resin is D5221.
3. Split the surgery. Extractions bill per tooth on their own codes, always.
4. Route follow-up to partial-specific codes. Saddle relines are D5740/D5760, framework repair is D5622, adjustments are D5421. These are maxillary partial codes, not complete-denture ones.
