D5227 is the CDT code for an immediate upper partial denture on a flexible nylon base, seated the same day the failing upper teeth are extracted.
- When to use: The patient keeps some upper teeth, and a definitive flexible partial made before surgery goes in on the same date as the extractions.
- When not to use: A flexible upper on a healed ridge is D5225, a resin immediate is D5221, a cast metal immediate is D5223, and a planned temporary flipper is D5820.
- Billing note: Many plans pay D5227 at the D5221 resin allowable or exclude flexible bases entirely, so verify which applies and put the likely remake in the signed estimate.
What D5227 covers
D5227 reports an immediate partial denture for the maxillary arch on a flexible base. The base is a tissue-toned, metal-free nylon thermoplastic with gum-colored clasps formed from the base material. It is made from pre-extraction impressions and seated at the visit where the remaining failing upper teeth are removed.
The one fee includes the clasping, rests, replacement teeth, records, fabrication, delivery, and the limited follow-up care within the code’s scope. The code arrived in CDT 2022, alongside D5228, to give immediate flexible cases their own code; before that they were billed on codes that didn’t fit well.
It does not cover:
- The conventional (healed-ridge) upper flexible partial. That is D5225.
- The immediate lower flexible partial. That is D5228.
- Immediate upper partials on resin (D5221) or a cast metal framework (D5223).
- The same-day extractions, billed per tooth on D7140 or D7210.
- An interim or transitional flipper. That is D5820 on the upper arch.
When to bill D5227
Bill D5227 when the patient keeps some upper teeth, the flexible-base partial was made before the surgical visit, and it seats the day of the extractions. If the treatment plan calls the appliance temporary, it belongs on D5820 instead.
The reline problem, priced out
Every immediate prosthesis has a second stage: the ridge under it resorbs, and the fit at delivery will not be the fit at six months. On resin and cast metal immediates, the fix is a reline. On a flexible base it often isn’t, because nylon thermoplastic resists relining and repair. The conventional D5225 page covers that limitation; it matters more here because the immediate workflow guarantees the ridge will change.
A D5227 case has three realistic second-stage paths, all worth pricing at treatment planning:
- Attempt a reline anyway. Some labs will process a reline on some flexible systems. It is case-by-case and not something to promise a patient in advance.
- Remake the flexible partial on the healed ridge. That is a second lab fee and a second claim that most plans will read against the partial frequency limit the D5227 claim just started. Coverage for a remake inside the window is plan-dependent and often zero.
- Convert to a different material, a resin or cast metal partial on the healed ridge that relines normally. It runs into the same frequency limit.
Some treatment plans avoid the problem by using an interim D5820 through healing and delivering the definitive flexible partial as a D5225 on the stable ridge. That sequencing is the dentist’s decision, but the front desk should be able to explain its billing consequences.
Coverage: the flexible-base problem carries over
Carriers treat the immediate version the same way they treat conventional flexible partials. The recurring patterns, all plan-dependent:
- Alternate-benefit downgrade. The plan pays D5227 at the resin immediate (D5221) allowable and the patient owes the difference.
- Non-covered benefit. The plan excludes flexible bases entirely, and the patient owes the full fee. The gap between this and a downgrade is wide enough that verification must establish which applies before the case starts.
- Newer-code handling. D5227 and D5228 date to 2022, and plan documents written for the older code set sometimes process them by report or fold them into the nearest listed benefit. If the plan’s certificate doesn’t list the code, ask how it processes.
Verification on this code needs four answers: whether flexible base is covered, downgraded, or excluded; the partial frequency window; the missing-tooth clause; and how the plan handles a remake after an immediate. The case price is the sum of those answers.
Estimate the whole course of treatment (D5227 now plus the healed-ridge refit or remake later) and have the patient consent to both. Don’t promise a reline: chart “evaluate at healing; likely remake” and quote accordingly.
Top reasons D5227 loses money
- Flexible base excluded or downgraded. The most common issue, inherited from the material class. Verify before the impression.
- The healed-ridge remake wasn’t priced. The second prosthesis denies on frequency, and the patient hears the number for the first time mid-treatment.
- Missing-tooth clause on teeth lost before the effective date, applied per tooth or against the whole prosthesis depending on the plan.
- Unrecognized code. A plan document without the 2022 codes pends the claim or remaps it. A narrative and the material documentation shorten the round trip.
- Intent mismatch. A temporary appliance billed as definitive, or the reverse. Reviewers check the chart’s stated plan. Flexible plus same-day is D5227, flexible plus healed is D5225, and resin plus same-day is D5221; the extraction dates on the claim will confirm or contradict the code.
Documentation that supports the claim
- Delivery-date claim with the maxillary arch, and per-tooth extraction codes on the same date.
- Pre-extraction radiograph and the treatment plan naming extraction and abutment teeth.
- Material documentation: flexible nylon base, metal-free, with the brand in the chart if useful.
- The signed pre-treatment estimate covering the downgrade or exclusion scenario and the second-stage remake cost.
- A chart note on the reline limitation conversation. It protects the office when the patient expects a chairside refit the material can’t take.
FAQs
- What's the difference between D5227 and D5225?
- Delivery timing. Both are maxillary flexible-base partials with the clasps, rests, and teeth in the one code. D5225 is delivered on a ridge that has already healed. D5227 is made before the extractions and seated the same day the teeth come out. D5227 and D5228 were added to the code set in 2022; before that there was no immediate-specific flexible-base code.
- Is D5227 the code for an immediate Valplast partial?
- Yes. Valplast is a brand of flexible nylon thermoplastic, and brand-name flexible partials bill on the flexible-base codes: D5227 for an immediate upper, D5228 for an immediate lower, and D5225/D5226 for the conventional versions. Carriers pay on the CDT code and the material class, not the brand, so the claim says flexible base; the chart can name the product.
- Can an immediate flexible partial be relined as the ridge heals?
- Often not. Flexible nylon bases are difficult to reline (many labs won't attempt it, and chairside reline materials don't bond to the nylon), and they generally can't be repaired or have teeth added. Because an immediate prosthesis sits on a ridge that will shrink, the post-healing refit on a D5227 case frequently means a new prosthesis. Whether the second prosthesis is covered depends on the plan's frequency rules, so price the case assuming the remake will happen.
- Why did the carrier downgrade or deny the D5227 claim?
- Because many plans pay flexible-base partials at the resin-base allowable as an alternate benefit, treating the metal-free base as an elective upgrade, and some exclude flexible bases outright. Both carry over to the immediate version: the patient owes either the flexible-to-resin gap or the full fee. Which applies is plan-specific, so verify before treatment planning, not after delivery.
- What's the difference between D5227 and D5820?
- Intent. D5820 is an interim partial, a transitional flipper worn while definitive treatment finishes, and it is where many flexible temporaries belong when the treatment plan calls the appliance temporary. D5227 is a definitive immediate prosthesis. Billing a planned-temporary flexible appliance as D5227 starts the partial frequency clock and misstates the plan; billing a definitive flexible partial as interim undersells it. The chart's stated intent decides.
