D5730 is the CDT code for relining a complete upper denture chairside, with the new material shaped in the mouth in one visit.
- When to use: An existing complete upper denture has lost fit, and the reline is finished at the chair the same visit.
- When not to use: A lab reline is D5750, a complete lower is D5731, an upper partial is D5740, and a temporary liner to heal irritated tissue is D5850.
- Billing note: Plans commonly exclude relines for 6 to 12 months after a new denture, so check the delivery date and last reline date before starting.
What D5730 covers
D5730 reports a direct reline of a complete maxillary denture. Reline material is placed inside the existing denture, shaped against the patient’s upper ridge and palate in the mouth, and finished at the chair. The procedure takes one visit, and the patient never gives up the denture. The lab reline (D5750) keeps the denture out of the mouth for a day or two but replaces the entire tissue surface with processed acrylic.
Bill D5730 when an existing complete upper denture has lost adaptation or suction and the refit is done in the mouth and finished the same visit. The material must be intended as the working fit surface, not a short-term therapeutic liner.
It does not cover:
- The same reline processed at a lab. That’s D5750.
- A chairside reline of a complete lower denture. That’s D5731.
- A chairside reline of an upper partial denture. That’s D5740 (the lower partial is D5741).
- Tissue conditioning, a short-term therapeutic liner placed to heal irritated tissue before a reline or new denture. That’s D5850 for the upper arch.
- A rebase, which replaces the entire denture base rather than resurfacing it. That’s D5710 for the complete upper.
- A sore-spot adjustment with no new material added. That’s D5410.
Chairside versus laboratory: the axis that prices the claim
| Chairside (direct) | Laboratory (indirect) | |
|---|---|---|
| Complete upper | D5730 | D5750 |
| Complete lower | D5731 | D5751 |
The chairside reline is done in the mouth with self-curing or light-cured material in a single visit. It is faster and cheaper. Most fee schedules set its allowable below the lab reline, because the lab process produces a denser, longer-lasting surface. Two coding failures follow from that price gap:
- Lab code, chairside work. D5750 is submitted for a reline finished at the chair. If the carrier requests records, the chart note shows the technique, the claim reprocesses at the D5730 allowable, and the office has a records-review flag on file.
- Tissue conditioning billed as a reline. A temporary soft liner placed to calm inflamed tissue is D5850, not a reline. Billing D5730 for it can use up the patient’s reline frequency benefit, which matters when the real reline comes months later.
If the plan changed mid-visit (the office intended a chairside reline, the tissue wouldn’t cooperate, and the case went to the lab), code what actually happened on the date it was delivered.
Top reasons D5730 gets denied
- Post-delivery waiting period. Plans commonly exclude relines for 6 to 12 months after a new denture. Inside the window, the claim needs a narrative documenting early fit failure, or it denies. The exact window is plan-dependent.
- Frequency limit. After the initial exclusion, plans typically cap relines per arch, commonly once every 12 to 36 months. A chairside reline and a lab reline usually draw from the same frequency bucket, so a D5730 this year can block a D5750 next year.
- Technique mismatch on records review. The note describes lab processing but the claim says chairside, or the reverse. The claim reprocesses at the other allowable.
- Reline billed on the same date as denture delivery. A reline on day one of a new denture reads as a fabrication problem or a coding error, and carriers deny it as included in the denture fee.
- Tissue conditioning coded as a reline. Some carriers cover D5850 differently from relines, or not at all. Either way, the mislabel distorts the frequency history.
Documentation that supports the claim
- Upper-arch designation, with the date of service as the visit the reline was completed.
- The delivery date of the denture being relined, which drives the waiting-period math.
- The clinical reason: loss of retention, ridge resorption, adhesive dependence, or sore spots traced to poor adaptation.
- A note that the reline was performed directly at the chair. This line protects the claim if records are requested.
- Any prior reline or tissue-conditioning dates on the same arch.
Example case
A patient’s three-year-old complete upper denture has gradually lost suction, and she uses adhesive daily. Tissue is healthy, and the base and teeth are sound. She works a front-desk job and can’t be without the denture for a lab cycle, so the dentist performs a chairside hard reline in one visit.
Billing steps:
- Verify reline coverage, the frequency rule, and any post-delivery waiting period. A three-year-old denture clears the waiting period on essentially every plan.
- Confirm no reline on this arch inside the frequency window.
- Complete the direct reline and submit D5730 with the maxillary arch designation on that date of service.
- Note in the chart that the reline was performed chairside and why a lab reline wasn’t chosen, in case the carrier questions the technique later.
- Collect coinsurance against the chairside allowable, which is lower than the lab reline fee the patient may have been quoted on an old treatment plan.
FAQs
- What is the dental code for a chairside denture reline?
- D5730 for a complete upper denture and D5731 for a complete lower denture. Both report a direct reline, with the material placed and shaped against the tissue in the mouth and the denture returned the same visit. The laboratory versions are D5750 (upper) and D5751 (lower).
- What's the difference between D5730 and D5750?
- The technique. D5730 is done directly at the chair in one visit. D5750 sends the denture to a lab, which strips and reprocesses the entire tissue surface, usually leaving the patient without the denture for a day or two. The lab reline is more durable, and most plans set a higher allowable on it. Bill the technique the chart note supports.
- Is a soft reline billed as D5730?
- Yes, if the soft liner is placed chairside as the definitive reline of a complete upper denture. D5730 applies whether the material is hard or soft. A short-term therapeutic soft liner placed to let irritated tissue heal is tissue conditioning, D5850 for the upper arch, not a reline. The distinction is intent: definitive refit versus temporary tissue treatment. Coverage for either is plan-dependent.
- Why did the plan deny a D5730 reline on a fairly new denture?
- Most plans exclude relines for a set period after a new complete denture, commonly 6 to 12 months, on the theory that a recent denture should still fit. Inside that window the claim pends or denies unless a narrative documents why the fit failed early, such as rapid ridge resorption after extractions. The window varies by plan, so pull it at verification along with the reline frequency rule.
- Can I bill D5730 for a partial denture or a lower denture?
- No. D5730 is complete upper only. The chairside reline of a complete lower is D5731, an upper partial is D5740, and a lower partial is D5741. Carriers cross-check the patient's prosthetic history, so an arch or prosthesis mismatch is a preventable rejection.
