D5110 Dental Code: Maxillary Complete Denture Billing Guide

What D5110 covers

D5110 reports a conventional complete denture on the maxillary (upper) arch: full-coverage removable prosthesis with a complete set of artificial teeth seated on an acrylic resin base shaped to the patient’s healed alveolar ridge and palate. The code includes the diagnostic impressions, the bite registration, the wax try-in, the laboratory fabrication, the delivery appointment, and the initial post-delivery adjustments included within the standard delivery workflow.

It does not cover:

• Conventional complete denture on the mandibular arch. Use D5120.
• Immediate complete denture on the maxillary arch (delivered same day as extractions). Use D5130.
• Immediate complete denture on the mandibular arch. Use D5140.
• Partial dentures, including cases where the patient still has some natural teeth. Use the D5211–D5226 series for resin-based partials or the D5213–D5214 series for cast metal frameworks.
• Implant-supported overdentures. Use the D6110–D6113 series.
• Post-delivery adjustments after the standard included period. Use D5410 (maxillary adjustment).
• Relines, rebases, or repairs. Use the D5710–D5751 series for relines and rebases, and D5512 or D5520 for repairs.

The code is specifically for a conventional workflow where the patient’s extractions have healed and the prosthesis is fabricated on a stabilized ridge.

When to bill D5110

Bill D5110 when:

• The patient has a fully edentulous maxillary arch (no remaining upper teeth).
• Extraction sites, if relevant, have healed sufficiently for definitive impressions (typically 6 to 8 weeks minimum after the last extraction).
• A conventional complete denture has been fabricated and delivered.

Do not bill D5110 for:

• Immediate dentures delivered the same day as extractions. Use D5130.
• Partial dentures. Use the appropriate D5211–D5226 code.
• Denture relines, rebases, or repairs done on an existing denture.

Conventional versus immediate denture

The most consequential billing decision on a complete-denture case is whether the prosthesis is conventional (D5110) or immediate (D5130). The clinical workflow and the billing are both different.

Conventional (D5110):

• Extractions completed first, healing period of weeks to months.
• Final impressions taken on healed, stable ridge.
• Denture fabricated to fit the post-healing anatomy.
• Delivered at a later appointment.
• Generally fits better long-term because the ridge has stabilized.

Immediate (D5130):

• Extractions and denture delivery on the same day.
• Impressions taken before extractions (typically a few weeks earlier).
• Denture fabricated on a model that includes the teeth to be extracted.
• Patient leaves the surgical visit with the denture in place.
• Requires relines or remake as the ridge resorbs over the following months.

The two procedures serve different patient needs (immediate for patients who can’t be without teeth, conventional for patients who can wait), and the billing reflects which procedure was actually delivered. Choose the code that matches the workflow.

Top reasons D5110 gets denied or downgraded

Five issues account for most problems on this code:

1. Frequency limit hit. The patient’s prior denture is within the plan’s five- or seven-year frequency window. The denial is typically clear; an appeal with documentation of clinical necessity (lost denture, structural failure, ridge resorption requiring new fabrication) succeeds on some plans but not others.
2. Pre-existing edentulism exclusion. The patient was already edentulous before the policy started. Some newer commercial plans exclude prosthetic coverage on pre-existing edentulous arches. Verify before treatment planning.
3. Wrong code for immediate denture. D5110 billed when the denture was delivered the same day as extractions. Recode as D5130 and resubmit. The carrier may identify the issue from the extraction history and request the correction.
4. Documentation of edentulism missing. Some plans require documentation that the arch is fully edentulous before paying for a complete denture. A panoramic radiograph or chart entry confirming the absence of remaining teeth typically satisfies the request.
5. Coverage at alternate-benefit level. Some plans pay D5110 at a basic flipper or interim partial allowable for patients who could clinically use a less expensive option. Less common than the frequency or pre-existing issues but it happens on certain individual plans.

The post-delivery sequence: adjustments, relines, repairs

D5110 ends at delivery. Everything that happens after is a separate code.

Adjustments:

• D5410 (adjust complete denture, maxillary) for the upper.
• D5411 (adjust complete denture, mandibular) for the lower.

Most plans include a handful of adjustments in the denture delivery period (typically 30 days, sometimes 90), after which D5410 is billed per adjustment visit.

Relines:

• D5710 (rebase complete maxillary).
• D5711 (rebase complete mandibular).
• D5730 (reline complete maxillary, chairside).
• D5731 (reline complete mandibular, chairside).
• D5750 (reline complete maxillary, laboratory).
• D5751 (reline complete mandibular, laboratory).

Relines and rebases are typically not covered by insurance for a period after the original denture (often 6 to 24 months), and have their own frequency limits afterward.

Repairs:

• D5512 (repair broken complete denture base, maxillary).
• D5520 (replace missing or broken teeth).

Repair codes have separate frequency rules and most plans cover them.

Documentation that supports the claim

The claim needs:

• Date of service (the delivery date, not the impression or wax try-in dates).
• Tooth code field for arch designation (most PMSes use the upper arch indicator UA or area-of-oral-cavity code 01).
• Panoramic radiograph or supporting documentation if the plan requires evidence of edentulism.

For the patient record, document:

• Impression dates and bite registration dates.
• Wax try-in date and patient acceptance.
• Delivery date.
• Material and shade selected.
• Initial post-delivery instructions and adjustment schedule.
• Date of last extractions (relevant if recent, to support the conventional rather than immediate workflow).

If the patient is a denture-replacement case, the chart should also document the date of the prior denture (for frequency calculations) and the clinical reason for replacement.

Example case

A 68-year-old patient has been wearing a maxillary complete denture for 11 years. The denture has lost retention as the ridge has resorbed and the patient reports daily discomfort. The dentist confirms the ridge changes, takes diagnostic impressions, and treatment-plans a new conventional maxillary complete denture.

Treatment sequence:

1. Visit 1: diagnostic impressions, shade selection.
2. Visit 2: final impressions on custom trays.
3. Visit 3: bite registration.
4. Visit 4: wax try-in and patient verification.
5. Visit 5: delivery of the new denture.

Billing steps:

1. Verify the patient’s plan and confirm denture coverage. Pull the frequency rule (most likely 5 or 7 years) and confirm the prior denture is outside the window (11 years old).
2. Submit D5110 on the delivery date with arch designation 01 (upper).
3. If the plan requires evidence of edentulism, attach a panoramic radiograph.
4. Schedule the patient for post-delivery adjustments. Bill D5410 per visit after the standard delivery-included period.

If the prior denture is within the frequency window, an appeal would need to document the clinical necessity for replacement: ridge resorption beyond what relining can address, structural failure of the existing base, or anatomic change that makes the existing denture unusable.

What to verify before the delivery appointment

The specifics vary across Open Dental, Dentrix, Eaglesoft, Curve, and Carestream. The steps that matter:

1. Use D5110 for the conventional workflow only. Immediate dentures use D5130. The code on the claim should match the actual delivery workflow.
2. Bill on the delivery date. The diagnostic and impression visits are part of the D5110 workflow and don’t get separate code entries.
3. Confirm the frequency rule on every denture case. Pull the date of the prior denture before treatment planning. A surprise frequency denial after delivery is hard to walk back.
4. Set the arch designation correctly. Maxillary is D5110. Mandibular is D5120. A claim with the wrong arch designation is a common preventable rejection.
5. Treat post-delivery work as separate billing. Adjustments, relines, repairs all have their own codes with their own coverage rules.

If your office sees recurring problems on complete-denture billing, the cause is usually a missed frequency check or a workflow that doesn’t separate the delivery procedure from the post-delivery adjustment and reline procedures. A treatment-planning checkpoint that confirms the frequency rule before the first impression prevents most denials.
