ADA Code 5110: Coverage, Billing, and Verification

Front desks see ADA code 5110 on treatment plans every time a patient needs a full upper denture. The code itself is simple. What trips up billing is everything around it: does the plan still cover a denture this cycle, does the patient have a missing tooth clause, and was a denture billed too recently for this arch. Get any of those wrong and the claim comes back weeks later, usually after the patient has already left the chair.

ADA code 5110 is the CDT code for a complete denture, maxillary. Dentists use it when a patient needs a full removable prosthesis for the entire upper arch, after all upper teeth are gone or are scheduled for extraction. The code covers the finished denture along with the visits that lead up to it, primary and final impressions, jaw relation records, and delivery of the denture. It does not include the extractions themselves, an immediate denture placed the same day as extractions (that is a different code), or a reline done later. Most dental plans pay for one complete maxillary denture every five to eight years, and many require proof that the upper arch was already missing all its teeth, or a missing tooth clause showing when the loss happened. A front desk that checks these plan rules before the appointment, rather than after the claim is filed, cuts down on denials and on calls asking the patient to come back with more paperwork.

Code 5110 pays for the finished denture and the appointments used to get there: primary and final impressions, jaw relation records, and delivery of the finished prosthesis. It does not include the extractions, a temporary immediate denture (a different code covers that), tissue conditioning done afterward, or a reline needed months or years later. Our D5751 dental code guide covers reline coverage and billing steps if that comes up on the same arch. A denture adjustment done in the first few weeks after delivery is usually included in the global fee. Adjustments after that window often get billed separately, and plans differ on how long that window runs, so it is worth checking before you tell a patient an adjustment is free.

The most common reason we see is a missing tooth clause: some plans will not pay for a denture unless the patient was already missing the front teeth of the arch before they enrolled, or unless it can be shown the loss happened while the plan was active. The second most common reason is frequency. Most plans pay for one complete maxillary denture per arch every five to eight years, and if the patient's history shows a denture billed more recently, the claim denies outright. A third reason is documentation. Some payers want a narrative, pre-op photos, or extraction dates before they will pay, and if that is not attached the first time, the claim sits in a queue until someone calls to ask for it. Our D5110 dental code guide walks through the denial letters we see most and how to fix each one, and the D5110 code description page lists what most payers ask for before they pay.

The check that actually prevents these denials is an eligibility and benefits check run before the denture appointment, not after the claim is filed. Sign in and check any patient in one click, and in under a second you get the plan's missing tooth clause, the last date a denture or reline was paid, and whether prosthodontics needs a pre-authorization. Insurance verification on its own starts from $49 a month per location, priced by how many checks the office runs each month, from 50 checks up to 10,000, plus $2.50 or less per check we find. It runs on demand, one click at a time, whenever a staff member is ready to check a patient. The Full System puts the same check in one monthly plan with Amy on the phones.

This is also where an AI receptionist earns its keep on denture cases. When a patient calls asking whether their plan covers a full upper denture, Amy can pull up the account, confirm the appointment is already on the schedule, and let front desk staff spend that hour on the actual checks and forms instead of the phone. Our AI receptionist for dental office page covers what Amy handles on a normal call, denture questions included.

The trend here is bigger than one code. The ADA Health Policy Institute's 2026 survey found that 43.3% of dentists already use AI for at least one task in their practice, and insurance verification is the number two planned use, with 32.6% of dentists planning to add it against 13.6% using it today. Denture cases like code 5110 are exactly where that gap shows up: high dollar claims, strict frequency rules, and a missing tooth clause that is easy to miss on a busy day.

If your practice bills ten complete dentures a month and even two of those come back denied for a missing tooth clause or frequency limit, that is two reworked claims x 20 minutes each to gather notes and resubmit, or 40 minutes of staff time a month, on top of the delay in getting paid. Plug in your own denture volume to see what two or three denials a month actually cost your front desk.

What does dental code 5110 mean?

Dental code 5110 (ADA code 5110) is the CDT code for a complete denture, maxillary. It is used when a patient needs a full removable prosthesis to replace every tooth on the upper arch, after the arch is fully edentulous or the remaining teeth are scheduled for extraction. It covers the denture itself and the visits used to fabricate it, not the extractions that came before it.

What are the common problems with maxillary partial dentures?

A maxillary partial denture is a different code and a different device than the complete denture billed under 5110. A partial keeps some natural teeth and clasps around them, while a complete denture replaces the whole arch. The issues we hear about most with any removable upper denture are looseness from bone changes over time, sore spots after a new denture, and clasps that wear loose on a partial. Fit and comfort problems are clinical decisions for the dentist to evaluate, not something the front desk should try to sort out over the phone.

What is ADA code D6110?

ADA code D6110 covers an implant or abutment supported removable denture for a fully edentulous arch, usually the upper arch. It differs from code 5110 because it is anchored to implants already placed in the bone, while a 5110 denture rests on the gum tissue alone with no implant support. Plans that cover D6110 usually require proof the arch is fully edentulous and that the implants are already in place.

When to use dental code D9110?

D9110 is billed for palliative treatment of a dental emergency, a visit to control pain or bleeding without doing the full definitive procedure that same day. It is not related to dentures. A practice might use it for a patient in pain the same week they are being planned for a 5110 denture, but the two codes are billed and processed separately.
