D5213 Dental Code: What It Covers and How to Bill It

Front desks pull up the D5213 dental code when a claim comes back downgraded, or when they need to tell a patient what a cast metal partial will actually cost before the lab work starts. Here is what the code covers, how it compares to the codes around it, and how to check coverage before you bill it.

D5213 is the CDT code for a maxillary partial denture with a cast metal framework and resin denture bases, including any conventional clasps, rests, and teeth. It applies when a patient is missing some, not all, of the upper teeth and the treatment plan calls for a metal framework instead of an all acrylic base, usually because the framework holds up better under daily wear and gives more secure clasps. D5213 is different from D5211, which is the same type of partial built on a full acrylic base with no metal framework, and different from D5214, which is the identical cast metal design placed in the lower (mandibular) arch instead of the upper. Many dental plans pay a cast metal partial at the lower D5211 rate under an alternate benefit provision, even when the treatment plan and the claim both specify D5213. Checking the patient's plan before the appointment is the only way to catch that downgrade before it becomes a billing surprise.

The full CDT description for D5213 is: maxillary partial denture, cast metal framework with resin denture bases, including any conventional clasps, rests, and teeth. In plain words, it is a removable upper partial. The visible teeth and gum colored base are resin (acrylic), but the frame underneath, the part that connects the clasps, rests, and major connector, is cast metal, usually a cobalt chromium alloy.

A cast metal framework is thinner and more rigid than an all acrylic partial, so dentists use it when the patient needs secure clasps on remaining teeth, when the span being replaced is longer, or when the patient has already broken an acrylic partial and needs something sturdier. The code covers the finished prosthesis. It does not include a separate code for adjustments, relines, or repairs; those are billed under their own CDT codes when that work is done later.

For the full list of procedure codes and how they're grouped by arch and material, the CDT procedure code guide is a useful reference when you're not sure which code a lab's description maps to.

Front desks mix up D5213 with a handful of codes that sit right next to it in the CDT book. Knowing the difference matters because billing the wrong one is one of the fastest ways to get a claim kicked back.

• D5211: maxillary partial denture, resin base. Same arch, same general purpose, but no cast metal framework. The entire base, including any clasps, is acrylic.
• D5213: maxillary partial denture, cast metal framework with resin denture bases. This is the code covered in this guide.
• D5214: the mandibular (lower arch) version of D5213. Same cast metal framework design, placed in the lower jaw instead of the upper.
• D5225: maxillary partial denture, flexible base, including any clasps, rests, and teeth. This one uses a flexible resin instead of a rigid acrylic or metal frame, and plans often reimburse it differently than D5213.

If the patient is missing every tooth in the upper arch rather than some of them, the correct code is not a partial at all. A complete upper denture is billed under D5110, and plans handle complete dentures under different frequency and waiting period rules than partials.

D5213 gets downgraded more often than it gets flatly denied. The most common reason is the alternate benefit provision written into most dental plans: the plan will pay toward a cast metal partial, but it reimburses at the rate of the cheaper resin base partial (D5211) and the patient covers the difference. That difference can be several hundred dollars, so a patient who was not told about it in advance is going to be upset when the EOB arrives.

A second reason is the missing tooth clause. Some plans will not pay anything toward a partial if the missing teeth were already gone before the patient's coverage started. We cover how that clause works, and how to read it before treatment, in our missing tooth clause guide.

A third reason is frequency. Most plans only pay for a partial once every five to seven years per arch, so a replacement partial billed too soon gets denied outright unless the record shows the original was lost, broken beyond repair, or no longer fits due to a documented change in the mouth.

The fix for all three is the same: run a dental predetermination before the lab work starts, so the practice and the patient both know the plan's answer on D5213 before anyone commits to treatment.

Checking a patient's plan before you bill D5213 means confirming four things: whether partials are covered at all, whether the plan pays cast metal at the cast metal rate or downgrades it, the frequency limit and when the patient's last partial was paid, and whether a missing tooth clause applies. All four show up on a full eligibility and benefits check, not a basic eligibility check, so the front desk needs to pull the detailed breakdown, not just confirm the patient is active on the plan.

The ADA Health Policy Institute's 2026 survey found that 43.3% of dentists already use AI for at least one task in the practice, and insurance verification is the second most common planned use, at 32.6% planned versus 13.6% currently in use. That gap between planned and current use is exactly where a code like D5213, with its alternate benefit downgrades and frequency limits, causes the most billing surprises.

With Valian's insurance verification, the front desk signs in and runs a check on any patient in one click, in seconds, instead of calling the payer or digging through a portal. Plans start from $49 a month plus $2.50 or less per check we find, sized to how many checks the office runs each month. Every payer we verify in real time is searchable on our payer list, so the office can confirm a plan is covered before scheduling the appointment.

Filing the D5213 claim itself, and following up on the payment after, is a separate step from verification. That part of the work is in development at Valian, and we are taking on our first offices for it now. Today, the office still picks the procedure code and files the claim; verification just tells you what to expect before you do.

If D5213 claims keep coming back downgraded at your practice, the fix usually starts before the appointment, not after the EOB. You can book a time to see how Valian's insurance verification works for your practice's payer mix.

What is dental procedure code D5213?

D5213 is the CDT code for a maxillary partial denture with a cast metal framework and resin denture bases, including any conventional clasps, rests, and teeth. It's billed when a patient is missing some of the upper teeth and the treatment plan uses a metal framework instead of an all acrylic base.

What is a D5214 dental code?

D5214 is the same cast metal partial denture design as D5213, but for the lower (mandibular) arch instead of the upper. The materials, clasps, rests, and billing rules are the same; only the arch changes.

What does maxillary partial denture mean?

A maxillary partial denture is a removable prosthesis that replaces some, but not all, of the teeth in the upper jaw. It's held in place by clasps or rests on the patient's remaining natural teeth, unlike a complete denture, which replaces an entire arch.

Why can't you sleep with partial dentures?

Many dentists recommend taking a partial denture out at night so the gum tissue and supporting bone get a break from steady pressure. Wearing it continuously can also trap bacteria against the tissue and the remaining natural teeth. This is general background, not care instructions for a specific patient; ask the treating dentist what they recommend for a particular case.
