D5213 Dental Code: Maxillary Cast Metal Partial Billing Guide

What D5213 covers

D5213 reports a maxillary (upper) partial denture built on a cast metal framework supporting resin denture base areas and replacement teeth. The framework is typically chrome cobalt or another cast alloy, designed from a surveyed cast and incorporating rests, clasps, indirect retainers, and major and minor connectors. The code includes the diagnostic impressions, the surveyed cast, the framework design and try-in, the wax try-in with teeth, the laboratory fabrication, the delivery appointment, and the initial post-delivery adjustments within the standard delivery workflow.

It does not cover:

• Mandibular cast metal partial dentures. Use D5214.
• Maxillary partial dentures with resin bases and resin or wrought wire retention (no cast framework). Use D5211.
• Mandibular partial dentures with resin bases. Use D5212.
• Flexible-base partial dentures. Use D5225 (maxillary) or D5226 (mandibular).
• Complete dentures. Use D5110 (maxillary) or D5120 (mandibular).
• Implant-supported partial dentures or fixed bridges. Use the appropriate D6000 series codes.
• Post-delivery adjustments after the standard included period. Use D5421 (maxillary partial) or D5422 (mandibular partial). D5410 and D5411 are complete-denture adjustment codes and do not apply.
• Relines, rebases, or repairs. Use the D5710–D5761 series and the partial-denture repair codes (D5611/D5612 resin base, D5621/D5622 cast framework, D5650 add tooth, D5660 add clasp). For this maxillary cast metal partial specifically, repairs run through D5612 (repair resin partial base, maxillary) and D5622 (repair cast partial framework, maxillary).

The defining feature is the cast metal framework. A partial with a resin base and wire clasps is D5211, not D5213, regardless of complexity.

When to bill D5213

Bill D5213 when:

• The patient has a partially edentulous maxillary arch (some teeth remaining, some missing).
• A cast metal framework partial denture has been fabricated and delivered.
• The framework was designed from a surveyed cast and incorporates rests, clasps, and connectors as appropriate to the case.

Do not bill D5213 for:

• Resin-base partial dentures. Use D5211.
• Mandibular partials. Use D5214.
• Flipper partials or interim transitional partials. Use D5820 (maxillary interim).
• Complete dentures. Use D5110.

The missing-tooth clause and how it actually works

The missing-tooth clause is the single biggest source of patient-responsibility surprises on partial denture cases. At its core it’s a per-tooth exclusion: the plan excludes coverage for prosthetic replacement of any tooth that was missing before the patient’s current coverage started. The mechanism varies by carrier:

1. The carrier processes the D5213 claim.
2. The carrier checks the patient’s coverage history to identify which teeth were lost before coverage started.
3. Because a single partial replaces multiple teeth at once, many carriers deny the entire prosthesis if even one replaced tooth was lost before the policy started. The patient then owes the full cost out of pocket.
4. Some carriers instead prorate by tooth, paying only for the teeth lost during current coverage; the patient owes the unpaid portion plus standard coinsurance.

The whole-prosthesis denial is the larger risk, not the clean prorate. A patient who lost three teeth before the policy started and is getting a partial that also replaces one tooth lost during coverage could see the entire partial denied, not 25% covered. Some plans (notably many Delta Dental plans) apply no missing-tooth exclusion at all (“missing tooth inclusion”). The conversation at treatment planning needs to acknowledge this range. A patient who hears “your insurance covers partials” and then receives an EOB showing the whole prosthesis denied will not be happy.

Most plans document the missing-tooth clause in the benefit booklet. The cleanest way to handle it is a pre-treatment estimate with a specific dollar number for the patient’s expected out-of-pocket on the actual case.

The alternate-benefit downgrade to acrylic partial

Many plans apply an alternate-benefit clause on cast metal partials, paying D5213 at the D5211 (acrylic partial) allowable. The reasoning is that the acrylic partial is functionally adequate, and the plan only owes the lower allowable.

The math:

1. The office submits D5213 at the cast metal office fee.
2. The carrier processes and applies the alternate-benefit clause.
3. The carrier pays D5213 at the D5211 allowable.
4. The patient owes the difference between the cast metal office fee and the acrylic allowable, plus the standard coinsurance on the lower allowable.

The dollar gap is typically larger here than on most alternate-benefit scenarios because cast metal partial fees and acrylic partial fees differ by hundreds of dollars. Quote the patient the actual gap, not the generic “the plan covers partials.”

Top reasons D5213 gets denied or downgraded

Five issues account for most problems on this code:

1. Missing-tooth clause exclusion. A per-tooth exclusion for teeth lost before coverage started. Because one partial replaces several teeth, many carriers deny the entire prosthesis if any replaced tooth predates the policy; some prorate by tooth instead. The most common patient-responsibility surprise on this code.
2. Alternate-benefit downgrade to acrylic. Plan pays D5213 at the D5211 allowable. Not a denial. Bill the patient the difference and coinsurance on the lower allowable.
3. Frequency limit hit. Prior partial within the plan’s five- or seven-year frequency window. An appeal documenting clinical necessity (structural failure, ridge or anatomic change, abutment loss) succeeds on some plans.
4. Pre-existing condition exclusion on entire prosthesis. Newer commercial plans sometimes exclude prosthetic coverage for arches that were already partially edentulous before the policy started. Verify in the benefit booklet.
5. Documentation gaps. Some carriers require a panoramic radiograph or periodontal charting showing abutment teeth in adequate condition for partial denture retention. A pre-op pano usually clears the request.

The pre-treatment estimate as the workflow checkpoint

For a procedure this expensive with this many possible coverage modifiers, the pre-treatment estimate is the right workflow checkpoint. Submit the planned D5213, get the carrier’s actual payment estimate back, and translate it for the patient as a specific dollar number.

A useful pre-treatment estimate includes:

• The plan’s quoted allowable (whether D5213 or downgraded to D5211).
• The missing-tooth clause adjustment if applicable.
• The standard coinsurance.
• The patient’s expected out-of-pocket dollar amount.

This single document prevents most of the “but my insurance was supposed to cover this” conversations after delivery.

Documentation that supports the claim

The claim needs:

• Date of service (the delivery date).
• Arch designation (maxillary).
• Panoramic radiograph or periodontal charting for carriers that require it.
• Detail on the framework design if requested (most carriers don’t ask).

For the patient record, document:

• Diagnostic impressions and surveyed cast dates.
• Framework design (rests, clasps, indirect retainers, connector type).
• Framework try-in date and fit verification.
• Wax try-in date and patient verification of esthetics.
• Delivery date and post-delivery adjustment schedule.
• Date of last tooth loss on the arch (relevant for missing-tooth clause documentation).

The chart should also document any prosthetic history: prior partial denture, prior bridge, prior immediate temporary partial. This history matters for frequency calculations and for the missing-tooth determination.

Example case

A 58-year-old patient presents with a failing 12-year-old maxillary cast metal partial denture. The framework is fractured at the major connector and the patient reports daily discomfort. The dentist confirms the failure, evaluates the remaining abutment teeth (which are sound), and treatment-plans a new maxillary cast metal partial.

Treatment sequence:

1. Visit 1: diagnostic impressions, abutment evaluation, periodontal charting.
2. Visit 2: framework design impressions, surveyed cast.
3. Visit 3: framework try-in, fit verification.
4. Visit 4: wax try-in with teeth, patient verification.
5. Visit 5: delivery of the new partial.

Billing steps:

1. Verify benefits. Pull the frequency rule (most likely 5 or 7 years) and confirm the prior partial is outside the window (12 years).
2. Check the missing-tooth clause and determine when each replaced tooth was lost relative to current coverage.
3. Submit a pre-treatment estimate and quote the patient an expected out-of-pocket dollar amount.
4. Submit D5213 with arch designation 01 (upper) on the delivery date.
5. Attach a panoramic radiograph and periodontal charting if the carrier requires either.

If the plan applies the alternate-benefit downgrade, the EOB pays at the D5211 allowable and the patient owes the difference. The pre-treatment estimate should have already communicated this.

What to verify before the delivery appointment

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

1. Use D5213 only for cast metal framework partials. A resin-base partial with wrought wire clasps is D5211, not D5213.
2. Bill on the delivery date. The diagnostic, framework, and try-in visits are part of the D5213 workflow.
3. Run a pre-treatment estimate before the first impression. The missing-tooth clause and alternate-benefit downgrade combine to produce out-of-pocket numbers patients need to know in advance.
4. Confirm the frequency rule on every partial case. Five or seven years is typical; the rule and the prior partial date both matter.
5. Document the framework design in the chart. Some carriers ask for it on audit. The lab work order is usually sufficient if filed in the patient record.

If your office sees recurring patient-responsibility complaints on partial denture cases, the cause is usually that the pre-treatment estimate wasn’t done or wasn’t translated into a specific dollar amount. A single workflow change at treatment planning prevents most of those complaints.
