Plan Stipulations vs. Patient Needs: Don’t “Wing” Maryland Bridges

A 19-year-old patient presents with a congenitally missing #10. Orthodontic treatment is complete, but due to finances, a dental implant isn’t a viable option just yet. The doctor decides on a conservative Maryland bridge to restore aesthetics and function while preserving the adjacent healthy tooth structure and the space for tooth #10.

The clinical side is a success, however, there is still the matter of how to handle this from a coding perspective. Does this treatment get billed as a three-unit bridge? A single crown? Some sort of “wing” thing?

In the world of restorative dentistry, the Maryland bridge (also known as a resin-bonded fixed partial denture) is a fantastic tool for situations like the above. Yet for the administrative team, these cases can be a coding puzzle. If the materials don’t match or the quantities are off, the office is potentially looking at a delay in payor reimbursement or a swift dental claim denial.

To keep your revenue cycle healthy and your clinical records precise, let’s break down exactly how to document and report these restorations.

When billing for a Maryland bridge, you aren’t using a single “all-in-one” code. Instead, you are reporting a combination of components:

• The Pontic: The artificial tooth that is replacing the missing one.
• The Retainers (“Wings”): The pieces that bond to the lingual or facial surfaces of the adjacent natural teeth.

A common mistake in Maryland bridge coding is a material mismatch. The pontic material and the wing retainer materials must match. For example, if you submit a porcelain pontic with a metal retainer code, the insurance software will likely flag it for a manual review—or issue a flat-out denial.

• If coding for all porcelain/ceramic (D6245 – Pontic – Porcelain/Ceramic), the office would want to report this using D6548 – Retainer – Porcelain/Ceramic for Resin Bonded Fixed Prosthesis as the “wings.”
• If coding for PFM, the office would use the pontic code based on the type of metal used (as an example, code D6242 – Pontic – Porcelains Fused to Noble Metal) and then report D6545 – Retainer – Cast Metal for Resin Bonded Fixed Prosthesis as the “wings.”
• If coding for resin (D6205 – Pontic – Indirect Resin Based Composite), the office would want to report this using D6549 – Resin Retainer – For Resin Bonded Fixed Prosthesis as the “wings.”

To ensure your claims are processed smoothly, keep these two claim submission tips in mind.

1. Count Your “Wings” for Accurate Reporting: You must report the retainer code (D6548, D6545, or D6549) for each retainer. If you have a traditional two-wing design, you will list the retainer code twice on the claim, or adjust the quantity to “2” on the 2024 ADA Dental Claim Form.
2. Be Aware of the Incurred Liability Date: This is the date a payor is legally liable to consider reimbursement for a service rendered. As with all multi-appointment procedures, whether a payor pays on prep or seat date varies by plan and should be verified prior to claim submission to avoid confusion or claim reimbursement delays.

By aligning your clinical materials with the correct CDT codes, you ensure your practice gets paid accurately and your patients receive the maximum benefit available from their coverage. Beyond the bottom line, this level of administrative precision reduces the friction of claim denials and exhausting back-and-forth appeals, allowing the team to focus on what they do best—delivering exceptional patient care.

When your clinical documentation and your coding work in harmony, you aren’t just submitting a claim; you’re protecting the financial health of your practice and the trust of your patients.
