Understanding Dental Code D6752

When to Use D6752 dental code

The D6752 dental code refers to a retainer crown—specifically, a porcelain fused to noble metal crown used as part of a fixed partial denture (bridge). This CDT code is appropriate when a patient requires a bridge and the retainer (anchor) crown is fabricated using porcelain fused to a noble metal alloy. Use D6752 only when the clinical scenario matches these material and prosthetic requirements. Proper code selection ensures accurate claim processing and minimizes denials.

Documentation and Clinical Scenarios

Accurate documentation is essential for successful reimbursement. For D6752, include the following in the patient record and claim submission:

• Clinical notes describing the need for a fixed partial denture and the condition of abutment teeth.
• Radiographs or intraoral images supporting the necessity for a bridge and the use of a retainer crown.
• Material specifications confirming that the crown is porcelain fused to noble metal.
• Pre-operative and post-operative documentation to demonstrate treatment progression.

Common clinical scenarios include replacing a missing tooth with a bridge where the abutment tooth is restored with a porcelain fused to noble metal crown. If a different material is used, refer to the appropriate CDT code, such as D6750 for porcelain fused to high noble metal or D6751 for base metal.

Insurance Billing Tips

To maximize reimbursement and reduce claim delays for D6752:

• Verify benefits before treatment to confirm bridge and crown coverage, frequency limitations, and material restrictions.
• Submit pre-authorizations when required, including all supporting documentation and radiographs.
• Use precise narratives in the claim to explain the clinical need for a retainer crown and the choice of materials.
• Track EOBs (Explanation of Benefits) and follow up on denied or underpaid claims with timely appeals, referencing documentation and industry guidelines.
• Coordinate benefits if the patient has dual insurance, ensuring correct primary/secondary submission order.

Staying current with payer policies and CDT updates helps prevent common billing errors and supports a healthy accounts receivable (AR) cycle.

Example Case for D6752

A 52-year-old patient presents with a missing lower first molar. The adjacent teeth are healthy and suitable as abutments. After discussing options, the provider recommends a three-unit bridge with retainer crowns on both abutment teeth. The treatment plan specifies porcelain fused to noble metal for optimal aesthetics and durability. The dental team documents the clinical findings, obtains pre-op radiographs, and submits a pre-authorization with the D6752 code. Upon approval, the procedure is completed, and the claim is submitted with detailed narratives and post-op images. The insurance carrier processes the claim without delay, and the practice receives prompt payment.

By following best practices for documentation and billing, dental teams can ensure smooth reimbursement for D6752 and maintain compliance with insurance requirements.
