Inlay Metallic Two Surfaces - CDT Code Guide
Overview
CDT code D2520 refers to a restorative dental procedure involving the placement of a metallic inlay covering two surfaces of a tooth. This procedure is typically used when a tooth is too damaged for a filling but not damaged enough to require a full crown. The metallic inlay is custom-made to fit the cavity and restore the tooth's function and aesthetics. Inlays are often used in molars and premolars where chewing forces are greatest. This procedure helps in preserving more of the natural tooth structure compared to a crown.
When to Use This Code
- When a tooth has moderate decay that cannot be restored with a filling.
- In cases where the tooth structure is compromised but a full crown is not necessary.
- For patients who prefer a durable and long-lasting restoration.
- When the patient has a history of recurrent decay and requires a more robust restoration.
- In situations where aesthetics are less of a concern compared to strength and durability.
Documentation Requirements
- Detailed chart notes describing the extent of the decay and the surfaces involved.
- Pre-operative and post-operative radiographs to support the necessity of the procedure.
- A narrative report explaining why a metallic inlay was chosen over other restorative options.
- Patient consent forms indicating understanding and acceptance of the procedure.
- Documentation of any previous restorations and their failures, if applicable.
Billing Considerations
When billing for D2520, ensure that the procedure is not performed more frequently than necessary, as insurance may have limitations on the frequency of inlay restorations. Common modifiers include those indicating the quadrant of the mouth. Verify with the patient's insurance for coverage specifics, as some plans may prefer alternative materials or procedures.
