Full Cast Base Metal Crown - CDT Code Guide
Overview
CDT code D2791 refers to the procedure of placing a full cast crown made predominantly of base metal. This type of crown is often used in restorative dentistry to cover and protect a damaged or decayed tooth, restoring its shape, size, and function. The procedure involves preparing the tooth, taking impressions, and fitting the crown securely over the tooth. Typically, this type of crown is chosen for its durability and cost-effectiveness, especially in areas of the mouth where aesthetics are less of a concern, such as the molars. Dental professionals may recommend a full cast predominantly base metal crown in cases where a tooth has been significantly weakened by decay or fracture, ensuring long-term protection and functionality.
When to Use This Code
- When a tooth has extensive decay that compromises its structure.
- For restoring a fractured tooth that cannot be repaired with a filling.
- In cases where a previous crown has failed and needs replacement.
- When a patient requires a durable and cost-effective crown solution.
- For posterior teeth where aesthetics are less critical.
Documentation Requirements
- Detailed clinical notes justifying the need for a crown.
- Pre-operative and post-operative radiographs.
- Patient consent forms detailing the procedure and material used.
- Impression records and laboratory work orders.
- Documentation of any previous restorations on the tooth.
Billing Considerations
When billing for D2791, ensure that the procedure is documented thoroughly to justify the use of a full cast predominantly base metal crown. Be aware of any frequency limitations imposed by insurance carriers, as some may only cover crown replacements every 5-10 years. Common modifiers may include those indicating the tooth number and quadrant. It's important to verify with the patient's insurance provider regarding coverage specifics and any pre-authorization requirements.
