Re-cement or Re-bond Crown - CDT Code Guide
Overview
CDT code D2920 is used for the procedure of re-cementing or re-bonding a crown. This restorative service is necessary when a crown becomes loose or detached from a tooth but is still in good condition and can be reused. The procedure involves cleaning the crown and the tooth surface, applying a dental adhesive, and securely reattaching the crown. This service is typically performed when the crown itself is undamaged, but the bond between the crown and the tooth has failed. It is a cost-effective solution compared to fabricating a new crown and is commonly used in cases where the underlying tooth structure is still sound.
When to Use This Code
- When a crown has become loose but is still intact and undamaged.
- In cases where the original cement has failed and the crown needs reattachment.
- When a patient reports discomfort or instability in a crowned tooth.
- Following trauma that has dislodged a crown without damaging it.
- During routine dental check-ups if a loose crown is detected.
Documentation Requirements
- Detailed patient records indicating the need for re-cementation.
- Documentation of the original crown placement date and materials used.
- Clinical notes describing the condition of the crown and tooth.
- Patient consent for the re-cementation procedure.
- Photographic evidence or radiographs if applicable.
- Record of the type of cement or adhesive used.
Billing Considerations
When billing for D2920, it is important to note that this code is typically not covered for routine maintenance or cleaning of crowns. Insurance plans may have specific frequency limitations, often covering this procedure only once per crown per year. Common modifiers may include those indicating the quadrant or arch. It is crucial to verify with the patient's insurance provider for specific coverage details and any prior authorization requirements.
