Why choose a coronectomy over a full extraction?

A coronectomy is chosen when there is a high risk of nerve damage from a full extraction, particularly with teeth near the inferior alveolar nerve.

Is a coronectomy covered by insurance?

Coverage varies by insurance provider. It's important to check with the patient's insurance and possibly obtain pre-authorization.

What are the risks of a coronectomy?

While it reduces the risk of nerve damage, a coronectomy can still lead to complications like infection or root migration.

How long is the recovery after a coronectomy?

Recovery time varies, but patients typically experience less discomfort and faster healing compared to full extractions.

Coronectomy Intentional Partial Tooth Removal - CDT Code Guide

Oral & Maxillofacial Surgery/Extractions (Includes Local Anesthesia, Suturing If Needed, and Routine Postoperative Care)

Overview

CDT code D7251 refers to the coronectomy procedure, which involves the intentional partial removal of an impacted tooth. This procedure is specifically used when there is a high risk of neurovascular complications if the entire tooth is extracted. Typically, coronectomy is performed on impacted wisdom teeth that are in close proximity to the inferior alveolar nerve. By removing only the crown of the tooth and leaving the roots intact, dental professionals can minimize the risk of nerve damage, which can lead to numbness or other sensory issues in the jaw. This procedure is a critical option in oral and maxillofacial surgery, providing a safer alternative for patients with complex dental anatomy.

When to Use This Code

When an impacted wisdom tooth is in close proximity to the inferior alveolar nerve.
In cases where full extraction poses a high risk of nerve damage.
For patients with complex dental anatomy that increases surgical risks.
When the patient has a history of nerve-related complications from dental procedures.
In scenarios where preservation of nerve function is a priority.

Documentation Requirements

Detailed patient history and examination notes indicating the need for a coronectomy.
Radiographic evidence showing the proximity of the tooth to the nerve.
Clinical notes explaining the decision to perform a partial rather than full extraction.
Informed consent documentation from the patient acknowledging the risks and benefits.
Postoperative care instructions provided to the patient.
Follow-up appointment details for monitoring recovery and potential complications.

Billing Considerations

When billing for D7251, it is important to note that this code is specific to impacted teeth only. Ensure that the procedure is documented thoroughly to justify the partial removal due to neurovascular risks. Common modifiers may include those indicating the specific quadrant of the mouth. Insurance coverage can vary, so pre-authorization may be necessary. Frequency limitations typically do not apply, but documentation must clearly support the clinical decision.
