Overview of CPT Code 21089:Removal of impacted tooth

CPT Code 21089 refers to the surgical removal of an impacted tooth, typically a wisdom tooth, that is unable to fully emerge through the gums. This procedure is often necessary when the tooth is causing pain, infection, or other dental issues.

When CPT Code 21089 is Used?

This code is applicable in various clinical scenarios, including:

• Presence of an impacted wisdom tooth causing pain or discomfort.
• Infection or abscess formation around the impacted tooth.
• Cyst formation associated with the impacted tooth.
• Impacted teeth causing damage to adjacent teeth.
• Preparation for orthodontic treatment requiring tooth removal.

Symptoms Indicating This Procedure

Patients may report several symptoms that indicate the need for this procedure, including:

• Severe pain in the back of the mouth.
• Swelling and tenderness in the gums.
• Difficulty opening the mouth.
• Bad breath or an unpleasant taste in the mouth.
• Infection signs such as fever or swollen lymph nodes.

Causes and Risk Factors

Several factors can contribute to the development of impacted teeth, including:

• Genetic predisposition to dental crowding.
• Jaw size that is too small to accommodate all teeth.
• Early loss of primary teeth leading to misalignment.
• Poor oral hygiene leading to infections.
• Age, as wisdom teeth typically emerge in late adolescence or early adulthood.

Diagnostic Tests Before Procedure

Before the procedure, several diagnostic tests may be performed to assess the condition of the impacted tooth:

• Dental X-rays to visualize the position of the impacted tooth.
• Panoramic X-rays to assess the surrounding structures.
• Clinical examination to evaluate symptoms and oral health.

Procedure Description

The removal of an impacted tooth typically follows these steps:

• Patient is given local anesthesia or sedation.
• An incision is made in the gum tissue to expose the tooth.
• Bone covering the tooth may be removed if necessary.
• The tooth is carefully extracted, sometimes in pieces.
• The site is cleaned, and sutures may be placed if needed.

Preparation for the Procedure

Patients should follow these steps to prepare for the procedure:

• Consult with the dentist about medications and health history.
• Avoid eating or drinking for several hours before the procedure.
• Arrange for transportation home post-surgery if sedation is used.
• Follow any specific instructions provided by the dental office.

Recovery and Aftercare

Post-procedure recovery typically involves:

• Resting for the first 24 hours after surgery.
• Applying ice packs to reduce swelling.
• Taking prescribed pain medications as directed.
• Avoiding hard or chewy foods for several days.
• Maintaining oral hygiene while avoiding the surgical site.

Possible Complications

While generally safe, this procedure may have risks, including:

• Infection at the extraction site.
• Dry socket, a painful condition post-extraction.
• Nerve damage leading to numbness or tingling.
• Excessive bleeding.
• Damage to adjacent teeth or structures.
