D9230

Nitrous Oxide Single Agent - CDT Code Guide

Adjunctive/Anesthesia

Overview

CDT code D9230 refers to the administration of nitrous oxide as a single agent for analgesia in dental procedures. This inhalation method is commonly used to manage pain and anxiety during dental treatments, providing a calming effect for patients. Nitrous oxide, often known as 'laughing gas,' is a safe and effective option for patients who experience dental anxiety or require mild sedation for procedures such as fillings, extractions, or periodontal therapy. Dental professionals use this code to document the use of nitrous oxide when it is the sole agent employed for sedation purposes. The procedure involves the patient inhaling the gas through a mask, which takes effect quickly and allows for a rapid recovery post-treatment.

When to Use This Code

Patients experiencing anxiety or fear during dental procedures
Minor dental surgeries requiring mild sedation
Children or adults with special needs who may not cooperate during treatment
Procedures where local anesthesia is insufficient
Patients with a low pain threshold undergoing restorative work

Documentation Requirements

Patient consent for use of nitrous oxide
Detailed record of the procedure including duration and concentration of nitrous oxide used
Patient's response and any adverse reactions
Pre- and post-procedure vital signs
Justification for the use of nitrous oxide as a single agent

Billing Considerations

When billing for D9230, ensure that the use of nitrous oxide is justified as medically necessary. Check with insurance providers for coverage policies as some may not cover nitrous oxide for all procedures. Frequency limitations may apply, and it is important to document the necessity clearly. Common modifiers may include those indicating the type of sedation or anesthesia used.
