Open bite of larynx, subsequent encounter

This code signifies an open wound of the larynx, such as a laceration or puncture, that has occurred due to a bite. The injury involves a break in the skin and underlying laryngeal tissue, exposing deeper structures. This specific code indicates that the patient is receiving follow-up care for this previously diagnosed injury.

Use this code for patients presenting for subsequent treatment of an open bite to the larynx, such as wound care, medication management, or monitoring for complications. Documentation should clearly state "subsequent encounter" or indicate follow-up care for the initial injury. This code is appropriate after the initial treatment of the acute injury has been rendered.

• Ensure documentation specifies "subsequent encounter" for the open bite.
• Distinguish from initial encounter codes (ending in A) and sequela codes (ending in S).
• Always code the external cause of the injury (e.g., W54.0XXD for dog bite) in addition to the injury code.
