Open bite of other specified part of neck, sequela

This code describes the long-term effects or complications arising from an open bite wound to a specific, but not otherwise classified, area of the neck. These sequelae can include chronic pain, scarring, nerve damage, restricted range of motion, or other persistent issues directly attributable to the original injury. This code is used when the acute phase of the injury has passed, and the patient is presenting for treatment of these residual conditions.

Use this code when documenting the late effects of an open bite to the neck, such as a bite from an animal or human, where the specific site is not detailed enough for more precise coding (e.g., not explicitly the larynx, pharynx, or trachea). Documentation should clearly state that the current condition is a "sequela" or "late effect" of a previous open bite and specify the affected area of the neck. This code is appropriate for follow-up visits addressing chronic issues stemming from the initial injury.

• Always use this code with an external cause code (V00-Y99) to identify the cause of the original bite, if known.
• Ensure documentation explicitly states the condition is a "sequela" or "late effect" and links it to a prior open bite.
• Do not use this code for acute open bite injuries; those require codes from the S11.80-S11.82 series.
