Acquired absence of other part of head and neck

📋Clinical Description

This code signifies the permanent loss or removal of a non-dental anatomical structure from the head or neck region that was present at birth. This absence is due to an acquired cause, such as surgery, trauma, or disease, rather than a congenital anomaly.

🎯When to Use

Apply this code when documenting the acquired absence of structures like the nose, ear (pinna), or larynx. It is appropriate for patients who have undergone surgical removal of these parts, or who have lost them due to injury or disease processes.

💡Coding Tips

Ensure the documentation clearly states the absence is acquired, not congenital.
Specify the exact anatomical part of the head or neck that is absent if possible, though this code is for "other" parts.
Remember the Excludes2 note and do not use this code for missing teeth.
