Webbing of neck

This code describes the congenital anomaly characterized by redundant skin folds or a short, broad neck, often extending from the mastoid region to the acromion. It is a physical manifestation frequently associated with various genetic syndromes.

Use this code when documentation explicitly states "webbing of neck" or "pterygium colli." This condition is commonly observed in patients with Turner syndrome, Noonan syndrome, or Klippel-Feil syndrome.

• Differentiate from generalized skin redundancy or loose neck skin not specifically described as "webbing."
• Always code any underlying genetic syndrome or associated congenital anomalies if documented.
• Review physician notes for terms like "pterygium colli" as a synonym for neck webbing.
