Webbing of neck

This code describes the presence of redundant skin folds or a web-like appearance of the neck, often extending from the mastoid region to the acromion. This congenital anomaly, also known as pterygium colli, can restrict neck movement and may be associated with underlying genetic syndromes.

Use this code when documentation clearly indicates webbing of the neck as a primary or secondary diagnosis. This condition is frequently observed in genetic disorders such as Turner syndrome or Noonan syndrome, though it can also occur in isolation. Supporting documentation should include physical exam findings describing the neck webbing.

• Do not confuse with redundant skin folds of the neck due to obesity or aging, which would be coded differently.
• Always code any associated genetic syndromes or congenital anomalies if documented.
• Consider laterality if specified, though webbing of the neck is typically bilateral.
