Cutis rhomboidalis nuchae

This code represents a specific form of elastosis characterized by thickened, yellowish, and leathery skin on the posterior neck, often with a rhomboidal or diamond-shaped pattern. It is a chronic, benign dermatological condition primarily caused by prolonged sun exposure and is considered a severe form of solar elastosis.

Use this code when documentation clearly indicates the presence of cutis rhomboidalis nuchae, typically observed in older individuals with a history of significant sun exposure. The diagnosis is usually made clinically based on the characteristic appearance and location of the skin changes.

• Differentiate from other forms of solar elastosis or actinic damage; this code is specific to the nuchal region and its characteristic pattern.
• Ensure the physician's documentation explicitly states "cutis rhomboidalis nuchae" or provides a clear clinical description matching the condition.
• This is a diagnosis code, not a code for a procedure or service.
