Vascular disorders of skin

This code represents a range of conditions affecting the blood vessels within the skin, leading to visible cutaneous manifestations. These disorders can involve arteries, veins, or capillaries, resulting in various lesions such as telangiectasias, livedo reticularis, or purpura. The underlying pathology often relates to abnormal vessel structure, function, or inflammation.

Use this code when documentation indicates a diagnosed vascular disorder primarily affecting the skin, such as cutaneous vasculitis (unspecified), livedo reticularis, or essential telangiectasias. Supporting documentation should clearly describe the vascular nature of the skin condition and rule out systemic causes or specific inflammatory processes.

• Differentiate from inflammatory skin conditions (e.g., dermatitis) unless the inflammation is secondary to a primary vascular issue.
• Avoid using this code if a more specific diagnosis for the vascular disorder is available (e.g., specific types of vasculitis coded elsewhere).
• Ensure documentation specifies the skin as the primary site of the vascular involvement.
