Pigmented purpuric dermatosis
ICD-10 L81.7 is a billable code used to indicate a diagnosis of pigmented purpuric dermatosis.
Pigmented purpuric dermatosis (PPD) is a chronic skin condition characterized by the appearance of reddish-brown or purplish spots on the skin, primarily affecting the lower extremities. The lesions are often asymptomatic but can be associated with mild pruritus. PPD is thought to result from capillary leakage and extravasation of red blood cells, leading to hemosiderin deposition in the dermis. The condition typically presents in adults, particularly those with a history of venous insufficiency or other vascular disorders. The lesions may progress over time, becoming more extensive and darker, but they usually do not lead to serious complications. Diagnosis is primarily clinical, supported by a thorough patient history and physical examination. Skin biopsy may be performed to rule out other conditions, such as vasculitis or dermatitis. Differential diagnoses include other forms of purpura, such as Schamberg's disease and other pigmented lesions. Understanding the underlying vascular changes is crucial for management and patient education.

L81.7 specifically covers pigmented purpuric dermatosis, which includes variants like Schamberg's disease and other similar conditions characterized by pigmentary changes and purpura.
L81.7 should be used when the clinical presentation aligns with pigmented purpuric dermatosis, particularly when distinguishing from other types of purpura or skin pigmentation disorders.
Documentation should include a detailed clinical history, physical examination findings, and, if applicable, results from any skin biopsies or laboratory tests that support the diagnosis of pigmented purpuric dermatosis.
