ICD-10 Code L81.7 – Pigmented purpuric dermatosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L81.7 – Pigmented purpuric dermatosis
What it is
L81.7 identifies pigmented purpuric dermatosis, a benign skin condition marked by chronic capillary leakage and brownish discoloration. Use it when documentation names this disorder specifically.
Clinical signs
Typical findings include petechial or purpuric spots with hemosiderin-related pigmentation, often on the lower legs. Clinical features vary; refer to documentation.
When to use this code
Use L81.7 when the clinician documents pigmented purpuric dermatosis, Schamberg disease, or a similar pigmented purpuric eruption. Apply it when the record supports a chronic purpuric rash rather than a traumatic bruise or vasculitis. Check documentation if the description is nonspecific.
Do not use for
Do not use this code for bruising from injury, thrombocytopenic purpura, or other vasculitic purpura unless the record clearly states pigmented purpuric dermatosis. Do not guess from appearance alone.
Coding tip
Confirm the exact dermatology diagnosis in the assessment, not just “purpura” or “rash,” before assigning L81.7.
