ICD-10 Code I87.33 – Chronic venous hypertension (idiopathic) with ulcer and inflammation (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I87.33 – Chronic venous hypertension (idiopathic) with ulcer and inflammation
What it is
This code identifies chronic venous hypertension in the leg veins, with an ulcer and surrounding inflammation. It is used when the condition is idiopathic, meaning no specific cause is documented.
Clinical signs
Typical findings include a chronic lower-extremity venous ulcer with edema, skin discoloration, or stasis changes. Clinical features vary; refer to documentation.
When to use this code
Use I87.33 when the record clearly documents chronic venous hypertension, an active ulcer, and inflammation, and the condition is described as idiopathic. You should ensure the ulcer is linked to venous disease, not another cause. Check documentation if laterality or ulcer details are unclear.
Do not use for
Do not use this code for venous hypertension without an ulcer or without inflammation. It is also not appropriate when the ulcer is due to diabetes, pressure, arterial disease, or another documented cause.
Coding tip
Confirm the provider documents the venous cause and the ulcer/inflammation relationship before assigning I87.33.
