ICD-10 Code I82.552 – Chronic Embolism and Thrombosis of Left Peroneal Vein (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.552 – Chronic embolism and thrombosis of left peroneal vein
What it is
I82.552 identifies a chronic blood clot or embolic obstruction in the left peroneal vein, a deep vein in the lower leg. Use it when the record clearly states the condition is chronic and left-sided.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings may include persistent leg swelling, pain, tenderness, or prior imaging showing chronic venous obstruction in the left peroneal vein.
When to use this code
Use this code when the provider documents chronic embolism or thrombosis specifically in the left peroneal vein. It may apply to follow-up visits, ongoing management, or imaging reports that confirm an old, persistent clot. If the side or chronicity is not stated, check documentation.
Do not use for
Do not use it for acute deep vein thrombosis, unspecified lower-extremity thrombosis, or thrombosis in a different vein. If the record does not clearly identify the left peroneal vein, choose a more accurate code or check documentation.
Coding tip
Confirm both laterality and chronic status in the note, because missing either detail can change the correct ICD-10 code.
