ICD-10 Code I82.569 – Chronic embolism and thrombosis of unspecified calf muscular vein (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.569 – Chronic embolism and thrombosis of unspecified calf muscular vein
What it is
This code identifies a chronic blood clot or embolic blockage in a calf muscular vein, but the exact side is not specified. Use it when the record documents an ongoing or past clot in a calf muscle vein.
Clinical signs
Findings may include calf pain, swelling, tenderness, or a history of venous thrombosis. Clinical features vary; refer to documentation and imaging or vascular assessment when available.
When to use this code
Use this code when the provider documents chronic embolism or thrombosis involving an unspecified calf muscular vein and does not name the right or left side. It may also fit follow-up notes for persistent or residual clot in that vein. If the record only says “DVT” without location or chronicity, check documentation.
Do not use for
Do not use it for acute calf vein thrombosis, superficial thrombophlebitis, or thrombosis in a different venous site. If the side is documented, choose the more specific code.
Coding tip
Code chronicity and laterality exactly as documented; if either is missing, verify the chart before assigning I82.569.
