ICD-10 Code I82.501 – Chronic Embolism and Thrombosis of Unspecified Deep Veins of Right Lower Extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.501 – Chronic embolism and thrombosis of unspecified deep veins of right lower extremity
What it is
This code identifies a chronic blood clot or embolic blockage in deep veins of the right lower leg, with the exact vein not specified. Use it when the condition is documented as longstanding or chronic.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include persistent leg swelling, pain, heaviness, skin discoloration, or a history of prior deep vein thrombosis in the right leg.
When to use this code
Use I82.501 when the provider documents chronic embolism or thrombosis in unspecified deep veins of the right lower extremity. It is appropriate for follow-up visits, ongoing management, or when the diagnosis remains active and the right side is clearly identified.
Choose this code only when the record does not name a specific deep vein. If the documentation says acute, recurrent, or specifies another lower-extremity vein, code to the documented condition instead.
Do not use for
Do not use this code for acute DVT, superficial vein thrombosis, or embolism in a different extremity. Check documentation if the laterality or chronicity is unclear.
Coding tip
Verify both chronic status and right-sided laterality before assigning I82.501.
