ICD-10 Code I82.703 – Chronic Embolism and Thrombosis of Unspecified Veins of Upper Extremity, Bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.703 – Chronic embolism and thrombosis of unspecified veins of upper extremity, bilateral
What it is
This code identifies a long-standing blood clot or embolic blockage in unspecified veins of both upper extremities. Use it when the record documents chronic venous thrombosis or embolism affecting both arms, but does not name a specific vein.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include arm swelling, pain, heaviness, or superficial venous prominence, with imaging or prior history supporting chronic venous obstruction.
When to use this code
Use I82.703 when the provider clearly documents chronic thrombosis or embolism in unspecified veins of both upper extremities. It is appropriate when laterality is bilateral and the vein involved is not specified in the note.
Choose this code for established, not acute, venous disease of the arms. Check documentation if the record mentions catheter-related thrombosis, acute DVT, or a more specific vein location.
Do not use for
Do not use this code for acute upper-extremity thrombosis, unilateral disease, or thrombosis of a named vein. Check documentation if the diagnosis is superficial thrombophlebitis or another nonvenous condition.
Coding tip
Confirm both chronicity and bilateral involvement before assigning I82.703, and code a more specific vein when the documentation supports it.
