ICD-10 Code I82.71 – Chronic embolism and thrombosis of superficial veins of upper extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.71 – Chronic embolism and thrombosis of superficial veins of upper extremity
What it is
This code identifies a long-standing blood clot or embolic obstruction in a superficial vein of the upper extremity. Use it when documentation specifies chronic involvement rather than an acute event.
Clinical signs
Clinical features vary; refer to documentation. You may see localized arm or hand vein tenderness, swelling, or palpable cord, but the record should support chronic superficial venous thrombosis or embolism.
When to use this code
Use I82.71 when the provider documents chronic thrombosis or embolism affecting a superficial vein in the arm, forearm, or related upper-extremity site. It may also apply when imaging or specialist notes clearly describe an old or persistent clot in a superficial vein.
Choose this code only when the site is upper extremity and the vessel is superficial. If the note says deep vein, acute clot, or history only, check documentation before coding.
Do not use for
Do not use this code for acute superficial thrombophlebitis, deep vein thrombosis, or lower-extremity venous clots. Check documentation if the record only mentions prior thromboembolism without current chronic disease.
Coding tip
Verify both the chronic status and the superficial upper-extremity location before assigning I82.71.
