ICD-10 Code I82.629 – Acute Embolism and Thrombosis of Deep Veins of Unspecified Upper Extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.629 – Acute embolism and thrombosis of deep veins of unspecified upper extremity
What it is
This code identifies an acute blood clot or embolus in a deep vein of the upper extremity when the affected side is not documented. Use it for new-onset deep venous thrombosis involving the arm or shoulder region.
Clinical signs
Common findings include arm swelling, pain, warmth, tenderness, and visible superficial venous distention. Clinical features vary; refer to documentation and imaging or other provider-confirmed evidence of upper-extremity deep vein thrombosis.
When to use this code
Use this code when the record states an acute deep vein thrombosis or embolism in an upper-extremity deep vein, but does not specify right or left. It also fits documentation that confirms the condition without naming a more precise vein location.
If the provider documents a chronic clot, a superficial vein problem, or a different extremity site, this code is not appropriate. Check documentation carefully for acuity and laterality before assigning I82.629.
Do not use for
Do not use this code for superficial thrombophlebitis, chronic venous thrombosis, or lower-extremity DVT. If the note specifies a right or left upper extremity, choose the more specific code instead.
Coding tip
Verify both acuity and laterality in the provider note; unspecified upper-extremity DVT should be coded only when the side is not documented.
