What This Code Means

A chronic blood clot in the deep veins (veins deeper within the arm) of the right upper arm.

Coding Tips

•Deep vein thrombosis is more clinically significant than superficial; ensure 'deep' is documented
•The '1' suffix indicates right side; verify laterality is clearly stated in the medical record

Clinical Significance

Chronic deep vein thrombosis of the upper extremity indicates a persistent thrombus that has organized and may cause post-thrombotic syndrome with chronic arm swelling, pain, and functional limitation. This condition requires long-term anticoagulation management and monitoring for complications including recurrent thromboembolism. Accurate capture of chronic upper extremity deep vein thrombosis is important for risk adjustment as it reflects ongoing vascular disease burden.

Documentation Requirements

✓Provider documentation explicitly stating 'chronic' deep vein thrombosis (not assumed from duration of treatment)
✓Clinical evidence supporting the diagnosis such as duplex ultrasound, venography, or other imaging results
✓Specific vein location documented (e.g., upper extremity)
✓Documentation confirming right-sided laterality
✓Current treatment plan including anticoagulation therapy and duration
✓Assessment and monitoring notes demonstrating the condition is being actively managed
✓Documentation of chronicity such as 'chronic,' 'old,' 'long-standing,' or history of prior acute deep vein thrombosis that has transitioned to chronic status
✓Documentation of any predisposing factors such as central venous catheter, pacemaker, or thoracic outlet syndrome

Commonly Confused Codes

I82.621 — Acute version of upper extremity deep vein thrombosis; use chronic code only when the condition is long-standing I82.A2- — Chronic embolism and thrombosis of axillary vein; use axillary-specific code when that vein is documented I82.B2- — Chronic embolism and thrombosis of subclavian vein; use subclavian-specific code when that vein is documented I87.01- — Postthrombotic syndrome; a separate sequela condition that may coexist with chronic deep vein thrombosis but is coded additionally
