0.000What This Code Means
A blood clot that suddenly forms in the deep veins of the right arm, blocking blood flow.
Coding Tips
- •Distinguish from superficial thrombosis (I82.61x) by confirming deep vein involvement
- •Verify right side is documented and acute onset is confirmed
Clinical Significance
Acute deep vein thrombosis of the upper extremity is a significant vascular event that carries risk of pulmonary embolism and requires immediate anticoagulation therapy. Upper extremity deep vein thrombosis is increasingly recognized, often associated with central venous catheters, pacemaker leads, or thoracic outlet syndrome. This diagnosis captures important vascular disease burden for risk adjustment and signals the need for ongoing monitoring and treatment.
Documentation Requirements
- ✓Provider documentation explicitly stating 'acute' 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 any predisposing factors such as central venous catheter, pacemaker, or thoracic outlet syndrome
Commonly Confused Codes
I82.721 — Chronic version of upper extremity deep vein thrombosis; ensure documentation supports acute rather than chronic presentationI82.A1- — Acute embolism and thrombosis of axillary vein; use the axillary-specific code when that vein is specifically documentedI82.B1- — Acute embolism and thrombosis of subclavian vein; use the subclavian-specific code when that vein is documentedI80.8 — Phlebitis and thrombophlebitis of other sites; this is for venous inflammation with thrombosis, not thromboembolism alone
