What This Code Means

A blood clot that has formed in the deep veins of the left arm and has persisted over time, potentially blocking blood flow. This is a chronic condition where the clot remains present rather than being a recent occurrence.

Coding Tips

•Verify documentation specifies 'chronic' and 'left upper extremity' to ensure correct code selection, as similar codes exist for acute conditions and other anatomical locations
•Confirm whether the thrombosis is associated with any underlying conditions (such as malignancy, surgery, or immobility) as these may require additional secondary codes

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 left-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

I82.622 — 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
