What This Code Means

A chronic blood clot in the deep veins of an upper arm where the specific side is not identified.

Coding Tips

•Query the provider to determine if the clot is in the right or left arm when possible
•This code should be used only when laterality cannot be determined from documentation

Clinical Significance

Chronic deep veins of the upper extremity thrombosis indicates a long-standing vascular condition with persistent clot burden, reflecting ongoing risk for post-thrombotic syndrome, recurrent thromboembolism, and venous insufficiency. This diagnosis captures the sustained complexity of the patient's vascular disease and the need for long-term anticoagulation management, which is important for accurate risk adjustment.

Documentation Requirements

✓Provider documentation explicitly stating chronic embolism or thrombosis of the deep veins of the upper extremity
✓Laterality must be documented (unspecified side) — do not assume from context
✓Clinical findings supporting the diagnosis (e.g., swelling, pain, imaging results such as duplex ultrasound or CT venography)
✓Current treatment plan including anticoagulation therapy type, duration, and monitoring parameters
✓Duration or timeline establishing chronicity (e.g., 'long-standing,' 'diagnosed 6 months ago')
✓Evidence of ongoing monitoring or follow-up imaging confirming persistent thrombus

Commonly Confused Codes

I82.A11-A29 — Embolism and thrombosis of axillary vein; more specific vessel location should be used when documented I82.B11-B29 — Embolism and thrombosis of subclavian vein; more specific vessel location should be used when documented I82.40x-I82.4Yx — Deep vein thrombosis of lower extremity; wrong anatomical region entirely Always query the provider for laterality before defaulting to the unspecified code; right or left-sided codes are preferred
