What This Code Means

A condition where high pressure builds up in the veins of the left leg due to an unknown cause, resulting in an open sore or ulcer on that leg.

Coding Tips

•Pair with an L89 code to fully describe the ulcer's stage and severity
•Ensure documentation specifies the ulcer is related to the venous hypertension, not another cause

Clinical Significance

Chronic venous hypertension (idiopathic) with ulcer of the left lower extremity indicates sustained elevated venous pressure without an identifiable secondary cause, resulting in skin breakdown and chronic ulceration. This condition reflects significant chronic vascular disease requiring ongoing wound care, compression therapy, and monitoring for progression. The ulceration component substantially increases infection risk, hospitalization rates, and overall healthcare resource consumption.

Documentation Requirements

✓Diagnosis of chronic venous hypertension documented
✓Idiopathic etiology specified (no identifiable secondary cause)
✓Laterality documented (left lower extremity)
✓Ulcer presence and characteristics described (size, location, depth, wound bed)
✓Evidence of chronic venous insufficiency (edema, skin changes, hemosiderin staining)
✓Current wound management and compression therapy plan
✓Exclusion of secondary causes documented if applicable

Commonly Confused Codes

I87.311 — Right lower extremity; verify laterality matches documentation I87.33x — Chronic venous hypertension with ulcer AND inflammation; use when both ulcer and inflammation are documented I87.01x — Postthrombotic syndrome with ulcer; use when the venous hypertension is secondary to prior deep vein thrombosis I83.0xx — Varicose veins with ulcer; different underlying pathology, use when ulcer is specifically attributed to varicose veins L97.xxx — Non-pressure chronic ulcer of lower limb; use when the ulcer is not attributable to venous hypertension
