0.000What This Code Means
A chronic condition where high pressure in the veins of both legs causes skin ulcers due to poor circulation, with no identifiable underlying cause.
Coding Tips
- •Verify documentation specifies bilateral involvement; if only one leg is affected, use a more specific code
- •Ensure ulcer severity and stage are documented separately if required by your facility's coding standards
Clinical Significance
Chronic venous hypertension (idiopathic) with ulcer of the bilateral 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 (bilateral 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/I87.312 — Unilateral codes; use bilateral only when both legs are affectedI87.33x — Chronic venous hypertension with ulcer AND inflammation; use when both ulcer and inflammation are documentedI87.01x — Postthrombotic syndrome with ulcer; use when the venous hypertension is secondary to prior deep vein thrombosisI83.0xx — Varicose veins with ulcer; different underlying pathology, use when ulcer is specifically attributed to varicose veinsL97.xxx — Non-pressure chronic ulcer of lower limb; use when the ulcer is not attributable to venous hypertension
