Chronic venous hypertension w inflammation of unsp low extrm

This code signifies a persistent elevation of venous pressure in an unspecified lower extremity, not attributable to a known cause (idiopathic), and accompanied by inflammatory changes. These inflammatory changes often manifest as redness, swelling, warmth, or pain in the affected limb, distinct from ulceration.

Apply this code when documentation clearly indicates chronic venous hypertension of an unknown origin affecting a lower extremity, with concurrent signs of inflammation. This is appropriate for conditions like venous stasis dermatitis without ulceration, where the underlying cause is idiopathic venous hypertension.

• Ensure documentation specifies "idiopathic" or "primary" venous hypertension to differentiate from secondary causes.
• Do not use this code if an ulcer is present; instead, refer to codes in the I87.33- series for chronic venous hypertension with ulcer.
• Confirm the inflammation is directly related to the venous hypertension and not a separate dermatological condition.
