Postthrom syndrome w ulcer and inflam of bilateral low extrm

This code signifies a chronic complication following deep vein thrombosis (DVT) affecting both lower extremities, characterized by persistent venous insufficiency leading to skin ulceration and inflammatory changes. It indicates a severe form of postthrombotic syndrome (PTS) where the venous hypertension has progressed to tissue breakdown and inflammation in both legs.

Use this code when documentation clearly states the presence of postthrombotic syndrome in both lower extremities, specifically noting the presence of active venous ulcers and signs of inflammation (e.g., erythema, warmth, induration). This typically applies to patients with a history of DVT who present with chronic bilateral leg swelling, pain, skin discoloration, and open sores with surrounding inflammatory reactions.

• Ensure documentation specifies "bilateral" involvement and explicitly mentions both "ulcer" and "inflammation."
• Do not use this code if only one lower extremity is affected; refer to I87.031 or I87.032.
• Code any underlying DVT (e.g., I82.4-) or other associated conditions separately, if still active and relevant.
