Postthrombotic syndrome w inflammation of l low extrem

This code signifies a chronic condition affecting the left lower extremity, characterized by persistent symptoms such as pain, swelling, skin changes, and ulceration, which develop after a deep vein thrombosis (DVT). The "inflammation" component indicates an active inflammatory process contributing to the patient's symptoms.

Apply this code when documentation clearly states postthrombotic syndrome affecting the left lower extremity, specifically noting signs or symptoms of inflammation (e.g., erythema, warmth, tenderness). This code is appropriate for patients with a history of DVT who now present with chronic venous insufficiency and inflammatory manifestations in the affected limb.

• Ensure documentation specifies "left" lower extremity; laterality is crucial for accurate coding.
• Distinguish from acute DVT (I82.4-); this code represents a chronic sequela.
• Look for terms like "post-phlebitic syndrome" or "venous insufficiency secondary to DVT" with inflammatory signs.
