Postthrom syndrome w ulcer and inflammation of l low extrem

This code signifies a chronic venous insufficiency affecting the left lower extremity, specifically resulting from a previous deep vein thrombosis (DVT). The condition is characterized by the presence of both an ulcer and inflammation, indicating significant skin and tissue damage due to impaired venous return. It represents a severe manifestation of postthrombotic syndrome.

Apply this code when documentation clearly indicates a diagnosis of postthrombotic syndrome in the left lower extremity, with explicit mention of both ulceration and inflammation. This typically occurs in patients with a history of DVT who subsequently develop chronic leg pain, swelling, skin changes, and open sores. Supporting documentation should detail the location (left lower extremity) and the specific complications (ulcer and inflammation).

• Ensure the documentation specifies both ulceration and inflammation; if only one is present, a different subcategory code would be appropriate.
• Verify the laterality (left lower extremity) is clearly documented.
• Do not confuse this with acute DVT or other forms of venous insufficiency without a clear history of DVT and the specified complications.
