Postthrom syndrome w/o complications of bilateral low extrm

This code signifies the presence of postthrombotic syndrome (PTS) affecting both lower extremities, characterized by chronic venous insufficiency symptoms such as pain, edema, and skin changes, but without evidence of ulceration, varicose veins, or other specified complications. It represents a long-term sequela of deep vein thrombosis (DVT) in both legs.

Use this code when documentation clearly indicates a diagnosis of postthrombotic syndrome in both lower extremities, and specifically states the absence of complications like venous ulcers, severe varicose veins, or other specified issues. This code is appropriate for patients experiencing chronic symptoms of PTS bilaterally without these more severe manifestations.

• Ensure documentation explicitly states "without complications" or similar language to support this specific code.
• Do not use this code if any complications, such as venous ulcers (L97.-) or severe varicose veins (I83.-), are present; instead, use the appropriate complicated PTS code.
• Confirm that both lower extremities are affected; if only one leg is involved, use the unilateral code.
