Postthrombotic syndrome w/o complications of unsp extremity

This code signifies a chronic condition resulting from a previous deep vein thrombosis (DVT), characterized by symptoms such as pain, swelling, and skin changes in an extremity. It specifically indicates that there are no documented complications like ulceration or severe venous claudication, and the affected limb is not specified.

Apply this code when documentation confirms a diagnosis of postthrombotic syndrome without any specified complications (e.g., ulcer, stasis dermatitis, venous claudication) and the affected extremity is not clearly identified (e.g., "postthrombotic syndrome of leg" without specifying left or right). This code is appropriate when the physician explicitly states "postthrombotic syndrome without complications" or similar.

• Avoid using this code if specific complications (e.g., ulceration, stasis dermatitis) are documented; instead, choose a more specific code from the I87.0 series.
• Always strive for greater specificity regarding the affected extremity (e.g., I87.011 for right lower extremity) if documented.
• This code is for the sequela of DVT, not the acute DVT itself. Ensure the DVT event is in the past.
