Postthrom syndrome w inflammation of bilateral low extrm

This code signifies a chronic complication following deep vein thrombosis (DVT) affecting both lower extremities, characterized by persistent symptoms such as pain, swelling, skin changes, and the presence of inflammation. It indicates ongoing venous hypertension and damage to the venous valves, leading to impaired venous return.

Use this code when documentation clearly states postthrombotic syndrome affecting both lower extremities, specifically noting the presence of inflammation. This typically presents with erythema, warmth, and tenderness in addition to the classic signs of PTS. Supporting documentation would include physician notes detailing bilateral lower extremity symptoms consistent with PTS and objective findings of inflammation.

• Ensure documentation explicitly states "bilateral" involvement and the presence of "inflammation" to support this specific code.
• Distinguish from I87.01- (postthrombotic syndrome without inflammation) and codes for unilateral involvement.
• Consider sequencing this code after a DVT code (I82.-) if the DVT is still active or being treated, though PTS is a chronic sequela.
