Postthrom syndrome w oth comp of bilateral low extrm

This code signifies a chronic venous disorder affecting both lower extremities, resulting from a previous deep vein thrombosis (DVT). It encompasses a range of persistent symptoms and signs, such as chronic edema, skin changes (e.g., hyperpigmentation, lipodermatosclerosis), and venous ulcers, that develop after the acute DVT has resolved. The "other complications" aspect indicates manifestations beyond simple pain or swelling.

Assign this code when documentation clearly indicates postthrombotic syndrome affecting both lower limbs, with specific mention of complications other than just pain or edema. This includes conditions like venous stasis dermatitis, venous ulcers, or significant induration and fibrosis. Supporting documentation should detail the history of DVT in both legs and the current chronic venous insufficiency with these specific complications.

• Ensure documentation specifies bilateral lower extremity involvement; otherwise, use unilateral codes.
• Distinguish "other complications" from simple post-thrombotic pain (I87.01-) or swelling (I87.02-).
• Code any associated venous ulcers separately with appropriate L97.x codes, linking them to the postthrombotic syndrome.
