ICD-10 Code I87.093 – Postthrombotic syndrome with other complications of bilateral lower extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I87.093 – Postthrombotic syndrome with other complications of bilateral lower extremity
What it is
I87.093 identifies postthrombotic syndrome affecting both lower extremities with complications other than the more specific listed forms. It reflects chronic venous damage after prior thrombosis.
Clinical signs
Typical findings include chronic leg swelling, pain, heaviness, skin discoloration, and venous stasis changes after a history of deep vein thrombosis. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record documents postthrombotic syndrome in both legs and the complication is specified as “other” rather than a more specific category. It fits chronic sequelae of prior thrombosis, not an acute clot. Confirm bilateral lower-extremity involvement in the note.
Do not use for
Do not use it for acute deep vein thrombosis, isolated unilateral postthrombotic syndrome, or postthrombotic syndrome with a different documented complication. Check documentation.
Coding tip
Verify both laterality and the exact complication wording before assigning I87.093.
