ICD-10 Code I87.092 – Postthrombotic syndrome with other complications of left lower extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I87.092 – Postthrombotic syndrome with other complications of left lower extremity
What it is
This code identifies postthrombotic syndrome affecting the left lower extremity with complications other than the classic ulcer or inflammation patterns. It reflects chronic venous damage after prior thrombosis.
Clinical signs
Typical findings include chronic leg swelling, heaviness, pain, skin discoloration, or venous insufficiency changes in the left leg. Clinical features vary; refer to documentation.
When to use this code
Use I87.092 when the record clearly documents postthrombotic syndrome in the left lower extremity and specifies another complication beyond the more specific coded options. Apply it when the condition is chronic and linked to prior thrombosis. Check documentation if the laterality or complication is unclear.
Do not use for
Do not use this code for acute deep vein thrombosis, nonspecific leg edema, or postthrombotic syndrome without left-sided documentation. If the chart only says venous disease, check documentation.
Coding tip
Confirm both laterality and the documented complication before assigning I87.092.
