ICD-10 Code I80.13 – Phlebitis and thrombophlebitis of femoral vein, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I80.13 – Phlebitis and thrombophlebitis of femoral vein, bilateral
What it is
I80.13 identifies inflammation and clot formation in both femoral veins. Use it when the documentation clearly states bilateral femoral vein phlebitis or thrombophlebitis.
Clinical signs
Clinical features may include leg pain, swelling, warmth, tenderness, or a palpable cord. Clinical features vary; refer to documentation, imaging, and the provider’s final diagnosis.
When to use this code
Use this code when the record specifies thrombophlebitis or phlebitis of the femoral vein on both sides. It is appropriate for confirmed bilateral disease, including imaging-supported diagnoses or provider documentation that names both femoral veins.
Code it only when the anatomic site and laterality are documented clearly. If the note says deep vein thrombosis without naming the femoral vein, check documentation before assigning I80.13.
Do not use for
Do not use this code for unilateral femoral vein disease, superficial thrombophlebitis, or unspecified lower-extremity thrombosis. If the location or laterality is unclear, check documentation.
Coding tip
Confirm both the vein location and bilateral laterality in the final provider diagnosis before you assign I80.13.
