ICD-10 Code I80.11 – Phlebitis and thrombophlebitis of right femoral vein (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I80.11 – Phlebitis and thrombophlebitis of right femoral vein
What it is
I80.11 identifies inflammation of the right femoral vein with associated clot formation. Use it when documentation states phlebitis or thrombophlebitis in that specific deep vein.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include unilateral thigh pain, swelling, tenderness, warmth, or a palpable cord, but the diagnosis should match the provider’s documented assessment.
When to use this code
Use this code when the provider documents phlebitis or thrombophlebitis involving the right femoral vein. It is appropriate for confirmed deep vein inflammation with thrombosis in that location. If the note only says “DVT” without laterality or vein detail, check documentation.
Do not use for
Do not use I80.11 for superficial thrombophlebitis, other leg veins, or unspecified lower-extremity thrombosis. If the record does not identify the right femoral vein, code more specifically only when documentation supports it.
Coding tip
Always verify laterality and the exact vein named in the provider’s note before assigning I80.11.
