2025 ICD-10-CM code I80.1

Phlebitis and thrombophlebitis of the femoral vein. This includes the common femoral vein and the deep femoral vein.

Use additional codes to identify any underlying conditions or complications. If the condition is related to pregnancy or childbirth, use codes from the appropriate chapter (O00-O9A).

Medical necessity depends on the severity and potential complications.Treatment aims to prevent clot extension, pulmonary embolism, and post-thrombotic syndrome.

Diagnosis and management typically fall under vascular surgery, internal medicine, or cardiology, depending on the severity and underlying cause.

In simple words: Inflammation or blood clots in the large vein in the thigh (femoral vein).

Inflammation (phlebitis) or inflammation with blood clot formation (thrombophlebitis) in the femoral vein, which is located in the thigh.This condition can affect the common femoral vein or the deep femoral vein.

Example 1: A patient presents with pain, swelling, and redness in the thigh, along with tenderness along the course of the femoral vein.Doppler ultrasound confirms the presence of a deep vein thrombosis (DVT) in the femoral vein. The diagnosis is I80.1., A patient with a history of prolonged immobility develops swelling and discomfort in one thigh.A diagnosis of femoral vein thrombophlebitis is made (I80.1), likely due to the immobility contributing to venous stasis., Post-surgery, a patient experiences localized pain and tenderness in their thigh with redness along the femoral vein without confirmation of clot. The clinician may use I80.1 even if a definitive diagnosis of phlebitis without clot cannot yet be determined definitively without further diagnostic testing.

Documentation should include location (femoral vein, specifying common or deep if applicable), signs and symptoms (pain, swelling, redness, tenderness), and diagnostic results (e.g., Doppler ultrasound, D-dimer).If there's an underlying cause (e.g., recent surgery, trauma, immobility), it should also be documented.
