Phlebitis and thrombophlebitis of right femoral vein

Phlebitis and thrombophlebitis of the right femoral vein is a clinical condition characterized by inflammation of the vein wall (phlebitis) and the concurrent formation of a blood clot (thrombosis) within the femoral vein of the right lower extremity. As a major deep vein of the thigh, the femoral vein is a critical component of the deep venous system; thus, this condition is classified as a form of Deep Vein Thrombosis (DVT). The inflammatory process can cause significant localized discomfort and swelling. The primary clinical concern is the risk of the thrombus dislodging and migrating through the venous circulation to the pulmonary arteries, resulting in a pulmonary embolism (PE), a potentially life-threatening complication. Management typically involves systemic anticoagulation therapy to prevent clot propagation and embolization, alongside compression therapy and monitoring for signs of post-thrombotic syndrome.

Clinical Symptoms

  • Pain and tenderness along the course of the right femoral vein
  • Swelling (edema) of the right thigh and potentially the entire right leg
  • Warmth over the affected area in the right thigh
  • Erythema (redness) of the skin overlying the femoral vein
  • Palpable, firm, cord-like structure beneath the skin of the thigh
  • Increased skin temperature of the right lower extremity compared to the left
  • Low-grade fever
  • Pain that worsens with walking or standing
  • Visible distension of superficial veins in the right leg

Common Causes

  • Venous stasis due to prolonged immobility (e.g., bed rest, long-duration travel, or paralysis)
  • Recent orthopedic surgery, particularly of the hip or knee
  • Vascular endothelial injury from trauma or intravenous catheters
  • Malignancy (paraneoplastic hypercoagulability)
  • Inherited thrombophilia (e.g., Factor V Leiden, Prothrombin G20210A mutation, Protein C or S deficiency)
  • Acquired hypercoagulable states (e.g., Antiphospholipid Syndrome)
  • Pregnancy and the postpartum period
  • Use of oral contraceptives or hormone replacement therapy
  • Obesity
  • Advanced age

Documentation & Coding Tips

Specify the exact anatomical location and laterality to ensure alignment with I80.211.

Example: Patient presents with persistent right lower extremity edema and pain. Duplex ultrasound confirms acute phlebitis and thrombophlebitis of the right femoral vein. This deep vein involvement requires immediate anticoagulation. Condition is primary and not related to recent surgery.

Billing Focus: Documentation must specify the right side and the femoral vein specifically rather than general lower leg or superficial veins.

Clarify the depth of the vein as the femoral vein is a deep vein despite its occasionally misleading name.

Example: Evaluation of right thigh pain reveals deep vein thrombosis located in the right femoral vein. Note: This refers to the deep system, not a superficial tributary. Patient has history of Factor V Leiden deficiency which increases recurrence risk.

Billing Focus: Distinguishing between deep and superficial systems is critical as superficial phlebitis (I80.01) maps differently than deep (I80.211).

Document the presence or absence of associated pulmonary embolism to capture the full scope of the vascular event.

Example: Patient diagnosed with phlebitis and thrombophlebitis of right femoral vein. CT pulmonary angiography negative for pulmonary embolism. Patient is hemodynamically stable and will begin Eliquis therapy.

Billing Focus: Ensures that additional codes for embolism (I26 series) are either appropriately excluded or included.

Note any provocative factors such as recent surgery, trauma, or immobilization.

Example: Right femoral vein thrombophlebitis diagnosed post-operatively following right total hip arthroplasty. Patient remained immobilized for 48 hours post-procedure. Anticoagulation initiated with Lovenox bridge to Warfarin.

Billing Focus: Identifies if the condition is a complication of a procedure which may require different coding sequences.

Indicate the stage of the thrombus, such as acute versus chronic, as this affects treatment and coding.

Example: Right femoral vein thrombophlebitis is acute in nature, with no evidence of chronic post-thrombotic changes on imaging. Patient exhibits classic signs of acute inflammation including heat and tenderness along the right mid-thigh.

Billing Focus: Acute versus chronic status determines whether I80.211 or a post-thrombotic syndrome code (I87.0 series) is used.
