I82.A19 Acute embolism and thrombosis of unspecified axillary vein

Name of the Condition

• Acute Embolism and Thrombosis of Unspecified Axillary Vein

Summary

Acute embolism and thrombosis of the unspecified axillary vein refers to the sudden formation or lodgment of a blood clot in the axillary vein, which can obstruct blood flow from the arm and shoulder. This condition may lead to localized symptoms and potential complications if not addressed promptly.

Causes

The condition may result from factors that promote blood clotting, such as injury to the vein wall, prolonged immobility, or underlying disorders that increase clotting propensity. Surgical procedures, trauma, or inflammation of the vein can also contribute to clot formation.

Risk Factors

• Prolonged immobility or bed rest
• Recent surgery or trauma to the arm/shoulder
• Cancer or cancer treatments
• Obesity
• Smoking
• Pregnancy and postpartum period
• Family history of thrombosis
• Use of hormonal contraceptives or hormone replacement therapy

Symptoms

• Swelling in the affected arm or shoulder
• Pain or tenderness in the axillary region
• Redness or warmth over the clot site
• Visible enlarged veins
• Possible skin discoloration or ulceration in chronic cases

Diagnosis

Diagnosis typically involves imaging studies like ultrasound, CT, or MRI to visualize the clot, along with blood tests (e.g., D-dimer) to assess clotting activity. Clinical evaluation of symptoms and risk factors is also essential for confirmation.

Treatment Options

Treatment may include anticoagulant medications to prevent clot growth, thrombolytic therapy for severe cases, and compression garments to reduce swelling. In some instances, surgical intervention may be necessary to remove the clot or place a filter.

Prognosis and Follow-Up

With prompt treatment, prognosis is generally favorable, though complications like post-thrombotic syndrome or pulmonary embolism may occur. Follow-up care often involves monitoring for recurrence and managing underlying risk factors.

Complications

• Post-thrombotic syndrome (chronic pain, swelling, or skin changes)
• Pulmonary embolism (if the clot travels to the lungs)
• Venous gangrene (rare, in severe cases)
• Recurrent thrombosis

Lifestyle & Prevention

• Stay active and avoid prolonged immobility
• Maintain a healthy weight
• Quit smoking
• Follow medical advice for managing underlying conditions (e.g., cancer, hormonal therapies)
• Use compression devices during long periods of sitting or lying down

When to Seek Professional Help

Seek immediate medical attention if you experience sudden swelling, pain, or discoloration in the arm or shoulder, as these may indicate a serious clot.

Tips for Medical Coders

Document the side (right/left) if specified, as this impacts code assignment. For unspecified cases, use I82.A19. Ensure clinical documentation supports the diagnosis and any associated risk factors or complications to justify code selection.
