S45.012D Laceration of axillary artery, left side, subsequent encounter

Name of the Condition

• Laceration of axillary artery, left side, subsequent encounter

Summary

This condition involves a tear or cut in the left axillary artery, a major blood vessel in the left armpit region. The laceration may disrupt blood flow to the left upper limb and requires ongoing medical attention to monitor for complications during recovery.

Causes

Common causes include penetrating trauma, such as stab wounds or gunshot injuries, and blunt trauma from fractures or dislocations of the shoulder or upper arm. Surgical procedures in the area may also result in accidental laceration.

Risk Factors

• Engaging in high-risk activities with potential for trauma, such as contact sports or motor vehicle accidents. Pre-existing vascular conditions or anatomical variations may increase susceptibility.

Symptoms

• Symptoms may include severe pain, swelling, bruising, or a visible wound in the left armpit. Reduced or absent pulse in the left arm, coldness, paleness, or weakness of the hand or arm may indicate compromised blood flow.

Diagnosis

Diagnosis typically involves a physical examination to assess pulse, sensation, and movement. Imaging tests like Doppler ultrasound, CT angiography, or MR angiography may be used to evaluate the artery and detect damage.

Treatment Options

• Treatment may include surgical repair to restore blood flow, use of anticoagulants or antiplatelet medications to prevent clots, and monitoring for complications.

Prognosis and Follow-Up

Prognosis depends on the extent of the injury and timely treatment. Follow-up care is essential to assess healing, monitor for complications, and ensure proper recovery of limb function.

Complications

• Potential complications include excessive bleeding, infection, nerve damage, or permanent loss of limb function if blood flow is not restored promptly.

Lifestyle & Prevention

• Avoid activities that increase risk of trauma to the armpit area. Use protective gear during high-risk activities and follow safety guidelines to minimize injury risk.

When to Seek Professional Help

Seek immediate medical attention if symptoms such as severe pain, swelling, or loss of pulse in the arm occur, as these may indicate a serious vascular injury.

Tips for Medical Coders

This code is used for a subsequent encounter for a laceration of the left axillary artery. Documentation should specify the laterality (left side) and the encounter type (subsequent) to support accurate coding.
