S45.011D Laceration of axillary artery, right side, subsequent encounter

Name of the Condition

• Laceration of axillary artery, right side, subsequent encounter

Summary

This condition involves a tear or cut in the right axillary artery, a major blood vessel in the armpit region, during a subsequent encounter for care. The laceration may disrupt blood flow to the upper limb and requires ongoing medical attention to manage complications and monitor 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. The subsequent encounter indicates ongoing care following the initial injury.

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 armpit. Reduced or absent pulse in the 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. The subsequent encounter context implies ongoing assessment of healing or complications.

Treatment Options

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

Prognosis and Follow-Up

Prognosis depends on the extent of the injury and timeliness of treatment. Follow-up care is essential to monitor for complications, such as infection or re-laceration, and to assess recovery of blood flow and limb function.

Complications

• Potential complications include excessive bleeding, infection, thrombosis, or permanent damage to the artery or surrounding tissues. Nerve injury or limb ischemia may also occur.

Lifestyle & Prevention

• Avoid activities that increase risk of trauma to the armpit region. Use protective gear during high-risk activities, and follow post-treatment guidelines to support healing.

When to Seek Professional Help

Seek immediate medical attention if symptoms worsen, such as increased pain, swelling, or signs of reduced blood flow (e.g., coldness, paleness). Follow up with a healthcare provider as scheduled for ongoing care.

Tips for Medical Coders

Document the laterality (right side) and the nature of the encounter (subsequent) to ensure accurate coding. Include details of the injury, treatment provided, and any complications to support the code assignment.
