S45.001S Unspecified injury of axillary artery, right side, sequela

Name of the Condition

• Unspecified injury of axillary artery, right side, sequela

Summary

This condition represents the residual effects of a prior unspecified injury to the axillary artery on the right side. It reflects ongoing consequences of the initial trauma, which may involve persistent vascular damage or related complications affecting the right upper limb.

Causes

The sequela arises from a previous unspecified injury to the axillary artery on the right side. Common initial causes of such injuries include penetrating or blunt trauma (e.g., stab wounds, gunshot injuries, fractures, or shoulder dislocations) or iatrogenic damage during surgical procedures in the area.

Risk Factors

• History of trauma to the right shoulder or upper arm region. Pre-existing vascular conditions or anatomical variations may have contributed to the initial injury and subsequent sequelae.

Symptoms

• Persistent symptoms may include chronic pain, swelling, or discoloration in the right armpit. Reduced or absent pulse, coldness, paleness, or weakness in the right hand or arm may indicate ongoing compromised blood flow. Functional limitations or sensory changes in the limb may also occur.

Diagnosis

Diagnosis involves reviewing the patient’s prior injury history and assessing current symptoms. Physical examination evaluates pulse, sensation, and movement in the right upper limb. Imaging tests (e.g., Doppler ultrasound, CT angiography, or MR angiography) may be used to assess residual arterial damage or complications.

Treatment Options

• Management focuses on addressing residual symptoms and preventing further complications. This may include monitoring for vascular issues, pain management, physical therapy to improve function, or surgical intervention if structural damage persists.

Prognosis and Follow-Up

Prognosis depends on the severity of the initial injury and the extent of residual damage. Regular follow-up is important to monitor for complications such as chronic ischemia, aneurysm formation, or nerve injury. Long-term care may involve periodic imaging or functional assessments.

Complications

• Potential complications include chronic limb ischemia, pseudoaneurysm, arteriovenous fistula, or nerve damage affecting the right upper limb. In severe cases, amputation may be necessary if blood flow cannot be restored.

Lifestyle & Prevention

• Avoid activities that risk re-injury to the right shoulder or arm. Maintain regular follow-up with healthcare providers to monitor vascular health. Smoking cessation and management of vascular risk factors (e.g., hypertension, diabetes) may support healing.

When to Seek Professional Help

Seek immediate medical attention if symptoms worsen (e.g., increased pain, sudden limb discoloration, or loss of pulse) or if new neurological symptoms (e.g., numbness, weakness) develop. Routine follow-up is recommended to address persistent or new concerns.

Tips for Medical Coders

This code is used for the sequela of an unspecified injury to the axillary artery on the right side. Document the nature of the residual effects (e.g., chronic pain, vascular insufficiency) and confirm the prior injury history. Ensure the code aligns with the patient’s current clinical status and that no more specific sequela code applies.
