Z89.41 Acquired absence of great toe

Name of the Condition

• Acquired absence of great toe

Summary

This condition refers to the loss or surgical removal of the great toe (hallux). It is categorized under ICD-10 code Z89.41 and is considered an acquired absence, often due to injury, disease, or surgical intervention.

Causes

Common causes include severe trauma or injury to the great toe, surgical removal due to complications from infections such as diabetic ulcers, or poor circulation leading to necrosis.

Risk Factors

• Individuals with diabetes, peripheral artery disease, or those who have experienced severe foot injuries are at higher risk.

Symptoms

• Absence of the great toe, affecting balance and walking. Possible associated pain or sensitivity in the remaining portion of the foot.

Diagnosis

Diagnosed through physical examination and patient history. Imaging may be used to assess the extent of related complications or to plan further treatment.

Treatment Options

• Treatments focus on rehabilitation and adaptation, including physical therapy and the use of custom orthotics or prosthetics to improve mobility and balance.

Prognosis and Follow-Up

Prognosis generally depends on the cause of the condition and overall health of the patient. Regular follow-up is important to monitor for complications and adjust treatment as needed.

Complications

• Potential complications include infection, delayed healing, phantom limb pain, or difficulty with mobility and balance.

Lifestyle & Prevention

• Maintaining good foot hygiene, managing underlying conditions like diabetes, and avoiding high-risk activities can help reduce the risk of complications.

When to Seek Professional Help

• Seek medical attention if there is severe pain, signs of infection (e.g., redness, swelling, fever), or difficulty with mobility after the loss of the great toe.

Tips for Medical Coders

• Use code Z89.41 for acquired absence of the great toe. Ensure documentation supports the acquired nature of the absence (e.g., surgical notes, trauma history) and specify the toe involved. Avoid using this code for congenital absence or other unrelated conditions.
