S91.101S Unspecified open wound of right great toe without damage to nail, sequela

Name of the Condition

• Unspecified open wound of right great toe without damage to nail, sequela

Summary

This condition describes a sequela (late effect) of an open wound to the right great toe where the nail remains undamaged. The wound involves a break in the skin or mucous membrane that has healed but may result in residual effects, such as scarring or functional impairment. Proper evaluation is necessary to assess the extent of residual damage and guide management.

Causes

Sequela of an open wound to the right great toe without nail damage typically results from prior trauma, such as cuts, abrasions, or blunt force injuries. Common causes include stepping on sharp objects, stubbing the toe, or minor accidents involving the toe. The sequela arises as a late effect of the initial injury.

Risk Factors

• Engaging in activities without protective footwear (e.g., walking barefoot or in open-toed shoes).
• Occupations involving manual labor or exposure to sharp materials.
• Participation in sports or outdoor activities with a high risk of toe injury.
• Delayed or inadequate initial wound care, which may increase the likelihood of residual effects.

Symptoms

• Persistent pain, swelling, or tenderness at the site of the healed wound.
• Visible scarring or changes in skin texture.
• Difficulty wearing shoes or bearing weight on the affected toe.
• Reduced range of motion or functional impairment in the toe.

Diagnosis

Diagnosis is based on a physical examination to assess residual effects, such as scarring, tissue damage, or functional limitations. A medical history is taken to evaluate the mechanism of the initial injury and any prior treatments. Imaging may be used to rule out underlying bone or tissue damage if indicated.

Treatment Options

• Monitoring for persistent symptoms or complications.
• Physical therapy to improve mobility or reduce pain.
• Topical or systemic treatments for scar management.
• Orthotic devices or footwear modifications to alleviate discomfort.

Prognosis and Follow-Up

Prognosis depends on the severity of the initial injury and the extent of residual effects. Most sequela improve with appropriate care, but some may persist long-term. Follow-up appointments are recommended to assess healing and adjust treatment as needed.

Complications

• Chronic pain or discomfort.
• Persistent scarring or tissue changes.
• Reduced mobility or functional impairment.
• Increased risk of future injury to the affected toe.

Lifestyle & Prevention

• Wear protective footwear during activities with a high risk of toe injury.
• Maintain good foot hygiene to prevent infections.
• Avoid repetitive trauma to the affected toe.
• Use padding or orthotics to reduce pressure on the area.

When to Seek Professional Help

Seek medical attention if residual symptoms worsen, new pain or swelling develops, or there are signs of infection (e.g., redness, pus, or fever). Prompt evaluation is important for managing complications or adjusting treatment.

Tips for Medical Coders

Document the sequela status and specify the right great toe without nail damage. Ensure the medical record supports the late effect of the initial wound and any residual symptoms or complications. Code S91.101S is used for sequela; verify that the injury is no longer in the acute phase.
