S91.102S Unspecified open wound of left great toe without damage to nail, sequela

Name of the Condition

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

Summary

This condition describes a sequela (late effect) of an open wound to the left 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. Evaluation is necessary to assess the extent of residual damage and guide management.

Causes

Sequela of an open wound to the left great toe without nail damage typically result 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 activities with a high risk of toe injury.
• Delayed or inadequate initial wound care, increasing the risk of complications.

Symptoms

• Visible scarring or altered tissue at the site of the prior wound.
• Persistent pain, stiffness, or reduced mobility in the left great toe.
• Changes in sensation (e.g., numbness or hypersensitivity) at the injury site.
• Difficulty wearing shoes or bearing weight due to residual tissue changes.

Diagnosis

Diagnosis is based on a physical examination to assess residual tissue damage, scarring, or functional impairment. A medical history is taken to confirm the prior open wound and evaluate the timeline of healing. Imaging may be used to rule out underlying bone or joint issues if symptoms persist.

Treatment Options

• Monitoring for resolution of residual symptoms without intervention.
• Physical therapy to improve mobility or reduce stiffness.
• Topical or systemic treatments for persistent pain or sensitivity.
• Surgical intervention (e.g., scar revision) if functional impairment or cosmetic concerns are significant.

Prognosis and Follow-Up

Prognosis depends on the severity of the initial injury and the extent of residual damage. Most sequela improve over time with conservative management, but some may require ongoing care. Follow-up is recommended to assess healing and address any persistent symptoms or complications.

Complications

• Chronic pain or discomfort at the injury site.
• Persistent scarring or tissue contracture affecting toe function.
• Increased risk of future injury to the affected area due to altered tissue integrity.
• Psychological impact from cosmetic changes or functional limitations.

Lifestyle & Prevention

• Wear protective footwear during activities with a high risk of toe injury.
• Maintain good foot hygiene to prevent infection in residual wounds.
• Avoid repetitive stress on the left great toe to reduce exacerbation of symptoms.
• Use orthotic devices or padding if scarring causes pressure or discomfort.

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 if functional impairment interferes with daily activities.

Tips for Medical Coders

This code (S91.102S) is used for the sequela of an unspecified open wound of the left great toe without nail damage. Document the prior injury, timeline of healing, and residual effects to support coding. Ensure the sequela is directly linked to the initial wound and that no active infection or acute injury is present.
