S90.412 Abrasion, left great toe

Name of the Condition

• Abrasion, left great toe (ICD-10 code: S90.412)

Summary

An abrasion of the left great toe is a superficial injury where the top layer of skin is scraped or worn away, typically due to friction or minor trauma. This condition affects the largest toe on the left foot and may involve varying degrees of skin damage, depending on the force and duration of the contact.

Causes

Direct contact with rough surfaces, such as walking barefoot on gravel or concrete. Friction from ill-fitting shoes or socks. Minor impacts, like stubbing the toe against an object.

Risk Factors

• Wearing tight or poorly constructed footwear.
• Engaging in activities that increase toe exposure to friction or trauma (e.g., hiking, sports).
• Reduced sensation in the feet, which may delay awareness of injury.

Symptoms

• Redness and raw skin on the affected toe.
• Mild bleeding or clear fluid discharge.
• Pain, burning, or stinging sensation at the site.

Diagnosis

Physical examination of the toe to assess the extent of skin damage. Review of the patient's history to identify potential causes, such as recent activities or footwear changes.

Treatment Options

• Cleaning the area with mild soap and water to prevent infection.
• Applying antiseptic and protective bandages to promote healing.
• Over-the-counter pain relief medications if discomfort is significant.

Prognosis and Follow-Up

Most abrasions heal within a week with proper care. Follow-up may be recommended if symptoms worsen or fail to improve, indicating possible infection or deeper injury.

Complications

• Infection, particularly if the wound is not cleaned properly.
• Delayed healing due to underlying conditions like diabetes.
• Scarring, though rare for superficial abrasions.

Lifestyle & Prevention

• Wear properly fitting, supportive footwear to reduce friction.
• Use protective gear during activities that risk toe injury.
• Inspect feet regularly, especially for those with reduced sensation.

When to Seek Professional Help

Seek care if the abrasion shows signs of infection (e.g., increased redness, pus, fever), fails to heal, or causes severe pain.

Tips for Medical Coders

Document the specific location (left great toe) and nature of the injury (abrasion) to support accurate coding. Include details on the encounter type (e.g., initial, subsequent) if applicable. Ensure clinical documentation aligns with the code's specificity.
