S90.413 Abrasion, unspecified great toe

Name of the Condition

• Abrasion, unspecified great toe (ICD-10 code: S90.413)

Summary

An abrasion of the unspecified 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 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 signs of infection develop, such as increased redness, swelling, or pus.

Complications

Infection, delayed healing, or scarring if the injury is not properly cleaned or cared for.

Lifestyle & Prevention

• Wear properly fitting shoes and socks to reduce friction.
• Use protective footwear in environments with rough surfaces.
• Inspect feet regularly, especially for those with reduced sensation.

When to Seek Professional Help

Seek care if the abrasion shows signs of infection, does not heal within two weeks, or is deep and bleeding heavily.

Tips for Medical Coders

Document the location (unspecified great toe) and any contributing factors, such as trauma or footwear, to support code assignment. Ensure the abrasion is not associated with more severe injuries that would require a different code.
