S90.819 Abrasion, unspecified foot

Name of the Condition

• Abrasion, unspecified foot

Summary

An abrasion of the unspecified foot is a superficial injury to the skin caused by friction or scraping, resulting in the removal of the outermost layer of skin. This type of injury typically presents as a raw, irritated area and may be accompanied by minor bleeding or discomfort. Abrasions are common in areas exposed to friction or trauma and generally heal without significant complications.

Causes

Abrasions of the unspecified foot often result from direct contact with rough surfaces, such as pavement, gravel, or textured materials, during activities like walking, running, or falling. Friction from ill-fitting footwear or repetitive rubbing can also lead to this type of injury. Minor trauma, such as stubbing the foot or scraping against objects, may contribute to the development of an abrasion.

Risk Factors

• Participation in activities with high risk of foot trauma, such as hiking, sports, or manual labor.
• Wearing poorly fitting or worn-out shoes that increase friction.
• Environments with rough or uneven surfaces, increasing the likelihood of scraping.
• Pre-existing skin conditions or reduced sensation in the feet, which may impair awareness of injury.

Symptoms

• Pain or tenderness at the site of the abrasion.
• Redness, swelling, or minor bleeding.
• A raw or grazed appearance of the skin.
• Possible crusting or scabbing as healing progresses.

Diagnosis

Diagnosis is typically based on a physical examination of the affected area. Healthcare providers assess the appearance of the skin, including redness, rawness, or minor bleeding, to confirm the abrasion. No specialized tests are usually required unless there is suspicion of deeper tissue damage or infection.

Treatment Options

Treatment generally involves cleaning the area with mild soap and water to remove debris, followed by applying an antibiotic ointment and covering with a sterile bandage to protect against infection. Over-the-counter pain relievers may be used for discomfort. Keeping the area clean and dry promotes healing.

Prognosis and Follow-Up

Most abrasions heal within 1–2 weeks with proper care. Follow-up is usually unnecessary unless signs of infection, such as increased redness, pus, or fever, develop. Severe or persistent symptoms may require medical reevaluation.

Complications

Complications are rare but may include infection, especially if the wound is not properly cleaned or covered. Delayed healing can occur in individuals with poor circulation or weakened immune systems.

Lifestyle & Prevention

• Wear properly fitting, protective footwear during activities with a high risk of foot trauma.
• Avoid walking barefoot in environments with rough or abrasive surfaces.
• Use padding or protective gear in high-friction areas, such as during sports or manual labor.
• Maintain good foot hygiene to support skin integrity.

When to Seek Professional Help

Seek medical attention if the abrasion shows signs of infection (e.g., increased pain, swelling, pus, or red streaks), does not heal within two weeks, or is deep enough to expose underlying tissue. Individuals with diabetes or poor circulation should consult a healthcare provider promptly.

Tips for Medical Coders

Document the location as "unspecified foot" when the specific foot (right or left) is not identified in the clinical record. Ensure the abrasion is clearly described as a superficial skin injury without deeper tissue involvement to align with the code's definition.
