S90.8: Other superficial injuries of ankle and foot

The ICD-10 code S90.8 refers to other superficial injuries of the ankle and foot. Superficial injuries are those that affect the skin or tissue directly beneath the skin. That said, this particular category encompasses a vast array of mild injuries to the ankle or foot that do not cause significant damage to deeper structures like bones, ligaments, or tendons. These injuries can include simple bruises, minor burns, scrapes, or cuts. Commonly, such injuries occur during regular daily activities such as walking or running, sports, an accidental bump or knock against a hard surface, or due to occupational hazards for people engaged in physically demanding work. Symptoms can range from mild pain or swelling, to skin redness and warmth over the affected site. Despite the relative mildness of these injuries, complications may arise if not properly taken care of, such as infection or delayed healing, especially in individuals with compromised immune systems or poor circulation.
