ICD-10-CM S90: Superficial Injury Of Ankle, Foot And Toes Overview

The diagnoses in this group represent superficial traumatic injuries affecting the skin and soft tissues of the ankle, foot, and toes, such as abrasions, contusions, and superficial lacerations. These codes target injuries to the lower extremity integumentary structures and are used to classify the location and type of superficial trauma. Accurate coding matters for correct claim processing and to reflect the clinical detail needed for appropriate reimbursement and quality reporting.

When to Use

Use a code from this group when the clinical record documents a superficial injury to the ankle, foot, or toes without deeper tissue involvement such as fracture, tendon, or joint injury. Select the code that specifies the injury type and laterality or specific toe when documented to reflect the encounter accurately.

Typical Clinical Scenarios

An adult presents to the emergency department after slipping on a wet floor and sustaining a superficial laceration and skin avulsion to the dorsum of the right foot with minimal bleeding. The wound is cleaned, debrided, and dressed; there is no tendon or fracture involvement and the injury is an initial encounter for treatment, so a superficial injury code for the right foot is assigned. Typical codes: S90.111A, S90.112A
An elderly patient in a nursing home develops a nonpurulent superficial pressure-related abrasion over the medial ankle after prolonged immobility; the wound is being followed in the clinic for wound care and is a subsequent encounter for routine dressing changes and assessment. Because this is follow-up care for a healing superficial injury of the ankle, a subsequent encounter superficial injury code for the ankle is used. Typical codes: S90.219D, S90.229D
A young athlete is seen at an urgent care three weeks after sustaining a crush injury to the toes during a sports event; the area has persistent superficial skin breakdown with scab formation and complaints of localized pain but no deep infection, and care is for sequelae/management of the healing superficial injury. A sequela or healing-specific code from the group is selected to reflect ongoing care for the toe injuries. Typical codes: S90.00XS, S90.01XS
