    Typical Clinical Scenarios

    • A middle-aged construction worker presents to urgent care after tripping and scraping his right shin and anterior knee on rough concrete earlier the same day. He has superficial abrasions with minimal bleeding and no deep tissue involvement; wound cleaning, tetanus check, and dressing are provided. A superficial injury code for the right lower leg or knee in the initial encounter is assigned. Typical codes: S80.211A, S80.221A
    • An elderly nursing home resident with fragile skin develops noninfected superficial skin breakdown over the posterior left lower leg after prolonged immobility; staff request outpatient evaluation for dressing change and prevention of progression. Findings are limited to epidermal loss and excoriation without ulceration or deeper injury, so a superficial injury code for the left lower leg is used for follow-up care. Typical codes: S80.212D, S80.222D
    • A young athlete follows up in sports medicine clinic two weeks after a bicycle accident that caused multiple superficial lacerations and abrasions to the anterior bilateral knees; wounds are healing but require suture removal and scar management. Because this visit is for subsequent care of healing superficial injuries, a subsequent encounter superficial injury code for the knees/lower legs is assigned. Typical codes: S80.00XD, S80.10XD
