    Typical Clinical Scenarios

    • An elderly patient presents to the emergency department after a fall with hip pain; history reveals they previously had a total hip replacement on the affected side several years ago, and the current visit requires imaging and evaluation for periprosthetic fracture or dislocation. A code from this group is assigned to document the personal history of joint replacement to inform imaging interpretation and operative planning. Typical codes: Z92.3
    • A middle-aged adult scheduled for elective abdominal surgery reports a remote history of a splenectomy following trauma in childhood and is evaluated preoperatively for vaccination status and perioperative infection risk. A code from this group is assigned to record the prior surgical removal of the spleen that affects current perioperative management. Typical codes: Z92.22
    • A young woman with a history of prior therapeutic radiation for cervical cancer presents for routine follow-up; she has chronic pelvic radiation changes and fertility counseling is requested. A code from this group is assigned to capture the personal history of radiation therapy which influences surveillance and future reproductive planning. Typical codes: Z92.21, Z92.23
