    ICD-10-CM Code For Injury Of Blood Vessels At Shoulder And Upper Arm Level: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group S45 includes traumatic injuries to arteries and veins at the shoulder and upper arm level, such as lacerations, punctures, and crush injuries affecting major vascular structures. These ICD-10-CM diagnosis codes are used to document acute vascular compromise, need for repair or reconstruction, and the presence of associated soft tissue or bone injury that affects clinical complexity. Accurate coding within the ICD-10-CM S45 group supports proper claim adjudication and complete clinical documentation and appropriate reimbursement.

    This group represents traumatic injuries to the arteries and veins located at the shoulder and upper arm level, including lacerations, punctures, and crushing injuries. It targets the vascular structures of the upper extremity and is part of injuries to the shoulder and upper arm. Accurate coding matters for appropriate clinical documentation and reimbursement because vascular injuries can affect surgical decisions, length of stay, and resource use.

    Typical Clinical Scenarios

    • A construction worker presents to the emergency department after a high-energy fall onto the outstretched arm with swollen, expanding hematoma and active bleeding at the lateral shoulder. On exam there is pulsatile bleeding and absent distal pulses, and angiography confirms laceration of an unnamed vessel at the shoulder level requiring immediate surgical repair; an initial encounter code from the group is assigned for the acute vascular injury. Typical codes: S45.001A, S45.009A
    • An elderly patient on anticoagulation is evaluated in clinic days after a minor shoulder contusion for increasing pain, bruising, and a progressive non-pulsatile hematoma causing nerve compression and limited shoulder motion. The delayed presentation without active external hemorrhage is documented as a subsequent encounter for the vascular injury while anticoagulation contributed to the hematoma expansion. Typical codes: S45.001D, S45.091D
    • A patient seen during a rehabilitation admission after shoulder fracture fixation develops ischemic hand changes and is diagnosed with chronic occlusion of a shoulder-level vessel related to prior traumatic injury; care is focused on monitoring and long-term sequelae rather than acute repair. A sequela code from the group is assigned to indicate the late effects of the original vascular injury. Typical codes: S45.001S, S45.091S
