ICD-10-PCS Codes

ICD-10-PCS Code	Description
2W3AX1Z	Immobilization of Right Upper Arm using Splint
2W3AX2Z	Immobilization of Right Upper Arm using Cast
2W3AX3Z	Immobilization of Right Upper Arm using Brace
2W3AXYZ	Immobilization of Right Upper Arm using Other Device

Typical Clinical Scenarios

A middle-aged patient arrives to the emergency department after a fall onto an outstretched hand, sustaining a displaced midshaft humeral fracture of the right arm with significant pain and deformity. After closed reduction in the ED or operating room, an immobilization device is applied to limit motion of the right upper arm to maintain fracture alignment and facilitate inpatient pain control and monitoring prior to definitive orthopedic management. The procedure documents placement of a splint on the right upper arm to stabilize the fracture and control swelling. Typical codes: 2W3AX1Z
An adult admitted for postoperative care following open reduction and internal fixation of a right proximal humerus fracture requires ongoing immobilization to protect the surgical repair during the immediate recovery period. As part of inpatient postoperative orders, a molded brace is applied to the right upper arm to restrict movement while the patient is monitored for neurovascular status and wound healing. The brace placement is documented as the method used for immobilization to support the fixation. Typical codes: 2W3AX3Z
An elderly patient with a healing right humeral shaft fracture presents with cast breakdown and increasing pain and skin irritation after several days in a temporary cast applied at an outside facility. Inpatient management includes removing the compromised cast and applying a new circumferential cast to ensure proper immobilization, protect the skin, and prevent loss of fracture alignment while addressing the complication. The procedure specifically involves placement of a cast on the right upper arm as the corrective immobilization measure. Typical codes: 2W3AX2Z
