Unsp fracture of shaft of humerus, unsp arm, init for opn fx

This code describes an open fracture of the shaft (the long, central part) of the humerus, the bone in the upper arm. The specific location of the fracture on the shaft and which arm is affected are not documented. This code is used for the initial treatment of the injury.

Use this code when documentation confirms an open fracture of the humeral shaft, but the laterality (left or right arm) and the precise location within the shaft (e.g., proximal, middle, distal) are not specified. This code is appropriate for the first encounter for treatment of this open fracture.

• Always seek clarification from the provider if the laterality or specific shaft location is missing.
• An "open fracture" implies a break in the skin over the fracture site.
• Ensure the "initial encounter" seventh character is appropriate for the patient's current stage of treatment.
