Displaced comminuted fx shaft of radius, unsp arm, init

This code signifies a severe break in the main part of the radius bone, where the bone has shattered into multiple pieces and the fragments are no longer in their normal alignment. The injury is located in an unspecified arm, meaning the documentation does not specify whether it's the left or right radius.

Apply this code for initial treatment of a closed comminuted radial shaft fracture where the displacement is explicitly documented, but the laterality (left/right) is not specified. This is typically seen in emergency department visits or initial orthopedic consultations following an acute injury.

• Ensure documentation clearly states "comminuted" and "displaced" for the radial shaft.
• Only use the "A" seventh character for the initial encounter for active treatment of the fracture.
• If laterality (left or right) is specified in the medical record, a more specific code should be used.
