Answer: B
S52.372 is the appropriate code for this case as it codes for Galeazzi’s fracture of the left radius, which is the diagnosis here.
Option A is not correct because S52.371 codes for Galeazzi’s fracture of the right radius, but here, the fracture is in the left radius.
Option C is not correct because it codes for Galeazzi’s fracture of an unspecified radius. Since the radius is mentioned in the question; this code is not appropriate.
Option D is not correct because S52.352 codes for displaced comminuted fractures in the shaft of the radius of the left arm. Here, a comminuted fracture is not seen.
