§
In ICD-10 the forearm codes include those of the distal forearm, which are those termed as “wrist fractures” in clinical practice and in the fracture risk calculators Frax and QFracture. In ICD-10 the wrist fracture codes relate to the carpal bones (S62.0 scaphoid, S62.1 other and unspecified), which on their own are not termed wrist fractures in clinical practice or included in the fracture risk calculators.
