Nondisp commnt fx shaft of rad, unsp arm, 7thN

This code signifies a complex, non-healing fracture of the forearm, specifically involving the shaft of the radius bone. The fracture is comminuted (broken into multiple pieces) and nondisplaced, meaning the bone fragments are still in their anatomical alignment. This particular encounter is for an open fracture (skin broken) of a severe type (IIIA, IIIB, or IIIC) that has failed to heal properly (nonunion).

Use this code for a patient presenting for follow-up care, such as cast changes, wound care, or surgical planning, for a previously diagnosed open comminuted radial shaft fracture that has not united. This applies when the initial injury was a severe open fracture and the current assessment confirms nonunion. It is appropriate for ongoing management of this specific complication.

• Confirm documentation specifies "nondisplaced," "comminuted," and "shaft of radius."
• Ensure the encounter is for "nonunion" of an "open fracture type IIIA, IIIB, or IIIC."
• This code requires an additional code for the specific type of open fracture (e.g., S52.356B for initial encounter).
