Nondisp fx of nk of unsp rad, 7thN

This code describes a situation where a patient has a fracture in the neck of an unspecified radius bone that was initially nondisplaced. The current encounter is for ongoing management of this fracture, which is complicated by a severe open wound (Type IIIA, IIIB, or IIIC) and has failed to heal properly (nonunion).

Use this code for follow-up encounters where a patient is being treated for a previously diagnosed nondisplaced radial neck fracture. The key indicators for this specific code are the presence of a severe open fracture type (IIIA, IIIB, or IIIC) and the documentation of nonunion, meaning the bone fragments have not united after a reasonable healing period.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" status.
• Verify the open fracture type (IIIA, IIIB, or IIIC) is explicitly stated in the medical record.
• This code is for an unspecified radius; if laterality is known, a more specific code should be used.
