Nondisp fx of neck of unsp rad, subs for clos fx w nonunion

This code describes a situation where a patient has a fracture in the neck of the radius bone, but the bone fragments are still in their normal anatomical position (nondisplaced). Crucially, this is a follow-up encounter where the fracture has failed to heal properly (nonunion) and is being managed without surgical intervention (closed fracture).

Use this code for patients presenting for ongoing management of a previously diagnosed nondisplaced radial neck fracture that has not united. This applies to follow-up visits, imaging reviews, or conservative treatment for the nonunion, provided the fracture was initially closed.

• Ensure documentation clearly states "nonunion" and that the fracture is "nondisplaced" and "closed."
• Verify this is a subsequent encounter, not the initial treatment for the fracture.
• Confirm the specific bone involved is the radius and the location is the neck.
