Unsp fx upper end unsp radius, subs for clos fx w nonunion

This code signifies a fracture of the upper portion of the radius bone, where the specific location (e.g., radial head, neck) is not documented. It indicates that the patient is in a later stage of treatment for a closed fracture that has failed to heal properly (nonunion).

Use this code for follow-up encounters when a patient presents with a previously diagnosed, unspecified closed fracture of the proximal radius that has not united. This applies when the physician is actively managing the nonunion, such as evaluating for surgical intervention or monitoring conservative treatment.

• Requires a seventh character of "K" for subsequent encounter with nonunion.
• Ensure documentation clearly states "nonunion" and that the fracture is closed.
• Do not use for initial encounters or for fractures that are healing normally.
