Bent bone of unsp radius, subs for clos fx w nonunion

This code describes a closed fracture of the radius, specifically a bent bone type, that has failed to heal properly and is being treated in a subsequent encounter. "Bent bone" refers to a specific type of fracture where the bone is significantly angled or curved but not completely broken into separate pieces. "Nonunion" indicates that the bone ends have not united after a reasonable healing period.

This code is appropriate for follow-up visits where a patient is receiving ongoing management for a previously diagnosed closed bent bone fracture of the radius that has not healed. This includes scenarios such as monitoring the nonunion, considering further interventions like bone grafting, or preparing for surgical correction. It should be used when the initial treatment has failed to achieve bone union.

• Ensure documentation clearly specifies "nonunion" and that the fracture is closed.
• Verify that the encounter is subsequent to the initial treatment of the fracture.
• Do not use for malunion, which implies healing in an incorrect position, but rather for a complete failure to heal.
