Unsp fx the lower end r rad, subs for clos fx w delay heal

This code signifies an unspecified fracture of the distal end of the right radius that is currently in a delayed healing phase. The fracture was initially treated as a closed injury, meaning there was no open wound communicating with the fracture site. The "subsequent encounter" indicates that this code is used for follow-up care after the initial treatment of the fracture.

Use this code when a patient presents for follow-up care of a right distal radius fracture that is not healing at the expected rate. This applies to situations where the fracture was initially closed and the specific type of fracture (e.g., Colles', Smith's) was not documented or is unknown. It is appropriate for office visits, physical therapy, or other encounters related to ongoing management of the delayed union.

• Ensure documentation clearly states "delayed healing" for a closed right distal radius fracture.
• Verify this is a subsequent encounter, not the initial treatment or an encounter for a malunion/nonunion.
• Always sequence this code after any applicable external cause codes if the cause of the fracture is being reported.
