Bent bone of unsp rad, subs for opn fx type I/2 w delay heal

This code describes a bent or malunion deformity of an unspecified part of the radius bone, specifically when the patient is in a subsequent phase of care for an open fracture (Type I or II) that is experiencing delayed healing. It indicates that the initial injury was an open fracture, and the current focus is on the ongoing management of the bone's abnormal alignment and slow healing process.

Use this code for follow-up encounters where a patient with a previously treated open radial fracture (Type I or II) presents with evidence of a bent or malaligned radius and the fracture union is progressing slower than expected. This applies when the patient is no longer in the initial acute phase of treatment but still requires ongoing care for the fracture and its complications.

• Ensure documentation clearly specifies "bent bone" or "malunion" of the radius and confirms delayed healing of an open fracture.
• Verify the encounter is for subsequent care, not the initial treatment of the fracture.
• Always code the specific type of open fracture (Type I or II) if known and applicable for the initial injury.
