Nondisp spiral fx shaft of ulna, r arm, 7thM

This code signifies a right ulna fracture that follows a spiral pattern along the bone's shaft, without displacement of the bone fragments. It specifically indicates that the initial injury was an open fracture (Type I or II), and the bone has failed to heal properly, resulting in a nonunion. This is a subsequent encounter, meaning the patient is receiving ongoing care for this unhealed fracture.

Use this code for follow-up encounters where a patient with a previously diagnosed right ulna spiral shaft fracture, initially open (Type I or II), is presenting with evidence of nonunion. This would apply during clinic visits for monitoring, cast changes, or discussions regarding further surgical intervention for the nonunion.

• Ensure documentation clearly specifies "right arm" and "ulna shaft" to differentiate from other forearm bones or locations.
• Verify the original injury was an "open fracture type I or II" and that "nonunion" is explicitly documented.
• Confirm this is a "subsequent encounter" and not the initial treatment for the fracture.
