Nondisp transverse fx shaft of unsp rad, 7thM

This code describes a situation where a patient has a non-displaced break across the shaft of an unspecified radius bone that is failing to heal (nonunion). This particular encounter is for ongoing treatment of an open fracture, specifically Gustilo type I or II, which occurred previously.

Use this code for follow-up encounters when a patient with a previously diagnosed open transverse shaft fracture of the radius (Gustilo type I or II) is experiencing nonunion. This applies when the fracture fragments are still in their anatomical position. This code would be appropriate for subsequent visits involving cast changes, physical therapy, or surgical planning for the nonunion.

• Requires a seventh character "M" for subsequent encounter with nonunion.
• Confirm the fracture is specifically of the radial shaft and is transverse and nondisplaced.
• Ensure documentation specifies the original injury was an open fracture type I or II.
