Path fx, unsp ulna and radius, subs for fx w delay heal

This code signifies a fracture of both the ulna and radius that occurred due to an underlying disease process, rather than trauma. The patient is in a subsequent phase of care, and the fracture is experiencing delayed healing, meaning it is taking longer than expected to unite.

Apply this code when documentation clearly indicates a pathological fracture involving both the ulna and radius, and the patient is being seen for ongoing management of the fracture. The "G" seventh character specifies a subsequent encounter where delayed healing is noted. Supporting documentation would include physician notes detailing the pathological nature of the fracture and the current status of delayed union.

• Ensure the documentation explicitly states "pathological fracture" and identifies both ulna and radius involvement.
• The seventh character "G" is crucial and indicates a subsequent encounter with delayed healing; do not use "A" (initial) or "K" (nonunion).
• Always code the underlying disease causing the pathological fracture first, followed by this code.
