Pathological fracture, right ulna, subs for fx w routn heal

This code signifies a bone fracture in the right ulna that occurred due to a pre-existing disease weakening the bone, rather than trauma. The patient is currently in a phase of recovery where the fracture is healing as expected without complications.

Apply this code for follow-up encounters where a patient is receiving ongoing care for a pathological fracture of the right ulna, and the physician's documentation indicates routine healing. This code is appropriate when the initial treatment has been rendered and the patient is progressing through the healing process without setbacks.

• Ensure documentation specifies "pathological fracture" and "right ulna" to support code selection.
• The "D" seventh character indicates a subsequent encounter for routine healing; use "A" for initial encounters or "S" for sequelae.
• Always code the underlying disease causing the pathological fracture (e.g., osteoporosis, neoplasm) first, followed by this fracture code.
