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

This code signifies a fracture of the left ulna that occurred due to a pre-existing disease process, rather than trauma. The patient is in the healing phase, and the fracture is progressing as expected without complications. This indicates ongoing management of a pathological fracture.

Apply this code when a patient presents for follow-up care of a left ulnar pathological fracture that is healing routinely. Documentation should clearly state "pathological fracture," specify the left ulna, and indicate a "subsequent encounter" with "routine healing." This code is appropriate for office visits, cast changes, or imaging reviews during the normal healing period.

• Ensure documentation explicitly states "pathological fracture" to differentiate from traumatic fractures.
• Verify laterality (left ulna) is clearly documented.
• Confirm the encounter type is "subsequent" and healing is "routine" to select the correct seventh character.
