Oth osteopor w crnt path fx, unsp femr, 7thK

This code signifies a patient diagnosed with osteoporosis, experiencing a pathological fracture of an unspecified femur that is not healing properly (nonunion). The encounter is for ongoing management of this nonunion fracture, rather than the initial treatment.

This code is appropriate for subsequent encounters when a patient with osteoporosis presents for treatment of a femoral pathological fracture that has failed to unite. Documentation should clearly indicate osteoporosis as the underlying cause of the fracture, the nonunion status, and that this is not the initial treatment episode.

• Ensure documentation specifies "pathological fracture" due to osteoporosis, not a traumatic fracture.
• Verify the encounter is "subsequent" and not initial care; otherwise, a different 7th character would be used.
• Always code the underlying osteoporosis (M81.-) first, followed by the pathological fracture code.
