Oth osteopor w crnt path fx, l low leg, 7thK

This diagnosis code signifies a pathological fracture of the left lower leg (tibia, fibula, or ankle) that has occurred due to underlying osteoporosis, and is currently experiencing a nonunion. The patient is presenting for follow-up care related to this fracture.

Apply this code when documentation explicitly states a pathological fracture of the left lower leg, caused by osteoporosis, and indicates a nonunion of the fracture. This code is appropriate for subsequent encounters where the patient is receiving ongoing treatment or evaluation for the nonunion.

• Ensure documentation clearly specifies "nonunion" of the fracture, not just delayed healing.
• Always sequence this code after the underlying osteoporosis code (e.g., M81.0 for age-related osteoporosis).
• Verify the laterality (left) and anatomical site (lower leg) are precisely documented.
