Oth osteopor w crnt path fx, l femur, subs for fx w nonunion

This code signifies a patient presenting with osteoporosis, not otherwise specified as postmenopausal or drug-induced, who has sustained a pathological fracture of the left femur. The encounter is for follow-up care of this fracture, which has failed to heal properly (nonunion).

Apply this code for subsequent encounters where a patient with osteoporosis is being treated for a left femoral pathological fracture that has developed nonunion. Documentation should clearly state the presence of osteoporosis, the left femur as the fracture site, the pathological nature of the fracture, and the nonunion status during a follow-up visit.

• Ensure documentation specifies "pathological fracture" and "nonunion" for accurate code assignment.
• Distinguish from initial encounters (A) or subsequent encounters with routine healing (D) or delayed healing (P).
• Verify the laterality (left) and bone (femur) are explicitly documented.
