In simple words: This code is used when a bone in your hip breaks because it's been weakened by a tumor, and it hasn't healed properly after a previous visit.

This code describes a non-traumatic fracture of the pelvis due to a weakened bone structure caused by a tumor (benign or cancerous).It is used for subsequent encounters where the fracture has failed to heal (nonunion).

Example 1: A patient with a history of bone cancer in the pelvis presents with persistent pain and limited mobility months after initial treatment for a pathological fracture. Imaging confirms nonunion of the fracture., A patient undergoing chemotherapy for a pelvic tumor experiences a sudden onset of hip pain after a minor fall. Imaging reveals a pathological fracture. This is the second visit regarding this fracture and nonunion is present., A patient with a benign pelvic tumor experiences a fracture while walking.Following initial treatment, they return for a follow-up appointment where nonunion of the fracture is diagnosed.

Documentation should include evidence of the underlying neoplasm, the pathological fracture, details of the nonunion (e.g., imaging reports), and all treatment provided.
