Fx unsp parts of lumbosacr spin & pelv, 7thK

This code signifies a fracture affecting an unknown or unspecified area of the lower back (lumbar spine), sacrum, or pelvis that has failed to heal properly. The patient is in a later stage of treatment, and the bone fragments have not united after a reasonable healing period.

This code is appropriate for follow-up encounters where a previously diagnosed lumbosacral or pelvic fracture, whose exact location was not specified, is now documented as having nonunion. This would typically be used when the patient is undergoing continued management for the unhealed fracture, such as consideration for surgical intervention or further conservative treatment.

• Ensure documentation clearly states "nonunion" for an unspecified lumbosacral or pelvic fracture.
• Verify that this is a subsequent encounter, not the initial treatment for the fracture.
• Avoid using this code if a more specific anatomical site of the fracture is known and documented.
