Unsp fracture of left foot, subs for fx w nonunion

This code signifies an unspecified break in a bone of the left foot that has failed to heal properly. It indicates that the patient is presenting for ongoing care related to this non-healing fracture, rather than the initial injury or routine healing. The specific bone involved in the foot fracture is not documented.

Use this code when a patient is seen for follow-up care, management, or treatment of a left foot fracture that has been diagnosed with nonunion. This includes scenarios such as surgical intervention for nonunion, casting changes, or evaluation of pain and instability due to the unhealed fracture. It is appropriate when the exact location of the fracture within the foot is not specified in the medical record.

• Always ensure documentation clearly states "nonunion" and specifies the left foot.
• Verify that the encounter is for subsequent care, not the initial injury or routine healing.
• If the specific bone of the foot is known, a more precise code from the S92.9- series should be used.
