Unsp fracture of right foot, subs for fx w nonunion

This code signifies an unconfirmed or unspecified fracture location within the right foot that has failed to heal properly after an initial treatment. The patient is presenting for follow-up care related to this persistent nonunion.

Apply this code when documentation indicates a patient is being seen for ongoing management of a right foot fracture where the specific bone involved is not identified, and the fracture has not united. This is appropriate for subsequent visits after the initial treatment for the nonunion has begun.

• Ensure documentation clearly states "nonunion" and specifies the right foot.
• Verify that the encounter is for subsequent care, not the initial treatment of the nonunion.
• If the specific bone of the foot is identified, a more precise code from S92.0-S92.8 should be used instead.
