Type 1 fracture of sacrum, subs for fx w nonunion

This code signifies a non-healing fracture of the first sacral segment, specifically a Type 1 fracture, which involves the ala of the sacrum. The patient is in a later stage of treatment, beyond the initial healing phase, and the fracture has failed to unite.

Apply this code when documenting follow-up care for a patient with a previously diagnosed Type 1 sacral ala fracture that has not healed as expected. This includes scenarios where surgical intervention for nonunion is being considered or performed, or during ongoing conservative management for a persistent nonunion.

• Ensure documentation clearly specifies "Type 1" sacral fracture and "nonunion" for accurate code assignment.
• This code is for subsequent encounters; do not use for the initial treatment of the fracture.
• Always code the underlying cause of the fracture if known and relevant to the encounter.
