Type 3 fracture of sacrum, subs for fx w nonunion

This code signifies a specific type of sacral fracture (Type 3) that has failed to heal properly, indicating a nonunion. The patient is presenting for ongoing treatment or management of this previously diagnosed and treated fracture.

Apply this code when documenting a patient encounter for a sacral nonunion, specifically a Type 3 fracture, after the initial treatment phase. This is appropriate for follow-up visits, surgical interventions for nonunion, or ongoing conservative management of the unhealed fracture.

• Ensure documentation clearly specifies a Type 3 sacral fracture and explicitly states "nonunion" for accurate code assignment.
• Verify that this is a "subsequent encounter" and not the initial treatment for the fracture.
• Always code the underlying cause of the fracture if known and applicable (e.g., osteoporosis, trauma).
