Oth fracture of fifth lum vertebra, subs for fx w nonunion

This code signifies a patient presenting for follow-up care of a previously diagnosed fracture in the fifth lumbar vertebra, excluding a compression fracture. The key characteristic for using this code is the documentation of a nonunion, meaning the bone has failed to heal properly after the initial injury.

This code is appropriate for patients undergoing ongoing management for a nonunion of a fifth lumbar vertebral fracture (other than compression). This includes scenarios such as surgical intervention for nonunion, casting/bracing adjustments, or physical therapy aimed at promoting healing or managing complications related to the unhealed fracture.

• Ensure documentation explicitly states "nonunion" and specifies the "fifth lumbar vertebra" and "other fracture" type.
• Verify this is a "subsequent encounter" for the fracture, not the initial treatment.
• Do not use for malunion, which implies healing in an incorrect position, or for initial fracture treatment.
