Unstbl burst fx unsp lum vertebra, subs for fx w routn heal

This code signifies an unstable burst fracture affecting an unspecified lumbar vertebra, indicating a severe injury where the vertebral body is crushed in multiple directions. "Unstable" implies a high risk of spinal cord or nerve root compromise, while "burst" describes the comminuted nature of the fracture.

Use this code for follow-up encounters where a patient with a previously diagnosed unstable burst fracture of an unspecified lumbar vertebra is receiving routine care during the healing phase. This includes routine office visits, imaging reviews, and physical therapy sessions aimed at monitoring healing and recovery.

• Ensure documentation specifies "unstable burst fracture" and "unspecified lumbar vertebra" for accurate code assignment.
• The "D" seventh character indicates a subsequent encounter for a fracture with routine healing; do not use for initial treatment or delayed/nonunion healing.
• Always review the medical record for laterality or specific vertebral level if available, as more specific codes exist.
