Unstbl burst fx second lum vert, subs for fx w delay heal

This code signifies an unstable burst fracture affecting the second lumbar vertebra, indicating a severe injury where the vertebral body is crushed in multiple directions. The "unstable" nature implies a high risk of spinal cord or nerve root compression, and "delayed healing" means the fracture is not consolidating within the expected timeframe.

This code is appropriate for subsequent encounters when a patient with a previously diagnosed unstable burst fracture of the L2 vertebra is receiving ongoing treatment for the fracture, and the healing process is progressing slower than anticipated. This includes follow-up appointments, imaging studies, or interventions specifically addressing the delayed union of the fracture.

• Ensure documentation clearly specifies "unstable burst fracture" of the L2 vertebra and explicitly mentions "delayed healing."
• This code is for subsequent encounters only; an initial encounter for this fracture would use a different seventh character.
• Always review the entire medical record to confirm the specific vertebra involved and the healing status.
