Unsp fx third lum vertebra, subs for fx w delay heal

This code signifies a fracture of the third lumbar vertebra where the specific type of fracture (e.g., compression, burst) is not documented. The patient is in a subsequent phase of care, and the fracture is experiencing delayed healing, meaning it is taking longer than expected to unite.

This code is appropriate for follow-up encounters when a patient with an unclassified L3 vertebral fracture is being monitored for healing progress, and the physician explicitly documents delayed union. It would be used after the initial treatment phase, but before the fracture has fully healed or progressed to nonunion.

• Ensure documentation clearly states "delayed healing" for the L3 fracture.
• Verify that the encounter is not for initial treatment or routine follow-up of a healing fracture.
• Confirm the fracture site is specifically the third lumbar vertebra and not another lumbar segment.
