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

This code signifies a fracture of the fifth lumbar vertebra where the specific type of fracture (e.g., compression, comminuted) is not documented. The patient is in a subsequent phase of care, and the fracture is not healing at the expected rate, indicating a complication in the recovery process.

This code is appropriate for follow-up encounters where a patient with a previously diagnosed, unspecified L5 vertebral fracture presents with evidence of delayed union or non-union. It should be used when the physician explicitly documents that the fracture is not healing as anticipated during ongoing treatment.

• Ensure documentation clearly states "delayed healing" or similar terminology for the fracture.
• Verify that the encounter is not for initial treatment or routine follow-up without healing complications.
• Confirm the fracture is specifically of the fifth lumbar vertebra and the type remains unspecified.
