Oth fracture of first lum vertebra, subs for fx w delay heal

This code signifies a fracture of the first lumbar vertebra, excluding a compression fracture, that is not healing at the expected rate. It indicates that the patient is receiving ongoing care for this specific vertebral injury after the initial treatment phase.

Apply this code when documentation specifies a non-compression fracture of the L1 vertebra with evidence of delayed union or nonunion. This is appropriate for follow-up encounters where the fracture has not fully consolidated within the typical timeframe, and the patient is undergoing continued management for the delayed healing process.

• Ensure the documentation clearly specifies "delayed healing" or "nonunion" for the L1 fracture.
• Verify that the fracture is explicitly stated as "other" or non-compression type.
• This code is for subsequent encounters; do not use for the initial treatment of the fracture.
