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

This code signifies a fracture of the first lumbar vertebra where the specific type of fracture (e.g., compression, burst) was not documented at the time of initial diagnosis. The "G" seventh character indicates that the patient is in the healing phase, but the bone union is progressing slower than expected.

This code is appropriate for follow-up encounters when a patient with a previously diagnosed, unspecified L1 vertebral fracture is experiencing delayed healing. This includes situations where imaging shows incomplete callus formation or persistent pain beyond the typical healing timeframe for such an injury.

• Ensure documentation clearly states "delayed healing" for the L1 fracture.
• Verify that the initial encounter for the fracture was coded with an appropriate "A" or "D" seventh character.
• Do not use if the specific type of L1 fracture is now known; instead, use the more specific fracture code with the "G" seventh character.
