Stable burst fx unsp lum vertebra, subs for fx w delay heal

This code signifies a burst fracture of an unidentifiable lumbar vertebra that is considered stable, meaning there is no significant spinal instability. The patient is in a subsequent phase of care, and the fracture is experiencing delayed healing, indicating the bone is not mending at the expected rate.

Apply this code when a patient with a previously diagnosed stable burst fracture of an unspecified lumbar vertebra presents for follow-up care, and imaging or clinical assessment confirms that the fracture healing process is slower than anticipated. This is appropriate for ongoing management of the delayed union, not for the initial injury or routine healing.

• Ensure documentation clearly states "delayed healing" and specifies a "subsequent encounter" for the fracture.
• Verify that the specific lumbar vertebra involved was not identified in the initial diagnosis or subsequent documentation.
• Do not use this code for nonunion; a different code would be appropriate for a complete failure of bone healing.
