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

This code indicates an unspecified fracture of the first lumbar vertebra that is currently undergoing routine healing. It signifies that the initial treatment has been rendered, and the patient is now in a recovery phase without complications or delayed healing.

This code is appropriate for follow-up encounters where a patient with a previously diagnosed L1 vertebral fracture is progressing as expected. It applies when the fracture is healing routinely, and the focus of the visit is on monitoring recovery, pain management, or physical therapy during the healing phase.

• Ensure documentation specifies "subsequent encounter" and "routine healing."
• Verify the fracture site is specifically the first lumbar vertebra (L1).
• Do not use for initial encounters, nonunion, malunion, or delayed healing.
