Unspecified fracture of fourth lumbar vertebra, sequela

This code signifies a long-term complication or late effect stemming from an unspecified fracture of the fourth lumbar vertebra. It indicates that the original fracture has healed, but the patient continues to experience residual issues directly attributable to that past injury.

Apply this code when documenting a patient presenting with chronic pain, deformity, neurological deficits, or other ongoing problems that are a direct consequence of a previously sustained, but now healed, L4 vertebral fracture. This is used after the acute phase of the fracture has passed.

• Always use a "sequela" code as a secondary diagnosis, following the code for the specific manifestation of the sequela (e.g., chronic pain, kyphosis).
• Ensure documentation clearly links the current condition to the past L4 fracture.
• Avoid using this code for active, acute fractures; those require codes from the initial encounter or subsequent encounter categories.
