Unspecified fracture of first lumbar vertebra, sequela

This code signifies a long-term complication or late effect stemming from an unspecified fracture of the first lumbar vertebra. It indicates that the initial acute injury has resolved, but the patient is still experiencing residual problems directly attributable to that past fracture.

Use this code when documenting a patient presenting with ongoing symptoms or conditions (e.g., chronic pain, neurological deficits, spinal deformity) that are a direct consequence of a previously sustained, unspecified fracture of the L1 vertebra. This code is appropriate when the acute phase of the fracture has passed, and the patient is being treated for the sequelae.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., chronic pain, kyphosis).
• Ensure documentation clearly links the current condition to the previous L1 fracture.
• Avoid using this code for acute or subacute fractures; those require codes from the initial encounter or subsequent encounter categories.
