Collapsed vertebra, NEC, lumbar region, init

This code signifies a vertebral body collapse in the lumbar spine that is not due to trauma, osteoporosis, or other specified conditions. It indicates a pathological fracture of a lumbar vertebra, often due to underlying disease processes like metastatic cancer or infection, and represents the initial treatment for this fracture.

Use this code when documentation clearly states a collapsed lumbar vertebra, not attributed to a specific cause like osteoporosis (M80.-) or acute trauma (S32.-), and the patient is receiving initial active treatment for the fracture. This code is appropriate for pathological fractures where the underlying cause is still being investigated or is not classifiable elsewhere.

• Ensure documentation specifies "initial encounter for fracture" to justify the 7th character 'A'. Subsequent encounters for healing would use 'D' or 'G', and sequela 'S'.
• Always code the underlying cause of the pathological fracture (e.g., malignancy, infection) first, if known, as this code describes the manifestation.
• Differentiate from traumatic fractures (S32.-) and osteoporotic fractures (M80.-), which have their own specific codes.
