Collapsed vertebra, NEC, occipt-atlan-ax region, sqla

This code signifies a collapsed vertebra in the occipito-atlanto-axial region (C0-C2) that is a long-term complication or residual effect of a previously sustained fracture. It indicates a chronic structural change rather than an acute injury. The collapse is not attributable to other specific conditions like osteoporosis or tumor.

Apply this code when documentation clearly states a collapsed vertebra in the upper cervical spine (C0-C2) as a sequela of a healed or past fracture. This code is appropriate for follow-up care, chronic pain management, or evaluation of long-term neurological deficits directly resulting from the vertebral collapse post-fracture. Documentation should specify the region and the causal link to a prior fracture.

• Ensure documentation explicitly states "sequela of fracture" or similar phrasing indicating a chronic condition rather than an acute event.
• Do not use for acute fractures; instead, refer to the S12 category for current injuries.
• This code requires a seventh character "S" for sequela, indicating the late effect of the fracture.
