Spondylolisthesis, sacral and sacrococcygeal region

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

A condition where the sacrum or the small bone at the base of the spine (coccyx) slips or shifts, which is a less common location for this type of vertebral slippage.

Coding Tips

  • •This is a rare site for spondylolisthesis; carefully verify documentation to ensure correct anatomical location before coding
  • •Consider whether symptoms are truly from sacral/coccygeal involvement or from adjacent lumbar pathology
