Anterior spinal artery compression syndromes, cervicothoracic region

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

What This Code Means

Compression of the anterior spinal artery at the junction between the neck and mid-back (cervicothoracic region), causing reduced blood flow to the spinal cord.

Coding Tips

  • •Cervicothoracic involvement indicates compression at the C7-T1 transition; ensure documentation specifies this region
  • •This location can be particularly problematic due to vascular anatomy in this transition zone
