Primary mixed sleep apnea of newborn

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

What This Code Means

A newborn experiences a combination of both obstructive and central sleep apnea episodes during sleep, where breathing stops due to both airway blockage and lack of breathing effort.

Coding Tips

  • •Mixed apnea involves both central and obstructive components; ensure documentation supports both types
  • •Verify this is primary (not secondary to another condition) before assigning this code
