High-intensity neurologic impairment (HI-NI) codes can be used to identify neurological diagnoses that are expected to last 12 months or longer and result in significant functional impairments requiring subspecialty medical care.
Specifically, HI-NI includes conditions that:
- Involve the central and/or peripheral nervous system.
- Can be reasonably expected to last at least 12 months (unless death intervenes).
- Results in systemic and/or multi-system physiologic impairment requiring pediatric specialty care.
