Background

Skilled hourly nursing care (medically intensive home nursing) refers to complex hourly nursing services provided by a licensed nurse in the individual's home for more than 4 hours/day. These services are intended as an alternative to a more acute care setting (for example, hospital or skilled nursing facility) or to assist with transition from an acute setting, and include care such as ventilator, tracheostomy, IV therapies, and other intensive interventions.

Definitions: see Definitions section for terms such as medically intensive home care, medically fragile, and private duty nursing. This service is an alternative to inpatient care and the policy emphasizes that the goal is to train family/caregivers and gradually decrease nursing care hours over time, with most cases covered for 8 to 12 continuous hours per day (less than 16 hours) unless transitional ventilator/tracheostomy exceptions apply.
