Understanding assisted living in Missouri
Assisted living gives an older adult a private apartment or room plus help with the daily activities that have become hard — bathing, dressing, medication management, and meals — without the round-the-clock medical care of a nursing home.
Missouri licenses these communities under a three-tier system administered by the Department of Health and Senior Services (DHSS), Section for Long-Term Care Regulation, under Chapter 198 RSMo and 19 CSR 30-86: Residential Care Facility I (RCF I) for the lowest acuity, Residential Care Facility II (RCF II) for moderate acuity, and Assisted Living Facility (ALF) for the highest acuity of the three non-skilled categories. A typical monthly range is $3,400 to $5,200 a month.
Here's what separates a strong community from a weak one:
- the all-in monthly rate for your parent's specific care tier, in writing
- the awake-overnight staffing ratio, not just the daytime number
- what change in condition would force a move to a higher level of care
