Industry Overview

Nursing and residential care facilities (NAICS 623) cover skilled nursing facilities (SNFs), assisted living communities, continuing care retirement communities (CCRCs), and residential centers for individuals with intellectual or developmental disabilities. The subsector serves over 4 million residents nationwide and generates roughly $280 billion in annual revenue, with Medicaid covering approximately 60% of all nursing home residents. Major operators include Brookdale Senior Living, the largest U.S. senior living company with over 670 communities, and Ensign Group, which manages more than 275 skilled nursing facilities concentrated in California, Texas, and Arizona. Federal oversight runs through CMS's nursing home Five-Star Quality Rating System, while states set their own Medicaid reimbursement rates and staffing ratio mandates. In 2023, CMS finalized a federal minimum staffing rule requiring 3.48 hours of nursing care per resident per day, a regulation that hit facilities in rural states like West Virginia and Arkansas hardest, where recruitment pools are thinnest. The sector's workforce of roughly 3.2 million direct-care workers faces chronic turnover exceeding 50% annually at many SNFs, driven by physically demanding work and median pay near $16 per hour.

Industry Trends

CMS

CMS's 2023 federal minimum staffing rule mandating 3.48 nursing hours per resident per day is forcing SNF operators to restructure labor models, with facilities in low-reimbursement states like Arkansas and Oklahoma facing the steepest compliance costs.

12.7M

Memory care units are the fastest-growing segment in assisted living, driven by the Alzheimer's Association's projection that Alzheimer's cases will reach 12.7 million by 2050, and operators like Sunrise Senior Living are building dedicated dementia wings to capture this demand.

03

Medicaid supplemental payment programs, particularly directed payment arrangements in Texas and quality incentive programs in Ohio, are reshaping facility revenue in states that have expanded these tools post-pandemic.

REIT

Real estate investment trusts including Sabra Health Care REIT and CareTrust REIT are acquiring distressed nursing home properties at discounts, separating real estate ownership from operations and creating new landlord-tenant dynamics that affect facility investment decisions.

PDPM

The PDPM (Patient-Driven Payment Model) reimbursement system, implemented by CMS for Medicare-covered SNF stays, is shifting operator strategy toward admitting higher-acuity patients with complex therapy and nursing needs rather than optimizing for therapy minutes.

Frequently Asked Questions

What is NAICS 623? ▾
NAICS 623 classifies facilities providing residential care combined with nursing or supervisory services. It includes skilled nursing facilities, assisted living communities, CCRCs, and residential care for individuals with developmental disabilities. Unlike NAICS 622 (hospitals), these facilities focus on long-term or indefinite-stay residential care rather than acute episodes.
How does CMS's Five-Star Quality Rating System work for nursing homes? ▾
CMS rates every Medicare/Medicaid-certified nursing home on a 1-to-5-star scale based on three components: health inspection results, staffing levels (registered nurse and total nursing hours per resident day), and quality measures including falls, pressure ulcers, and antipsychotic medication use. Facilities with one star face greater regulatory scrutiny and often struggle to attract private-pay residents.
What is the difference between skilled nursing and assisted living? ▾
Skilled nursing facilities (SNFs) provide 24-hour licensed nursing care, accept Medicare and Medicaid, and are regulated at the federal level under CMS. Assisted living communities offer personal care assistance and social activities but are regulated at the state level, with licensing requirements varying widely. Assisted living residents typically pay privately or through long-term care insurance; Medicaid coverage for assisted living exists in some states through Home and Community-Based Services waivers.
Why is nursing home staffing so difficult? ▾
Certified nursing assistants, who perform the majority of hands-on care, earn a median wage near $16 per hour while performing physically demanding work including lifting, bathing, and repositioning residents. Competition from hospitals, retail, and warehouse jobs offering comparable or higher wages without the physical toll drives turnover above 50% at many facilities. CMS's new staffing mandates intensify the pressure on rural operators with limited local labor pools.
How do Medicaid reimbursement rates affect nursing home quality? ▾
States set their own Medicaid nursing home rates, creating wide variation: in 2023, daily rates ranged from under $175 in some southern states to over $300 in New York. Research published in Health Affairs has linked lower reimbursement rates to worse staffing ratios, more health deficiencies, and higher hospitalization rates among residents, making state budget decisions a direct determinant of care quality.
