Nursing Care Facilities (Skilled Nursing Facilities) — U.S. Industry-Group Primer

NAICS 2022 code 62311

Short primer — single-child pass-through. At the five-digit level, NAICS industry 62311 contains exactly one six-digit national industry, 623110 (Nursing Care Facilities (Skilled Nursing Facilities)). The two codes cover the same establishments and the same economics, so this level is its child. This page gives the rollup definition, the ground-truth federal figures for the 62311 aggregate, and a map of where value sits. For the full treatment — payer mix, reimbursement mechanics, the named public operators and REITs, regulation, and outlook — read the 623110 primer.

1. Overview

Skilled nursing facilities (SNFs), commonly called nursing homes, provide 24-hour inpatient nursing and personal care for people who cannot live independently — both frail long-stay residents whose care is largely custodial and shorter-stay patients recovering from a hospital surgery, stroke, or serious illness. It is a large, essential, government-funded, and politically charged corner of health care.[1]

The North American Industry Classification System (NAICS) organizes this activity in a strict hierarchy. The five-digit code 62311 is a NAICS industry; the six-digit codes beneath it are national industries. Here there is only one national industry — 623110 — so 62311 and 623110 describe an identical population of establishments. Everything an investor needs to know about the business itself lives at the child level; this page exists to record the rollup figures and hand off.

2. What's inside — and why the level equals its one child

NAICS 62311 has a single child:

Because there is a one-to-one mapping, no aggregation is happening at this level — the five-digit total simply is the six-digit total. That means there is no internal mix to analyze, no cross-child comparison to draw, and no rollup adjustment to make. The value of the 62311 label is taxonomic: it slots skilled nursing into the broader 623 Nursing and Residential Care Facilities subsector alongside distinct siblings such as continuing-care retirement communities and assisted living (62331), residential intellectual/developmental-disability and mental-health/substance-abuse facilities (6232), and other residential care (6239). Those adjacent codes are separate industries, not part of 62311.[1]

For the full definition of what counts as an SNF (and what is deliberately excluded — assisted living, home health, hospitals), see Section 2 of the 623110 primer.

3. How big it is (this level's rollup figures)

The figures below are our federal ground truth for the 62311 aggregate. Because the level has one child, they are identical to 623110's. They carry different vintages: County Business Patterns (CBP) is 2023; receipts and concentration data are from the 2022 Economic Census.

Undercount caveats. The Economic Census generally excludes government-operated establishments, so the roughly 5–6% of nursing homes run by counties and municipalities are missing from the $135.4 billion receipts figure; CBP likewise omits most government employees.[4] The receipts total is also smaller than the ~$211 billion of national spending on nursing-care facilities that the Centers for Medicare & Medicaid Services (CMS) reports for 2023, because that broader spending measure is a later vintage and bundles in nursing revenue from continuing-care communities.[5] Treat the federal receipts figure as a conservative floor. Ownership here is heavily private, family, private-equity, and nonprofit — so any count keyed to public filings understates the true footprint. These federal statistics do not provide nationwide beds, occupancy, payer mix, or margins; those appear in the 623110 primer where separately sourced.

4. The investable universe (where value concentrates)

With a single child, all of the sector's investable value sits in one place — there is no allocation decision to make across children, only within skilled nursing. That universe splits two ways, and both public- and private-market investors participate:

• Operators run the facilities and carry the reimbursement, labor, and occupancy risk. The listed group is unusually thin for an industry this size — Ensign Group (ENSG), PACS Group (PACS), and National HealthCare (NHC) — because most beds are privately held.
• Landlord real estate investment trusts (REITs) own the buildings and lease them to operators, typically under long-term triple-net leases. This is the more income-oriented route: Omega Healthcare (OHI), CareTrust (CTRE), Sabra (SBRA), National Health Investors (NHI), and LTC Properties (LTC).

The largest chains — Genesis HealthCare, Life Care Centers of America, PruittHealth, and others — are private. For the full ticker-by-ticker table (scale, revenue, market cap) and the roster of major private and nonprofit owners, see Section 4 of the 623110 primer.

5. How the money works

An SNF's revenue is patient-days × the daily rate for each payer, so occupancy, payer/skilled mix (the share of higher-paying Medicare and managed-care days versus low-margin Medicaid days), and government reimbursement rates drive the business. Labor is the dominant cost, and margins are thin — the Medicare Payment Advisory Commission (MedPAC) reported a 22% fee-for-service Medicare margin against a 0.4% all-payer margin, meaning a facility can be full and still lose money if its skilled mix is too low. Real-estate investors instead earn contractual rent and watch the operator's rent-coverage ratio. Section 5 of the 623110 primer works through the payment mechanics — the Patient-Driven Payment Model (PDPM), Medicaid rate-setting, and lease structures — in full.

6. What drives demand

The long tailwind is demographic: the U.S. 85-and-older population most likely to need nursing care is projected to roughly double, from about 9 million around 2030 to about 14 million by 2040. Short-stay demand tracks hospital discharge volume. The headwinds are substitution and steering — home health, assisted living, and especially Medicare Advantage plans divert or shorten stays — and a labor ceiling, since staffing shortages can keep beds empty even when demand exists. See Section 6 of the 623110 primer.

7. Regulation

Regulation is the industry's defining feature because the government both pays and polices it: CMS sets Medicare rates and certifies facilities, states set Medicaid rates, and quality is enforced through inspections, the Five-Star rating on Care Compare, and payment-adjustment programs. A first-ever federal minimum-staffing mandate was finalized in 2024, partly vacated by a Texas court in 2025, placed under a 10-year moratorium by the 2025 reconciliation law, and formally repealed in December 2025 — removing a major cost overhang. Certificate-of-Need (CON) laws cap new beds in many states. Full detail in Section 7 of the 623110 primer.

8. Consolidation

At the national level the industry is strikingly fragmented — and, with one child, the level's concentration figures are the industry's own:

Source: 2022 Economic Census [3]. An HHI of 21 is effectively zero: no operator dominates nationally. But competition is local — patients choose facilities near family and hospitals refer to nearby SNFs, so a chain with tiny national share can dominate a single county. Consolidation is steady and tilts toward the well-capitalized, who buy distressed and nonprofit sellers. See Section 8 of the 623110 primer.

9. Risks

The dominant risk is reimbursement and policy — revenue depends on government rates the operator cannot set, and federal or state Medicaid pressure (including limits on provider-tax financing) could squeeze the low-margin base. Other core risks: chronic labor shortages and agency-staffing cost, low occupancy against fixed costs, leverage and rent burden on thin margins (Genesis HealthCare's July 2025 bankruptcy is the cautionary tale), payer steering by Medicare Advantage, and quality, litigation, and ownership-opacity exposure. REIT investors additionally carry tenant-credit and interest-rate risk. Full list in Section 9 of the 623110 primer.

10. How to invest and outlook

Public investors can separate the two businesses: operators (ENSG, PACS, NHC) carry full operating exposure, while landlord REITs (OHI, CTRE, SBRA, NHI, LTC) offer rent-based income at lower operational risk. Because so few public operators exist, most capital enters privately — direct ownership and operation, real-estate roll-ups, sale-leasebacks, and lending to operators — which demands hands-on operating and regulatory expertise.

Outlook. The demographic tailwind is close to a certainty and new supply is constrained by CON laws and years of underbuilding, so occupancy and pricing power should firm over time; the staffing-mandate repeal lifted a cost overhang. The central near-term risk is Medicaid funding. In short, a durable demand story wrapped around persistent, policy-driven margin risk — rewarding to disciplined operators and landlords, unforgiving to the over-leveraged.
