Residential Mental Health and Substance Abuse Facilities (NAICS 62322)

A Histometrics industry primer for public-market and private investors.

Read this if you want the short version. NAICS 62322 is a five-digit industry in the North American Industry Classification System (NAICS, the federal code that defines U.S. industries). At this level it contains exactly one six-digit child — 623220, Residential Mental Health and Substance Abuse Facilities — so the two are effectively identical. This page gives the rollup's own ground-truth federal figures and the investor takeaways in brief. For full detail — scope, business models, per-diem economics, the company-by-company universe, and the regulatory landscape — see the 623220 primer.

1. Overview

This industry runs the places where people live around the clock while being treated for a mental-health condition or a substance use disorder (SUD): residential addiction "rehab," psychiatric residential treatment centers (RTCs) for adults and teens, halfway and sober-living houses, eating-disorder residences, and group homes.[1] The defining feature is that clients sleep there and receive room, board, supervision, and counseling — as distinct from an outpatient clinic they visit or a licensed hospital where medical care is the primary service.

It is a bed-based, labor-intensive service business whose returns hinge on occupied beds, clinical staffing, referrals, payer contracts, and collections. Demand is large, chronic, and rising, but the field is intensely fragmented and dominated by nonprofits, private-equity-backed roll-ups, and government agencies rather than public companies.[5][8]

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

NAICS nests: each five-digit industry rolls up one or more six-digit national industries. NAICS 62322 is a single-child case — it maps one-to-one onto:

Because there is only one child, the five-digit rollup and the six-digit industry share the same scope, the same establishments, and the same federal statistics. Everything the child primer says about scope — that this code excludes psychiatric/substance-abuse hospitals (NAICS 622210), outpatient clinics (NAICS 621420), and residences for intellectual and developmental disability (NAICS 623210) — applies unchanged here.[1] There is no additional activity to aggregate, so this page stays short and points to 623220 for the full treatment.

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

These are our ingested ground-truth federal statistics for NAICS 62322. Because the level has one child, they equal the 623220 figures.

(CBP = County Business Patterns, the Census establishment survey; HHI is a standard 0–10,000 market-concentration index where anything under 1,500 is "unconcentrated.") The four largest firms take under 10% of revenue and an HHI of 36 makes this about as fragmented as a U.S. industry gets — thousands of small operators, each with a handful of facilities.[3]

Undercount caveat. These figures understate the real footprint. CBP counts only employer establishments and excludes nonemployers and most government employees; the Economic Census centers on private employer firms.[2] That misses government-run psychiatric/SUD residences (government owns roughly one in ten SUD residences and nearly one in five mental-health ones) and a long tail of tiny nonprofit, faith-based, and owner-run halfway and sober-living homes.[5] Broader third-party estimates that fold in more of this activity put the wider "mental-health and substance-abuse centers" market nearer $30 billion. Treat the ~$21 billion federal receipts figure as the reliable floor for the residential-only slice, not the ceiling.[21]

4. The investable universe

Because the level equals its one child, all value concentrates in 623220 — and there is no pure public play in residential behavioral care. The closest listed exposure comes from operators whose beds skew toward hospitals and outpatient clinics rather than this code: Acadia Healthcare (ACHC, Nasdaq), the largest pure-play behavioral operator (residential treatment centers were only ~11% of its 2024 revenue), and Universal Health Services (UHS, NYSE), where behavioral is a large division inside a broader hospital company. Universal Health Realty Income Trust (UHT, NYSE) is a small real estate investment trust (REIT) landlord tied largely to UHS.[8][9] The genuinely residential market lives in private-equity-backed platforms (Discovery Behavioral Health, Newport Healthcare, Summit BHC, Pinnacle Treatment Centers, and others) and large nonprofits (Hazelden Betty Ford, Caron, Rogers Behavioral Health).[7][20][21] See the 623220 primer for the full company-by-company table.

5. How the money works

Residential facilities are a beds × occupancy × price business, closer in shape to a hotel or skilled-nursing home than to a physician practice:

Revenue ≈ occupied bed-days × collected rate per patient-day, plus ancillary clinical revenue.

Fixed costs (real estate, minimum staffing, licensing) are high, so profit is highly sensitive to occupancy — insurance-dependent centers often need 85–90%+ full beds to make money.[20] Payer mix is the single biggest margin driver: private/commercial insurance (higher, often out-of-network rates), Medicaid and government grants (lower but steady and expanding — the roll-up model's engine), and private/self-pay (the luxury-rehab and teen-RTC segment). Labor dominates costs — for context, salaries, wages, and benefits were 52.4% of Acadia's 2024 revenue (a company-specific figure, not an industry median).[8] Full per-diem, length-of-stay, and break-even detail is in the 623220 primer.

6. What drives demand

Behavioral-health need is enormous and largely unmet: in 2023, 20.4 million U.S. adults had both a substance use disorder and a mental illness, and 7.7 million received neither form of treatment during the year.[14] U.S. drug-overdose deaths, though down 26.2% to 79,384 in 2024, remain structurally elevated.[15] Insurance-parity law and Medicaid have shifted payment from out-of-pocket to third parties, and since 2015 Medicaid Section 1115 waivers have let states cover adult residential stays that the "Institution for Mental Diseases" (IMD) exclusion had blocked — steadily converting unpaid need into reimbursable volume.[10][16] The binding constraint is usually staff, not patients: most Americans live in a federally designated mental-health workforce-shortage area.[6]

7. Regulation

Oversight is heavy and mostly state-based: every facility is licensed by a state authority, and accreditation (The Joint Commission, CARF International) is often a condition of insurer and Medicaid participation.[6] The pivotal federal payment rules are the IMD exclusion and its 1115-waiver carve-outs.[16] The Mental Health Parity and Addiction Equity Act (MHPAEA) requires behavioral coverage to be no more restrictive than medical/surgical coverage, though its tightened 2024 final rule is now in litigation-driven non-enforcement.[10] Youth-facility oversight is tightening after abuse findings by the Government Accountability Office (GAO), via the federal Stop Institutional Child Abuse Act (2024) and California's Accountability in Children's Treatment Act.[18][19] The Department of Justice actively polices medically-unnecessary billing under the False Claims Act.[11][13]

8. Consolidation

Structurally fragmented and consolidating slowly. With a CR4 under 10% and an HHI of 36, no operator has national pricing power.[3] Consolidation runs on three tracks — strategic operators (Acadia, UHS) buying and building beds; private-equity (PE) roll-ups aggregating regional platforms; and joint ventures with hospital systems.[8] The durable nonprofit and government majority is largely not for sale, which caps how consolidated the field can become. PE's share is still modest (~6–7% of facilities nationally) but concentrated, and research indicates PE-owned residential facilities tend to charge more and offer fewer ancillary services.[7]

9. Risks

The headline risk is regulatory and reputational: Acadia paid a $19.85 million federal settlement in 2024 over medically-unnecessary billing and staffing allegations and faced press scrutiny over patient holds; UHS paid $122 million in 2020 to resolve False Claims Act allegations.[11][12][13] Scandal at one operator can trigger sector-wide payer and regulatory scrutiny. Other exposures: reimbursement/policy risk (Medicaid rate cuts, eligibility redeterminations, out-of-network crackdowns, the unsettled parity rule); chronic workforce shortages that cap beds and push wages up; clinical/safety/litigation risk with vulnerable patients; occupancy and referral volatility; and capital/leverage risk, especially for debt-financed PE platforms.[7][8][19]

10. How to invest, and the outlook

Public routes give only blended, indirect exposure — Acadia (ACHC), UHS, and the UHT REIT all mix hospital, outpatient, and residential economics; there is no listed pure play or ETF isolating residential behavioral care.[8][9] Private routes are where this industry actually lives: direct operating ownership of facilities or regional platforms, net-leased behavioral-health real estate, and private credit to operators — with site-level license, payer-contract, occupancy, and staffing diligence doing the real work. Note that the nonprofit and government majority of the field is not investable in the conventional sense.[5]

Outlook. Demand is a genuine secular tailwind (high unmet need, parity enforcement whenever it settles, Medicaid waivers expanding reimbursable volume), but three forces are likely to reward operational quality over financial engineering: a hard labor ceiling, reimbursement and Medicaid-policy uncertainty, and an intensifying spotlight on billing, youth facilities, and PE ownership.[7][10][14][16][18] The plausible path is continued slow consolidation, with winners pairing a durable (increasingly Medicaid-at-scale) payer mix with clean compliance, reliable staffing, and local density.
