An ICF facility, formally called an Intermediate Care Facility for Individuals with Intellectual Disabilities (ICF/IID), is a residential care setting that provides round-the-clock health services and training programs to people with intellectual or developmental disabilities. These facilities are funded through Medicaid as an optional state benefit, and their central purpose is helping residents gain as much independence and self-determination as possible through what federal regulations call “active treatment.”
Who ICF Facilities Serve
ICF/IID facilities specifically serve people with intellectual disabilities or closely related developmental conditions who need a structured, ongoing program of care. Admission isn’t based on a diagnosis alone. The person must require and be actively receiving a continuous treatment program tailored to their individual needs. Someone who is generally independent and can function with minimal supervision does not qualify for ICF-level care, even if they have an intellectual disability. The program is designed for individuals whose daily functioning, adaptive skills, or behavior requires consistent, hands-on support and training.
What Active Treatment Means
Active treatment is the defining feature of an ICF facility and what separates it from other residential care options. Federal regulations describe it as an individually tailored series of daily life experiences that serve as the primary opportunity for residents to develop functional skills and adaptive behaviors. This isn’t passive custodial care where someone simply lives in a supervised setting. Staff are required to implement training programs aggressively and consistently throughout each day.
Within 30 days of admission, an interdisciplinary team must complete a comprehensive assessment covering the person’s developmental strengths, personal preferences, adaptive skills they need to acquire, and any disabilities along with their causes when identifiable. From that assessment, the team builds an Individual Program Plan (IPP) with specific, measurable goals. Each goal must be written as a single behavioral outcome with a projected completion date, organized in a developmental progression that makes sense for that person.
The written training programs that carry out these goals must spell out the methods being used, who is responsible, how often data will be collected to track progress, and how inappropriate behaviors will be addressed and replaced with adaptive ones. This level of documentation exists because federal surveyors regularly inspect ICF facilities to verify that active treatment is genuinely happening, not just written on paper.
The Interdisciplinary Team and Key Staff
Every ICF resident’s care is managed by a team drawn from whatever professions and disciplines are relevant to that person’s needs. At the center of this team is a Qualified Intellectual Disabilities Professional, or QIDP. This person is responsible for integrating, coordinating, and monitoring each resident’s active treatment program.
To serve as a QIDP, someone must have at least one year of direct experience working with people who have intellectual or developmental disabilities. They also need to be a physician, registered nurse, or a human services professional holding at least a bachelor’s degree in a relevant field like special education, psychology, rehabilitation counseling, or sociology. The QIDP acts as the thread connecting all the different services a resident receives, making sure the various pieces of the program work together toward the goals in the IPP.
How ICF Facilities Are Funded
ICF/IID care is a Medicaid benefit, meaning the federal government shares the cost with each state that chooses to offer it. States are not required to include ICF/IID in their Medicaid programs, but most do. The reimbursement structure varies by state. Some states collect provider fees from ICF facilities that are then used to draw down additional federal matching funds. In Colorado, for example, intermediate care facilities pay fees into a dedicated state cash fund that supports their Medicaid reimbursement.
ICF care has historically been expensive. By 1993, the average cost of services in large state-run institutions reached $81,900 per resident per year, roughly $224 per day, which was 46% higher than it had been just seven years earlier. State-operated facilities consumed 62% of all ICF/IID spending that year despite serving a shrinking share of the total population. These high costs have been a major driver behind the shift toward smaller, community-based options.
Size and Setting: Large Institutions vs. Small Homes
ICF facilities range enormously in size. On one end are large state-run institutions, sometimes housed on campus-like settings called regional centers, that may serve hundreds of residents. On the other end are small community-based homes with as few as four to six beds, located in residential neighborhoods.
The landscape has shifted significantly over the decades. By the mid-1990s, 88% of all certified ICF/IID facilities had 16 or fewer beds. But that statistic is misleading on its own, because most residents still lived in larger settings. As of 1996, 63% of people served lived in facilities with 17 or more residents, and 57% lived in facilities serving more than 50 people. Small private facilities of 15 beds or fewer made up 66% of certified facilities as far back as 1986, yet access varied wildly by state. In 1992, just seven states accounted for 78% of the roughly 15,000 residents living in the smallest four-to-six person ICFs, while 20 states had no ICF facilities that small at all.
How ICFs Differ From Skilled Nursing Facilities
The distinction trips up a lot of people because the names sound similar. A Skilled Nursing Facility (SNF) provides continuous skilled nursing care to patients whose primary need is medical. SNFs operate with 24-hour inpatient nursing, physician services, dietary support, pharmaceutical services, and activity programs. They serve people recovering from surgery, managing complex medical conditions, or needing ongoing clinical monitoring.
An ICF, by contrast, serves people who need skilled nursing supervision and supportive care but do not require continuous nursing. The focus in an ICF/IID is not primarily medical. It is rehabilitative and developmental: building daily living skills, supporting communication, managing behavior, and fostering independence. The medical component exists to support those goals rather than being the central purpose of the stay.
The Shift Toward Community-Based Care
Since the late 1980s, there has been a steady nationwide decrease in the use of ICF/IID facilities, particularly large state-run institutions. Over 97% of large state institutions were certified as ICFs, but many have closed or downsized as states invest more heavily in Home and Community-Based Services (HCBS) waivers. These waivers allow Medicaid dollars to fund services for people with intellectual disabilities in their own homes or smaller community settings rather than institutional facilities.
This trend reflects a broader philosophy in disability services: that people with intellectual disabilities live fuller lives when integrated into their communities rather than segregated in institutional settings. Many states have actively transitioned residents out of large ICFs and into waiver-funded community programs. ICF/IID facilities still serve an important role for individuals whose needs are intensive enough to require the structured, 24-hour active treatment environment that federal regulations mandate. But the overall trajectory has been toward smaller settings and community integration for several decades.
