An intermediate care facility for individuals with intellectual disabilities (ICF/IID) is a Medicaid-funded institution that must provide “active treatment” and meet the federal conditions of participation in 42 CFR Part 483, Subpart I, along with its state's Medicaid certification rules. This page is for organizations operating or developing an ICF/IID that are entering Medicaid certification or bringing an operating program into line with the conditions. Integral Healthcare Solutions (IHS) builds your ICF/IID policies and certification evidence; your qualified professionals approve the active-treatment content.

What is an ICF/IID?

CMS's ICF/IID page states: “The ICF/IID benefit is an optional Medicaid benefit. The Social Security Act created this benefit to fund ‘institutions’ (4 or more beds) for individuals with intellectual disabilities, and specifies that these institutions must provide ‘active treatment,’ as defined by the Secretary.” The same page reports: “Currently, all 50 States have at least one ICF/IID facility. This program serves over 100,000 individuals with intellectual disabilities and other related conditions.”

The governing text is 42 CFR Part 483, Subpart I, “Conditions of Participation for Intermediate Care Facilities for Individuals with Intellectual Disabilities” (§§ 483.400 to 483.480), read as current in the eCFR on September 30, 2026. Its conditions include “§ 483.410 Condition of participation: Governing body and management” and “§ 483.420 Condition of participation: Client protections.” Your state's Medicaid certification and licensure rules apply as well; they vary by state and this page does not summarize them.

Three provisions shape most of the operating program:

• Active treatment. “Each client must receive a continuous active treatment program, which includes aggressive, consistent implementation of a program of specialized and generic training, treatment, health services and related services” (42 CFR 483.440(a)(1)).
• Professional oversight. “Each client's active treatment program must be integrated, coordinated and monitored by a qualified intellectual disability professional” (42 CFR 483.430(a)).
• Planning deadline. “Within 30 days after admission, the interdisciplinary team must prepare for each client an individual program plan that states the specific objectives necessary to meet the client's needs” (42 CFR 483.440(c)(4)).

Who needs it and what triggers it

An ICF/IID serves people who need continuous active treatment and who qualify for Medicaid. Of the individuals served, CMS's page states: “All must qualify for Medicaid assistance financially.” The regulation also draws a line on who the program is for: “Active treatment does not include services to maintain generally independent clients who are able to function with little supervision or in the absence of a continuous active treatment program” (42 CFR 483.440(a)(2)).

The usual triggers are:

• A new facility entering Medicaid certification as an ICF/IID, which needs its governing body, client protection and active-treatment documentation in place before certification.
• An operating ICF/IID whose program needs remediation, for example individual program plans that are not completed within 30 days of admission or active-treatment records that do not show coordination by a qualified intellectual disability professional (QIDP).
• Enrollment or revalidation. The CY 2026 Medicare, Medicaid and CHIP application fee notice names ICF/IID among Medicaid-only institutional providers (see the cost section below).

How IHS helps

IHS works from the conditions of participation outward to your evidence. The process:

1. A gap assessment against the ICF/IID conditions of participation in 42 CFR Part 483, Subpart I, and your state's Medicaid certification rules, with questionnaires on residents, staffing and records.
2. Document and evidence mapping: a crosswalk from each condition to the policy, record or data that shows it is met.
3. Drafting client rights, grievance, interdisciplinary review and documentation procedures, with active-treatment content for your QIDP and clinicians to review and approve.
4. A mock survey against the conditions.
5. Readiness support, including drafted correspondence for your organization to review and send. IHS drafts; your organization submits.

Your organization supplies resident and staffing data, current policies, sample individual program plans, and QIDP and clinician approval.

The limit: active treatment design is clinical work your professionals own. IHS drafts the procedures and documentation around it and does not design a client's treatment. Physical-plant and life-safety survey items need your facilities staff. For accreditation work, see accreditation consulting; other compliance services are listed under compliance services.

What to have ready

Each item ties to 42 CFR Part 483, Subpart I (eCFR, current as of September 30, 2026) or to CMS's ICF/IID page (last modified April 21, 2025).

• Your bed count, since CMS describes the benefit as funding “institutions” of 4 or more beds (CMS page).
• How you confirm each client's financial eligibility for Medicaid, since “All must qualify for Medicaid assistance financially” (CMS page).
• Admission criteria that address 483.440(a)(2), which excludes from active treatment services to maintain generally independent clients.
• The names and roles of your qualified intellectual disability professionals, and how each client's program is “integrated, coordinated and monitored” (483.430(a)).
• Sample individual program plans with admission dates, showing each plan was prepared within 30 days after admission (483.440(c)(4)).
• Records showing each client receives “a continuous active treatment program” (483.440(a)(1)).
• Governing body and management documents (§ 483.410).
• Client protection policies, including rights and grievance procedures (§ 483.420).
• Staffing data and your current policy manual, to crosswalk against each condition in Subpart I.
• Your state's Medicaid certification and licensure requirements, which vary by state.

How it compares

CMS frames the ICF/IID benefit against a shift in how services are delivered. Its ICF/IID page states: “Emphasis is now on people living in their own homes, controlling their own lives and being an integral part of their home community.” Medicaid home and community-based services are another model organizations consider; this page does not cover their rules, and the choice between the models depends on your clients, your state and your Medicaid agency's programs.

A nursing facility is a separate Medicaid institutional category. The CY 2026 application fee notice lists “nursing facilities, intermediate care facilities for persons with intellectual disabilities (ICF/IID), and psychiatric residential treatment facilities” as distinct Medicaid-only institutional providers. Each has its own federal conditions.

What it costs

The published federal fee is the provider enrollment application fee. The Federal Register notice of December 3, 2025 (2025-21877) states that “Medicaid-only and CHIP-only institutional providers would include nursing facilities, intermediate care facilities for persons with intellectual disabilities (ICF/IID), and psychiatric residential treatment facilities,” and announces “a $750.00 calendar year (CY) 2026 application fee for institutional providers that are initially enrolling in the Medicare or Medicaid program or the Children's Health Insurance Program (CHIP); revalidating their Medicare, Medicaid, or CHIP enrollment; or adding a new Medicare practice location.” Verify current fees with CMS and with your state Medicaid agency. We did not review state licensure or certification fees for this page; they vary by state. IHS scopes each engagement after a free introductory call.

What this is not

• It is not legal advice. Medicaid eligibility, licensure and reimbursement questions go to your counsel.
• It is not a guarantee of certification or of any survey result.
• It is not clinical treatment design. IHS does not submit anything to CMS or your state on your behalf; IHS drafts and your organization submits.

Frequently asked questions

What is an ICF/IID and who does it serve?

An ICF/IID is an intermediate care facility for individuals with intellectual disabilities. CMS describes the benefit as funding institutions of 4 or more beds for individuals with intellectual disabilities that must provide active treatment. CMS reports that all 50 states have at least one ICF/IID and that the program serves over 100,000 individuals with intellectual disabilities and other related conditions.

Is ICF/IID a Medicare or a Medicaid program?

It is Medicaid. CMS states that the ICF/IID benefit is an optional Medicaid benefit, and that all individuals served must qualify for Medicaid assistance financially. The federal conditions of participation are in 42 CFR Part 483, Subpart I.

What does active treatment mean in an ICF/IID?

Under 42 CFR 483.440(a)(1), each client must receive a continuous active treatment program that includes aggressive, consistent implementation of a program of specialized and generic training, treatment, health services and related services. Under 483.440(a)(2), active treatment does not include services to maintain generally independent clients who can function with little supervision.

What is a qualified intellectual disability professional (QIDP) and what do they do?

Under 42 CFR 483.430(a), each client's active treatment program must be integrated, coordinated and monitored by a qualified intellectual disability professional. IHS drafts the documentation around that role; your QIDP approves the active-treatment content.

How soon after admission must the individual program plan be completed?

Within 30 days. Under 42 CFR 483.440(c)(4), the interdisciplinary team must prepare an individual program plan for each client within 30 days after admission, stating the specific objectives necessary to meet the client's needs.

What are the ICF/IID conditions of participation?

They are the federal requirements in 42 CFR Part 483, Subpart I, sections 483.400 through 483.480. They include conditions on governing body and management (483.410), client protections (483.420), and the provisions on the qualified intellectual disability professional (483.430(a)) and active treatment (483.440). Your state's Medicaid certification rules apply alongside them.

ICF/IID versus home and community-based waiver services: which model should we develop?

That is your organization's decision, made with your state Medicaid agency's programs in view. CMS's ICF/IID page notes that emphasis is now on people living in their own homes, controlling their own lives and being part of their home community. This page does not cover the rules for home and community-based services.

What client protections must an ICF/IID have?

Subpart I includes a condition of participation titled Client protections at 42 CFR 483.420. Read its full text for the specific requirements. IHS drafts client rights and grievance procedures against that condition for your organization to adopt.

Is there an enrollment application fee for an ICF/IID?

The CY 2026 Federal Register fee notice names ICF/IID among Medicaid-only institutional providers and sets a $750.00 application fee for institutional providers initially enrolling, revalidating, or adding a new Medicare practice location. Verify current fees with CMS and with your state Medicaid agency.
