CARF Partial Hospitalization Program Accreditation: Frequently Asked Questions
Last updated: October 2026
Answers to questions from partial hospitalization programs, day hospitals, and behavioral health organizations preparing for CARF accreditation.
What is CARF accreditation for a partial hospitalization program?
CARF (Commission on Accreditation of Rehabilitation Facilities) accreditation for a PHP is a voluntary third-party recognition that your program conforms to CARF's Behavioral Health Standards for partial hospitalization services. A CARF surveyor team visits your organization, reviews documentation, interviews staff and persons served, and evaluates conformance across governance, human resources, clinical services, quality improvement, and person-served rights. Accreditation is awarded for one or three years depending on the level of conformance demonstrated.
Is CARF accreditation required for a partial hospitalization program?
CARF accreditation is not universally required by law to operate a PHP. Some payers, state licensing bodies, and referral networks require or prefer it, and some managed care organizations and state Medicaid programs require CARF (or equivalent) accreditation as a condition of PHP network participation. Some states list CARF as an approved accreditation body for behavioral health program licensure.
What CARF standards apply to a partial hospitalization program?
PHPs are evaluated under CARF's Behavioral Health Standards Manual, which includes both the core organizational standards (governance, leadership, human resources, health and safety, quality improvement) and the program-specific standards for partial hospitalization. Program standards address clinical intensity, interdisciplinary staffing, individualized treatment planning, discharge planning initiated at admission, outcome measurement, and person-served rights. The 2025–2026 standards manual (effective July 1, 2025) includes updates to Section 2 standards that PHP programs should review before their next survey.
How does CARF define a partial hospitalization program?
CARF defines a partial hospitalization program as a time-limited, therapeutically intensive ambulatory treatment program providing comprehensive clinical services during day or evening hours as an alternative to or step-down from inpatient care. It is distinct from intensive outpatient treatment in the level of clinical intensity, staffing requirements, and the acuity of persons appropriately served. CARF's 2026 Behavioral Health Program Descriptions document provides the authoritative current definition.
What is the difference between a CARF PHP and a CARF IOP accreditation?
Both PHP and IOP are distinct program types in CARF's behavioral health taxonomy, each with its own standards requirements. PHP accreditation covers programs providing more structured clinical hours per week, with an interdisciplinary team and psychiatric oversight during program hours. IOP accreditation covers programs of lesser intensity, where the person is expected to manage more independently between sessions. A program cannot substitute one designation for the other; the services delivered must match the accreditation designation sought.
How does CARF PHP accreditation relate to the ASAM Criteria?
This page does not map CARF program types to ASAM levels. The ASAM Criteria are published by the American Society of Addiction Medicine (ASAM). See asam.org. Programs that bill payers under level-of-care criteria should build documentation that supports both CARF conformance and the payer's criteria.
What staffing does CARF require for a partial hospitalization program?
CARF requires that PHP staffing be appropriate to the acuity of persons served and the services provided. At minimum, PHP surveyors expect an interdisciplinary treatment team that includes licensed clinical staff, psychiatric or physician oversight available during program hours, and nursing presence commensurate with the medical complexity of the population. CARF does not mandate specific staff-to-client ratios universally, but its standards require documented evidence that staffing levels support individualized treatment planning and crisis response. State licensing requirements can impose additional staffing minimums.
How long does CARF PHP accreditation last?
CARF awards accreditation at two levels: Three-Year Accreditation, granted to organizations demonstrating substantial conformance across CARF standards; and One-Year Accreditation, granted when an organization meets core standards but has identified areas requiring improvement. Three-year is the standard goal. A one-year outcome means there are gaps to remediate before the renewal survey. Organizations receiving one-year accreditation must address cited deficiencies and demonstrate improvement within the accreditation period.
What does a CARF PHP survey involve?
A CARF survey for a partial hospitalization program involves an on-site visit by one or more surveyors with behavioral health expertise, for a number of days that depends on program size and complexity. Surveyors review organizational documents (policies, strategic plans, QI reports, personnel files), observe the physical environment, interview leadership, staff, and persons served, and assess conformance across all applicable standards. The survey results in a written accreditation decision with any cited Areas for Improvement or Recommendations. Organizations receiving Areas for Improvement must submit a Quality Improvement Plan addressing corrective actions.
Which gaps can lead to CARF findings in PHP surveys?
Gaps that can lead to findings include: outcome data collected but not trended across periods or used in quality improvement decisions; strategic plans with goals disconnected from measurable performance data; discharge planning that begins too late in the treatment episode rather than at admission; personnel file gaps such as lapsed license verifications or missing clinical supervision documentation; grievance process failures where patients cannot describe the process when interviewed; and treatment plans that are formulaic rather than individually tailored and collaboratively developed.
How much does CARF charge to accredit a partial hospitalization program?
Published by CARF in the annual fee schedule (carf.org). Verify current fees with CARF directly, as fees are updated annually. The total CARF fee depends on the number of surveyors and survey days required, which varies based on organizational size and program complexity.
Can a PHP hold both CARF accreditation and Joint Commission accreditation?
Yes. CARF and The Joint Commission are separate accreditation bodies, and a program can hold accreditation from both. A PHP may hold both to meet different payer requirements, since hospital systems and payers differ in which accreditation they prefer or require. The two bodies' standards, survey processes and specific requirements differ. An organization considering both can weigh the added survey and reporting work against the payer or market access gained. IHS's PHP work covers CARF accreditation. IHS does not market Joint Commission readiness for partial hospitalization programs.
Does CARF accreditation cover telehealth or virtual PHP services?
CARF's behavioral health standards can apply to telehealth-delivered services, including virtual PHP programs. Programs delivering PHP services via telehealth should document their technology infrastructure, privacy protocols, crisis response procedures for remote participants, and clinical rationale for telehealth suitability in their standards evidence. CARF surveyors evaluate telehealth services against the same core standards with attention to how remote delivery affects access, safety, and person-centered care.
How should a PHP prepare for a CARF survey?
Effective preparation involves four parallel workstreams: (1) Gap analysis — a structured review of all applicable CARF standards against current policies, procedures, and documentation to identify deficiencies before the surveyor does. (2) Document remediation — updating policies, building QI reports with trended data, auditing and completing personnel files. (3) Staff preparation — coaching staff who will be interviewed so they can accurately describe program processes, rights, and grievance procedures. (4) Physical environment review — ensuring health and safety requirements are visible and documented.
What does CARF recommend before a survey, and what happens after it?
CARF suggests a self review of the program against its standards as a way to gauge survey readiness (CARF, Steps to Accreditation, page opened October 4, 2026). That self study is a step the organization takes itself before it applies. CARF's timeline after the survey runs roughly six to eight weeks to a decision and written report, a certificate within 60 days of the decision, a Quality Improvement Plan due within 90 days of being notified of the decision, and an Annual Conformance to Quality Report after accreditation is achieved (CARF, Steps to Accreditation, page opened October 4, 2026).
