The Early and Periodic Screening, Diagnostic, and Treatment (EPSDT) benefit is the heart of Medicaid’s coverage for children, and something we have been tracking for a long time. As highlighted in past blog posts, the Centers for Medicare & Medicaid Services’ (CMS) released a landmark state health official letter in 2024 followed up by issuance of a behavioral health toolkit this past February. Much of this activity is in response to the 2022 Bipartisan Safer Communities Act (BSCA), which directed CMS to help states strengthen their implementation of EPSDT services and oversight. And last month, CMS added another important piece. On May 13, 2026, it announced an updated EPSDT Coverage Guide—EPSDT: A Guide for States: Coverage in the Medicaid Benefit for Children and Adolescents (May 2026). The update matters because it refreshes, for the first time since 2014, the document that states, health plans, providers, and advocates have relied on for more than a decade to understand the scope of the children’s benefit.
Like its predecessor, the 2026 Guide does not establish new EPSDT policy; CMS describes it as a technical assistance resource that “compiles decades of guidance in one place” for EPSDT staff working in state Medicaid agencies. But this is far more than a reprint. The Guide reorganizes the material, folds in guidance issued since 2014 (including the post-BSCA work and the recent behavioral health guidance), and adds entirely new sections, among them dedicated discussions of health homes, interagency coordination, and a standalone section on state and federal quality reporting and monitoring of EPSDT. Below are the top lines, along with a few places where the Guide could have gone further.
The Big Picture: The Right Care, to the Right Child, at the Right Time, in the Right Setting
The Guide opens by reaffirming what has always driven the benefit: “The goal of EPSDT is to ensure that individual children get the health care they need when and where they need it—the right care to the right child at the right time in the right setting.” It also restates states’ affirmative obligations to ensure that “Medicaid-eligible children and their families are informed of what they are entitled to under EPSDT, have access to required screenings, and can obtain necessary diagnostic and treatment services to correct or ameliorate identified conditions in a timely way.” Informing families is not optional; it is a precondition to the benefit working at all.
The Guide is equally clear about who is responsible. Whether a state uses managed care, fee-for-service, or some combination, “states retain ultimate responsibility for ensuring that all EPSDT-eligible children in the state have access to the full scope of coverage and services.” Because most children in Medicaid are enrolled in managed care, the Guide stresses that EPSDT responsibilities should be spelled out clearly in managed care contracts, that delegation to a plan does not relieve the state of accountability to the child, and that a managed care organization (MCO) may not apply a medical-necessity standard that is more restrictive than the state’s—including, importantly, an adult-oriented standard ill-suited to children. The state remains on the hook for unreasonable denials or barriers created by the plans it contracts with.
What EPSDT Covers: Screening, Diagnosis, and Treatment Across the Domains of Child Health
The Guide reaffirms that EPSDT sets out expectations for physical, mental, developmental, vision, hearing, and dental care, including screening, diagnostic, and treatment services in each category. The anchor for the benefit remains the comprehensive well-child visit (often called an EPSDT screening visit) delivered on a recommended schedule such as Bright Futures, which is used in a large majority of states. States must provide or arrange these “periodic” screenings and must also cover “interperiodic” screening on an as-needed basis whenever a problem is suspected by a parent, a teacher, or anyone else who comes into contact with the child.
Consistent with longstanding policy, the Guide reiterates a “no wrong door” principle for the well-child screening visit: a screen need not be performed by a Medicaid provider in order to trigger EPSDT coverage for follow-up diagnostic and treatment services. A school nurse, a nurse home visitor, or a clinical social worker might conduct a screen that triggers follow-up care, regardless of whether that screening provider is an enrolled Medicaid provider. As the Guide puts it, “any visit or contact with a qualified medical professional is sufficient to satisfy EPSDT’s screening requirement.”
Medical Necessity: Individualized and Free of Hard Limits
Federal law sets the parameters for medical necessity under EPSDT, and states make decisions based on the individual child’s condition and the recommendations of the child’s providers. For EPSDT, states must cover the full range of services described in Section 1905(a) of the Social Security Act when medically necessary, regardless of whether those services are covered for adults. As the Guide frames it, services within the Section 1905(a) scope must be provided to an EPSDT-eligible child if they are necessary to “correct or ameliorate” the individual child’s physical or mental condition, an inherently individualized standard that must account for the child’s long-term needs, not just the immediate situation. States’ approach to medical necessity “may not contradict or be more restrictive than the federal statutory EPSDT requirement,” and flat or arbitrary limits—rigid visit or hour caps, budgetary caps, or fixed cutoffs—cannot substitute for an individualized determination. This individualized standard centers professional expertise and family experience on the child’s condition in care decisions, rather than limits set by politicians or bureaucrats.
The Guide breaks some new ground here, too: it cautions that where a state or its contractors use software to help streamline coverage decisions, that software must be consistent with the same “correct or ameliorate” standard—a notable guardrail as the use of algorithmic tools and algorithmic tools and automated AI systems spread through utilization management.
The Guide is also explicit on a point that recurs in coverage disputes: EPSDT covers services that correct, ameliorate, and maintain. States must cover Section 1905(a) services not only to cure or improve a condition, but also to maintain a child’s functioning or to prevent a condition from worsening, even when the service will not make the child “better.” That directly undercuts the so-called “plateau” rationale that some payers have used to terminate ongoing therapy or treatment once a child stops showing measurable progress. If the treatment keeps a child from regressing, it is covered.
A Broader Workforce and Mental Health Without Waiting for a Label
Where the 2014 Guide focused largely on traditional clinical settings and providers, the 2026 Guide gives more attention to expanding the children’s health care workforce. It notes “States may expand the range of existing providers of Medicaid covered services by establishing qualifications for paraprofessional provider types, such as youth and family peer supports and other types of non-licensed providers.” This builds directly on the workforce strategies in the 2024 guidance and the recent behavioral health toolkit, and it gives states a clearer path to draw on community-based roles to meet children’s needs.
On mental health, the Guide carries forward a theme we flagged when the behavioral health toolkit was released: states can allow behavioral health services to begin before a formal diagnosis is established. Given long waitlists for specialty evaluation, a “diagnosis-free” approach lets children start getting help while a clinical label may be pending, and it creates more opportunity, especially for the youngest children, to act early, when intervention does the most good.
Dental, Schools, and Home- and Community-Based Settings
Oral health and dental care remain core. The Guide affirms that states must cover oral screenings and should adopt a periodicity schedule such as the American Academy of Pediatric Dentistry’s. It continues to frame dental referral as required “at as early an age as necessary” (even as professionals recommend a first dental visit by age one), and it confirms coverage of dental care for relief of pain, restoration of teeth, and maintenance of dental health; emergency, preventive, and therapeutic services for dental disease; and medically necessary (non-cosmetic) orthodontia. It also discusses the roles of other dental professionals working under a dentist’s supervision and of primary care providers.
Unlocking School-Based Care. The Guide reiterates that services provided in schools can play an important role in the health care of adolescents and children and cites CMS’s 2023 comprehensive guide to Medicaid school-based services that encourages states and schools to expand school-based care and clarifies that schools may deliver and bill for covered services—including EPSDT services—for all eligible students, not only those with IEPs.
Children on HCBS waiver waiting lists keep their full EPSDT entitlement. Some states have wrongly denied EPSDT services to children who are waitlisted for, or enrolled in, home and community-based services (HCBS). The Guide is unambiguous: children “who have been determined eligible for Medicaid and are on a waiting list for an HCBS waiver program are entitled to EPSDT and to all medically necessary services” covered under Section 1905(a). While waiver services themselves may be limited, states may not limit the amount, duration, or scope of EPSDT-covered Section 1905(a) services for a child because that child is on a waiver waiting list or enrolled in a waiver.
Where the Guide Falls Short
For all it does well, the Guide leaves real gaps. Most notably, it gives short shrift to developmental services. The Guide treats child development largely through screening—developmental assessments at the well-child visit, and referrals to early-intervention or special-education programs when a concern surfaces—but, unlike the dedicated discussions it gives oral health, vision and hearing, mental health, and personal care, it offers little on developmental services or early intervention as treatment. That gap matters for children with developmental delays and disabilities, and for the interface between EPSDT and early intervention under Part C of IDEA.
The Guide’s treatment of interagency coordination is also thin. It acknowledges the federal requirement that state Medicaid agencies collaborate with their Title V Maternal and Child Health agencies, and it gives examples of qualifying cooperation, but it omits two elements that are often central to these interagency agreements: data sharing related to child health, and payment to providers for clinical services delivered through Title V agencies (for example, care coordination for children with special health care needs, or well-child clinics in local health departments). The section is also silent on the longstanding relationship between EPSDT and Head Start.
Oversight and Program Integrity
A final point deserves emphasis. The 2026 Guide devotes a full section to state and federal quality reporting and monitoring of EPSDT, reinforcing that states cannot meet their obligations without processes to oversee, verify, and enforce them, and that CMS has its own role to play, including through the Form CMS-416 and the Child Core Set. That emphasis is no accident: the Bipartisan Safer Communities Act directed CMS not only to issue EPSDT guidance but to review state implementation and strengthen oversight. Robust implementation—and the federal oversight that ensures it—is itself a powerful tool for program integrity. It is how we make sure that the substantial federal and state investment in children’s coverage actually reaches the children the benefit is meant to serve. At a moment when so much federal attention is trained on program integrity, it is worth remembering that ensuring children actually receive the care they are legally owed is an important program integrity question too.
Looking Ahead
Taken together, the 2026 Guide is a useful consolidation and, in several respects, a meaningful reinforcement of the children’s benefit. It arrives, as the behavioral health toolkit did, at a hard moment for states. With federal Medicaid cuts under H.R. 1 straining state budgets, it is more important than ever to remember that EPSDT requirements are obligations, not aspirations, and that they apply regardless of the delivery system a state chooses or the fiscal pressure it faces. Recent federal court settlements requiring states to build out intensive home- and community-based services for children make the same point. Advocates, plans, and state staff should put the refreshed Guide to work: to inform families about what their children are owed, to write and enforce MCO contracts, to remain committed to preventive well-child screening visits, and to hold the line on medically necessary care for kids.
