Medicaid EPSDT: what CMS says about therapy for children under 21
Early and Periodic Screening, Diagnostic, and Treatment (EPSDT) is Medicaid’s benefit for children under age 21. Medicaid.gov says states must furnish all Section 1905(a) Medicaid coverable, appropriate, and medically necessary services needed to correct and ameliorate health conditions. CMS’s EPSDT guide for states names physical, speech/language, and occupational therapies in that scope, and says PT and OT are covered when they have an ameliorative, maintenance purpose. States decide medical necessity case by case; this page does not describe any state’s coverage.

What EPSDT is
Medicaid.gov states: “The Early and Periodic Screening, Diagnostic and Treatment (EPSDT) benefit provides comprehensive and preventive health care services for children under age 21 who are enrolled in Medicaid.” It states: “States are required to furnish all 1905(a) Medicaid coverable, appropriate, and medically necessary services needed to correct and ameliorate health conditions, based on certain federal guidelines.”
Under “Other Necessary Health Care Services”, it states: “States are required to provide any additional 1905(a) services that are coverable under the Federal Medicaid program and found to be medically necessary to treat, correct, or reduce illnesses and conditions discovered regardless of whether the service is covered in a state's Medicaid plan.” And: “It is the responsibility of states to determine medical necessity on a case-by-case basis.” The Medicaid.gov page itself does not name OT, PT, or speech-language therapy; the CMS documents below do.
Therapies, in CMS’s guide
The May 2026 guide states: “States must ensure coverage of all medically necessary services that are included within the categories of mandatory and optional services listed in Section 1905(a) of the Act, regardless of whether such services are covered under the state plan for adults. This includes physician, nurse practitioner, and hospital services; physical, speech/language, and occupational therapies;” followed by other categories.
On community-based care, it says the EPSDT requirements include coverage of listed Section 1905(a) services “when medically necessary to correct or ameliorate a child’s condition:” among them “physical, occupational, and speech-language therapy.”
On maintenance, the guide states: “In addition to services that can ‘correct’ a condition, services that can ‘ameliorate’ a condition (i.e., make a condition more tolerable) must be covered under EPSDT.” SHO # 24-005 states: “Thus, services such as physical and occupational therapy, for example, are covered when they have an ameliorative, maintenance purpose.”
Limits on therapy visits
The guide states: “Flat, fixed, hard, or arbitrary limits (e.g., budget or monetary caps, standard deviations from the norm, or hourly maximums) are not consistent with the EPSDT requirements and therefore may not be applied to the coverage of Section 1905(a) services for EPSDT-eligible children.” It gives a physical therapy example: “although a state may include in its state plan a limit on the number of physical therapy visits per year for individuals age 21 and older, such a hard limit could not be applied to EPSDT-eligible children.” It continues: “A state could impose a ‘soft’ limit on the number of physical therapy visits, but if it were to be determined through review of an individual child’s case that additional physical therapy services were medically necessary to correct or ameliorate the child’s condition, those services would have to be covered.”
Where EPSDT meets schools and early intervention
EPSDT is a Medicaid benefit; IDEA services in schools and early intervention are separate programs with their own rules. Those are on IEPs and IFSPs, early intervention, working in schools, and Section 504 plans. This page does not say how any state bills Medicaid for school-based services.
What this page does not do
It does not describe any state’s Medicaid plan, prior authorization rules, visit limits, or payment, and it does not decide whether a service is medically necessary for any child. It is not legal, billing, or compliance advice. Confirm current rules with the agency that publishes them, your employer, and your state board.
