Early and Periodic Screening, Diagnostic, and Treatment

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. EPSDT is key to ensuring that children and adolescents receive appropriate preventive, dental, mental health, and developmental, and specialty services.

  • Early: Assessing and identifying problems early
  • Periodic: Checking children's health at periodic, age-appropriate intervals
  • Screening: Providing physical, mental, developmental, dental, hearing, vision, and other screening tests to detect potential problems
  • Diagnostic: Performing diagnostic tests to follow up when a risk is identified, and
  • Treatment: Control, correct or reduce health problems found.

EPSDT Services

States are required to provide comprehensive services and furnish all Medicaid coverable, appropriate, and medically necessary services needed to correct and ameliorate health conditions, based on certain federal guidelines. EPSDT is made up of the following screening, diagnostic, and treatment services:

Screening Services

  • Comprehensive health and developmental history
  • Comprehensive unclothed physical exam
  • Appropriate immunizations (according to the Advisory Committee on Immunization Practices)
  • Laboratory tests (including lead toxicity screening
  • Health Education (anticipatory guidance including child development, healthy lifestyles, and accident and disease prevention)

Vision Services

At a minimum, diagnosis and treatment for defects in vision, including eyeglasses. Vision services must be provided according to a distinct periodicity schedule developed by the state and at other intervals as medically necessary. For additional information visit the Vision and Hearing Screening Services for Children & Adolescents page.

Dental Services

At a minimum, dental services include relief of pain and infections, restoration of teeth, and maintenance of dental health. Dental services may not be limited to emergency services. Each state is required to develop a dental periodicity schedule in consultation with recognized dental organizations involved in child health.

Hearing Services

At a minimum, hearing services include diagnosis and treatment for defects in hearing, including hearing aids. For additional information visit the Vision and Hearing Screening Services for Children & Adolescents page.

Other Necessary Health Care Services

States are required to provide any additional health care 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. It is the responsibility of states to determine medical necessity on a case-by-case basis.

Diagnostic Services

When a screening examination indicates the need for further evaluation of an individual's health, diagnostic services must be provided. Necessary referrals should be made without delay and there should be follow-up to ensure the enrollee receives a complete diagnostic evaluation. States should develop quality assurance procedures to assure that comprehensive care is provided.


Necessary health care services must be made available for treatment of all physical and mental illnesses or conditions discovered by any screening and diagnostic procedures.

State Program Guidelines

State Medicaid agencies are required to:

  • Inform all Medicaid-eligible individuals under age 21 that EPSDT services are available and of the need for age-appropriate immunizations;
  • Provide or arrange for the provision of screening services for all children;
  • Arrange (directly or through referral) for corrective treatment as determined by child health screenings; and  
  • Report EPSDT performance information annually via Form CMS-416.

Periodicity Schedule

Periodicity schedules for periodic screening, vision, and hearing services must be provided at intervals that meet reasonable standards of medical practice. States must consult with recognized medical organizations involved in child health care in developing their schedules. Alternatively, states may elect to use a nationally recognized pediatric periodicity schedule (i.e., Bright Futures ). A separate dental periodicity schedule is also required.

Developmental and Behavioral Screening

Periodic developmental and behavioral screening during early childhood is essential to identify possible delays in growth and development, when steps to address deficits can be most effective. These screenings are required for children enrolled in Medicaid, and are also covered for children enrolled in CHIP. This CMS Fact Sheet describes CMS resources to support states in ensuring enrolled children receive these screenings. Birth to 5: Watch Me Thrive!, a joint effort between the Department of Health and Human Services and the Department of Education, provides additional resources to support states, providers and communities to increase developmental and behavioral screening of young children.

Lead Screening

While substantial environmental improvements have been made to reduce exposure to lead, there are still over four million children estimated to reside in housing where they are exposed to lead. Learn more about Medicaid lead screening policy.

EPSDT Strategy Guides to Support States with the Medicaid Benefit for Children and Adolescents

In 1967, Congress introduced the Medicaid benefit for children and adolescents, known as Early and Periodic Screening, Diagnostic and Treatment (EPSDT). The goal of this benefit is to ensure that children under the age of 21 who are enrolled in Medicaid receive age-appropriate screening, preventive services, and treatment services that are medically necessary to correct or ameliorate any identified conditions – the right care to the right child at the right time in the right setting. This broad scope supports a comprehensive, high-quality health benefit. States share responsibility for implementing the EPSDT benefit with the Centers for Medicare & Medicaid Services. (For more information, see "What You Need to Know about EPSDT.)

As one outcome of a National EPSDT Improvement Workgroup, the Center for Medicaid & CHIP Services is developing a set of strategy guides, each on a specific topic, to support states and their partners as they implement the EPSDT benefit.  Each strategy guide identifies specific, doable approaches to improve access, utilization and quality of care for children and adolescents enrolled in Medicaid. Examples of state successes are offered along with web-based links to resources, tools and more in-depth.

The first four guides in the series are:

Annual EPSDT Reporting Using the Form CMS-416

The Form CMS-416 is used by CMS to collect basic information on State Medicaid and CHIP programs to assess the effectiveness of EPSDT services.

Annually, states must provide CMS with the following information:

  1. Number of children provided child health screening service
  2. Number of children referred for corrective treatment
  3. Number of children receiving dental services
  4. State's results in attaining goals set under section 1905(r) of the Social Security Act.

Form CMS-416 and instructions

To report data prior to FFY 2020 (Oct. 1, 2019 – Sept. 30, 2020) or to request a 508-version of the form, please email EPSDT@cms.hhs.gov.

Additional resources for reporting include:

National EPSDT Improvement Workgroup

In December 2010, CMS convened a National EPSDT Improvement Workgroup that included state representatives, children's health providers, consumer representatives, and other experts in the areas of maternal and child health, Medicaid, and data analysis. The members of the group will help CMS identify the most critical areas for improvement of EPSDT. The group, which meets periodically throughout the year, will also discuss steps that the federal government might undertake in partnership with states and others to both increase the number of children accessing services, and improve the quality of the data reporting that enables a better understanding how effective HHS is putting EPSDT to work for children.
