The Child Health and Disability Prevention (CHDP) provides complete health assessments for the early detection and prevention of disease and disabilities for low-income children and youth. A health assessment consists of a health history, physical examination, developmental assessment, nutritional assessment, dental assessment, vision and hearing tests, a tuberculin test, laboratory tests, immunizations, health education/anticipatory guidance, and referral for any needed diagnosis and treatment.  

The CHDP program oversees the screening and follow-up components of the federally mandated Early and Periodic Screening, Diagnosis, and Treatment (EPSDT) program for Medi-Cal eligible children and youth.

In July 2003, the CHDP program began the using the “CHDP Gateway,” ​an automated pre-enrollment process for non Medi-Cal, uninsured children.  The CHDP Gateway , serves as the entry point for these children to enroll in ongoing health care coverage through Medi-Cal. The CHDP Gateway is based on federal law found in Titles XIX and XXI of the Social Security Act that allows states to establish presumptive eligibility programs for children/youth.
