Child Health and Disability Prevention Program (CHDP)

The Child Health and Disability Prevention Program (CHDP) covers preventive
care for children under age 20. CHDP serves children with family incomes
below 200% of the federal poverty level. (For example, that’s $2,504 a month
for a family of three.) CHDP pays for regular check-ups and shots. It covers
many important tests, like vision and hearing tests. It does not pay for
hospital care.
