Childhood Blood Lead Level Screening Requirements

The Department of Health Care Services (DHCS) requires that all providers who conduct periodic health assessments on Medi-Cal children provide the following:

  • Verbal or written anticipatory guidance to child's legal parent or guardian of the harmful effects of lead exposure for children starting at ages six months to 72 months (6 years). At a minimum, the information should include that:
    • Children can be harmed by lead exposure from old or chipping lead-based paint and dust.
    • Children that begin to crawl until 72 months of age, are particularly at risk.
  • Blood lead level testing (finger stick or venous blood draw) on children:
    • At 12 months and 24 months of age.
    • If child between ages 12-24 months have no record of lead testing.
    • If child between ages 24-72 months is missing a lead test at 24 months or after.
    • When requested by child's parent or guardian.
    • When provider conducting Periodic Health Assessment (PHA) for child 12-72 months is aware of increased risk of lead exposure/poisoning due to changes in child's circumstances.

Providers must follow the California Department of Public Health Guidelines (PDF) for interpreting blood lead levels and follow-up activities for elevated blood lead levels.

  • Screening for elevated blood levels can be conducted by finger stick test or via venous blood draw.
  • Confirming or retesting of blood lead levels should be conducted through the venous blood test.

    Encounter for screening for disorder due to exposure to contaminants ICD-10 Z13.88
  • Providers and labs must report all lead test results to the Childhood Lead Poisoning Prevention Branch (CLPPB). Contact

Exceptions to providing a lead screening

Providers are not required to perform lead screening if:

  • Legal parent/guardian refuses the lead screening and signs a voluntary refusal statement
  • In provider's professional judgement, lead testing poses greater risk for child than lead poisoning

Providers must document reasons for not providing the lead screening or not obtaining the voluntary refusal statement in the child's medical record.
