HEDIS measurement year 2023 documentation for Lead Screening in Children (LSC)


Measure description: The percentage of children 2 years of age who had one or more capillary or venous lead blood test for lead poisoning by their second birthday.


In provider medical records, we look for the following:

  • Immunization records from birth (Department of Health immunization records are acceptable).
  • If available, newborn inpatient records documenting hepatitis B.
  • For immunizations not recorded on the immunization record, provide progress notes for:
    • Immunizations administered.
    • Patient’s history of disease (chickenpox, hep A, hep B, measles, mumps, rubella).
  • Lead testing results and date (capillary or venous) on or before the second birthday.
  • Evidence of hospice services in 2023.
  • Evidence patient expired in 2023.


Helpful hints:

  • Childhood immunizations and lead blood tests must be completed by child’s second birthday.
  • Assess immunization needs at every clinical encounter and, when indicated, immunize.
  • Ensure immunization records include all vaccines that were ever given including hospitals, health departments, and all former providers, including refusals and contraindications.
  • FluMist (LAIV) vaccination (only approved for ages 2 to 49) may be used for the second vaccination; however, it must be given on the child’s second birthday to be compliant.
