Best Practice and Measure Tips

  • Advise patient on the importance of completing each vaccine series.
    • Provide handouts.
    • Educate members on vaccination and side effects.
    • Review immunization records at each visits and catch up with any missing immunizations.
  • Office improvement opportunity
    • Place guidelines to schedule visits within the CDC guidelines timeframe. Reference the CDC Immunization Vaccine Schedule.
    • Contact member to re-schedule any missed appointment for their vaccination.
    • Use your electronic medical record (EMR) to set flags with immunization gap timeframes.
    • Ensure that members’ medical records include immunization history from all sources.
    • Train medical staff to answer questions about vaccinations, administer vaccinations, and document vaccinations.
    • Use measure codes and exclusion code listed below when submitting claims to make member compliant by administrative data.
    • DOCUMENT ANY PATIENT REFUSAL FOR IMMUNIZATIONS. This does not exclude member from measure.
    • The below count towards compliance for the vaccine. Document with event date:
      • Anaphylaxis due to the vaccine.
      • Evidence of the antigen or combination vaccine.
      • Documented history of the illness.

Acceptable documentation:

  • A certificate of immunization prepared by an authorized health care provider or agency including the specific dates and types of immunizations administered.
  • A note indicating the name of the specific antigen and immunization date.

Not Acceptable:

  • A note the "member is up to date" with all immunizations but does not list the dates and names of all immunizations.
