Vaccine Administration
Any OHP provider administering children’s COVID-19 immunizations; or
Any OHP-enrolled pharmacies providing children’s flu immunizations, for the duration of the
COVID-19 Public Health Emergency.
Pharmacies will need to enroll in the VFC program to provide any other children’s immunizations.
“No Wrong Door” policy for providers serving FFS and CCO members
OHA has implemented a “No Wrong Door” policy to ensure access for both FFS and CCO members
who present themselves at any OHP-enrolled COVID-19 vaccine provider location to receive a
COVID-19 vaccination.
Providers contracted with the member’s CCO should bill the CCO.
Providers not contracted with the CCO should bill OHA. Be sure to also contact your local
CCO(s) to explore direct contracting options. Find contact information at bit.ly/cco-contacts.
Counseling
Counseling patients about COVID-19 vaccine, including advising them about the risks from getting
and not getting vaccinated, is covered by OHP.
Reimbursement for up to 20 minutes of counseling, when provided at the same visit as a
vaccine administration, is included under the vaccine administration codes.
Reimbursement is available for time spent counseling at a vaccine administration visit in
excess of 20 minutes. See billing details below.
Reimbursement for counseling that does not occur at a vaccination visit is available under
covered Evaluation and Management codes.
For additional/booster doses:
Instruct members to get second dose vaccines on the date specified by the manufacturer’s product
labeling for products that require a second dose.
For guidance about additional doses for the immunocompromised and booster doses, please refer to
OHA’s COVID-19 immunization protocol. This document contains current guidance for COVID-19
immunization providers, including the COVID-19 vaccine schedule, recommendations for use,
contraindications, warnings and precautions, and other considerations.
Billing
Only bill for the vaccine administration, not the serum.
Use diagnosis code Z23 (Encounter for immunization).
Dentists billing OHA for vaccine administration are subject to OAR 410-123-1262.
Professional claim format

administration using the professional claim format, as described below.
To bill for counseling provided during the administration visit that exceeds 20 minutes, add
modifier 22.
