Under CMS 2370-F, if a state uses vaccine product codes to pay for vaccine administration, must it submit a new ACA 1202 state plan amendment (SPA) when those product codes change?

States that pay for vaccine administration using the vaccine product codes were required to include a crosswalk to their administration codes as part of their ACA 1202 state plan amendment (SPA). They will therefore be required to submit a new SPA to reflect any changes in those codes. If a state does not use vaccine product codes to pay for vaccine administration and therefore there is no crosswalk in their 1202 SPA, then no updates are necessary to reflect the code changes.
