Description: HIV is still a big public health concern, but there are therapies available to prevent infection before and immediately after exposure. As legislatures and the USPSTF considers adding these therapies to the list of preventive care covered without cost share, actuaries will need to estimate the impact on their care cost. The presenters will share an actuarial tool kit to estimate the impact of covering PrEP and PEP for different populations. Examples are provided and discussion is welcome.
