This study has several limitations. First, this study relies on claims data which may contain erroneous codes . Secondly, the location of the abortion provider may be inaccurate. While we aimed to ensure that we captured the location of abortion provision by use of billing address rather than other addresses, it is possible that the facility used a different administrative address than the location where the abortions occurred, reducing the accuracy of our distance calculation. Third, it is likely that women with Medi-Cal coverage paid out of pocket for abortion care due to difficulty getting Medi-Cal payment, to protect their privacy, or to obtain their abortion from a provider who did not accept Medi-Cal (for reasons of geographic proximity, trust, or a lack of knowledge about Medi-Cal abortion coverage), leading us to have underestimated the total number of abortions in this population. Furthermore, the study did not include women on other Medi-Cal plans including Presumptive Eligibility for Pregnant Women and Medi-Cal Access Program Medi-Cal plans, which are likely composed of younger women living in more urban areas and who would travel shorter distances to a provider. Finally, our data included only reimbursed claims, not all billed claims. It is possible that providers billed for abortions which were not reimbursed due to provider or Medi-Cal error. This could result in underestimation of both abortions and Medi-Cal FFS providers.
