User-friendly tool helps identify hospitals and health systems committed to providing high-quality maternity care

Today, the Centers for Medicare & Medicaid Services (CMS) will begin displaying the ‘Birthing-Friendly’ designation icon on CMS’s Care Compare online tool.

But state-run exchanges (there are 18 of them as of 2022) can set their own rules for qualifying events and special enrollment periods. Some of them do allow a special enrollment period triggered by pregnancy. This gives a pregnant person access to health coverage during the pregnancy, rather than having to wait until the baby is born to obtain coverage. As of 2022, pregnancy is a qualifying event in the following state-run exchanges:
