For Black patients
If you are a Black patient being seen at ADVENTIST HEALTH SONORA in Sonora, California, a few concrete steps:
- Bring an advocate. National data from CDC's Black maternal mortality review show the single biggest reduction in missed-diagnosis rates comes from a second set of ears in the room — a partner, a doula, a family member. Ask in advance that they be credentialed as a visitor; the hospital cannot turn away a designated support person.
- If you need ongoing primary care, our California provider directory filters to physicians who accept Medicaid and speak Spanish / Haitian Creole / ASL where relevant. Filter to your insurance first.
- If the hospital doesn't take your coverage, the closest Federally Qualified Health Center is listed under our FQHCs in this area. FQHCs serve every patient on a sliding-fee scale regardless of insurance status.
- For help paying for care, the state Medicaid navigator at /medicaid/california/ explains eligibility, documents, and how to apply (same-day presumptive eligibility for pregnancy).
- If you are treated dismissively or your pain is ignored, every Medicare-certified hospital is required by CMS Conditions of Participation (42 CFR 482.13) to have a grievance procedure; file in writing and request the CMS regional office contact if the hospital ombuds does not respond within seven days.
