Common questions

How many Medicare-certified home health agencies are in Ontario, California?

Does Medicare cover home health care?

Medicare.gov describes home health as a wide range of health care services that a patient can get at home for an illness or injury. The patient must need part-time or intermittent skilled services and be “homebound.” A doctor or other health care provider (like a nurse practitioner) must see the patient in person, confirm the need for home health care and order it, and a Medicare-certified home health agency must provide it. The patient pays nothing for covered home health services (Medicare.gov notes that other costs may apply).

What doesn't Medicare home health cover?

Medicare doesn't pay for 24-hour-a-day care at home, home meal delivery, homemaker services unrelated to the care plan, or custodial or personal care when that is the only care needed, according to Medicare.gov.

How this page is built

The first list uses the City/Town and State in the CMS home health agency file (the agency's office address). The second list uses CMS's home health ZIP code file, which lists for each ZIP code the agencies that CMS reports served at least one patient in that ZIP code during its data collection period. CMS publishes no table that ties ZIP codes to cities, so the ZIP codes for Ontario are only those that appear in CMS-listed addresses in Ontario, CA of nursing homes, hospices and home health agencies. A ZIP code can also cover places outside Ontario, and a part of Ontario can have a ZIP code that no CMS address uses.
