I need a hip replacement surgery co pay help. I have MS and am on disability. Does anyone know if there is any assistance out there?

Americans "on disability" normally have Medicaid without copays for things like hip replacement, provided a doctor says it's medically necessary, not elective. Maybe it's different in your state. If you're not on Medicaid for some reason, is it possible for you to apply for it? Or have they told you that your income or assets are too high?

If Medicaid can't help, and you still would have a high copay you can't afford... you might try contacting the Multiple Sclerosis Association of America: https://mymsaa.org/

(Contact info at the bottom of the page.) They do provide financial assistance for specific needs in some cases, or if they can't help directly, they may be able to put you in touch with someone who can.

Medicaid?
