can medical bills be filed under bankruptcy

I'm not sure what you mean by "filed under".   All debts, and all assets, must be listed in any bankruptcy petition.  A failure to do so is grounds for denial of your discharge and possible criminal sanctions. If you're asking whether or not medical bills are dischargeable in bankruptcy, the answer is usually, but it depends on exactly how the debts were incurred.  Certain debts are excepted from discharge such as debts incurred without the intent to repay.    Mark Markus has been practicing exclusively bankruptcy law in California since 1991.  He is a Certified Specialist in Bankruptcy Law by the State Bar of California Board of Legal Specialization,  AV-Rated by martindale.com, and A+ rated by the Better Business Bureau.
