Medical Bill Consolidation
There are definitely ways to retroactively consolidate medical bills -- there's an entire industry of companies offering debt consolidation (many of which are scummy/predatory, be careful! See https://www.consumer.ftc.gov/articles/0150-coping-debt and some decent articles at http://blog.readyforzero.com/are-there-legitimate-debt-consolidation-loans and http://blog.readyforzero.com/how-to-find-a-reputable-debt-consolidation-company). In general, what you are looking to do is take out a loan, possibly at a better interest rate than whatever you are being charged currently, and pay off the medical bills. If you are not paying interest on the medical bills and are just being allowed to spread out the payments, you are already golden and should just put up with the ups and downs. If you have any equity in a home, take out a home equity loan or line of credit, pay off your medical bills. Rates are still great right now. Even if you have no home equity to tap, if you have a steady job you might be able to get a nice small loan from a local bank or peer-to-peer lending site. Do your homework and only work with reputable companies, especially if doing things online.
