<prompt> Human: Hi, I have two insurance plans: medi-cal medicare in california and one given to me by my university. Last october I had to have surgery, and I gave the hospital my university insurance information. Months later, I paid off a small amount, then was told by a hospital rep that I could apply for medi-cal to cover my expenses.I told him that I already had medi-cal, he took my information, and said the bill was all taken care of. Now, Im wondering if I could possibly be refunded the small amount that I had originally paid before I let medi-cal pay the rest. I could really use that money as the school year is starting soon and I would rather not take out loans to pay for school. Thanks for any help.  <response>: Just to clarify a small point - Med-cal is Californias Medicaid.Medicare is a similar program for the elderly and those with certain specific diseases.Medicaid is state by state; Medicare is federal.
