Memorial Hermann Memorial City payment plans

i have a surgery coming up at the end of the month and they just called me yesterday and told me the total for my procedure. i’m looking at several thousand dollars out of pocket. she told me i could pay a portion of it as a “deposit” and then after my surgery i could set up a payment arrangement for the rest. does anyone have experience with their payment plans? it’s already a bit rough out here as im pretty much living paycheck to paycheck, but ive already had to reschedule my surgery twice due to financial reasons and miscommunication on my surgeons end. i really don’t want to wait any longer than i already have but i don’t want to screw my future self over either. thanks in advance!
