Plot hole: It doesn't make much sense that Marie had to ask Walt and Skyler to pay Hank's medical bills. They both make good money! Hank is a DEA agent and she is some kind of medical professional. There is no reason in the world that this couple cannot afford this. Same thing with Walt.
Suggested correction: Their insurance doesn't cover the bills; without that, bills can stack up quickly. You need a lot higher salary than a DEA agent to cover it, even if he got as high as 120,000 USD a year. Marie can't work as she is taking care of her husband.
