Treatment costs, insurance, deductible accumulators

How do you guys cover the costs of drugs like promacta? Nplate? I've been reading up on deductible accumulators (universal co-pay program payments don't count towards your deductible or out-of-pocket-max) and I'm scared I won't be able to afford treatment when I get an insurance plan (I'm on medicaid now). Do insurance plans on the ACA marketplace have deductible accumulator policies?

How much do you spend per year on prescriptions for this condition. 

All about insurance with these drugs I guess. Before thinking of promacta or Nplate, you might want to take a TPO test, from what I've read here... If you have normal TPO, you don't need Promacta or Nplate. I believe then it would be Retuximab or natural like Papaya leaf extract. Not a doctor, but I play one for myself. So far, I'm avoiding any big drug questions, although insurance did have to endure the initial hospital stay unfortunately. Of course, I was blindsided with an ultra-low platelet count before I could research. Now, the only insurance costs are the constant blood tests.
