Last I heard, Peg was about $1,200 per month. Copays vary widely by insurance co. Call your pharmacy. They can tell you what Peg would cost you if yr doc prescribed it based on yr coverage. I have rec'd very good care from my hematologist at our regional medical center 30 minutes away. I could get a referral to the big university center's MPN experts if I needed to, but I have been well controlled, no clots, and have had the standard bone marrow and genetic tests. So I don't think a consult with an MPN specialist is crucial. But if you have GP who is trying to wing it or an internist who is not doing standard testing and monitoring, I would ask for a consult. Good luck!
