Medicare

Hi my mom is a 62 y.o F diagnosed with Parkinson’s about 2-3 years ago. We just applied for Medicare via the disability route and just got approved. Her current meds are GoCovri and Crexont as far as PD meds go. What insurance company/plan do your loved ones have? I’m thinking of enrolling her in Part A, B, D, and possibly G? Still researching on all the parts.
