I just got off the phone with United HealthCare and they are covering the CGMS for me under DME. I am ecstatic!
DME == "Durable Medical Equipment' which sometimes separate deductibles and annual limits. Congrats Dad, and welcome to the club!
Sorry about that. The answer is "sort of." I am responsible for $299 upfront because my pump is less than 3 years old. Everything else for the CGMS I pay 10% after the $500 deductible is met...but only up to a maximum of $2500 under the DME plan. Was that easy enough? Me either.
