A family friend uses PetPlan. They have absolutely loved it and say it's worth every penny. Their dog got necrotizing pancreatitis, was treated (41 straight days in ICU!) and survived. He's diabetic now and needs insulin because of that, has had phacos and new lenses on both eyes because of diabetic cataracts, needs prescription low fat food, and usually has a yearly pancreatitis flare up that requires hospitalization. They have had over $30,000 in vet bills for this dog in the past two years, but PetPlan covers 80% of everything since this is all related to that one event of necrotizing pancreatitis. They are always reimbursed within 10 days after the school sends the paperwork in. Her monthly payment is like $30. As far as I know there isn't an age cutoff, just a higher monthly cost for older pets. Once I graduate and have more disposable income, I plan on getting PetPlan for my own dog.
