I had a procedure done the first week of January this year. (everything's fine.) The bills have been dribbling in. I just got one for $225. Six months after the test, I get a bill. I think this is the fourth one. Each service provider is individually represented. Even though each bill comes from the same parent entity. Although, I still haven't heard from the valet. (I kid, I kid. I paid him at the time of service delivery). If Sutter is having cash flow problems I have some suggestions. Oh, and after waiting six months to bill me, I have 10 days to pay.
