Rynhoop,
While I have not had a cystectomy (although I am BC survivor), I have had other major surgeries (bypass and torn ligaments with re-hab). My insurance allowed an adequate amount of re-hab as outpatient and I would look into extra coverage for home health if your insurance allows with nurses checking up to help you and your Dad. I am assuming some that have had your surgery will chime in on actual experience plus I have found the discharging nurses I have had were really good on what to expect. You are thinking ahead and will do fine!
