Praying Medically v. Praying Financially

If made to choose between praying for someone to successfully come through a difficult medical procedure or for the bill to be paid, which would a logical person choose? It seems it should be the bill because the patient's outcome still depends on the skill and knowledge of the trained medical team, which remains the same. Unless a random person off the street is handed a scalpel and told to operate, even a believer would be best served by praying financially.
