This is a very challenging question to answer. In health care we have a set of differences of opinion about what is enough. There is the perhaps strictly clinical opinion, based on the physician. There is the perhaps strictly patient perspective, in terms of “here's what I want”, and there is the strictly “I'm the payer” opinion.
I'm sorry. I'm not answering your question, but I suspect that if you were to ask the three different people, you would get three different answers.
