I have a doctor that gives a general to a patient for a modified radical mastectomy and does a paravertebral block on them for post op pain. I have heard of one or the other and the reasons why, but I am having trouble with medicare paying for them because they have a limited diagnosis list for this type of procedure. Do you think I can fight Medicare on these with my records to back it up? Or, should I not waste my time with it? My doctor is insisting on it and I have explained to him that it is not medically necessary to do these blocks. However, there are benefits to doing them. On the other hand, there are also negatives. Suggestions?????
