For someone with a HIGH ProsTox test, suggestive of higher risk delayed urinary tract symptoms [15 vs 5%] the interval between sessions may be prolonged. Instead of 5 visits over two weeks (alternate days) maybe the 5 sessions can be provided over 5 weeks. The third party compensation may be the same regardless of time. I saw US$27K for SBRT and US$37K for IMRT. Moderate IMRT of 20 sessions was just as good 37 to 40. I know Medicare 'A' went to a DRG payment schedule for inpatient care. That is the institution prospective compensation. Physician visits are paid through Medicare 'B' and may still be a la carte fee for service?
