Office Visits
Medicare reimburses office visits using a five-point scale, with five being the most intensive and costly. The chart below shows what percentage of this provider’s office visits were reimbursed at each level. A higher than average proportion of costly visits is not necessarily an indication of a problem, but it may be worth asking about.
