Tip: Check with your MAC to make sure your physicians are entered properly. If you report a new patient code and your MAC rejects it, stating that the patient is already established at your practice, you could be facing a problem that began when you enrolled your physician in Medicare. Doctors who are assigned to the wrong specialties in Medicare's systems can create a host of billing problems down the line. That's the word from a June 27 NGS Medicare "Ask the Contractor" teleconference, in which a caller presented the following scenario: Her internal medicine physician saw a new patient and reported a code from the 99201-99205 series. However, the MAC denied the claim saying that it did not meet new patient qualifications since the practice's cardiologist had seen the patient in the past. "That should normally be a new patient visit as long as the doctors are of different specialties," said NGS's Jim Bavoso during the call. "But what we have come across more often than not is that the specialties of both members of the group are listed as the same, and that would cause this to bump. What we have found is that we have doctors that are cardiologists who may not have changed their specialty in the program." Tip: Practices Stuck in 'No-Pay Zone' Another caller presented a scenario in which she is being forced to write off vast sums of money due to primary vs. secondary payer issues. Scenario: Unfortunately, Bavoso told the caller, MACs are powerless to pay providers in this scenario. "You should really voice your concern to CMS to make this change," he said. "There's no change on the horizon for this issue that we can see at this point," but contractors' hands are tied until CMS formally changes the policy. Bavoso recommends that practices facing this issue should submit a written complaint to their local CMS offices. But, added NGS's medical director Lawrence Clark, MD, "It's absolutely essential that you verify the patient's coverage at the beginning. It's easy in the sense that with patients age 65 and up, you would assume they've applied for Social Security. But if you have anyone with any chronic disability [younger than that], that's your tipoff that you have to pay attention to, particularly those with behavioral disturbances, because they are not honestly giving you an answer because they can't give you a good one, so you have to go to their caretaker."
