One Senior had an MRI recently at a diagnostic center (18653 Wedge Pkwy, Reno, NV 89511). The co-pay of $150 was paid for the MRI as agreed. Days later, the Senior received a bill for $128.97 from Radiological Consultants in Indianapolis. The name of the doctor was not revealed, nor was the reason for the charge. The Senior wrote to the billing company asking for an explanation. A few days later another bill was received with the same billing amount. Not knowing the name of the mysterious doctor, the Senior wrote to all of the doctors listed for the Radiological Consultants in Reno demanding an explanation and asked for the charges to be settled by arbitration. Again, no reply. On Oct 3, the Senior received a recorded phone call from the billing company stating if the Senior did not pay the bill, it would be turned over to a collection agency. The Senior has chosen to fight the collection agency. The charge by the unnamed doctor at the center was not needed because the Senior had his own Orthopedic Doctor to evaluate the MRI the charge of which was 500% lower in cost. Some Seniors would have paid the bill because many are vulnerable. Nevada must protect the 16,000 Washoe County Seniors on Medicare from hidden charges and services that they did not agree to. When the MRI diagnostic center accepted the co-pay and the Seniors insurance card, they made a legal contract. Only in the medical business can doctors charge for services the cost of which is not stated or even made known to a patient. This must stop. It can only be stopped by legislation. Full transparency is the solution.
