The same as any other billable code, the patient is responsible for deductibles, co-payments, and remainder amounts according to the patient’s insurance agreement. Unfortunately 99490 is not exempt from cost-sharing rules, so Medicare Part B patients with no secondary coverage will be responsible for approximately $8/month. The intent of the code is to reduce costs for all parties, including the patient. Better coordination means fewer visits, which in turn reduces the patient’s overall out-of-pocket expenses.
