Recovering Overpayments from Providers Who Share Tax Identification Numbers

Section 1866j(6) of the Social Security Act authorizes the Secretary to make any necessary adjustments to the payments of a provider of services or supplier who shares a TIN with a provider of services or supplier that has an outstanding Medicare overpayment. The Secretary of Health and Human Services is authorized to adjust the payments of such a provider of services or supplier regardless of whether it has been assigned a different billing number or NPI from that of the provider of services or supplier with the outstanding Medicare overpayment. In January 2016, CMS enhanced its financial accounting system to include a function that allows CMS to recover payments made to a provider of services or supplier that shares the same TIN with a provider of services or supplier that has an outstanding Medicare overpayment across multiple states within a Medicare Administrative Contractor (MAC) jurisdiction.
