How does an Indian Health Services (IHS) DMEPOS supplier enroll with the NPWest to obtain billing privileges?


Answer:
Section 630 of the Medicare Prescription Drug, Improvement and Modernization Act of 2003 (MMA) allowed IHS facilities to bill for other Part B services, which were not previously covered under Section 1848 of the Act, and expanded the scope of items and services for which payment would be made to IHS providers, suppliers, physicians and other practitioners. As indicated in the Centers for Medicare & Medicaid Services’ (CMS) Change Request 6583, Section 630 ended on December 31, 2009 however, Section 2902 of the Patient Protection and Affordable Care Act indefinitely extends Section 630 of the MMA.
