1.24.2014 Proportion of Days Covered by Medications (PDC) The Oral Diabetes Tab includes the NDC code 47463051060, which may be incorrectly assigned to a GCN. This NDC (47463051060—metformin) is assigned to GCN 71160. However, for other NDCs with the same generic drug name (metformin), route and GPI are assigned to GCN 89863. Which GCN is correct?

The NDC code 47463051060 (Metformin HCl Tab SR 24HR 500 MG) is incorrectly assigned to GCN 71160. The correct GCN is 89863.

This particular NDC was recycled to the medication metformin and therefore should have a GCN of 89863, rather than the previous GCN linked to the obsolete NDC.
