The April, 2018 Medicare Part D plan formulary data (or drug list updates) includes the addition of 737 new National Drug Codes (NDCs) to the Medicare Part D program.  These NDCs represent 486 different drugs, many with multiple strengths. There are so many new NDCs, that we have to split the list into 5 parts. This article will cover Medicare Part D drugs starting with the letters I through M. Here are links to A-C, D-H, I-M, N-P, and Q-Z.

Fifty-seven new NDC generic equivalents were added, including including IMATINIB MESYLATE [Gleevec®], IRBESARTAN [Avapro®], LANTHANUM CARB [Fosrenol®], LEVOLEUCOVORIN [Fusilev®], LINEZOLID [Zyvox®], MODAFINIL [Provigil®], MONTELUKAST [Singulair®], and MOXIFLOXACIN HCL [Avelox®], amongst others. See details in the chart below.

What exactly is an NDC?
As a reminder, the NDC uniquely identifies a particular manufacturer, drug-strength, and packaging combination. The NDC for your medication is often shown on your prescription bottle as an 11-digit code (see the charts below) or could be formatted as 00000-0000-00 where the first set of numbers identifies the manufacturer, the second set of number identifies the drug and strength, and the third set of numbers identifies the packaging.

Why is there a new NDC?
New NDCs can be added to the Medicare Part D program for a number of reasons including any combination of new manufacturer, drug-strength, delivery form, or packaging. Usually we provide for each NDCs the reason for the NDC addition. With 737 new NDCs, determining the reason was time prohibitive.
