Reminders about Medicare prescription drug plan formulary changes
- Medicare Part D plans (PDPs and MAPDs) can change their formulary or drug list during the year and may drop one of your formulary medication mid-year for specific Medicare-allowable reasons (such as a new generic drug is available), but there are steps you can take if your medication is no longer covered by your prescription drug plan.
- In most cases, your Medicare Part D plan
will notify you if the plan drops a medication you are currently using.
The NDC or National Drug Code is used to uniquely identify a particular drug, manufacturer, strength, and packaging combination. The NDC 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 drug manufacturer, the second set of number identifies the product and strength, and the third set of numbers identifies the packaging.
