  • KCL-D5W-NACL IV SOLN,
  • TRAMADOL HCL [QDOLO®],
  • TRIAZOLAM [HALCION®], and

Please note that these new generic and brand-name drugs are not available on all Medicare Part D or Medicare Advantage drug plans - and you can review the chart to see the (often limited) number of plan formularies that now include these drugs.


Reminders about Medicare prescription drug plan formulary changes
  1. 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.

  2. In most cases, your Medicare Part D plan will notify you if the plan drops a medication you are currently using.

Good to know: What is the NDC?

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.  You can read more on this site

If your brand-name drug is no longer covered by your Medicare Part D plan, you can use the 30-day notice period (if notice is provided) to:
  • Ask your prescriber about trying the generic.

  • Check for an alternative formulary drug.

  • Ask your plan to cover a non-formulary drug. 
    You will need to work with your doctor or prescriber to explain why you are not able to use the generic medication or why no other formulary drug is acceptable.  If your formulary exception is denied, you have the right to appeal your plan’s decision.

  • Consider using a Special Enrollment Period and move to another Medicare plan that provides coverage of all your prescription and health needs.
