As in past years, some 2019 Medicare Part D plans are changing their cost-sharing designs for 2020 prescription drug purchases.  For example, the Cigna-HealthSpring Rx Secure (PDP) will add an additional drug tier to its formulary and with the Humana Walmart Rx Plan (PDP) becoming the Humana Premier Rx Plan (PDP) Tier 3 drugs will change from co-insurance of 20% in 2019 to a flat copay of $42 in all states.

In the following example, the 2019 Cigna-HealthSpring Rx Secure plan formulary had five (5) drug tiers.  In comparison, the 2020 Cigna-HealthSpring Rx Secure plan formulary has added a new 6th drug tier for Select Care Drugs -- with a $0 copay.



In the next example, the 2019 California Humana Walmart Rx Plan (PDP) plan formulary covers 687 medications as Tier Three "Preferred Brand" medications (with a 20% co-insurance) as it becomes the 2020 Humana Premier Rx Plan (PDP) Tier Three "Preferred Brand" will have a $42 copay -- and a much higher premium.


There are approximately 2 million members in the 2019 Humana Walmart Rx Plan (PDP) who will see this change, if they do not select a new plan during AEP.  The 215,000 members of the Express Scripts Medicare - Saver (PDP) will see their cost-sharing Tier 3 Preferred Brands change from a $30 copay to an 18% co-insurance.

In total, 2.7 million members of various stand-alone Medicare Part D plans will see one or more of the drug tiers change cost-sharing from either coinsurance to copay or copay to coinsurance.
