Our exclusive analysis shows that preferred cost-sharing networks now dominate the landscape.
- In 2015, 81% of seniors enrolled in PDPs with preferred cost sharing pharmacy networks.
- Humana’s three preferred network plans grew by 19% and now enroll one in five Part D beneficiaries.
- Meanwhile, CVS Health’s SilverScript, which has the largest open network plan, lost members in its preferred plan but gained members in its open network plan. (corrected)
DON'T ACT LIKE YOU'RE NOT IMPRESSED
Data on PDP enrollment are available from this CMS page: Medicare Advantage/Part D Contract and Enrollment Data. Note that these data reflect enrollments accepted through December 4, 2014. The final 2015 numbers will differ, because the open enrollment period ended three days later, on December 7, 2014.
Last October, I identified the Medicare Part D prescription drug plans (PDP) with preferred network structures. See EXCLUSIVE: For 2015, almost 9 out of 10 Medicare Part D plans will have a preferred pharmacy network. My evaluation includes only stand-alone PDPs. I eliminated the following plans from the sample:
- Employer-sponsored plans
- Medicare Advantage PDPs (MA-PDP)
- Plans from U.S. territories and possessions (American Samoa; Guam; Northern Mariana Islands; Puerto Rico; Virgin Islands)
- Employer/union-only group plans (contracts with "800 series" plan IDs)
KIND OF A BIG DEAL
In 2015, 66 plans have preferred networks. These plans operate 870 regional PDPs, which account for 87% of the total regional PDPs for 2015.
Based on the initial enrollment figures, these 66 plans enrolled 15.4 million people, or 81% of the PDP total through December 4, 2014.
The top three parent organizations—UnitedHealthcare, Humana, and CVS Health's SilverScript—account for almost two-thirds of enrollment in stand-alone Part D plans. The top 10 companies (shown below) are 91% of enrollment.

GREAT ODIN'S RAVEN!
UnitedHealthcare remains the enrollment leader. UnitedHealthcare offers two AARP plans with preferred cost sharing pharmacy networks. These plans have 4.9 million (25.8%) of enrollees.
Humana remains the growth leader. Humana has three preferred network plans: Humana Enhanced, Humana Preferred Rx Plan (its original plan with Walmart), and the co-branded Humana Walmart Rx Plan. These three plans collectively have 4.1 million (21.7%) of total Part D enrollees. That’s 19% higher than Humana’s 3.5 million total from last January.
CVS Health’s SilverScript was an open network winner. CVS Health’s SilverScript Choice is the largest open network plan. It has 3.2 million members, making it the largest plan without a preferred network. By contrast, the SilverScript Plus preferred network plan has only 137,363 enrollees, or 0.7% of the total. SilverScript’s total enrollment (preferred plus open) increased to 3.3 million, from the 3.1 million members enrolled one year ago. (corrected)
Other major preferred plans did well. All three Cigna-HealthSpring plans (Rx Secure, Rx Secure-Xtra, and Rx Secure-Max) have preferred cost sharing networks. Enrollment is 1.4 million, or 7.3% of the total. Wellcare, the fifth-largest parent organization, has three preferred network plans, with 1.1 million enrollees (6.0%).
Aetna has stirred up trouble. Aetna’s two plans, both of which have preferred cost sharing, enrolled 692,000 seniors (3.6%). The Aetna Medicare Rx Saver PDP has preferred cost-sharing in only 29 regions, and no preferred cost sharing in 5 regions. The Aetna Medicare Rx Premier PDP has preferred cost sharing in all 34 regions. However, Aetna’s 2015 plans have been controversial, because of allegations that its online plan information did not accurately identify preferred pharmacies. See the Chicago Tribune's Aetna mistake could complicate some Part D drug refills.
Is Rite Aid laughing like a ventriloquist’s dummy? Symphonix has two co-branded preferred cost sharing plans: Symphonix Rite Aid Premier Rx and Symphonix Rite Aid Value Rx. Both plans are offered in 18 regions. In 12 other regions without a Rite Aid pharmacy, two plans—Symphonix Premier Rx and Symphonix Value Rx—have preferred cost-sharing. The Symphonix plans enrolled 143,400 people, or just 0.8% of the January total. Given the negative impact of Part D plans on pharmacy margins, Rite Aid may be an unexpected winner.
In 2014, CMS proposed major changes to Part D’s pharmacy regulations that would have eliminated many preferred network benefits. After many outside stakeholders sharply criticized the changes, CMS withdrew many of the proposed regulations. The popularity and success of preferred networks in Medicare Part D suggests that they will remain a significant part of the program.
Data covering the entire open enrollment period will be released in February. Until then, you stay classy, Drug Channels.
CORRECTION: In the original version of today's article, there is a small error. We miscalculated CVS Health's SilverScript enrollment for January 2014, erroneously concluding that its open network plan had lost members. In reality, its preferred network plan lost members, while its open network plan gained members. We have corrected the text, and apologize for the error.
