Top 10 insurers in the Part D arena: UnitedHealth at the top
The ten largest Part D plan sponsors in 2014--in order of market share--are UnitedHealth Group, Humana, CVS Caremark, Express Scripts, Aetna, Cigna, WellCare Health Plans, Kaiser Permanente, WellPoint and Envision.
These 10 companies account for more than three-fourths of all enrollees, with UnitedHealth alone accounting for more than one in five Part D enrollees, including 22 percent of prescription drug plans (PDP) enrollees and 21 percent of Medicare Advantage prescription drug plans (MA-PD), the study says.
This pattern of a few plan sponsors having a substantial share of Part D enrollment has held over the program's first nine years, the study's authors said.
The top 10 have enrolled 29.5 million beneficiaries in either a stand-alone PDP or an MA-PD plan. The share of enrollment in the ten largest plans in 2014 (79 percent) is higher than in 2006 (69 percent). In 2006, the top three firms also accounted for about half of all enrollees.
UnitedHealth and Humana have been the two largest Part D plan sponsors from the start of the program, but their combined share of enrollment has dropped from 45 percent in 2006 to 38 percent in 2014, the study found. UnitedHealth, due in part to its successful marketing relationship with AARP, has maintained its top position for all nine years of the program and has seen its enrollment grow by about 43 percent since 2006.
Six of the top ten firms in 2014 sponsor both stand-alone PDPs and MA-PD plans. Kaiser Permanente is the only sponsor among the top ten that offers only MA-PD plans, and WellPoint--which recently announced it plans to change its name to Anthem--is the only other firm with more MA-PD enrollees than PDP enrollees.
