About DVA
DaVita is the largest provider of dialysis services in the United States, boasting market share that eclipses 35% when measured by both patients and clinics. The firm operates over 3,000 facilities worldwide, mostly in the U.S., and treats over 240,000 patients globally each year. Government payers dominate U.S. dialysis reimbursement. DaVita receives about two thirds of U.S. sales at government (primarily Medicare) reimbursement rates, with the remainder coming from commercial insurers. However, while commercial insurers represented only about 10% of the U.S. patients treated, they represent nearly all of the profits generated by DaVita in the U.S. dialysis business.
