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 us, and treats about 250,000 patients globally each year. Government payers dominate us dialysis reimbursement. DaVita receives about two thirds of us sales at government (primarily Medicare) reimbursement rates, with the remainder coming from commercial insurers. While commercial insurers represent only about 10% of the us patients treated, they represent nearly all of the profits generated by DaVita in the us dialysis business.
