CMS has a webpage where it posts beneficiary data about COVID, based on claims data. CMS notes the data is not designed for epidemiology purposes, for example, racial data is not adjusted for comorbidities.
The chart below is normalized "per 100,000" beneficiaries. Note that the rate of hospitalization for Black patients is about 4X the rate for whites.
The rate of hospitalization per beneficiary at age 85+ is about triple that for beneficiaries age 65-74. (Data shown is for information received by October 9).
