Beneficiary Enrollment

library(provider)

The Medicare Monthly Enrollment dataset provides current monthly information on the number of Medicare beneficiaries with hospital/medical/prescription drug coverage, available for several geographic areas including national, state/territory, and county. The data can be further broken down by health care delivery (e.g. Original Medicare vs. Medicare Advantage) and includes enrollee counts on a rolling 12-month basis, providing information on yearly trends as well.

Examples

The level argument has three options: National, State, and County.

Setting it to National will return yearly and monthly national totals:

beneficiary_enrollment(level = "National") |> head(10)
#> Error in beneficiary_enrollment(level = "National"): could not find function "beneficiary_enrollment"

Setting level to National and the period argument to Year will return yearly national totals only:

beneficiary_enrollment(level = "National", period = "Year") |> head(10)
#> Error in beneficiary_enrollment(level = "National", period = "Year"): could not find function "beneficiary_enrollment"

Setting level to State and period to Year will return yearly totals for each state:

beneficiary_enrollment(level = "State", period = "Year") |> head(10)
#> Error in beneficiary_enrollment(level = "State", period = "Year"): could not find function "beneficiary_enrollment"

beneficiary_enrollment(level = "State", 
                       period = "Month") |> 
  head(10)
#> Error in beneficiary_enrollment(level = "State", period = "Month"): could not find function "beneficiary_enrollment"

state & county

Select a particular state:

beneficiary_enrollment(period = "Year", 
                       level = "State", 
                       state = "GA") |> 
  head(10)
#> Error in beneficiary_enrollment(period = "Year", level = "State", state = "GA"): could not find function "beneficiary_enrollment"

Each county in that state:

beneficiary_enrollment(period = "Year", 
                       level = "County", 
                       state_name = "Georgia")

Or a particular county:

beneficiary_enrollment(period = "Year", 
                       level = "County", 
                       state = "GA", 
                       county = "Lowndes") |> 
  head(10)
#> Error in beneficiary_enrollment(period = "Year", level = "County", state = "GA", : could not find function "beneficiary_enrollment"
