Comparing Rural and Urban Medicare Advantage Beneficiary Characteristics.

Purpose: The Medicare Advantage (MA) program allows Medicare beneficiaries to receive benefits from private plans rather than from traditional fee-for-service (FFS) Medicare. Little is known about the rural and urban differences in the populations that enroll in the MA program, and these differences may be important for setting policy. This brief uses data from the 2012-13 Medicare Current Beneficiary Survey (MCBS) to describe these differences, and combined with county-level data on MA issuer participation, this dataset also allows us to assess the degree to which issuers may engage in selective MA market entry on the basis of demographic characteristics.

Key findings: (1) Rural and urban MA and FFS populations did not differ much on average by any characteristics reported in the data, including age, self-reported health status, cancer diagnosis, smoking status, Medicaid status, or by other variables assessing frailty and presence of chronic conditions. (2) Most measures of access were similar across rural and urban respondents. However, in terms of cost, urban enrollees were less likely to pay an additional premium (beyond Medicare Part A and B) to obtain MA coverage: 42 percent reported doing so in urban places, while 54 percent did so in rural places. (3) While rurality on its own was often a significant predictor of lower issuer participation in a county’s MA market, the addition of other demographic characteristics did not influence the prediction. In other words, we found no evidence, based upon MCBS data, that issuers exclude rural counties due to other demographics.
