MCBS community, fee-for-service sample. Beneficiaries with end stage renal disease are excluded.
Other includes Puerto Rico and other territories.
Diagnosis-based health status index computed from provider bills (claims). A higher hierarchical condition categories-diagnostic cost group (HCC-DCG) score indicates poorer health.
NOTES: MCBS is Medicare Current Beneficiary Survey. Beneficiary charcteristics are measured prior to the year in which response status is determined. Data for second (third, fourth) year panel attrition analysis sample weighted by first (second, third) year nonresponse adjusted weights. For second, third, and fourth year panel attrition samples, N = 7,540, N = 6,340, and N = 5,433, respectively.
