a
Denominator is all enrollees have complete Parts A&B with no HMOs in 2016.
b
Denominator is all enrollees have complete Parts A&B, with no HMOs in 2015 and 2016.
c
Denominator is all enrollees aged 66+ and have complete Parts A&B, with no HMOs in 2015 and 2016. Life expectancy is estimated only for those older than age 65 because the algorithm was derived from those older than age 65.
