the standard population, we relied on this aspect of the database to account for separate
copayments and cost sharing payments applying to the professional and facility components of
services.
Preventive care is defined, and claims are categorized, using the CPT code list from the US
Preventive Services Task Force. The services defined as preventive care correspond to the
preventive services covered without cost sharing under section 2713 of the Affordable Care Act.
To prepare the data for use in the continuance tables, several enrollment restrictions are applied
to ensure that the data represent a full year of utilization experience for enrollees. The full data
include 39,184,536 enrollees and 767,517 PPO/POS (Point of Service) plans. Restricting to
group PPO/POS with drug coverage and at least 50 enrollees brings the count down to
15,243,652 enrollees and 61,647 plans. In the absence of plan benefit design information directly
from the plans that submitted data to this commercial database, the cost-sharing parameters that
apply to individuals are inferred from the spending data to aid in the construction of the
continuance tables. To ensure that the imputation procedure can be applied effectively, plans
with utilization data that are likely incomplete are excluded. Specifically, to be included, plans
with more than 50 members must be PPO/POS plans with positive drug enrollment in at least
one month, and plans with over 1,000 members must additionally have at least one claim with a
maternity DRG. Moreover, all plans must have at least one member with over $5,000 in
spending. For plans that meet these requirements, the 90
th
percentile of positive deductibles that
are at least $250 lower than the amount of total spending for all enrollees within a PCC is set as
the plan deductible, and the 90
th
percentile of beneficiary spending above $1,000 over all
enrollees within a PCC is set as the plan maximum out-of-pocket (MOOP) limit. The
coinsurance rate is estimated by examining the coinsurance variable on claims for plan members
with spending between the deductible and the MOOP. Spending data are also used to impute
copayments for several services including in-patient (IP) services, emergency room (ER)
services, primary care office visits, specialist office visits, and five tiers of prescription drugs:
generics, preferred brand drugs, non-preferred brand drugs, and specialty high-cost drugs.
To prepare the data for use in the continuance tables, additional restrictions are made to exclude
implausible plan designs. Plans with zero spending for all enrollees and plans with imputed
coinsurance rates that fall outside the range of 0-100% are dropped. Additionally, plan-
demographic group combinations with negative realized actuarial value are dropped. Enrollees
with unspecified sex are also excluded. The resulting database consisting of 12,553,043
enrollees and 46,359 plans was used to construct the continuance tables, subject to the additional
adjustments identified in the next two sections of this document.
Standard Population Development and Adjustment from Primary Claims Data
The claims data, excluding the populations and plans noted above, provide the raw material for
developing a standard population based on the expected enrollment in individual plans for the
years 2014 and beyond. Utilization and spending in this data do not necessarily represent
utilization and spending in the population expected to participate in the individual and small
group markets in 2014. Further adjustment is therefore necessary to reflect the expected
enrollment in plans required to use the AV Calculator in 2014.
We anticipate that the standard population should be composed of the following:
