Using Medicare Advantage encounter data, this analysis finds that 62% of Medicare Advantage enrollees have at least one chart review record and that diagnoses added from chart reviews increase payments from CMS to insurers for 17% of enrollees. The use of chart reviews varies across the largest Medicare Advantage insurers.
In 2020, more than 22 million Medicare beneficiaries (34%) are enrolled in Medicare Advantage plans, which are mainly HMOs and PPOs offered by private insurers as an alternative to the traditional Medicare program. This data note provides an overview of the Medicare Advantage plans that will be available in 2020, including the variation in the number of plans available by county and plan type. The brief also examines the insurers entering the Medicare Advantage market for the first time and also examines the insurers exiting the market.
Medicare does not cover routine dental care, and two-thirds of the Medicare population have no dental coverage at all. With limited or no dental coverage, some incur high out-of-pocket costs, while others forgo need dental care because they can’t afford it.
This Data Spotlight provides an overview of Medicare Advantage enrollment patterns in March 2014, and examines variations by plan type, state, and firm. It also analyzes trends in premiums paid by beneficiaries enrolled in Medicare Advantage plans and describes the changes in limits on out-of-pocket expenses and prescription drug coverage in the Part D “donut hole” provided by the plans in 2014.
This issue brief analyzes the number and variety of Medicare Advantage plan choices available to beneficiaries in 2015. It describes trends in number of Medicare Advantage plans, plan premiums, and plan quality ratings, including changes in prescription drug coverage and limits on out-of-pocket expenses. This spotlight is part of a series of spotlights tracking key changes in the Medicare Advantage program.
The Medicare open enrollment period allows enrollees to compare plans, stick with their current plan, switch to another plan, or shift to traditional Medicare. This analysis examines the extent to which Medicare Advantage enrollees change plans when given the opportunity. It also analyzes the variation in the rate of plan switching by enrollee and plan characteristics and whether people who voluntarily switch plans tend to move to plans with lower premiums, lower out-of-pocket limits, or higher quality ratings.
Medicare Advantage enrollees were in a plan that included just under half (48%) of all physicians available to traditional Medicare beneficiaries in their area in 2022, on average. The limitations of provider networks illustrate one of the key tradeoffs for beneficiaries in choosing Medicare Advantage for their coverage.
Congress asked the U.S Department of Health and Human Services (HHS) Office of the Inspector General (OIG) to investigate whether Medicaid MCOs are providing medically necessary health care services to their enrollees. OIG found that Medicaid MCOs had an overall prior authorization denial rate of 12.5%–more than 2 times higher than the Medicare Advantage rate. Prior authorization denial rates ranged widely across and within parent firms and states. After a prior authorization request is denied, Medicaid enrollees can appeal, but it’s not always straightforward and many appeals don’t change the initial decision. Unlike in Medicare Advantage, if a Medicaid MCO upholds its original denial, there is no automatic, independent external medical review. OIG found that state Medicaid agency oversight of prior authorization denials is limited. The OIG report underscores concerns about prior authorization and access in Medicaid managed care, keeping this issue at the forefront of ongoing policy discussions.
The Centers for Medicare and Medicaid Services has recently taken actions to increase transparency in Medicare Advantage, however substantial data gaps remain that limit the ability of policymakers and researchers to conduct oversight and assess the program's performance, and for Medicare beneficiaries to compare Medicare Advantage plans offered in their area.
