Medicare Advantage Chart Reviews Are Associated With Billions in Additional Payments for Some Plans.

ABSTRACT:

Background

In the Medicare Advantage (MA) program, private plans receive capitated payments that are adjusted based on their enrollees' number and type of clinical conditions. Plans have the ability to review charts to identify additional conditions that are not present in claims data, thereby increasing risk-adjusted payments. Recently the Government Accountability Office released a report raising concerns about the use of these chart reviews as a potential tool for upcoding.

Objectives

To measure the extent to which plans receive additional payments for chart reviews, and the variation in chart reviews across plans.

Research design

In this cross-sectional study we use 2015 MA Encounter data to calculate how many additional diagnoses codes were added for each enrollee using chart reviews. We then calculate how these additional diagnosis codes translate to additional reimbursements across plans.

Subjects

A total of 14,021,692 beneficiaries enrolled in 510 MA contracts in 2015.

Measures

Individual and contract level hierarchical condition category codes, total plan reimbursement.

Results

Chart reviews were associated with a $2.3 billion increase in payments to plans, a 3.7% increase in Medicare spending to MA plans. Just 10% of plans accounted for 42% of the $2.3 billion in additional spending attributed to chart review. Among these plans, the relative increase in risk score from chart review was 17.2%. For-profit plans engaged in chart reviews substantially more frequently than nonprofit plans.

Conclusions

Given the substantial and highly variable increase in payments attributable to chart review, further investigation of the validity of this practice and its implications for Medicare spending is needed.

Project description:BackgroundDifferences in the control of blood pressure, cholesterol, and glucose among the various racial and ethnic groups of Medicare enrollees may contribute to persistent disparities in health outcomes.MethodsAmong elderly enrollees in Medicare Advantage health plans in 2011 who had hypertension (94,171 persons), cardiovascular disease (112,039), or diabetes (105,848), we compared the respective age-and-sex-adjusted proportions with blood pressure lower than 140/90 mm Hg, low-density lipoprotein cholesterol levels below 100 mg per deciliter (2.6 mmol per liter), and a glycated hemoglobin value of 9.0% or lower, according to race or ethnic group. Comparisons were made nationally and within regions and health plans, and changes since 2006 were assessed.ResultsBlack enrollees in 2006 and 2011 were substantially less likely than white enrollees to have adequate control of blood pressure (adjusted absolute differences in proportions of enrollees in the 2 years, 7.9 percentage points and 10.3 percentage points, respectively), cholesterol (11.4 percentage points and 10.2 percentage points, respectively), and glycated hemoglobin (10.1 percentage points and 9.4 percentage points, respectively) (P<0.001 for all comparisons). Differing distributions of enrollees among health plans accounted for 39 to 59% of observed disparities in 2011. These differences persisted in 2011 in the Northeast, Midwest, and South (6.9 to 14.1 percentage points, P<0.001 for all comparisons) but were eliminated in the West for all three measures (<1.5 percentage points, P≥0.15). Hispanic enrollees were less likely than whites in 2011 to have adequate control of blood pressure (adjusted difference, 1.6 percentage points), cholesterol (adjusted difference, 1.0 percentage points), and glycated hemoglobin (adjusted difference, 3.4 percentage points) (P≤0.02 for all comparisons). Asians and Pacific Islanders were more likely than whites to have adequate control of blood pressure (difference, 4.4 percentage points; P<0.001) and cholesterol (5.5 percentage points, P<0.001) and had similar control of glycated hemoglobin (0.3 percentage points, P=0.63).ConclusionsDisparities in control of blood pressure, cholesterol, and glucose have not improved nationally for blacks in Medicare Advantage plans, but these disparities were eliminated in the West in 2011.

Project description:ObjectivesWe assessed the characteristics of older Mexican American enrollees in traditional fee-for-service (FFS) and Medicare Advantage (MA) plans and the factors associated with disenrollment from FFS and enrollment in MA plans.DesignLongitudinal study linked with Medicare claims data.SettingThe Hispanic Established Populations for the Epidemiologic Study of the Elderly.ParticipantsCommunity-dwelling Mexican American older adults (N = 1455).MeasurementsWe examined insurance status using the Medicare Beneficiary Summary File and estimated the association of sociodemographic and clinical factors with insurance plan switching.ResultsAmong Mexican American older adults, FFS enrollees were more likely to be born in Mexico, speak Spanish, have lower levels of education, and have more disability than MA enrollees. Older adults with a larger number of limitations of instrumental activities of daily living (odds ratio [OR] = .50; 95% confidence interval [CI] = .26-.98) and more social support (OR = .70; 95% CI = .45-.98) were less likely to switch from FFS to MA compared with older adults with no limitations and less social support. Additionally, older adults living in counties with a greater number of MA plans were more likely to switch from FFS to MA (OR = 2.1; 95% CI = 1.45-3.16), compared with counties with a lower number of MA plans. In counties with a higher number of MA plans, older adults with more social support had lower odds of switching from FFS to MA (OR = .48; 95% CI = .28-.82) compared with older adults with less social support.ConclusionCompared with those enrolled in MA, older Mexican American adults enrolled in Medicare FFS are more socioeconomically disadvantaged and more likely to demonstrate poor health status. Stronger social support and increased physical limitations were strongly associated with less frequent switching from FFS to MA plans. Additionally, increased availability of MA plans at the county level is a significant driver of enrollment in MA plans. J Am Geriatr Soc 68:313-320, 2020.
