A central concern is the potential incentive for Medicare Advantage plans to deny access to services and payments to providers in an effort to increase profits, the office said. Insurers receive a fixed amount per patient, regardless of the amount of care received.
AHIP, a leading industry group formerly known as America’s Health Insurance Plans, disputed the inspector general’s report, saying it was based on a very limited sample. The agency reviewed 250 prior authorization denials in the first week of June 2019.
“We discourage using this report to draw general conclusions about MA’s overall performance,” spokeswoman Kristine Grow said, noting recipients’ high satisfaction ratings with their plans.
Additionally, AHIP said the report highlights that Medicare Advantage insurers approve the vast majority of claims for services and payments. (The Inspector General’s office also said insurers issue millions of denials each year.)
Another industry group, Blue Cross Blue Shield Association, did not return a request for comment.
Inspector General’s Report
The plans rejected some requests for prior authorization from medical providers that likely would have been covered by traditional health insurance, according to the inspector general’s office. Of the denied claims, about 13% met Medicare coverage rules.
The bureau identified two common reasons behind the denials. In some cases, insurers used clinical criteria not contained in Medicare coverage rules, such as requiring an X-ray before allowing more advanced imaging, such as an MRI. And insurers have ruled in some cases that the documentation was not sufficient for approval, even though the inspector general’s medical examiners found that existing medical records were sufficient to justify the need for the services.
Additionally, Medicare Advantage plans declined claims primarily due to human error during manual claim review or due to system processing errors. About 18% of denied claims met Medicare coverage rules and Medicare Advantage billing rules.
Some of the denied pre-authorization and payment requests that complied with coverage and billing rules were later cancelled, often because the recipient or provider appealed.
Recommendations for improvement
The Inspector General’s Office recommends that the Centers for Medicare and Medicaid Services, which oversees Medicare Advantage, issue new guidance on the appropriate use of insurers’ clinical criteria in medical necessity reviews and update its protocols for audit to resolve the issues identified in the report. It also suggests that CMS Direct Medicare Advantage plans to take additional steps to reduce manual review and system errors.
CMS said it agreed with all of these recommendations and was in the process of determining next steps.
Medicare Advantage plans can institute additional requirements to better define the need for a medical service, but they cannot be more restrictive than traditional state and local Medicare coverage policies, the agency said. It performs plan compliance audits and targets areas of concern, such as departments with high denial rates. Regimes whose repeated violations are found are subject to penalties, sanctions and termination of the contract.
In its response to the report, CMS noted that the average number of issues cited per audit decreased by approximately 70% between 2012 and 2019 – a statistic that AHIP also highlighted in its commentary.
