Medicare Advantage plans approve most requests for coverage for care, according to a group for health insurers.
When the plans do deny preauthorization request incorrectly, the main reason is often lack of clear advice from Medicare program managers, the group says.
America's Health Insurance Plans — a Washington-based group for health insurers — defended the plans' coverage decisions in a response to a report, released Thursday, by the U.S. Department of Health and Human Services' Office of Inspector General.
The Medicare Advantage program lets health insurers provide plans that look, to the enrollees, like alternatives to the original Medicare Part A hospitalization and Part B physician and outpatient services coverage.
HHS OIG investigators said they analyzed a sample of about 250 care preauthorization denials issued during one week in June 2019, and that they believe that 13% of the denials were wrong.
AHIP said it believes that the HHS OIG report, and press coverage of the report, gave a misleading impression of Medicare Advantage plans' performance.
"The OIG noted that the overwhelming majority (95%) of prior authorization requests in 2018 were approved," AHIP said.
HHS OIG investigators objected to Just 33 of the 247 preauthorization denials analyzed, the group added.
