Independence Blue Cross, the Philadelphia-based health insurer, has agreed to pay $22.5 million to resolve allegations that it kept Medicare Advantage overpayments tied to inaccurate diagnosis codes, the U.S. Department of Justice announced Sept. 30.
The government alleged that for payment years 2017 through 2021, the insurer failed to withdraw diagnosis codes for its Medicare Advantage members that its own chart reviews did not support. The company did not admit wrongdoing. "The claims resolved by the settlement are allegations only and there has been no determination of liability," the Justice Department said.
No change to members' benefits has been announced. But the case matters to anyone who pays for Medicare through taxes and premiums, because inflated payments to private plans raise the program's overall cost.
The Allegations Behind the Settlement
Medicare Advantage plans receive a set monthly amount for each enrollee, and that amount rises when diagnosis codes show a person is sicker. The system, called risk adjustment, is meant to make sure plans are paid fairly for covering people with serious conditions.
According to the Justice Department, IBX used nurse reviewers to examine medical records and sent Medicare additional diagnosis codes found in those reviews, which increased payments. When the same reviews did not support codes IBX had already submitted, the government alleged, the insurer kept those codes rather than deleting them. Prosecutors also said IBX certified to the Centers for Medicare & Medicaid Services that its data were accurate.
The HHS Office of Inspector General summarized the claim as "failing to withdraw inaccurate and untruthful diagnosis codes for its Medicare Advantage Plan enrollees in order to improperly retain overpayments from Medicare."The government did not publicly identify specific medical conditions involved.
The case began with a whistleblower lawsuit filed by a former IBX employee, United States ex rel. Crawford v. Independence Blue Cross, in federal court in Philadelphia. The whistleblower will receive $3,825,000 of the settlement. Under the False Claims Act, private citizens can sue on the government's behalf and receive a share of any recovery.
Federal Officials and IBX Respond
"The government pays private insurers over $530 billion each year to care for Americans enrolled in Medicare Advantage," said Brett A. Shumate, assistant attorney general for the Justice Department's Civil Division. "When insurers knowingly and improperly retain inflated payments based on inaccurate and untruthful diagnoses, we will hold them accountable whether they are a small regional plan or a large nationwide organization."
David Metcalf, U.S. Attorney for the Eastern District of Pennsylvania, said, "The Medicare Advantage program depends on accurate data about patient health. When insurers inflate their profits and the government's costs by submitting or failing to correct unsupported diagnoses, my office will continue to hold them accountable."
IBX disputed the characterization in a statement to Becker's Payer Issues. The company said it "chose to resolve the matter to avoid the delay, uncertainty, expense, and distraction of prolonged litigation" and that "this matter was not about the quality of care our members received." The company added that many major health plans "have faced similar government scrutiny regarding Medicare Advantage risk adjustment requirements and practices."
The Wider Cost of Coding in Medicare Advantage
The case reflects a broader concern about coding intensity, the practice of recording more diagnoses for Medicare Advantage members than would appear for similar patients in traditional Medicare. Coding intensity is not automatically fraud, since some extra codes reflect real conditions, but unsupported codes raise costs.
According to a KFF analysis of coding intensity, payments to Medicare Advantage plans in 2026 are $76 billion higher than traditional Medicare would spend for the same people, with $28 billion attributed to coding intensity. KFF also found that diagnoses added through chart reviews raise payments for about one in six Medicare Advantage enrollees.
That money matters to households. About 35.2 million people, or 55% of eligible Medicare beneficiaries, are enrolled in Medicare Advantage in 2026, KFF reports. Higher payments to Medicare Advantage plans also push up Part B premiums for all beneficiaries, including those in traditional Medicare, according to KFF.
For IBX members, the practical takeaway is to review the paperwork that already arrives. An Explanation of Benefits lists services billed under a member's name. Diagnoses that do not match a person's actual health history can be raised with their doctor or plan, since inaccurate records can follow patients into future care.
Members who suspect billing or coding fraud can report it to the HHS-OIG hotline at 1-800-HHS-TIPS. Medicare open enrollment begins Oct. 15, giving beneficiaries a chance to compare plans for 2027, though this settlement is not on its own a reason to switch coverage.
CMS has also finalized a policy to exclude diagnoses from certain unlinked chart reviews from 2027 payments, a change CMS estimates will reduce average Medicare Advantage payments by about 1.5%.
