Independence Blue Cross to pay $22.5M; DOJ alleges one-way MA chart reviews

On September 30, 2026, the Justice Department announced that Independence Blue Cross (IBX), a Pennsylvania insurer, agreed to pay $22.5 million to resolve False Claims Act allegations that it failed to withdraw inaccurate Medicare Advantage diagnosis codes and improperly retained the resulting overpayments. DOJ's description centers on a chart-review workflow: codes went up when reviews supported them, and stayed on file when reviews did not.

What DOJ announced

According to the DOJ Office of Public Affairs release, IBX agreed to pay $22.5 million to resolve allegations that it violated the False Claims Act by failing to withdraw inaccurate and untruthful diagnosis codes for its Medicare Advantage enrollees. The United States alleges IBX submitted inaccurate patient diagnosis data to CMS that inflated risk-adjustment payments, knowingly failed to withdraw that data and repay CMS, and falsely certified in writing that the data was accurate and truthful.

DOJ states the claims resolved by the settlement are allegations only and there has been no determination of liability.

The coding pattern DOJ describes

For payment years 2017 through 2021, the United States contends IBX operated a "chart review" program in which nurse reviewers reviewed medical records and identified medical conditions the charts supported. IBX relied on those results to submit additional diagnosis codes to CMS for more payment.

The government also contends that the same chart reviews did not substantiate some diagnosis codes IBX had previously reported to CMS, and that IBX did not delete or withdraw those codes. Deleting them would have required reimbursing CMS. In DOJ's words, IBX allegedly used chart-review results to find places to seek additional payments while ignoring the same results when they showed IBX was overpaid.

Desk shorthand for that asymmetry is a one-way chart review: add when supported, never delete when not. Two-way review is the compliance opposite: if the record does not support a previously submitted diagnosis, the code comes off.

Why this lands on a risk-adjustment coder's desk

This is not a provider-query case and it is not a named-HCC hit list. The DOJ release does not name specific ICD-10-CM codes or CMS-HCC categories. The operational lesson is the direction of the review.

If your shop runs retrospective chart reviews or vendor chart reviews for Medicare Advantage risk adjustment, the government's theory here is that using review findings only to add codes, while leaving unsupported prior codes in place, can become a False Claims Act problem. The Monday-morning check is simple: when a chart review cannot substantiate a diagnosis already on the MAO's submission file, treat deletion and repayment rules as part of the same workflow as the add.

Use MEAT criteria as the documentation filter before any add stays on a claim, and keep the encoder and ICD-10-to-HCC tools for confirming what the current model actually maps when a diagnosis is legitimately supported.

How the case surfaced

The settlement resolves a lawsuit filed under the False Claims Act's qui tam whistleblower provisions. The case is captioned *United States ex rel. Crawford v. Independence Blue Cross*, No. 20-cv-5818, in the U.S. District Court for the Eastern District of Pennsylvania. DOJ says the whistleblower, a former IBX employee, is to receive a $3,825,000 share of the settlement amount.

The matter was handled by the Justice Department's Civil Division, Commercial Litigation Branch, Fraud Section, and the U.S. Attorney's Office for the Eastern District of Pennsylvania, with HHS-OIG.

What this does not change on the claim

The release does not rewrite ICD-10-CM indexing, does not change CMS-HCC V28 mappings, and does not announce a new RADV schedule. It is an enforcement resolution about alleged diagnosis-data integrity and the duty to withdraw unsupported codes once a plan's own review finds them unsupported.

Related HCC Buddy coverage on MA diagnosis enforcement includes the Villages Health $541.5M settlement coder lessons and the Monogram Health $2.4M HCC coding FCA. Those stories name different defendants and different alleged patterns; do not treat IBX as a rewrite of either.

Where coders should tighten this week

Pull recent retrospective chart-review batches and confirm the shop has a documented path for deletes, not only adds. If a nurse or coder review cannot substantiate a previously submitted diagnosis, escalate through your compliance process for withdrawal and any required repayment steps under your MAO's rules. Do not invent codes or HCCs from this release; the government did not publish a condition list here.
