If we’ve learned anything from the federal government’s 18-year experiment with Medicare Advantage plans–private insurance plans offering Medicare benefits–it’s that there is every reason for the government not to pay them upfront for their services. Upfront payments simply give the for-profit insurers an incentive to hold on to as much of the money they receive as possible. A new audit report by the Office of the Inspector General (OIG) suggests that the government’s willingness to pay Medicare Advantage plans more for patients with multiple diagnoses gives them an incentive to report to the government that their members have multiple diagnoses. The OIG finds that Florida Humana Medicare Advantage has done just that, overcharging the government by nearly $200 million in one year alone.
There is little question that the federal government is spending more on people in Medicare Advantage plans than it does in traditional Medicare. A recent MedPAC post reported that Medicare Advantage has cost the Treasury more than traditional Medicare every year since its inception. To be sure, Medicare Advantage plans are all different and some could be serving their members and the American public well. But, there is substantial evidence that many are not. An OIG 2020 report found that in 2019 alone, the federal government made $16 billion in improper payments to Medicare Advantage plans, more than 6 percent of total payments of about $244 billion.
The OIG found that in a sample of just 200 Humana Medicare Advantage members in Florida, the government could not validate more than 10 percent of the diagnosis codes that Humana submitted. The OIG’s audit did not include other Medicare Advantage plans. It’s probably fair to assume that when other Medicare Advantage plans are audited–as the OIG plans on doing–that it’s not unlikely that the OIG will have similar findings.
In addition to a refund of the $197.7 million in net overbilling, the OIG wants Humana to improve its policies so that they are in compliance with federal requirements for diagnosis codes. However, if the punishment is simply for Humana to reimburse the government for the faulty coding, what is the incentive for Humana, or any other Medicare Advantage plan for that matter, to improve its compliance?
Unsurprisingly, Humana disagreed with the OIG’s findings and was able to get the OIG to reduce the overcharge amount down from $261 million to $197. Still, it contests the OIG’s findings and appears to be considering an appeal. All in, across the US, Humana has 4 million Medicare Advantage members.
