Medicare Advantage risk adjustment continues to be an area worth watching.
In a newly released audit, HHS-OIG found that many of the selected high-risk diagnosis codes it reviewed were not supported by the underlying medical records, resulting in a significant estimate of potential overpayments.
The broader program-integrity lesson goes well beyond any single organization.
A diagnosis code is a signal.
Advanced analytics can identify high-risk diagnoses, unusual provider patterns, coding concentrations and relationships at scale.
But the data still has to be tested against the evidence.
That requires medical expertise.
It may require deeper investigation.
And when the findings reveal a broader pattern, that intelligence should feed back into detection.
AI + Advanced Analytics + Scheme Detection + Medical Expertise + Investigation
That is how organizations move from identifying an anomaly to understanding whether the underlying payment is defensible.
Because the goal isn’t simply to find more codes.
It’s to understand what the evidence actually supports.
