How Would Your Organization Defend This Auditing Accusation?


The Office of Inspector General (OIG) is always working on audits in a pursuit of accurate reporting and reimbursement. A recently published OIG audit report can provide great information on how to protect providers and risk adjustment payers from serious financial losses by showing exactly what the OIG is looking for and how the payer (or provider) may have defended their coding choices. In this article, you will see how the OIG audited the HCC for major depressive disorder and what Anthem did to defend its reporting.

$636 Million in Overpayments Made by Medicare to Providers for Neurostimulators

Coding for a Performance of an X-ray Service vs. Counting the Work as a Part of MDM


When x-rays are audited on the same date as an E/M encounter we have one of three decisions to make about the work that went into the radiological exam when the practice owns x-ray equipment and does their own interpretations internally. First, we must determine whether the x-ray was...

Medicare Auditors Caught Double-Dipping


Overlapping extrapolations require providers to pay twice. Some Medicare auditors have been caught “double-dipping,” the practice of sampling and extrapolating against the same set of claims. This is like getting two traffic tickets for a single instance of running a red light. This seedy practice doubles the amount...

Will Your Critical Care Services Pass An Audit?

Is Coding Based on Addendums or Late Entries Putting You At Risk of Audit Failure?


Independent Health, another Medicare Advantage Organization, has been named in a qui tam (whistleblower) lawsuit and enjoined by the DOJ for allegations of fraudulently upcoding to increase beneficiary risk adjustment scores to obtain higher reimbursement. It appears they used DxID, LLC, a coding consulting subsidiary of Independent Health to retrospectively identify and have providers addend unsupported diagnoses. How is your organization actively protecting against accusations of upcoding by improper use and reporting of diagnoses from provider addenda?
