The Office of the Inspector General (OIG) issued a report earlier this year concluding that “hospitals are increasingly billing for inpatient stays at the highest severity level,” emphasizing that “stays at the highest severity level are vulnerable to inappropriate billing practices, such as upcoding.” The OIG recommended that “CMS [Centers for Medicare & Medicaid Services] conduct targeted reviews of MS-DRGs and hospital stay that are vulnerable to upcoding.” Essentially, the OIG is saying, “We have encouraged providers to compliantly code the complexity and severity of the Medicare population accurately. As a result of these compliant hospital efforts, we were shocked to learn that old people are sick and, by default, hospitals must be wrong.” However, right or wrong, increased scrutiny is coming to hospitals.

Webinar Information:
  • Date: Wednesday, May 5, 2021
  • Time: 2:00 pm ET | 11:00 am PT
  • Duration:  60 minutes

Why does this matter to Utilization Review, CDI/Coding, & Revenue Cycle leaders?

Because MS-DRG coding will likely become a significant issue for the OIG and RACs moving forward (CMS suggested that it would be sharinging these data with the RACs).

Join Versalus Health as we reveal a secret… the flaws in the OIG methodology are basic ones that are also extremely prevalent across hospital revenue cycle data analytics, nationwide.

Attend this webinar to learn:

  • Why the methodology used by the OIG in its report is flawed: gain an in-depth understanding of the report analyses, findings, and repercussions
  • How Utilization Review, Documentation, and Coding outcomes and data are interdependent and critical areas of the Clinical Revenue Cycle
  • How the potential for additional auditor attention to Documentation & Coding can impact your organization’s efforts
  • How to ensure compliance and audit defensibility of all appropriate Medicare DRG payments

We hope you can join us for this webinar!
