OIG Recommends Targeted Audits of MS-DRGs

OIG Recommends Targeted Audits of MS-DRGs February 25, 2021

Last week, the OIG released a report on Part A claims for inpatient hospital stays from FY 2014 through FY 2019. The report indicates that approximately 50% of Medicare payments for inpatient hospital stays were based on the highest severity MS-DRG.  These payments totaled $54.6 billion dollars. The report also highlighted some notable trends:

  • The overall number of claims at the highest MS-DRG has risen 20%.
  • The average length of stay for the highest MS-DRGs has decreased.
  • Over half of the claims contained only 1 qualifying diagnosis for the highest MS-DRG.
  • The most frequently billed MS-DRG was severe sepsis with a major complication (MS-DRG 871).
  • Certain MS-DRGs have been identified as frequently having shorter than the average length of stay including; heart failure and shock (MS-DRG 291), pneumonia (MS-DRG 193), and renal failure (MS-DRG 682).

The OIG stressed that claims for the highest level MS-DRGs are susceptible to inappropriate billing patterns including up-coding.  They recommended CMS initiate targeted reviews of MS-DRGs and specifically include hospitals who frequently bill the highest MS-DRG levels. We recommend hospitals perform internal analysis of their MS-DRG billing as well as conduct internal reviews of the MS-DRGs specifically identified in the OIG report as well as any other frequently billed highest level MS-DRGs.
