Hayes’ Healthcare audit and revenue integrity analysis finds COVID-19 claims and bundling errors driving denials

Oct. 29, 2021

Bundling errors continue to wreak havoc on hospital bottom lines in 2021, causing 34% of inpatient charge denials with an average value of $5,300 each. That’s according to an auditing and revenue integrity report analyzing more than $100 billion worth of denials and $2.5 billion in audited claims released today by Hayes, makers of MDaudit, an auditing, billing compliance and revenue integrity platform for healthcare organizations.

“Healthcare Auditing and Revenue Integrity: 2021 Benchmarking and Trends Report” shares the findings of Hayes’ review of professional and hospital claims audited in MDaudit Enterprise during the first 10 months of 2021. Internal auditors identified a significant number of concerns in the claims they reviewed, with approximately 33% of the audits resulting in “disagree” findings.

The concerns centered primarily around disagreements between procedure codes and diagnoses:

  • Focusing on denial trends, bundling was the top category for both inpatient and outpatient charge denials – the latter of which had an average value of $585 for each denied claim. The top reason was that the benefit had been included in a previously adjudicated service or procedure. Professional services had a first-time denial rate of 15%, led by claim submission/billing errors and carrying an average value of $283 each, while COVID-19 claims continue to attract higher denial rates from both commercial and federal payers.
  • 40% of COVID-19-related charges were denied and 40% of professional outpatient audits for COVID-19 and 20% of hospital inpatient audits failed.
  • Undercoding poses a significant revenue risk, with audits indicating the average value of underpayment is $3,200 for a hospital claim and $64 for a professional claim.
  • Overcoding remains problematic, with Medicare Advantage plans and payers under scrutiny for expensive inpatient medical necessity claims, drug charges, and clinical documentation to justify the final reimbursement.
  • Missing modifiers resulted in an average denied amount of $900 for hospital outpatient claims, $690 for inpatient claims, and $170 for professional claims.
  • 33% of charges submitted with hierarchical condition category (HCC) codes were initially denied by payers, highlighting increased scrutiny of complex inpatient stays and higher financial risk exposure to hospitals.

Healthcare Auditing and Revenue Integrity: 2021 Benchmarking and Trends Report is based on current charge and remit data from MDaudit Enterprise customers, including charges and denials sent to all payer types. The report includes more than 900 facilities, 50,000 providers, 1,500 coders and 700 auditors from U.S.-based acute care and children’s hospitals, academic medical centers, healthcare systems, and single and multi-specialty physician groups.
