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.
