Understanding and Preventing Claim Denials: A Strategic Approach

Claim denials are a persistent challenge for inpatient facilities, leading to financial strain, administrative burdens, and potential disruptions in patient care. Effective claim denial management starts with understanding why claims are denied, so facilities can minimize risk, maximize reimbursement, and implement proactive prevention strategies.

Top Reasons for Inpatient Claim Denials

• Medical Necessity & Documentation Gaps
• Payers often deny claims due to insufficient documentation supporting medical necessity. Common issues include:
• Lack of proper utilization review and initial screening tools
• Incorrect patient status (inpatient vs. observation)
• Lack of detailed physician notes justifying inpatient admission
• Missing physician adviser peer to peer reviews
• No appeal completed for authorization denials

• DRG Coding Downgrades
• Lack of clinical validation in complications or comorbidities (CC or MCC)
• Improper coding and procedure codes can trigger denials.
• Lack of response to record submission request
• Technical & Administrative Errors
• Missing or late submission of prior authorization requests
• Clinical Information not provided
• Data entry mistakes in patient demographics or insurance details
• Readmissions Denials
• Commercial, Medicare and Medicaid managed products misinterpretation of readmission policy and procedures
• Medicare and Commercial Payers Regularly Update Policies
• This leads to inconsistent compliance if facilities do not stay current. Common pitfalls include:
• 2 Midnight Rule
• Short Stay policies inconsistent with Medicare Regulations

As a leading denials management provider, McBee has reviewed hundreds of thousands of appeals and categorized the most common denial reasons. McBee classifies our appeals into “Inpatient” and “DRG Downgrade” categories to better identify root causes and provide meaningful feedback to our clients. The root causes of our Inpatient denials are 84% medical necessity related, 12% technical issues and 4 % readmissions. The breakdown of our most common inpatient denial reasons are illustrated in the graph below.

DRG-challenged denials are 69% clinical validation related. An insurance company uses their own references or guidance to suggest a diagnosis code was misused by the treating physician. 10% of DRG downgrades we have encountered are solely coding related and 3% are lack of records submitted for audit purposes.  The breakdown of our most common DRG Downgrade denial reasons are illustrated in the graph below.
