The three most common mistakes that cause medical claim denials are incorrect patient identification details, lack of prior authorization, and untimely filing. Statistics from 2026 indicate that these administrative errors account for nearly 65% to 75% of all rejected claims, directly impacting a practice’s cash flow and operational efficiency.
While these errors are common, they are also highly preventable. Many practices frequently ask, what are the two most common claim submission errors? The reality is that patient data inaccuracies and authorization oversight consistently top that list. At The Medicators, we provide a thorough practice analysis to audit your current workflows and eliminate these recurring bottlenecks before they reach the payer.
The Top 3 Claim Errors Explained
Most denials stem from these specific technical or administrative oversights:
- Inaccurate Patient Information: Simple clerical errors such as a misspelled name, an incorrect date of birth, or an outdated insurance ID number are the leading causes of “Member Not Found” denials.
- Missing Prior Authorization: Performing a procedure or prescribing a high-cost medication without first obtaining the required “OK” from the insurance company leads to immediate non-payment.
- Untimely Filing: Every insurance carrier has a specific “window” (often 90 to 180 days) in which a claim must be submitted. If the deadline is missed, the claim is automatically denied, regardless of medical necessity.
Other Frequent Factors in Claim Rejection
Beyond the top three, several other technical factors can lead to a loss of revenue:
- Coding Inaccuracies: Using non-specific ICD-10 codes or mismatched CPT codes that do not support the level of care provided.
- Electronic Transaction Flaws: Complex technical issues embedded within the electronic data interchange (EDI) exchange, such as a missing or improperly formatted 835 healthcare policy identification segment (specifically within loop 2110, the service payment information REF) if present, can cause immediate clearinghouse or payer rejection before adjudication even begins.
- Duplicate Claims: Resubmitting a claim for the same service before the first one has been fully processed by the insurer.
- Coordination of Benefits (COB) Issues: When a patient has multiple insurance plans and the primary payer has not been correctly identified.
