Denial of the entire claim is considered a claim-level denial. For many hospitals, this type of problem accounts for the majority of Medicare and Medicaid denials and typically results from inaccuracies related to patient registration, late-charge management, duplicate billing, production of medical information for external review, and/or physicians’ ordering practices. Common denial types include the following:

> The patient was not identified as insured
> The claim submitted was a duplicate
> The services were deemed by the payer as not medically necessary
> The charges for outpatient services were in proximity to inpatient services
> The patient’s date of death preceded the date of service
