What does a rejected claim labeled "invalid birth date" usually indicate?

A claim labeled "invalid birth date" typically indicates that the birth date provided in the claim does not correspond with the records maintained by the insurance company. This mismatch can occur for several reasons: for instance, the insurance company may have different information recorded for the patient, or there may have been an error in entering the birth date during the claim submission process. These discrepancies can lead to the rejection of the claim until the data is corrected and verified. Thus, ensuring that patient information is accurately recorded and aligns with the insurer's records is crucial for smooth processing of claims in a pharmacy setting.
