Incorrect medical bills can negatively impact both personal finances and health. Reviewing explanation of benefits statements and medical bills is important to check for errors in charges, diagnoses, or procedure codes which could lead to unnecessary costs or improper treatment over time. Small errors in bills may accumulate and eventually exceed lifetime maximums for insurance coverage. Additionally, rising healthcare costs that result from erroneous billing affect insurance premiums for everyone. It is advised to carefully review all medical documentation received and seek help from insurance plans or billing experts if unable to resolve any identified errors or anomalies.
