Billing has indicated that they are receiving rejections (OCE edit 28) on Medicare vaccination claims. As the new physician practice manager, you have decided to review the chargemaster for influenza, pneumonia, and hepatitis B vaccination charges to identify the issue(s), since these claims would be hard-coded. The practice sees only adult patients, with a significant portion of them having Medicare as their payer, so it is important to resolve the error(s) quickly.
