What does box 28 require on the CMS-1500 form?

Box 28 of the CMS-1500 form is specifically used to indicate the total amount billed by the healthcare provider for the services rendered. However, it is crucial to note that this box should reflect the amount after adjustments have been made based on contracts or agreements with the payer. This means that any contractual adjustments, such as discounts or negotiated rates, should be accounted for when entering the total in this box.

As a result, the correct interpretation of Box 28 is that it represents the amount billed after these reductions have been applied. This ensures that the insurance companies processing the claims understand the actual charge due to the agreements made with the provider, facilitating accurate payment processing and ensuring that the claims are managed in accordance with the provider's contract with the insurer.
