Which block indicates whether the provider accepts assignment?

• A. Block 25
• B. Block 26
• C. Block 27
• D. Block 28

Answer: (C)

Block 27 on the CMS-1500 form specifically indicates whether the provider accepts assignment of benefits. When a provider accepts assignment, they are agreeing to accept the payment from the insurance company as payment in full for the services provided, rather than billing the patient for the difference. This block is essential for the claims process, as it affects how the insurer processes the claim and how much the patient may be responsible for out of pocket.

Block 25, on the other hand, provides the provider's federal tax identification number, and Block 26 is used to show the patient's signature on file. Block 28 is where the total charges for the services are recorded. None of these blocks directly address the acceptance of assignment, making Block 27 the only appropriate choice for indicating the provider's acceptance of assignment.
