What information is contained in Block 1 of the CMS-1500 form?

1. Patient payment history

2. Type of insurance plan

3. Claim adjustments

4. Medical diagnosis codes

The correct answer is: Type of insurance plan

Block 1 of the CMS-1500 form is specifically designated for the type of insurance plan of the patient. This section allows the provider to indicate whether the claim is being submitted to commercial insurance, Medicare, Medicaid, or another type of payer. By including this information, it helps to ensure that the claim is processed accurately and efficiently by the insurance company, aligning the billing with the specific requirements of the payer identified. The other options do not accurately reflect the contents of Block 1. Patient payment history is recorded elsewhere in the documentation. Claim adjustments occur after initial processing, while medical diagnosis codes are reported in different sections of the form specifically designed to reflect the patient's medical conditions and the services provided.
