Answer 1

In Block 25 of the CMS-1500 form, enter a hyphen after the first two digits of the provider's EIN for proper formatting.

Step-by-step explanation:

When Block 25 of the CMS-1500 contains the provider's EIN, you should enter a hyphen after the first two digits of the EIN. Block 25 is specifically used for the provider's Tax Identification Number (TIN) which can be an Employer Identification Number (EIN) or a Social Security Number (SSN). Proper formatting of the EIN with a hyphen helps ensure accurate processing of healthcare claims.
