What type of information is captured in Part I of the CMS-1500 form?

• A. Demographic and policy information for patient and insured.
• B. Medical history and lab results.
• C. Facility equipment and room number.
• D. Provider's billing rates and codes.

Answer: (A)

Part I is where the claim gathers who is being treated and whose insurance is billed. It collects patient demographics—name, address, date of birth, gender—and the insured’s information, such as policy or group numbers and the insured’s relationship to the patient. This data is used to identify the patient in the payer’s system and to verify eligibility and coverage for processing the claim. Medical history, lab results, and other clinical data belong in the medical record and are not entered in this section. Details about facility equipment or room numbers are unrelated to the patient’s billing identity. Billing rates and codes appear later in the form, not in this section.
