Which is entered in Block 11c of the CMS-1500?

Block 11c of the CMS-1500 form is specifically designed to capture information about the policyholder's insurance coverage, particularly the commercial health insurance plan utilized. This block is where the name of the health insurance company or the specific health plan under which the patient is covered is entered. This information is crucial for claims processing as it allows the payer to identify the appropriate provider network and reimbursement policies associated with that specific plan.

The options provided include various types of information that might be relevant for processing claims, but only the name of the commercial health insurance plan directly corresponds to the information required in Block 11c. This ensures that the claim is reviewed under the correct plan parameters and coverage terms, facilitating efficient processing and reducing the likelihood of claim denials related to plan inadequacies or mismatches.

Other elements, like secondary insurance coverage, policyholder's commercial group number, and policyholder's gender and birth date, pertain to different blocks on the CMS-1500 form and serve different functions in establishing patient identification, coverage details, and claim validity. Each block of the form has a specific purpose, and ensuring that the correct information is entered in Block 11c is essential for the billing process to be carried out smoothly.
