Block 20: If lab tests were performed by an entity other than the billing entity, what should you mark?

• A. Yes
• B. No
• C. Not applicable
• D. Unknown

Answer: (A)

When a lab test is performed by a facility other than the billing entity, you mark Yes. This signals to the payer that outsourcing occurred, which typically means the outside lab will bill for the test and the claim needs to include the external lab’s information so the correct party can be reimbursed. It also helps ensure that the claim routing and any required reporting (such as the performing lab’s details) are handled properly. If the billing entity itself performed the lab work, you would not mark Yes; you’d indicate the opposite. Not applicable would be incorrect here because the situation clearly involves an outside lab, and Unknown isn’t appropriate when you know the test was done by a different entity.
