What are common reasons for duplicate claims, and how can they be prevented?

• A. Submitting the same service multiple times; prevent by using claim control numbers, clearinghouse validations, and denial/void checks.
• B. Submitting different services with similar dates to trick the payer.
• C. Waiting for denial notices before resubmitting the same claim.
• D. Not using any claim control numbers.

Answer: (A)

Duplicates happen when the same service is submitted more than once, which can confuse payers, delay payments, and risk overpaying. The best safeguard is using a claim control number as a unique reference for each claim so the system can recognize and block a second submission of the same claim. Clearinghouse validations add another layer by checking for duplicates during transmission, flagging them before they reach the payer. Denial and void checks further prevent resubmitting claims that have already been denied or voided, ensuring you only correct and resubmit when appropriate. Together, these controls detect and stop duplicates at multiple points in the process, keeping submission history clean.
