What is the primary role of a clearinghouse in medical billing?

• A. It transmits claims electronically between the healthcare facility and the health insurance company.
• B. It stores patient medical records.
• C. It schedules patient appointments.
• D. It audits provider billing practices.

Answer: (B)

The main function of a medical billing clearinghouse is to act as an intermediary that receives claims from a provider’s system, checks them for errors, formats them to each payer’s specifications, and forwards them to the appropriate insurance company. It helps catch missing or incorrect data, invalid codes, and formatting issues before submission, and it can return error reports and manage resubmissions. It doesn’t store patient medical records, schedule appointments, or conduct billing audits—those tasks are handled by the EHR/storage system, scheduling tools, and internal auditing/compliance processes.
