In the world of healthcare, correct paperwork can be just as important as proper treatment. One term that often confuses both patients and providers is authorization. So, what is authorization in medical billing?
Authorization, also known as prior authorization or pre-certification, is the process of getting approval from a health insurance company before providing certain medical services. Without it, insurance may deny payment—even if the service was medically necessary.
🏥 What is Authorization in Medical Billing?
In simple terms, authorization in medical billing refers to the pre-approval from an insurance provider that confirms a medical procedure, test, or service is covered and medically necessary.
It is a critical step in the billing process to avoid claim denials and out-of-pocket surprises for patients.
