What does 'scrubber' refer to in the context of claims processing?

In the context of claims processing, a 'scrubber' refers to a software application designed to check and validate medical claims for coding errors before they are submitted to insurance payers. The primary function of a scrubber is to ensure that the claims are compliant with coding standards, billing guidelines, and payer-specific regulations. By identifying potential issues such as incorrect procedure codes, diagnosis codes, or missing information, the scrubber helps healthcare providers reduce claim rejections and denials, thereby improving the revenue cycle. This quality control step is essential for ensuring accurate and timely reimbursement.

The other options do not align with the specific role that a scrubber plays in claims processing. A tool that manages patient access focuses on patient interactions and registration rather than claim accuracy. A document that outlines insurance policy refers to the terms and conditions of coverage rather than to processing claims, and a payment processing system deals with the collection and payment of claims rather than pre-submission validation.
