Using AI to Understand Medical Bills

A medical bill, an insurer’s explanation of benefits (EOB), and a Medicare Summary Notice (MSN) are different documents. CMS explains that an EOB summarizes claim processing, the service and date, allowed charges, insurer payment, and patient balance; it is not a bill. An MSN notifies Medicare beneficiaries about claim decisions. A provider bill is the request for payment. Confusing these documents can make a person think they owe the wrong amount or have missed an appeal deadline.

AI may extract line items from a photo, explain common terms, or help draft questions. Optical character recognition can confuse digits or service codes, and a language model may infer coverage or deadlines without knowing the exact plan, provider contract, or current rules. A generated answer cannot decide whether a charge is legally valid. Compare the dates and services, amounts already paid, insurer’s “what you owe” or patient-balance field, and the provider’s actual bill. If amounts do not align, call the plan or provider using the number on the statement.

Before using AI, remove account identifiers and unnecessary health information unless the service is approved for this data and purpose. Preserve the original documents and note reference numbers and call dates. Ask the insurer or provider to explain a code, denial, or discrepancy in writing. Check appeal instructions and filing dates on the official notice; do not rely on a chatbot’s deadline. AI can make the paperwork easier to navigate, but the plan, provider, and official notices determine the next steps.
