Common Questions.

What exactly is an itemized bill?

An itemized bill is a detailed statement from your healthcare provider that lists every single charge, procedure, and supply used during your visit. Most importantly, it includes medical codes like CPT®, HCPCS, or DRG codes. This is different from a "summary bill" which just shows a single total.

How do I get an itemized bill if I only have a summary?

You have a legal right to an itemized bill under HIPAA. Simply call your provider's billing department and say: "I am requesting a fully itemized statement with CPT® and HCPCS codes for my recent visit." They are required to provide it to you.

Which types of medical bills do you support?

We currently support ER visits, hospital stays (inpatient and outpatient), lab work, imaging (X-rays, MRIs), and clinic visits. We do not yet support ambulance, eye, dental, or psychiatric facility bills.

Can Bill Sherlock review an ER bill?

Yes. Upload your itemized ER bill or emergency room bill, and Bill Sherlock checks the charges, billing codes, and pricing benchmarks for possible overcharges or billing mistakes.

Can this help me negotiate a hospital bill?

Yes. The report gives you pricing comparisons, billing red flags, and plain-language questions you can use when calling the hospital billing department, disputing a charge, or trying to negotiate a hospital bill.

Why was my ER visit cost so high?

ER visit costs often include facility fees, provider charges, labs, imaging, medications, and supplies. An itemized bill helps show what you were actually charged for and whether any line items deserve a closer look.

How much can I realistically save?

While every case is different, many users find overcharges ranging from $200 to $2,000. For major hospital stays, errors can sometimes reach into the tens of thousands. Our goal is to ensure you only pay the fair, market-standard rate.

Is my data sold to insurance companies?

No. Never. We are a patient-advocacy tool. We do not share your individual data with insurers, hospitals, or marketers. We only use anonymized, aggregated data to help other patients see what "fair prices" look like in their area.
