What is a hospital chargemaster?

A chargemaster (charge description master) is the official list of prices a hospital charges for every service, supply, and medication. These prices are typically 3–10× higher than what Medicare pays and bear little relation to actual costs.

Why does a Tylenol cost $50 at the hospital?

Hospitals set chargemaster prices to maximize reimbursement from insurers, who then negotiate discounts. The problem: uninsured patients and high-deductible patients are often billed at chargemaster rates — the highest possible price.

Can I dispute a chargemaster charge?

Yes. Ask for an itemized bill and compare each charge to Medicare reference rates (available on BillKarma). Any charge over 3× the Medicare rate is worth formally disputing. Most hospitals will reduce on request.

The saline scandal: A standard $1 bag of saline solution costs hospitals roughly $1 to produce. Patients are routinely billed $500–$1,500. This is legal. The uninsured and anyone on a high-deductible plan often pay these chargemaster rates in full — the highest prices charged to anyone, with no negotiated discount.

How to fight back

Request an itemized bill

Every patient has the right to an itemized bill listing every charge by code and description. Hospitals are required to provide it. Call billing and ask for it in writing.

Compare to Medicare rates

Look up each CPT code in BillKarma's database. Any charge above 3× the Medicare rate is a legitimate dispute target. Most hospitals will negotiate down without litigation.

Send a formal dispute letter

BillKarma generates a free dispute letter referencing federal pricing benchmarks. Hospitals reduce or waive charges far more often than patients realize — but only when asked.
