Why Are Hospital Bills So Expensive?

The Chargemaster: The Root of the Problem

Every hospital maintains a document called the chargemaster — a master price list for every service, supply, and procedure they provide. These prices are often 2 to 10 times higher than what Medicare pays for the same service, and they bear little relationship to actual costs.

The chargemaster exists as a starting point for negotiations with insurance companies. Insurers negotiate discounts off the chargemaster rate — so a hospital might charge $10,000 for a procedure, an insurer negotiates it down to $4,000, and that's what gets paid. Uninsured patients, however, often get billed the full chargemaster rate.

Why Nobody Actually Pays the Sticker Price

Medicare patients

Medicare sets its own payment rates — typically the lowest of any payer — and hospitals are required to accept them for Medicare patients.

Medicaid patients

Similar to Medicare but rates vary by state. Generally even lower than Medicare rates.

Insured patients

Your insurer has negotiated a contracted rate with the hospital, which is significantly below the chargemaster price. You pay your deductible, copay, or coinsurance based on this negotiated rate.

Uninsured patients

Often billed at or near the full chargemaster rate — the highest price of any group. This is why the uninsured often face the most catastrophic medical bills. However, hospitals are required to offer charity care and most will negotiate.

The Specific Things That Inflate Your Bill

Facility fees

Hospitals charge a "facility fee" just for using the building — separate from what your doctor charges. These can add hundreds or thousands to a bill for a procedure that might be much cheaper at a standalone clinic.

Supply markups

Hospitals routinely charge 100-500% markups on supplies. A saline bag that costs $1 wholesale may be billed at $100-300. These charges are rarely questioned because patients don't know what they should cost.

Upcoding

Billing for a more expensive procedure or visit level than what was actually performed. A routine ER visit coded as a complex one can cost thousands more.

Unbundling

Breaking a procedure into individual components to charge for each separately, when they should be billed together at a lower bundled rate.

Administrative overhead

The US healthcare system has enormous administrative complexity. Hospitals employ large billing departments just to navigate insurance systems — costs that ultimately get passed to patients.

What Medicare Pays vs. What You're Charged

Medicare publishes its payment rates publicly — and the difference between Medicare rates and hospital chargemaster prices is striking. A hospital might bill $2,500 for a basic ER visit that Medicare reimburses at $800. A CT scan billed at $4,000 might have a Medicare rate of $400-600.

Medicare rates represent what the federal government considers a fair payment for each service. Any charge significantly above Medicare rates — generally more than 2-3x — is worth questioning.

What You Can Do About It

You can't change the system, but you can protect yourself:

Always request an itemized bill — summary bills hide overcharges

Compare your charges to Medicare rates using BillScan AI or the CMS website

Ask about financial assistance before paying anything

Dispute errors in writing — most overcharges go uncontested because patients don't know they can fight back
