US Medical Billing, Explained
In the US, a single visit can generate a hospital bill, separate physician bills, and an Explanation of Benefits from your insurer — none of which use the same numbers. These guides decode each document, show you how patient responsibility is calculated, and explain the federal protections you can use when something looks wrong.

What makes US billing different
- Multi-payer system. Employer plans, marketplace plans, Medicare, and Medicaid each have their own rules, networks, and appeal timelines.
- Chargemaster pricing. The billed amount is a list price. Insurers pay a contracted "allowed amount" that is often a fraction of it.
- Cost sharing. Deductible, copay, coinsurance, and out-of-pocket maximum decide what lands on you.
- CPT / HCPCS / ICD-10 coding. Nearly every dispute traces back to a code that doesn't match what happened.
- No Surprises Act (2022). Limits balance billing for most emergency care and out-of-network care at in-network facilities, and gives uninsured patients a right to a Good Faith Estimate.
- Appeals. You have a right to an internal appeal and, after that, an independent external review.
- Nonprofit hospital charity care. Federally required financial assistance policies, often covering households well above the poverty line.
