About Emergency billing
Emergency room visits are among the most overcharged medical services in the U.S. ER billing combines a physician E&M code with a hospital facility fee — and the facility fee alone can run $500 to $3,000.
Request the itemized bill (UB-04) and the ED physician's documentation. If the medical decision-making does not support the billed level, demand a downcode. Out-of-network ER billing above in-network rates is illegal under the No Surprises Act.
How to dispute a CPT 99292 overcharge
- Request the itemized bill. You are entitled to a detailed line-by-line bill showing every CPT code billed. Ask in writing.
- Compare to Medicare allowable. If the charge exceeds 150% of Medicare ($338), you have grounds to dispute.
- Request documentation. For E&M codes, ask for the visit note. For procedures, ask for the operative report. The documentation must justify the code billed.
- Send a formal dispute letter. Cite the specific discrepancy between the documentation and the code. Reference Medicare rates and NCCI edits where applicable.
- Follow up in writing. Give the provider 30 days to respond. If they don't, escalate to the state attorney general and insurance commissioner.
