# [How to negotiate an ER bill \(facility fees and level upcoding\)](https://trymumm.com/guides/er-bill-negotiation) > Separate the hospital’s facility charges from the clinician’s bill. Request itemized statements, compare them with the insurance explanation of benefits and ask the provider to explain charges or visit levels you dispute. Then discuss assistance or payment terms for the remaining balance. - **Updated:** 2026-07-20 - **Category:** Medical Bills - **Read time:** 8 min ## The level decides the bill Ask the hospital to explain its facility charge and how it selected the billed level. Compare the statement with your visit records and insurer’s explanation of benefits. If the explanation leaves a discrepancy, request review by the billing or coding team. ## Request a billing review with the supporting clinical record Ask the billing office which records support the billed visit level and request a coding review if the charges appear inconsistent with the care received. Facility and professional billing can use different rules. Ask the provider’s coding team to explain the basis rather than assigning a visit level yourself. ## The rest of the itemized bill Compare laboratory, imaging, supplies and observation charges with your records. Separate professional and facility bills before flagging duplicates. Ask your insurer how any correction changes your patient responsibility. ## Settle the corrected total After the provider reviews the charges, request its financial-assistance policy and discuss payment options for the corrected balance. Get the full amount, installment schedule and any fees in writing. ## Questions people actually ask ## What is a facility fee, and why is it half my ER bill? The facility fee covers hospital resources associated with the visit and is separate from professional charges. Ask the hospital for its breakdown and explanation of the billed level. Review both bills and the insurance adjustments together. ## How do I prove the ER upcoded my visit? Request the clinical documentation and the provider’s explanation of the billed code. Ask its coding team to review the charge against the applicable criteria and send a corrected claim if a change is warranted. Keep the response with your bill and insurance records. ## Can I negotiate the ER doctor's separate bill too? Yes — the physician group (often a separate company like an emergency medicine staffing firm) bills independently and negotiates independently. If the group is out-of-network at an in-network ER, the No Surprises Act likely caps your cost at in-network rates — cite it. Otherwise the same settlement playbook applies. ## What if I left without being seen and got billed anyway? Ask for the registration, triage and service records supporting the charge. Explain when you left and request billing review of any service you believe was not provided. Keep the written response. ## Related - [How to negotiate a medical bill \(the actual playbook\)](https://trymumm.com/guides/how-to-negotiate-a-medical-bill) - [How to request an itemized medical bill \(and read it\)](https://trymumm.com/guides/itemized-bill-request) - [How to negotiate an ambulance bill](https://trymumm.com/guides/ambulance-bill-negotiation)
