Emergency Room Bills and Facility Fees

The hospital bills for the room, nursing, equipment and supplies. The emergency physician — often an independent contractor group, not a hospital employee — bills separately for their professional service. Radiologists, pathologists and consulting specialists each bill their own professional component too. Different tax IDs, different claims, different appeal processes.

Getting several bills for one visit is normal. Getting several bills for the same service is a duplicate — check dates, codes and amounts across all of them.

Emergency departments bill an evaluation and management facility charge coded 99281–99285, level 1 (minor) through level 5 (high complexity), plus 99291 for critical care. Under Medicare's outpatient system these map to Ambulatory Payment Classifications; commercial charges are set from the hospital's own chargemaster and are typically many times the Medicare rate.^[3]

Level is driven by resource intensity — monitoring, interventions, staff time — not by how sick you felt. A visit that involved a brief exam and a prescription should not be coded level 5. Upcoding the level is one of the most common ER billing errors, and it is visible only on an itemized bill.

Separate charges usually stack on top: imaging, labs, IV administration and infusion time, medications, observation hours, and supplies.

Insurers may not deny emergency coverage merely because the final diagnosis turned out to be minor. The test is whether a prudent layperson with average knowledge of health and medicine would have believed the symptoms required emergency care — chest pain that turns out to be reflux is still covered emergency care.^[2] If a denial cites the final diagnosis, quote this standard in the appeal.

Separately, EMTALA requires hospitals with emergency departments to provide a medical screening examination and stabilizing treatment regardless of ability to pay or insurance status. It guarantees treatment, not free treatment — but a demand for payment before screening is a violation.^[1]

Emergency services are protected from balance billing whether the hospital or the treating clinicians are in-network or not, including post-stabilization care until you can safely be transferred. Your cost sharing must be calculated at in-network rates and counted toward your in-network deductible and out-of-pocket maximum.^[2] Air ambulance is covered by the ban; ground ambulance generally is not.

A freestanding emergency department looks like an urgent care clinic and bills like a hospital: facility fee plus physician fee, often for a complaint that urgent care would have handled for a fraction of the cost. Check signage and paperwork for the words "emergency" and "facility fee," and ask before registration if the situation isn't urgent.

When a hospital system buys a physician practice, the same visit in the same building can acquire a facility fee on top of the doctor's charge. Hospitals must publish a machine-readable file and a consumer-friendly display of standard charges, which you can use to check the fee in advance.^[4] Some states also require advance written notice of facility fees at off-campus locations.

1. Request the fully itemized bill with CPT, revenue and HCPCS codes.
2. Compare it to the EOB — the provider bill must not exceed the patient responsibility shown.
3. Check the E/M level against what actually happened; ask for the coding rationale.
4. Look for duplicate labs, supplies billed twice, and charges after discharge time.
5. Verify observation hours against your actual arrival and departure times.
6. If insurance denied on diagnosis, appeal citing the prudent layperson standard.
7. If a balance bill appears for out-of-network clinicians, cite the No Surprises Act and report it.
8. Apply for hospital financial assistance in parallel — nonprofit hospitals must have a policy.
