Emergency Room Cost Calculator
Estimate Emergency Department visits based on triage acuity level (Level 1–5), attending physician fees, CT imaging, laboratory panels, and ER insurance copays.
Calculation Summary
Emergency Department Cost Model
Total ER Bill = Facility Base Fee (Level 1–5) + ER Physician Fee + Diagnostic Scans + Lab Bloodwork + IV Therapy- Facility Acuity Fee: CPT codes 99281–99285 based on triage severity and complexity.
- Physician Professional Fee: The emergency medicine doctor’s examination charge.
- Diagnostic Testing: High-complexity CT scans, MRIs, X-rays, and blood work.
- Patient Cost Sharing: Fixed ER copay or deductible plus coinsurance.
Step-by-Step Worked Example
Calculation Steps:
- Total Gross ER Charges = $1,400 + $450 + $850 + $320 + $280 = $3,300.
- Patient Copay = $250.
- Remaining Balance = $3,300 - $250 = $3,050.
- Coinsurance on Balance = $3,050 × 20% = $610.
- Total Patient ER Cost = $250 + $610 = $860.
- Insurance Payment = $3,300 - $860 = $2,440.
