Illinois law (Hospital Uninsured Patient Discount Act, 210 ILCS 89): an uninsured Illinois resident with family income up to 600% of the federal poverty level (300% at rural and critical access hospitals) can apply for a discount that brings the bill down to about 135% of the hospital's cost; up to 200% (125% at rural hospitals) medically necessary care is free. A hospital may collect no more than 25% of family income in 12 months. Ask the billing office for the application. Other states' laws.

Endoscopic sinus surgery opens blocked sinuses through the nose, without cuts on the face. It is same-day surgery for long-lasting sinusitis or polyps. Each sinus opened is billed with its own code, so the total depends on how many sinuses are treated.

Paying cash: what to do

  • Ask for a bundled self-pay price that includes the surgeon, anesthesia, facility and follow-up visits; hospital file prices usually cover only the facility.
  • Ask for the price of the whole operation, since several sinus codes are usually billed together.
  • Ask whether image guidance and a CT scan are included.
