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.
A sleep study records breathing, oxygen and other signals overnight to diagnose sleep apnea and other sleep disorders. The biggest price difference is where it is done: an in-lab study at a sleep center with a technologist (95810, or 95811 when CPAP is started the same night) usually costs more than a home sleep apnea test (95806), which suits some patients but not all.

Paying cash: what to do
- Ask your clinician whether a home sleep apnea test is appropriate for you, since it is usually the less expensive first step.
- Ask whether the sleep physician's interpretation is included in the self-pay price or billed separately.
- If CPAP is prescribed, get self-pay prices for the machine and mask from medical equipment suppliers; they are not part of the study price.
