2 Colo. Code Regs. § 505-1-21.840
Insurance and other benefits shall be applied first to the cost of care. Insurance and other benefits for any patient shall be billed at the cost of care. A legally responsible person who fails to cooperate in making existing insurance and other benefits available for payment will nevertheless be considered as having benefits available for payment.
The ability to pay shall be calculated taking into consideration the factors in Section 27-92-104, C.R.S., and using the schedule in Section 21.860 of these rules and regulations.
The adjusted charge shall be the balance of the cost of care after insurance and other benefits have been deducted, or the ability to pay, whichever is less. If the legally responsible person(s) does not cooperate in making insurance and other benefits available, the legally responsible person(s) will be billed for the amount equal to the dollar value of the insurance or benefits in addition to the lesser of the balance of the cost of care or the ability to pay. If the dollar value of insurance and other benefits cannot be determined, the legally responsible person(s) will be billed the full cost of care.
A legally responsible person whose income is substantially reduced as a result of changed financial circumstances after the ability to pay has been determined, may request a redetermination and provide the hospital with evidence of financial change so that a new ability to pay may be determined based on current income and assets. Should there be an increase in income, assets, insurance or other benefits, this information must be reported to the institution within sixty (60) calendar days of the changed financial circumstances so that an appropriate redetermination of the ability to pay can be made.
