N.Y. Comp. Codes R. & Regs. tit. 23, § 400.5
(a) Upon receipt of a claim for emergency services, including inpatient services that follow an emergency room visit, rendered by a non-participating physician or a non-participating hospital, a health care plan shall:
(ii) in disputes involving a non-participating hospital that had previously entered into a participating provider agreement with the health care plan, pay the claim, within the timeframes established in Insurance Law section 3224-a, in an initial amount that is at least 25 percent greater than the amount the health care plan would have paid for the claim had the hospital been in-network, based on the most recent participating provider agreement between the health care plan and the non-participating hospital, except for the insured’s co-payment, coinsurance or deductible, if any. In the event the prior participating provider agreement between the health care plan and the non-participating hospital expired more than 12 months prior to the payment of the disputed claim, the payment amount shall be adjusted based upon the annual medical consumer price index, compounded for each year subsequent to the year the contract terminated up until the year the claim is paid. If a health care plan believes that this initial payment amount to a non-participating hospital with which it had previously entered into a participating provider agreement is not reasonable, it may submit a dispute to the superintendent for review by an IDRE, as provided in section 400.7 of this Part, and propose an amount it deems reasonable, provided that the health care plan:
(3) if the health care plan pays an amount less than the non-participating physician’s or non-participating hospital’s charge, provide the insured with notice, included on or in conjunction with, an explanation of benefits, which shall:
(1)
(b) Upon receipt of a claim for a surprise bill that is submitted with an assignment of benefits form, or that the health care plan otherwise determines is a surprise bill, the health care plan shall:
(3) Provide the insured with notice, included on or in conjunction with, an explanation of benefits, which shall:
(c) Upon receipt of a claim for the services of a non-participating physician or a non-participating referred health care provider that could be a surprise bill and that is not submitted with an assignment of benefits form, the health care plan shall provide the insured with notice, included on or in conjunction with, an explanation of benefits, which shall:
(e) If the health care plan receives a claim for services of a non-participating health care provider that is not submitted with an assignment of benefits form and pays the claim, the health care plan shall, upon receipt of the assignment of benefits form, determine whether it will attempt to negotiate additional reimbursement with the non-participating physician or non-participating referred health care provider. After receipt of the assignment of benefits form, if the health care plan attempts to negotiate additional reimbursement for the surprise bill and the attempts do not result in a resolution of the payment dispute or the health care plan does not attempt to negotiate the additional reimbursement for the surprise bill, the health care plan shall:
(2) Provide the insured with notice that shall:
(f) A health care plan shall prominently post on its website the information in paragraphs (1)-(5) of this subdivision and include in disclosure materials provided to insureds pursuant to Insurance Law sections 3217-a(a), 4324(a) and Public Health Law section 4408(1) the information in paragraphs (1)-(4) of this subdivision, as follows:
(h) A health care plan shall ensure that the insured shall incur no greater out-of-pocket costs for the services than the insured would have incurred with a participating physician, participating hospital, or participating health care provider:
(k) A health care plan shall designate, and inform the superintendent of, at least one officer and one staff member knowledgeable about the independent dispute resolution process who shall be responsible for oversight of the health care plan’s compliance with the independent dispute resolution process. The health care plan shall make at least one staff person available during normal business hours for not less than 40 hours per week. The health care plan shall respond to all inquiries from the superintendent relating to the dispute resolution process within three business days.
