Health care service plans and health insurance: third-party payments – This bill would require a health care service plan or an insurer that provides a policy of health insurance to accept payments from specified third-party entities, including an Indian tribe or a local, state, or federal government program. The bill would also require a financially interested entity, as defined, other than those entities, that is making a third-party premium payment to provide that assistance in a specified manner and to perform other related duties, including disclosing to the plan or the insurer the name of the enrollee or insured, as applicable, for each plan or policy on whose behalf a third-party premium payment will be made. The bill would require each plan or insurer to provide to the appropriate department information regarding premium payments by financially interested entities and reimbursement for services to providers, and would set forth standards governing the reimbursement of financially interested providers, including, but not limited to, chronic dialysis clinics, that meet certain criteria. Commencing January 1, 2022, the bill would require reimbursement to contracted providers to be the higher of the Medicare reimbursement rate or the rate determined pursuant to an independent dispute resolution process, as established by the bill, if either party seeks a rate determination pursuant to that process, and would require reimbursement for noncontracted providers to be governed by the terms and conditions of the health care service plan contract or health insurance policy, or the rate determined pursuant to the dispute resolution process, as prescribed. The reimbursement rates and dispute resolution process established by the bill would not apply to reimbursement for an enrollee or insured on behalf of whom a financially interested provider was already making premium payments to a health care service plan or insurer on or before October 1, 2019, except under specified circumstances. The bill would not alter existing obligations and requirements applicable to a health care service plan or health insurer relating to offering, marketing, selling, and issuing a health benefit plan, and cancellation or nonrenewal, as specified.
