Good afternoon Bover,
I sorry I could not find a more definitive but under the BLR's state by state comparison for "Mandated Insurance" I found under NY the following:
Dependent coverage mandates:
Newborns covered at birth including premature birth, congenital defects, and birth abnormalities. Adoptees covered from time employee takes custody. Handicapped dependents covered regardless of age. One year of coverage for college student on medical leave of absence who would otherwise lose coverage solely because he or she is not attending school.
Citation: McKinney’s Consol. Laws Ins. Law § 4305(c)(1), § 3237.
Discrimination on basis of DES exposure.
Citation: McKinney’s Consol. Laws Ins. Law § 3225.
Miscellaneous benefit requirements:
Managed care plans must cover chiropractor care. No financial penalties for second opinions from out-of-network specialists referred by attending physician. Internal and external appeal of benefits denied for lack of medical necessity. Insurers issuing small employer health insurance plans covering from two to 50 employees must use “community rating” when setting premiums; once accepted for coverage, a small employer group may not be terminated by the insurer due to claims experience.
Citation: McKinney’s Consol. Laws Ins. Law § 3221(k)(9), § 3221(k)911), § 4900 et seq., § 3231 et seq.
Additionally, in another source I have which is a 2013 HR Law Guide (hardcopy) that I have from a publisher by the name of "Wolters Kluwer" (this reference is so big you could park one of those Smart cars on it) provided the following - maybe related information:
In March 2005, a New York appellate court struck down a New York City ordinance that would have required city contractors to provide domestic partner benefits to their employees to the same extent they provide spousal benefits. The court found that the ordinance violated state law because it excluded a class of bidders for reasons unrelated to price or quality of the goods or services to be provided. The court also found that the ordinance violated ERISA.
The Human Rights Campaign organization might be a good group to get in contact with for more information (other than going to an attorney - like me you probably don't have in house counsel to run this question by). Here is a link to this group http://www.hrc.org/files/assets/resources/Employment_Laws_and_Policies.pdf
Good luck! Tom
