Article 32 - (3201 - 3239) INSURANCE CONTRACTS - LIFE, ACCIDENT AND HEALTH, ANNUITIES
3224-C - Coordination of benefits.

§  3224-c.  Coordination  of  benefits.  An insurer or organization or
  corporation licensed or certified pursuant  to  article  forty-three  or
  forty-seven  of  this chapter or article forty-four of the public health
  law shall not deny a claim, either in whole or in  part,  on  the  basis
  that  it is coordinating benefits and another insurer or organization or
  corporation or other entity is liable for  the  payment  of  the  claim,
  unless  it  has a reasonable basis to believe that the insured has other
  health insurance coverage which is  primary  for  that  benefit.  If  an
  insurer or organization or corporation does not have current information
  from the insured regarding other coverage, and requests such information
  in  accordance with subsection (b) of section three thousand two hundred
  twenty-four-a of this article, and no  information  is  received  within
  forty-five  days,  the claim shall be adjudicated provided, however, the
  claim shall not be denied based  on  the  insurer,  or  organization  or
  corporation not having received such information.
