Section 210-61-007 - Standards for the prompt investigation of claims007.01 Every insurer shall, within fifteen (15) days of receipt of proof of loss from a claimant, initiate investigation of the claim.007.02 The insurer's standards for claims processing shall be such that notice of claim or proof of loss submitted against one policy issued by that insurer shall fulfill the insured's obligation under any and all similar policies issued by that insurer and specifically identified by the insured to the insurer to the same degree that the same form would be required under any similar policy. If additional information is required to fulfill the insured's obligation under similar policies, the insurer may request the additional information. When it is apparent to the insurer that additional benefits would be payable under an insured's policy upon additional proofs of loss, the insurer shall communicate to and cooperate with the insured in determining the extent of the insurer's additional liability.210 Neb.
