Section 83-9-13 - Waiver; proof-of-loss form; revision of form(1) The acknowledgment by any insurer of the receipt of notice given under any policy covered by Sections 83-9-1 through 83-9-21, or the furnishing of forms for filing proofs of loss, or the acceptance of such proofs, or the investigation of any claim thereunder, shall not operate as a waiver of any of the rights of the insurer in defense of any claim arising under such policy.(2) The Commissioner of Insurance shall prescribe the use of the National Uniform Bill-82 (UB-82) and the Health Care Financing Administration (HCFA) Form 1500 as the uniform proof of loss forms. After July 1, 1985, no insurance company writing policies of accident and sickness insurance may require proof of loss to be on any claim form but the UB-82 or HCFA Form 1500, whichever is appropriate for services rendered.(3) The Commissioner of Insurance shall review the uniform proof of loss forms prescribed under subsection (2), seek comments and suggestions from insurers and consumer groups about proposed improvements to the forms, and determine whether any revisions should be made to either form that would simplify or otherwise improve the form. If the commissioner determines that either form should be revised, he shall make the revisions to the form and prescribe the use of the revised form by all insurance companies writing policies of accident and sickness insurance in Mississippi. After six (6) months from the date that the commissioner has prescribed the use of any revised form, no insurance company writing policies of accident and sickness insurance may require proof of loss to be on any claim form but the revised form when that is the appropriate form for services rendered.Codes;, 1942, § 5687-06; Laws, 1956, ch. 330, § 6; Laws, 1971, ch. 419, § 1; Laws, 1974, ch. 397; Laws, 1985, ch. 370; Laws, 1993, ch. 336, § 1, eff. 7/1/1993.
