686B.4Asbestos claims involving nonmalignant conditions elements of proof.An asbestos action involving a nonmalignant condition shall not be brought or maintained in the absence of prima facie evidence that the exposed person has a physical impairment for which asbestos exposure was a substantial contributing factor. The prima facie showing shall be made as to each defendant and include a detailed narrative medical report and diagnosis signed under oath by a qualified physician that includes all of the following:1. Radiological or pathological evidence of asbestosis or radiological evidence of diffuse bilateral pleural thickening or a high-resolution computed tomography scan showing evidence of asbestosis or diffuse bilateral pleural thickening. 2. A detailed occupational and exposure history from the exposed person or, if that person is deceased, from the person most knowledgeable about the exposures that form the basis of the action, including identification of all of the exposed person’s principal places of employment and exposures to airborne contaminants and whether each place of employment involved exposures to airborne contaminants, including asbestos fibers or other disease-causing dusts or fumes, that may cause pulmonary impairment and the nature, duration, and level of any exposure. 3. A detailed medical, social, and smoking history from the exposed person or, if that person is deceased, from the person most knowledgeable, including a thorough review of the past and present medical problems of the exposed person and the most probable cause of such medical problems. 4. Evidence verifying that at least fifteen years have elapsed between the exposed person’s date of first exposure to asbestos and the date of diagnosis. 5. Evidence based upon a personal medical examination and pulmonary function testing of the exposed person or, if the exposed person is deceased, based upon the person’s medical records, that the exposed person has or the deceased person had a permanent respiratory impairment rating of at least class 2 as defined by and evaluated pursuant to the AMA guides or reported significant changes year to year in lung function for FVC, FEV1, or diffusing capacity of the lung for carbon monoxide as defined by the American thoracic society’s interpretative strategies for lung function tests, 26 European Respiratory Journal 948-68, 961-62, table 12 (2005), as updated. 6. Evidence that asbestosis or diffuse bilateral pleural thickening, rather than chronic obstructive pulmonary disease, is a substantial contributing factor to the exposed person’s physical impairment, based on a determination that the exposed person has any of the following: a. FVC below the predicted lower limit of normal and FEV1/FVC ratio, using actual values, at or above the predicted lower limit of normal. b. Total lung capacity, by plethysmography or timed gas dilution, below the predicted lower limit of normal. c. A chest X ray showing bilateral small, irregular opacities (s, t, or u) graded by a certified B-reader as at least 2/1 on the ILO scale. 7. The qualified physician signing the detailed narrative medical report has concluded that exposure to asbestos was a substantial contributing factor to the exposed person’s physical impairment and not more probably the result of other causes. An opinion that the medical findings and impairment are consistent with or compatible with exposure to asbestos, or similar opinion, does not satisfy the requirements of this subsection. 2017 Acts, ch 11, §13686B.5Silica claims involving silicosis elements of proof.A silica action involving silicosis shall not be brought or maintained in the absence of prima facie evidence that the exposed person has a physical impairment for which exposure to silica was a substantial contributing factor. The prima facie showing shall be made as to each defendant and include a detailed narrative medical report and diagnosis signed under oath by a qualified physician that includes all of the following:1. Radiological or pathological evidence of silicosis or a high-resolution computed tomography scan showing evidence of silicosis.2. A detailed occupational and exposure history from the exposed person or, if that person is deceased, from the person most knowledgeable about the exposures that form the basis of the action, including identification of all principal places of employment and exposures to airborne contaminants and whether each place of employment involved exposures to airborne contaminants, including silica or other disease-causing dusts or fumes, that may cause pulmonary impairment and the nature, duration, and level of any exposure.3. A detailed medical, social, and smoking history from the exposed person or, if that person is deceased, from the person most knowledgeable, including a thorough review of the past and present medical problems of the exposed person and the most probable cause of such medical problems.4. Evidence that a sufficient latency period has elapsed between the exposed person’s date of first exposure to silica and the day of diagnosis.5. Evidence based upon a personal medical examination and pulmonary function testing of the exposed person or, if the exposed person is deceased, based upon the person’s medical records, that the exposed person has or the deceased person had a permanent respiratory impairment rating of at least class 2 as defined by and evaluated pursuant to the AMA guides or reported significant changes year to year in lung function for FVC, FEV1, or diffusing capacity of the lung for carbon monoxide as defined by the American thoracic society’s interpretative strategies for lung function tests, 26 European Respiratory Journal 948-68, 961-62, table 12 (2005), as updated. 6. The qualified physician signing the detailed narrative medical report has concluded that exposure to silica was a substantial contributing factor to the exposed person’s physical impairment and not more probably the result of other causes. An opinion stating that the medical findings and impairment are consistent with or compatible with exposure to silica, or similar opinion, does not satisfy the requirements of this subsection.2017 Acts, ch 11, §14686B.6Evidence of physical impairment.Evidence relating to physical impairment, including pulmonary function testing and diffusing studies, offered in an action governed by this chapter, must satisfy all of the following requirements:1. The evidence must comply with the quality controls, equipment requirements, methods of calibration, and techniques set forth in the AMA guides and all standards set forth in the official statements of the American thoracic society which are in effect on the date of any examination or pulmonary function testing of the exposed person required by this chapter.2. The evidence must not be obtained by or based on testing or examinations that violate any law, regulation, licensing requirement, or medical code of practice of the state in which the examination, test, or screening was conducted, or of this state.3. The evidence must not be obtained under the condition that the plaintiff or exposed person retains the legal services of the attorney sponsoring the examination, test, or screening.2017 Acts, ch 11, §15686B.7Procedures limitation.1. Evidence relating to the prima facie showings required under this chapter shall not create any presumption that the exposed person has an asbestos-related or silica-related injury or impairment, and shall not be conclusive as to the liability of any defendant.2. No evidence shall be offered at trial, and the jury shall not be informed, of any of the following:a. The grant or denial of a motion to dismiss an asbestos action or silica action under the provisions of this chapter.b. The provisions of this chapter with respect to what constitutes a prima facie showing of asbestos-related impairment or silica-related impairment.3. Until a court enters an order determining that the exposed person has established prima facie evidence of impairment, an asbestos action or silica action shall not be subject to discovery, except discovery related to establishing or challenging the prima facie evidence or by order of the trial court upon motion of one of the parties and for good cause shown. 4.a. A court may consolidate for trial any number and type of asbestos actions or silica actions with the consent of all the parties. In the absence of such consent, the court may consolidate for trial only asbestos actions or silica actions relating to the exposed person and members of that person’s household.b. This subsection does not preclude the consolidation of cases by court order for pretrial or discovery purposes.5. A defendant in an asbestos action or silica action shall not be liable for exposures from a product or component part made or sold by a third party.2017 Acts, ch 11, §16686B.8Statute of limitations two-disease rule.1. With respect to an asbestos action or silica action not barred by limitations as of July 1, 2017, an exposed person’s cause of action shall not accrue, nor shall the running of limitations commence, prior to the earliest of the following:a. The exposed person received a medical diagnosis of an asbestos-related impairment or silica-related impairment. b. The exposed person discovered facts that would have led a reasonable person to obtain a medical diagnosis with respect to the existence of an asbestos-related impairment or silica-related impairment.c. The date of death of the exposed person having an asbestos-related impairment or silica-related impairment.2. This section shall not be construed to revive or extend limitations with respect to any claim for asbestos-related impairment or silica-related impairment that was otherwise time-barred as of July 1, 2017.3. An asbestos action or silica action arising out of a nonmalignant condition shall be a distinct cause of action from an action for an asbestos-related cancer or silica-related cancer. Where otherwise permitted under state law, no damages shall be awarded for fear or increased risk of future disease in an asbestos action or silica action.2017 Acts, ch 11, §17686B.9Application.1. This chapter applies to all asbestos actions and silica actions filed on or after July 1, 2017. 2. This chapter applies to all pending asbestos actions and silica actions in which trial has not commenced as of July 1, 2017, unless the court finds that the application of a provision in this chapter would unconstitutionally affect a vested right. In that case, the provision does not apply and the court shall apply prior law.2017 Acts, ch 11, §18
