Hanneken, Kevin v. Consolidated Nuclear Services, LLC
Mr. Kevin Hanneken, a 61-year-old machinist, sought workers' compensation for binaural hearing loss, claiming his employer, Consolidated Nuclear Services, LLC (CNS), was liable for an aggregate 14% permanent medical impairment, which included a pre-existing 5% impairment. The central legal issue was CNS's liability for this pre-existing condition, given that Mr. Hanneken had an ascertainable rating at the start of his employment. The court ruled that the 'last injurious injury' rule does not apply under the Workers' Compensation Reform Act of 2013 when a pre-existing impairment is readily ascertainable. Consequently, the court found CNS not liable for Mr. Hanneken's pre-existing 5% hearing loss. Mr. Hanneken was awarded nine percent permanent partial disability for the increase in hearing loss during his employment with CNS, amounting to $34,749.00 in benefits, along with medical treatment for his bilateral hearing loss.
