In any case where an injured employee makes application in writing for a further adjustment of his or her claim under the provisions of section sixteen, article four of this chapter and the application discloses cause for a further adjustment, the commission shall, after due notice to the employer, make the modifications, or changes with respect to former findings or orders in the claim that are justified. Any party dissatisfied with any modification or change made by the commission, the successor to the commission, other private insurance carriers and self-insured employers, whichever is applicable, is, upon proper and timely objection, entitled to a hearing, as provided in section nine of this article.
