Most likely, the answer is "No."  Section 287.140 .8 sets forth the extremely limited circumstances under which a settled claim can be reactivated.  A claim can be reactivated only "after the claimant can show good cause for the reactivation of the claim" AND "the claim shall be made only for the payment of medical procedures involving life-threatening surgical procedures or if the claimant requires the use of a new, or the modification, alteration or exchange of an existing, prosthetic device."  Under this law, "life threatening" means "a situation or condition which, if not treated immediately, will likely result in the death of the injured worker."
