After notifying my insurers that I had been diagnosed with primary myelofibrosis I was encouraged by them to make a claim under my critical illness cover. They promptly rejected it after seeking a medical report from my consultant. now, three years later, I'm thinking that I should challenge this. Fatigue has worsened to the extent that working full time has become almost impossible. I was awarded the Personal Independence Payment having submitted a claim but could really do with getting my insurance to pay out as it would allow me to work less hours. Not sure where to start so any help re WHO classifications and info from the Association of British Insurers would be hugely welcome.
