I have been on LTD for 2.5 years (so am accepted past COD date) and on a slow extended return to work plan. Is there a standard expectation for supplying medical information to the LTD company when I seek additional help to further resolve my condition, or is medical information only exchanged on request from the LTD company? Also, does the LTD company have to pre-approve any new or changes to existing medical treatment? Or are the answers specific to each policy. I'd like to know what is reasonable and expected under the law.
