Yes, absolutely. Not only is it likely that you will receive regular requests for updated information relating to your disabling condition (and its progression) from your insurer, but insurers will expect you to keep them apprised of any material changes to your medical condition(s). You must provide updated information as you bear the burden of the proof of loss as the insured under most disability insurance policies.

It’s critical that you do not forgo such notification, or you could not only lose your benefits, but you could also be held liable for damages.
