I am traveling to the UK for a couple of months and want to buy an insurance (seems like I can only opt for nomad/international insurance purchased online from any point in the world as conventional policies in my country are up to 31 days). However, I have a diabetes and I am very worried if the company will refuse the claims for made up reasons not even directly related to the condition (like: "You spilled hot water because people with diabetes may theoretically have neuropathia, oh well, you did a regular nerve checkup and didn't find anything? But it means that you have received diagnostics on that condition! Refused!").
I know I am exxaggerating, but can anyone advice on the insurance company/plan that will fit my needs? If possible, not very expensive (below 150 USD per 2 months). I am not a U.S. resident. I do not need regular diabetes treatment covered. The acute onset of the diabetes itself is actually very unlikely, so my only concern is that the insurers will attribute injuries etc to diabetes.
I found the Patriot Platinum plan by IMG that explicitly covers "acute onsets". However, IMG has very bad reviews here (as well as Atlas and SafetyWing... all the insurers have bad reviews).
