I'm not sure if this is really "advice" as it is more of an explanation. I know a little about
this stuff b/c my husband used to work in LTD claims. Each policy has different coverage set by the contract with the employer. Some have maximum benefit times regardless of whether you are still disabled. Typically any "self-reported" disability has the shortest benefit time. Self-reported does not mean you are making it up. It means there is no concrete proof a doctor could give the company. Good
examples are pain and depression. Depression is diagnosed based on symptoms reported to the doctor, not based on a cat scan that sees a tumor. So your CD would probably be covered under the longer provision because it is verifiable by tests. However, CD alone doesn't make one disabled. It is the symptoms, and those are often self-reported. If the part of your CD making you disabled is bathroom trips and pain those can't be "proven" by the doctor. If the part making you disabled was fistula, abcesss, etc. then you would probably fall under the other longer coverage provision.
So assuming your symptoms are mostly self-reported they evaluate you under step two (and since it has been 2 years) to see if with an accomodation you could work any job. They found that you could work a seated job. That is not enough for them to find. There has to be jobs available, in your area, for which you are qualified that provide that accommodation. I believe even if they close your claim they are supposed to transition you. Give you a career coach, help you find the kind of work that you can do, start you with a reduced schedule, etc. I would call the disability company and ask about
getting those kinds of benefits if you lose your appeal for full coverage.
I am guessing that if you read your contract there will be a strict time limit on self-reported disabilities. Even verifiable disabilites (ie: cancer) have a time limit on how long one can receive benefits under some plans.
They will also take into account if you could work with accommodations such as frequent bathroom breaks, reduced work schedule, adjusted work station so you can alternate sitting and standing, etc. SSDI may still find you disabled because they don't have a time limit on their coverage. It is a government benefit.
Edited to add: also look at your contract to see what qualifies as symptoms of the disability. Under 99% of plans not being able to drive has no bearing on if you are disabled. I don't know how they expect you to get to work if you live in a rural are but those are just the arbitrary rules. I guess they want you to carpool or something. Also, being on a medication that effects your ability to concentrate does not qualify under a lot of plans. You didn't elaborate on why you can't go back to work so I can't give you my opinion if they are reasons the company will accept.
