I just got my BBE in the mail and I was service connected for all BUT I had no idea why it was 0% service connected......(thought it would be 30%) To clarify for anyone who may be like me and not understand the VA's policy on Corticosteroids or "systemic therapy".... Here it is hot off the press from the DRO from my NOD verbatim.... Note: Corticosteroids are anti-inflammatory drugs that are synthetic derivatives of the natural steroid, cortisol, which is produced by the adrenal glands. They are called "systemic" steroids if taken by mouth or given by injection as opposed to topical corticosteroids, which are applied directly to the skin. Corticosteroids that are applied topically are not considered systemic for VA purposes. So unfortunately for me I've been on the topical Corticosteroids for the last year and that doesn't cut it for the ratings....please don't tell my liver this..lol Hope this can help some fellow vets and save a little frustration.
