My husband received another VCAA informing him they were working on a claim for TDIU. He never filed a TDIU. Upon further investigation through our VSO and Jim Strickland, we found out: When the VA receives a claim for a disabling disease that is now presumtive, if there is sufficient evidence included that the Vet is unable to work due to this disease, a TDIU will be generated by the VA and adjudicated together. We did not fill out the TDIU request because my husband has a AICD implant and should be rated 100%, therefore making the TDIU moot. Checked the box, no other evidence, please decide my claim in 30 days. If the rating comes back less than 100&, will be working on a NOD, not a TDIU. This change will help Vets with an expectation of a rating 60-90%....wanted to pass it on.
