With back pay.
How i applied
Called Social Security set up phone interview a month in advance. They had wrong so missed that call. Called again set a time a month later. Call came this time. Very pleasant lady took my info and ask questions for about 30 minutes. Told me it would take 3 to 6 months to get answer. Got notice to go see 2 doctors but they canceled them when they received all my records. Have not received any paper work just reviewed my information on line. The back pay is already in the bank. I was already receiving Social Security benefits so they direct deposit it in my account. Took 3 months 4 days from first call i made. They outsource the review process here in Texas. I think that is why it was so quick. I received 9 months of back pay. It was just the amount over what i was receiving. I retired at 62 and the amount i receive is the same as i would get if i waited until i was at full retirement at 66 and i will get it until i die or until we (almost said they) run out of money.
