Dr. Bailey absolutely committed insurance fraud

I was rewatching Grey's and noticed that in S5: E2 Miranda made Karev set back the clock in the OR so that the official insurance documents for the patient had "11:58pm" written instead of "2:28am" which was the actual time. So, why did Shonda decide to dedicate half of a later season to Meredith and her whole insurance fraud thing, but this just went right on through.?!
