Anyone else recieve SSI Disability for their child and turn in MWR every month? Have you ever made to much?

My son receives SSI Disability benefits because he has a form of Austim and ADHD. Normally we turn in our monthly paystubs for them to determine how much he gets in the following months. This month however my husband gets a bonus that will put us over the income limit for a check from SSI. My fear is they will cut him off because we made to much in Dec and we will have to go through a long process to reinstate him. It isn't the lack of SSI check that scares me, its his medical coverage. I spoke with a rep from SSI this morning and she said it would cut off his check and medical but when we turned in January paystubs it would start again. I am worried about the length of the process. Anyone else have experience with this?
