In my limited experience, when you already have an IEP for something else, i.e. speech, the school may be more willing to incorporate newly identified needs into an existing IEP. For example, I know several people who got OT services through school when there was an existing IEP for some other issue.

What do you plan to ask for? If you want some type of supplemental instruction and/or curriculum modification, i.e. Orton-Gillingham reading instruction or a reduction in amount or scope of work, then you are looking for an IEP. A 504 plan will only allow accommodations that allow the student educational access. Often these include extra time, ability to keyboard (but not keyboarding instruction), using t-stands or fidget balls, etc. Typically, students do not get supplemental instruction or curriculum modifications under 504s.
