I would expect your wife to have to fill in an ESA50, but based on your description of her treatment, she should be exempt from the WCA medical. You can read about the process and exmptions for ESA in the Understanding ESA document in the Members area.
Your wife's claim should not cause a re-assessment of your own, but you may be transferred to ESA as part of the IB Transfer, on or after July.
Hope this helps
