I'm afraid ESA claims can be reassessed at any time once 3 months have elapsed since the last Decision was made, so I am afraid there is no way for you to avoid this.
This is a full reassessment of your claim so you need to complete the ESA50 in detail and provide evidence in support as you can, even if you have previously submitted it.
Please make use of our ESA Claim guides which detail the criteria against which you are being assessed against and the latest DWP guidance.
