All ESA claims are re-assessed on a regular basis so this is perfectly normal.
It's also normal for Maximus to contact the claimants GP, they don't do this for a lot of claims but they do it where they need additional information, it may mean that you do not have to have a face to face assessment.
If you have a look at the ESA guides they explain the process in more detail.
