So I should get a new tax code? When will this happen?

My tax code has changed to recover unpaid tax from high income child benefit from a previous year & to cover high income child benefit for the current tax year. The change to the HICB threshold means that I will only have to repay a small percentage of this year's HIBC, so will my tax code be adjusted accordingly or will I have to reclaim any overpayment later?
