No, you should not change the code in Box 7 of the 1099-R. The Code should be reported as shown on the 1099-R. If you feel the Code on your 1099-R Box 7 is incorrect, you need to contact the payee and ask them the question of whether it is the correct Code. If it is found to be incorrect, they should issue you a corrected 1099-R with the correct Code.
