What is the formula for calculating the prescriber's DEA #?
Step 1 The first letter should be an A, B or M. It doesn't matter which one
Step 2 The Second letter must be the first initial of the prescribed /doctor's last name
Step 3 Then look at the numbers...add the 1st, 3rd, and 5th numbers together. Hold total
Step 4 Then add the 2nd, 4th, and 6th numbers together....take the sum and multiply by 2
Step 5 Lastly add the two sums together. The last digit from your final sum must match the last digit on the doctors/prescribers DEA number.
