Performing EAPG calculations manually requires that you look up the assigned APG group for the billed code. You must then look up the APG “base weight” for that APG group and multiply that number by the “weight multiplier.” Next, multiply the sum of that number by the established “base rate” for that region, then add the capital add-on fee.

In summary:

APG Group –> Base Weight  X  Weight Multiplier  X  Base Rate + Capital Add-on = Final APG Payment

For further explanation, see page 9-10 of the APG Provider Manual. Additionally, numerous other factors must be considered in determining proper reimbursement amounts. See APG Provider Manual.
