What exactly does "column 1" mean in the column 1/column 2 correct coding edits table?

If the two codes of a National Correct Coding Initiative (NCCI) procedure to procedure (PTP) edit pair are reported for the same beneficiary by the same provider for the same date of service, the column 1 code is generally the only code eligible for payment. However, if the NCCI PTP edit allows use of NCCI-associated modifiers (i.e., modifier indicator of "1"), use of an appropriate NCCI-associated modifier allows both codes of the edit pair to be eligible for payment.
