Clarification for G-codes and the associated charge

Several ambulatory surgery center (ASC) leaders have reported questions concerning how to report G-codes with no associated charges, according to the ASC Association (ASCA) web site (

Per the QualityNet web site (, quality data G-codes must be entered on the CMS-1500 claim form and have an associated charge to be accepted into the Centers for Medicare and Medicaid Services (CMS) warehouse. These codes will populate fields 24 D and 24 F on the CMS-1500 claim form, the ASCA says. Consider these other tips:

• The submitted charge field cannot be blank.

• The line-item charge should be the numeral “0” (zero). Please note that dollar signs ($) or decimal points are not accepted.

• If a system does not allow a zero line-item charge, a nominal amount can be substituted; the beneficiary is not liable for this nominal amount.

• Entire claims with a zero charge will be rejected. The total charge for the claim cannot be zero.

• When a zero charge or a nominal amount is submitted to the carrier or contractor, payment for the amount included in the ASC QDC line is denied and tracked.
