Some electronic claims for behavioral treatment services have been submitted using an incorrect qualifier to identify the rendering provider. When submitting electronic claims for behavioral treatment services using the 837 Health Care Claim: Professional (837P) transaction, providers are required to use the G2 qualifier to identify rendering providers that do not have a National Provider Identifier. At the header level, providers should enter "G2" in the REF segment of the 2310B loop when the rendering provider is the same for all or most of the details. At the detail level, providers should enter "G2" in the REF segment of the 2420A loop for each detail where there is a different rendering provider from the rendering provider indicated at the header level.

Providers who use an outside billing service or clearinghouse should contact them to ensure they are billing properly.
