Wiki commercial modifiers for denied auths

[krisinda2001@yahoo.com]

I am wondering if there are any modifiers available when submitting a claim for payment after the authorization was denied but a waiver was obtained? Are the GA, GX, GY, GZ modifiers specific to Medicare only or can they be used on claims to a commercial payer?
Thanks for your help!

I believe they're Medicare-specific. If anyone else differs, please chime in with a good resource. I'd like to look into myself.
