I agree that since you are the "host" you sort of got paid for doing this. However, you might up your monthly fee just a bit, and cite the new "PCI requirements" for having increased your tasks.
I think that is justified - the PCI requirements demand a higher level of server security than a basic website. Since the scanning companies are getting more stringent, then I think a monthly increase is justified.
I helped a client recently with getting PCI compliant, and I charged my time, because I'm not the hosting provider.
