Generating a Bitcoin Address QR code with current USD price embedded?
You can't include the USD amount, but you certainly can include the btc amount in the QR code. The QR code essentially embeds a text like this:

bitcoin:1ArmoryXcfq7TnCSuZa9fQjRYwJ4bkRKfv?amount=0.005


Note the amount here is the amount in BTC. You can generate a QR code for that text using gobitcoin.io. If you just want to insert an image, you can use googleapi.com to generate it. For example, a url like this:

https://chart.googleapis.com/chart?chs=250x250&amp;cht=qr&amp;chl=bitcoin:1ArmoryXcfq7TnCSuZa9fQjRYwJ4bkRKfv?&amp;amount=0.005

will generate a QR code like this:
