I want to add an external PA to the NRF51422. My understanding of 15.247 is that you can transmit up to 30dBm if you use spread spectrum. Does the NRF51422 use DSSS for Bluetooth or ANT?

In addition to Cocoa's answer: Note that the bluetooth specification for low energy says that the transmitting power of a device must be within -20 dBm to +10 dBm. (Core_v4.0.pdf, Vol6/Part A/3 Transmitter characteristics. page 2181)
