A coil tubing hanger includes a hanger body having a hanger base with a lower end for connection to a well tree, an upper end for connection of a hanger cap and an internal cylindrical cavity for receiving an annular, externally actuated, pack-off element for selectively providing a high-pressure fluid seal against the coil~ tubing. The hanger cap seals the cylindrical cavity and provides a slip bowl. Slips received in the slip bowl suspend the coil tubing. An injection nipple mounted to the slip bowl includes an injection nipple port through which the coil tubing extends, and a surface pack-off provides a high pressure fluid seal around the coil tubing above the slips, so that the pack-off element may be released from the coil tubing after the coil tubing is landed and the surface pack-off is secured.
