It was feared the New Zealand-born flanker might never walk again after suffering a serious neck injury in a Premiership game on January 4th.
Fatialofa spent almost three weeks in intensive care in London.
He was then transferred to a rehab unit at the private Royal Buckinghamshire Hospital.
He should have been moved to the NHS Stoke Mandeville hospital next door, but there were no beds available.
And he has now received a bill, reported to be $200,000 for his time at the Royal Buckinghamshire Hospital.
