The matter relates to multiple breaches of Rule E8(b) for misconduct in relation to betting.
Gosling has requested a personal hearing, on a date yet to be arranged.
Rule E8(b) specifies players must not bet either directly or indirectly or instruct, permit, cause or enable any person to bet on any result, progress or conduct of a match or competition in which they participate or have participated in during a season or in which they have any influence.
The 24-year-old is back at St James' Park following a spell on loan at Sky Bet Championship side Blackpool earlier in the season.
Devon-born Gosling began his career at Plymouth before attracting the attention of Everton, who signed him for £2m in January 2008.
He played 37 games for the Merseysiders to secure a permanent place in David Moyes' side before joining Newcastle on a free transfer in July 2010.
