Pinotti broke two ribs and his left collarbone during the individual time trial in February.
The five-time Italian national time trial champion has been training for six weeks to rebuild his fitness.
"I guess I'm halfway in the recovery process," he said.
"Having been sidelined four-and-a-half weeks, I need about 12-13 weeks to get back to my former level."
Pinotti's BMC team-mate Cadel Evans said the race is an important part of his preparation for the Giro d'Italia.
"I look forward to racing on long and hard climbs in a good field," the Tour de France winner in 2011 said.
"I just want to be able to ride well with the team and use it to get ready for the Giro d'Italia."
Evans will face last year’s Tour de France winner, Bradley Wiggins, as well as Vincenzo Nibali, Michele Scarponi, Stefano Garzelli, Domenico Pozzovivo and Ivan Basso in the four-day race which will serve as an appetiser for the fight for the pink jersey.
Six WorldTour Teams (Lampre-Merida, Cannondale Pro Cycling, Astana, Ag2r La Mondiale, BMC Racing and Team Sky) will be at the start in Lienz, sharing the stage with some of the top Italian and International Pro-Continental outfits: Androni Giocattoli - Venezuela, Bardiani-CSF, Vini Fantini-Selle Italia and Team Colombia plus Europcar, MTK-Qhubeka and Champion System.
