The world number one, who is due to begin his Australian Open title defence against Nicolas Jarry on Monday, twice tested positive for the banned substance clostebol during last season's Indian Wells Masters in March.
Sinner was subsequently cleared of any wrongdoing by an independent tribunal, successfully arguing he had been inadvertently contaminated with the substance - a steroid used to build muscle mass - by his physiotherapist.
The International Tennis Integrity Agency (ITIA) accepted there was "no fault or negligence" on his behalf.
However, the World Anti-Doping Agency (WADA) has appealed against that verdict, arguing the ruling was "not correct under the applicable rules".
WADA is requesting a ban of "between one and two years" for the 23-year-old, whose case will be heard from April 16-17.
In a short statement, CAS said: "No parties requested a public hearing, and it will be conducted behind closed doors."
