Simon Buckden, 42, of Landseer Way, Bramley, Leeds, is accused of making false representations about his medical conditions.
He pleaded not guilty to seven counts of fraud at Leeds Crown Court and is to go on trial in February.
Mr Buckden spoke only to enter his not-guilty pleas.
He is accused of obtaining a free therapy session and places on courses after saying he had cancer and PTSD.
He is also charged with obtaining money as a result of saying he was a cancer patient.
A further charge says he lied about PTSD and cancer, resulting in a film being made about him.
The charges relate to a period between 1 April and 31 July 2012.
Judge Guy Kearl QC said a review of the case would be held on 25 September.
A former soldier and fundraiser charged with fraud has denied lying about having cancer and post-traumatic stress disorder (PTSD).
