A FORMER Tweed Hospital doctor has accused the NNSW Local Health District of attempted fraud, Medicare double-dipping, bullying and unfair dismissal, in a matter before the Fair Work Commission.
Dr Leong-Fook Ng worked for the hospital as a specialist oncologist between May and November 2006.
The Cambridge University-trained doctor was stood down over "communication skills" that same year - allegations that were later quashed on appeal.
He alleges the claims were a reaction to him raising a matter about the hospital using his Medicare number to double-dip - a practice in which services already funded through the Federal Government are claimed a second time through Medicare.
The NNSW Local Health District has denied all of Dr Ng's claims and applied for the matter to be dismissed.
In its submission, the health district said Dr Ng's concerns were "without substance in every instance".
It pointed to Dr Ng's referral of reports of alleged fraudulent and unsafe practices to the Independent Commission Against Corruption, NSW Ombudsman and Health Care Complaints Commission as evidence his claims were unsubstantiated.
"None of these proceeded with further action, after examining the material provided to them by Dr Ng," the submission states.
