The Australian Defence Force (ADF) denies claims armed force personnel could have access to fewer medical specialists under a new health agreement.
The ADF says reforms undertaken by the forces will efficiently deliver healthcare to all entitled personnel.
The Australian Medical Association (AMA) released a survey on Tuesday where less than nine per cent of 600 specialists who previously provided care to ADF personnel said they had agreed to the new preferred provider network.
The row over specialist health services relates to the $1.3 billion deal signed with Medibank Health Solutions (MHS) in June for the provision of health care to defence personnel across Australia.
"Under this model ADF personnel have access to timely, high quality health services regardless of location," the ADF said in a statement on Wednesday.
"Despite the claims of the AMA, this major reform is well and truly being rolled out."
The ADF said the MHS had signed 3503 medical specialists, 6884 allied health specialists and 202 hospitals.
""As a ratio, the specialists available to treat 80,000 defence personnel is over three times the number available to treat the broader Australian population," it said.
AMA president Steve Hambleton said the new result of the new system was ADF personnel could have fewer choices to specialist care.
But the ADF said no personnel had been denied access to any medical treatment or recovery.
