Industry super fund Health Industry Plan (HIP) has extended its insurance cover for members, adding new medical advice services to its existing policies.

HIP said the extended cover was achieved in partnership with its provider, MLC Group Insurance.

"This value-add further demonstrates HIP's dedication to the provision of relevant member services and benefits and could even prove to be life-changing for some," HIP chief executive Ross Bernays said.

"HIP members will automatically be able to access this service immediately at no additional cost."

Members of the $580-million fund will have access to medical specialists around the world through Best Doctors, an organisation founded by doctors from the Harvard Medical School in 1989, which helps people in over 30 countries.

Best Doctors operates through a global database of consultants, with experts chosen by other specialists as the best in their field, and the service allows members to obtain independent and confidential medical advice.

The consultant performs an in-depth assessment of the member's case by reviewing all original medical documentation to provide a full report to ensure accurate clinical diagnosis, providing members the confidence, clarity and certainty to move forward with the most appropriate treatment.

"The Best Doctors service provides peace of mind to members beyond the financial security of insurance cover and we are proud to introduce this innovation to HIP's members," MLC group insurance general manager Megan Beer said.
