Health Minister Mary-Anne Thomas revealed the final carve-up on Friday after the Victorian government announced its hospital networks plan in August.
The 12 geography-based local health service networks will begin operating from July 1 and are expected to share support services and back-office functions to reduce duplication.
A state government-commissioned expert review highlighted the need for "fundamental change" to the public health system and recommended some regional health services be forcibly amalgamated.
But Ms Thomas reiterated the groupings, determined following consultation, would not involving mergers.
"Every health service will retain its own identity, its own board of management and so on," she told reporters.
"But of course we want our health services to work better together and where it makes sense to look at back-office operations and combine those, then we would welcome that."
The networks were first announced alongside a $1.5 billion, one-year funding lifeline for hospitals following backlash at being told to tighten their belts.
Ms Thomas declined to say how much money the networks would save the cash-strapped state budget, declaring they were designed to deliver improved patient care.
Opposition health spokeswoman Georgie Crozier, who has previously dubbed the plan "amalgamations by stealth", called for Labor to give hospitals clarity on their funding beyond this financial year.
"While Labor focuses on paperwork, patients are left waiting," she said.
