There is "no valid reason" the province should not reveal the names of physicians and the amounts they bill OHIP, said NDP health critic France Gelinas.
"This is taxpayers' money and the information should be made available to the people of Ontario, with the right disclaimer that we understand this is not the take-home pay," Gelinas said. "It's $11 billion of taxpayers' money that is completely opaque right now. Nobody gets to see it, and that's wrong."
Disclosing doctors' names and billing amounts will show whether or not the Liberals can live up to their claim to be an open and transparent government, said Progressive Conservative critic Bill Walker.
"They brought in the Transparency and Accountability Act, and here's a prime test of it," said Walker. "I'd be prepared to say to the (health) minister: you know the name, why won't you disclose it?"
An ophthalmologist was the highest paid physician in Ontario in 2013, billing over $6 million. At least two other doctors charged over $4 million — and 28 billed over $2 million — but all the public can find out is that radiologists and cardiologists were the next highest billing by speciality after the ophthalmologists.
After contract talks with the Ontario Medical Association broke off last week, Health Minister Eric Hoskins said there were 400 doctors who billed over $1 million last year, but he wouldn't say who they are or where they work.
Ontario budgets $11 billion a year for physician compensation, but most doctors are not covered by the Public Sector Salary Disclosure Act, which lists the names and salaries of people paid over $100,000 a year by provincial taxpayers.
Hoskins said the act "does not permit such disclosure" of doctors' billings, but it's the government that sets the criteria for what is reported on the so-called sunshine list.
Gelinas said the NDP plans to introduce legislation next month to force the government to release the names of doctors who bill over $100,000 a year.
Media outlets have launched an appeal to get more information on doctors' billings after requests through freedom of information were rejected.
The OMA, which represents 28,000 Ontario doctors, said it doesn't actually get the names of doctors with the amounts billed to OHIP, but added doctors with higher billings usually have high overhead costs.
"They often employ a large and skilled staff, use expensive equipment and require a larger footprint than the average clinic," said OMA spokeswoman Danielle Milley.
The average Ontario doctor bills OHIP $360,000 a year, but must pay staff and any office expenses out of that amount, which the group DoctorsOntario estimates at 30 per cent of billings.
DoctorsOntario, which describes itself as a grassroots organization dedicated to protecting physicians' rights, freedom and independence, is planning a job fair in the spring "to help doctors, especially the nearly 20 per cent of new specialists who are unemployed, find work in friendlier jurisdictions."
Hoskins said the Liberals have hiked doctors' salaries by more than 60 per cent since they came to power in 2003, which helped stop physicians from leaving Ontario to work in other provinces or the United States.
"We corrected the situation a decade or more ago when there was a brain drain of physicians leaving the province," said Hoskins. "We now have the opposite, where the income potential of physicians in this province is such that it is attracting physicians."
If any of the highest billing doctors made any inappropriate claims, the Ministry of Health would have detected them, said the OMA.
"The ministry has clear processes in place to ensure billings are appropriate, which includes regular auditing of doctors' billings, and that is especially true of those who bill higher than their specialty's average," Milley said. "If the ministry paid them, clearly they believed they were providing value for that money."
A study by Roger Martin at the Institute for Competitiveness and Prosperity, an independent research group supported by the Ministry of Economic Development, said doctors' compensation is adding to rising health care costs. At $51 billion this year, Ontario's health-care budget eats up 42 per cent of government program spending.
"Engage physicians to be leaders for change and renew the payment model," wrote Martin, the former dean of the Rotman School of Management at the University of Toronto. "Use peer performance data to stimulate healthy competition among providers."
The NDP said many medical specialties have had huge technological advances that allow procedures that used to take hours to be done in a fraction of that time, including eye surgeries, but doctors are paid the same rates as before.
"Those in the million-dollar club are basically surgical specialties that have evolved so much, but the payments remained the same," said Gelinas. "Things have changed for the better, but the savings have certainly not been passed on."
Ontario's Information and Privacy Commissioner declined to comment because of the ongoing appeal of the FOI ruling, but has spoken in the past about a growing trend towards greater transparency when it comes to government expenditures.
British Columbia and Manitoba already release information on physician billings to the public.
