However, on Wednesday, Nashville's News 2 Investigates discovered the sensitive information was still easy to access online.
The document in question is a 2000 nonprofit tax return consisting of hundreds of pages that include names, addresses and social security numbers, all of which have appeared online.
One of the names Nashville's News 2 Investigates uncovered is private information belonging to Lebanon City Councilwoman Kathy Warmath.
Warmath previously worked for Tenet Healthcare in Wilson County for several years and donated money to charity, which the company matched.
"Identity theft is huge. I would say that anyone on that list is vulnerable," Warmath said.
Steven Campanini, Tenet's Vice President of Corporate Communication, refused to speak with Nashville's News 2 Investigates regarding the incident, but did re-release a two-week old statement blaming the data breach on others.
According to his statement, the information was released by FoundationSearch.com, an online database focusing on funding for non-profits.
Campanini indicated the government released the information in response to a Freedom of Information Act request.
"We worked with the Web site to have this information immediately removed. The individuals' information should have been deleted before it was released by the government. We are working with the appropriate government agencies to ensure that this information is not released again in the future," Campanini explained.
Warmath, however, said she believes the healthcare giant needs to correct the problem immediately.
"Tenet you need to get your act together because in the end it's going to cost you a lot more than it cost me," she said.
Warmath added she has yet to hear from the Tenet Corporation nor has anyone offered her or other victims financial protection coverage.
Warmath said she and her former Tenet colleagues are considering legal action to get the company's attention.
