West Coast native Nate Dogg received medical treatment from CareMeridian Rehab Center in Orange County, California in the final stages of his life. But, despite having no issues with the service or claims of mistreatment, Nate’s camp apparently never paid the bill and is now facing a 300K lawsuit.

After Nate Dogg suffered his second stroke in 2008, he moved into CareMeridian, where patients with serious injuries get the rehabilitation they need. According to TMZ, the singer received more than 290,000 dollars in treatment from 2008 to 2010, as per CareMeridian's claims. And, one of Nate's managers, David Michery guaranteed they would get compensated.

Now CareMeridian is suing Nate Dogg's estate, alleging the balance was never paid, even after the death of Nate Dogg in 2011. As a result, the court has entered a default judgement against Nate’s camp, including manager Michery, ordering them to shell out $293,512.52.

Michery told TMZ he stepped up to the plate to pay the bill because none of Nate's famous "rapper friends" offered to help out.

"I was the only person who would come forward because I didn’t want him to die," he explained. "Me and Nate have 20 years history together and I did what everyone should have done and tried to save his life ... not let him get kicked out in the streets and die."

Michery says he intends to pay the hefty bill by releasing several never-before-heard Nate Dogg tracks.

When asked if he regrets taking responsibility for Nate's medical bill, Michery said, "Not at all. I would do it again in a minute. I just wish that the people he looked out for all these years and the people who claim to love him so much would help out."

TMZ spoke with Warren G, who appeared on "Regulate" with Nate, and in his own defense said, "I rode with Nate 'til the end ... I did what I could do for him with other things financially. If I was able to pay for his hospital bill, I would have. I made several calls to numerous people for help. I love Nate ... he's my brother." —Christian Mordi
