The Ornish Reversal Program was established by Dr Dean Ornish. This program is centered around a Whole Food Plant-Based diet for combating heart disease.
Is Ornish Reversal Program covered by health insurance? In 2010, Medicare (US Government health insurance system) approved the Ornish Reversal Program for rehabilitation of heart patients. Today, the program is covered by several other health insurance providers — see list of providers.
What's the quality of scientific evidence behind Ornish Reversal Program? A 37-page summary called Ornish Literature Review has a step by step buildup of a 'story' over 30+ years. It explains, 'in 2019, why do we feel reasonably confident that the Ornish Reversal Program reverses heart disease'? Note that we're talking about 'reversal', not merely 'management'. An animated timeline of his major publications from 1978, 1983, 1990, 1998, 2005, 2008, 2010, 2013 is presented at Undo It webpage (scroll down to see "The Proof" timeline).
The same talk is available at TED.com (17 mins, 2004). Dean Ornish's talk is not focused on heart disease alone. He talks about healing through diet in general.

In 1990, Dr Dean Ornish surprised the medical community by demonstrating through a randomized controlled trial that heart disease could be reversed in a majority of patients! His interventions were fourfold: (a) a low-fat vegetarian diet, (b) no alcohol, (c) walk half an hour every day, and (d) pursue stress reduction activities like yoga and meditation.
Before Ornish's work, nobody in the medical community believed that heart disease could be reversed. Soon after publication of his initial research in 1990, Dean Ornish convinced an insurance company to try his program on patients scheduled for bypass surgeries. The results were fantastic: patients didn't need surgery. As a result, the insurance company saved about $30K per patient.
20 years later, Medicare adopted the Ornish Reversal Program. Many other health insurance companies followed.
Note: Since 1990, our understanding of relationship between lifestyle and heart disease has improved. In fact, a Whole Food Plant-Based community has come into being. For the latest guideline and optimal results, I encourage my friends to adopt Dr Esselstyn's food system, which is stricter than Ornish's original studies. Also, there is no emphasis on meditation or stress management; there is a lot more emphasis on food.
Who is Dean Ornish? Some of my Indian friends refuse to believe that heart disease can be cured. They wonder, "Who is Dean Ornish? How come I have never heard of him?" To help them, I point them to the Wikipedia Page for Dean Ornish. Dean Ornish's original research paper was published in The Lancet ("Can lifestyle changes reverse coronary heart disease?", 1990) which is a top-notch medical journal. Dean Ornish is also the family doctor for former US President Bill Clinton and his wife Hillary Clinton. He influenced Bill Clinton to change his diet after he had a heart attack in office.
In late 1970s, how did Dean Ornish get the idea that a very low-fat diet without meat, without alcohol, with some mild exercise (walking for half an hour), and some relaxation technique (yoga and meditation) could reverse heart disease? These interventions were the basis of his 1990 study that demonstrated that heart disease could be 'reversed' (not just 'managed' but 'reversed'). The story is captured in a New York Times article from 1998: Scientist at Work: Dean Ornish.
