I cannot create a summary of the requested article because the full text of the article titled "Opinion: Congress must pass legislation to ensure Medicare covers breakthrough medical technologies" is not found in the search results provided. The available results only contain basic information about Medicare as the US health insurance program, but not the content of the specific article you requested to be summarized. I would need the full text of this article to create an accurate and factual summary as per your requirements. If you have an article available, please share its content and I will create a brief summary in Slovak for you.
