Your point is simply wrong. Especially in underserved rural areas you'll often see primary care doctors delivering cardiology and nephrology treatments even though they lack board certification in those specialties. There are no certified specialists available so they make do.

You guys need to expand your horizons a bit.

“Practicing” and providing maintenance care of a condition are two completely different concepts, and the point you replied to stands.

[nradov]

Nah, the point was just wrong. In many cases these primary care doctors are doing more than just maintaining a treatment plan prescribed by a specialist. Apparently you don't understand how the practice of medicine is legally defined in US states.

[foco_tubi]

I might say the same about your stance, especially considering all you've offered up as evidence are hypothetical situations.

Primary care doctors are performing heart surgery?

There's a lot more to cardiology than performing heart surgery. Many cardiologists don't perform surgery either.
