This isn’t HIPAA. Talking about patients, procedures, insurance issues, etc. without identifying information doesn’t violate HIPAA. The original post from the doctor didn’t have patient information.

Most likely this is UHC telling him to remove it or they’d blacklist him and any medical group he works for/with. An individual doctor is easy to threaten. And just adds more proof to what we already know about the “Walmart of healthcare” that is UHC.
