Why do the paper thin walls between exam rooms at my doctor's office that allow me to hear entire conversations while I am waiting (and waiting) not violate HIPAA?
Clinics that deal with the most sensitive medical needs tend to be more careful. HIV testing, reproductive health, psychiatry, hospice.
Addiction treatment falls under 42 CFR II, colloquially known as “part 2”[0]
Part 2 data is significantly more encumbered than other medical data. If I want to get it I need to be explicitly allowed as a named entity by the patient to receive it. If the data is shared with me under a “general designation”whoever gave it to me has to record that and tell the patient on request. And I have no TPO carve outs, I have to get explicit consent to pass it along.
It is, often times, treated as radioactive data - my company deals in medical data but explicitly says in our contracts that we refuse any receipt of it.
