Training & certification expected
No state-mandated injector training beyond licensure.
The license that lets you inject
MD, DO, NP, PA, RN under physician supervision
If you’re an RN
Yes, under physician delegation; specific scope defined by board rules
Why the order still matters
Required; in-person exam by physician before treatment Training gets you the skill; a valid order or good-faith exam is what keeps the treatment lawful.
What to verify in Tennessee
Ensure a Tennessee-licensed physician medical director is in place and that all RN/NP/PA injectors have signed collaborative agreements or delegation protocols.
