Check out this link.
I have reached out to my billing/coding instructor from a few years back (I graduated with my AOS in billing and coding in 2014) for documentation to help further explain the code 99211 and when you can and can not use it when billing for vaccines. Also, I have been personally told from Mo HealthNet’s Dana L. Bernier, a Provider Education Representative,that we can not bill 99211 with vaccines alone.
(Also, there is no such thing as the “two touch rule”.)
Hope this helps everyone!
