You can bill 99211 as long as the complete documentation is there and the pt is an established pt returning for a physician ordered service. I was in a class where the following criteria were given for the nursing/MA documentation that would qualify for billing 99211: 1) the order from the physician 2) the reason for the service (dx) 3) nursing assessment as inidcated 4) nursing action as indicated 5) patient instructions 6) follow-up 7) nurse's legible signature (not initials) and credentials. Further, the supervising physician must be in the office at the time of the encounter.
Remember, the description of 99211 includes "evaluation and management" so this must be shown in the documentation. The evaluation portion is substantiated when the record includes documentation of a clinically relevant and necessary exchange of information between provider and patient. The management portion is substantiated when the record demonstrates an influence on patient care (eg, medical decision making, patient education, etc.).
You would want to check payor specifics as well.
I want to add that I'm not sure I agree with billing 99211 when a patient comes back in for a blood draw or other service required by the physician as it seems an excessive expense for the patient. However, I do also understand that if medically necessary and the documentations supports it, it can be billed.
