Can we bill CPT 99211 when a patient comes in only for a protime
No you cannot. You use the blood collection code. You have no significant medical service other than the blood collection to render therefore there is no justification for the 99211.
I have a provider that bills a 99211 with an INR lab when he has to adjust the coumadin regime. I have not read anywhere where he cannot do this.
