Hey if your just coding a physical with a PaP smear.
Just bill
99385-99387 series
or
99395-99397 series
depending if there new or est.
And if your practice is just collecting and sending the pap smear out use
Q0091 with V76.2.
Example
99385- V72.31
Q0091- V76.2
Regarding the G0123 or 88142.
The G0123 looks like this only applies if your collecting the pap smear and reading the sample inhouse.
And 88142 is what the pathologist use when you send out the pap smear to them. So becareful in some of the advice you receive regarding your question.
Also the first scenario you posted is correct. But most PPO will not reimburse for the 99000 for the collection of a pap smear. Little trick to the trade. Thats why many coders picked up the Q0091.
