Vit B12 inj. in the office

How do you bill for this?

Injection

When the patient is simply being seen for a therapeutic/diagnostic injection
administration, it would be appropriate only to report the drug code and
the administration. 96372 and J3420. Physician must be on-site or can only use 99211.

However...

if the patient is already coming in for an office visit for some other type of problem or even as a follow-up and the doctor sees the patient and documents and office visit, then bill for the visit (99212-99215). If the doctor decides the patient needs to start B-12 or if the patient is due for B-12, then bill 96372 and J3420 for the injection. I usually put modifier 25 on the office visit code and it seems to be paid just fine. Some of our Medicaid carriers don't want the modfiers though. Medicare seems to have a problem with this and I've had to do reconsiderations on those claims, but in the end, they're always paid.

And of course...

be sure the injection is linked to an appropriate ICD code to justify its use and not to the office visit for HTN or DM.
