I’m trying to assist a family member’s family medical practice. I’ve signed up for the CPB course thru AAPC that starts in November. In the meantime, I was wondering if someone could assist me with the below.

67 yo female presents to the office for labs. Wants the flu vaccine.

Billing for . . .
99214 office visit
90472 immunization admin
96372 therapeutic prophylactic injection
1033F tobacco non-smoker (I know this isn’t covered)
4035F Influenza immunization recommended (probably not covered)
3008F BMI (not covered)
I think the Fs are for reporting purposes from what I’ve found.

When I submit the above, I get the following . . .

Code 99214 is a component of code 90472 but a modifier is allowed on 99214
Code 99214 is a component of code 96372 but a modified is allowed on 99214
The procedure code 90472 is defined as an add-on code
The procedure code 90472 is invalid or requires a parent that is not on the claim

I’m unsure when to add modifiers like 25, 59, QW, etc. When I add 25 modifier to 99214 I get
The procedure code 90472 is defined as an add-on code.
The procedure code 90472 is invalid or requires a parent that is not on the claim.

Any assistance anyone could give would be greatly appreciated.
TIA
