Billing 95165 for Allergy Serum along with Injection

Pearland, TX
Best answers
For 2016, I understood 1 injection would be 95115 @ 1 unit and for 2+ injections it would be 95117. However, when billing the serum the confusing part comes into play for me and the physician.

The CPT code book states that for 95165 Professional services for the supervision of preparation and provision of antigens for allergen immunotherapy; single or multiple antigens (specify number of doses).

How do I specify the number of doses? I understood 1 dose = 1 unit. Is this correct?

Doesn't the number of antigens per vial matter?

Can someone provide an example of contents in 2 separate vials and how it is billed with CPT 95165?

Thank you,
