What 95165 covers
This service covers an allergist's selection of allergens and concentrations and supervision of custom extract preparation in multidose vials. Allergy and immunology practices typically prepare extracts after testing and clinical history identify relevant sensitivities to pollens, molds, dust mites, or animal dander. The preparing practice may administer the shots or send the extract to another office, such as a primary care clinic. Preparation does not include administering an injection.
Report units based on doses prepared, not shots given. For Medicare, one dose is a 1 mL aliquot from a multidose vial, regardless of the volume injected at a visit; a 10 mL vial therefore supports 10 units. The record should identify each vial's allergens, concentration, volume, preparation date, and supervising physician. When administered, injections are reported separately with 95115 for one injection or 95117 for two or more. CMS assigns substantially more practice-expense RVUs to this service in the office than in a facility.

95165 billing questions
How many units should be billed for a multidose vial?
Medicare counts one unit per 1 mL aliquot from the vial: a 5 mL vial supports 5 units, and a 10 mL vial supports 10. The volume injected at each visit does not change that count.
Can 95165 be billed on the same day as an injection code?
Yes, when extract preparation and administration both occur that day. Report preparation with 95165 and administration with 95115 for one injection or 95117 for two or more.
What if the allergist prepares the extract but another physician gives the shots?
The preparing practice reports 95165 for the doses prepared. The administering practice reports 95115 or 95117 for injections it gives, rather than reporting 95165 for extract it did not prepare.
Should the complete-service codes 95120 through 95134 be used for Medicare patients?
No. Medicare does not recognize those combined injection-and-extract codes. Report the appropriate injection and antigen preparation codes separately when both services are furnished.
When is 95144 used instead of 95165?
Use 95144 for extract prepared in single-dose vials. Use 95165 for extract prepared in multidose vials, with units based on the doses the vials contain.
Can an E/M visit be billed on an injection day?
A separately identifiable evaluation of new symptoms may be reported when it goes beyond routine injection screening and is documented. Append modifier 25 to the E/M code.
