E/M with 96372

When we do our quarterly visits for our psoriasis patients and administer an injection of a biologic in the office, is it ok to bill both office visit (such as 99213) with the injection of a biologic code, 96372. Or, should we only bill the 96372? We would be checking their skin for response to treatment, getting history on side effects and psoriasis and/or arthritis as well.

A/P would include Psoriasis and Long term use of medications +/- itch, xerosis, etc if appropriate.

Thanks,

Danielle
