Is it appropriate to use Z79.899 to account for Benadryl taken 30-minutes prior to presentation when a patient is having an allergic reaction (rash) to food ingested. This patient has a history of an allergy to the same food and the medication is NOT listed on the patients long-term (current) medication list.
When looking in the index under prophylactic >medication > Z79.899; however, the tabular states Other long term (current) drug therapy.
I understand this code is not used for antibiotics given short term for bronchitis; however, when reviewing the ICD-10 Appendix C: Pharmacology List, there are several drugs listed as "prophylaxis" (i.e. an inhaled corticosteroid Z79.51 for an asthma exacerbation) it may not be used daily, but it was used prior to presenting. Since the patient has a diagnostic history that the medication is treating, is it appropriate to use Z79.899.
