Final answer:
In the CPT manual, the removal of skin tags includes local anesthesia. For home administration of antimicrobials to treat systemic infections, oral administration is most convenient and appropriate.
Step-by-step explanation:
According to the CPT manual, skin tag codes include local anesthesia. This means that when skin tags are removed, local anesthesia is typically used to numb the area around the skin tag. It is important for patient comfort and to minimize pain during the procedure. When considering routes of administration for the home administration of an antimicrobial to treat a systemic infection, the most appropriate and convenient option would likely be oral administration. Intravenous administration requires special equipment and training, whereas oral administration involves taking medication by mouth, which is easy and convenient for most patients to do at home.
