AIClinical Context

Clinical Description

This code represents the administration of 2 grams of nafcillin sodium, an antibiotic medication. Nafcillin is a penicillinase-resistant penicillin used to treat infections caused by susceptible staphylococci, including methicillin-sensitive Staphylococcus aureus (MSSA). It is typically administered intravenously.

When to Use

This code is used when 2 grams of nafcillin sodium are administered to a patient for the treatment of bacterial infections. Documentation should clearly indicate the drug administered, the dosage (2 grams), and the route of administration (e.g., IV infusion). This often occurs in inpatient or outpatient hospital settings, or infusion centers.

Coding Tips

Ensure the documentation specifies the exact dosage of 2 grams; other dosages would require a different code or unit calculation.

This code represents the drug itself, not the administration service. A separate CPT code for the infusion or injection service will also be required.

Verify the medical record confirms the administration of nafcillin sodium, not another penicillinase-resistant penicillin.
