Summary & Overview
HCPCS S0032: Injection, Nafcillin Sodium, 2 g
HCPCS Level II code S0032 identifies administration of nafcillin sodium, 2 grams, a parenteral antibiotic used for serious gram-positive infections. This code is relevant nationally for hospitals, emergency departments, and infusion centers that provide intravenous antimicrobial therapy. Accurate coding of S0032 supports proper claims processing, utilization tracking, and clinical documentation for high-acuity infectious disease treatment.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for nafcillin use, typical sites of service, and common billing considerations. The publication also highlights benchmarks and payment policy updates where available, plus coding relationships that affect service lines and revenue reporting.
The content is organized to help reimbursement managers, coding professionals, and clinical leaders understand where S0032 fits in outpatient and inpatient antibiotic administration workflows, what to expect from major payers, and which operational areas (administration setting, documentation, and service line classification) are most impacted. Data not available in the input is noted where applicable.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult hospitalized for a serious gram-positive bacterial infection (for example, methicillin-sensitive Staphylococcus aureus bacteremia, surgical site infection, or complicated skin and soft tissue infection) requiring intravenous anti-staphylococcal penicillin therapy. The patient presents with fever, leukocytosis, localized signs of infection, and positive blood or wound cultures showing nafcillin-susceptible organisms. The admitting team (hospitalist, infectious disease consultant, or surgeon) orders S0032 for administration of nafcillin sodium 2 grams IV, dosed every 4 to 6 hours based on renal function and clinical status.
The clinical workflow: orders for IV nafcillin are entered in the electronic health record; pharmacy verifies dose and prepares the 2 gram vial or syringe; nursing administers the medication via IV push or infusion per facility protocol; vital signs and infusion-site checks are documented; therapeutic response and adverse effects (eg, allergic reaction, nephrotoxicity) are monitored. Documentation includes indication, dose, route, time of administration, lot number, and the administering clinician/nurse. Billing uses S0032 for the drug supply when appropriate, with accompanying facility or administration codes billed per payer rules.
