Summary & Overview
HCPCS Level II S0164: Injection, Pantoprazole Sodium 40 mg
HCPCS Level II code S0164 denotes administration of pantoprazole sodium 40 mg by injection, used to provide parenteral proton-pump inhibitor therapy in acute and outpatient settings. Nationally, injectable pantoprazole is important for short-term management of acid-related conditions when oral administration is not feasible or when rapid acid suppression is needed. The code captures the drug product and administration for billing and utilization tracking.
Key payers in scope include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for parenteral pantoprazole, common sites of service, and typical billing considerations. The publication outlines benchmark elements and policy-relevant points affecting coverage and coding practice, including where injectable therapy is commonly billed and how the HCPCS Level II classification informs payer processing.
This summary provides practical orientation for revenue cycle, clinical pharmacy, and coding teams on how S0164 is used, what settings most commonly generate the code, and which major payers routinely adjudicate claims involving injectable pantoprazole. Data not available in the input will be noted in relevant detail sections.

Clinical & Coding Specifications
Clinical Context
A 58-year-old hospitalized patient with a history of severe gastroesophageal reflux disease (GERD) and a recent inability to tolerate oral medications due to postoperative ileus requires intravenous acid suppression. The admitting team orders an IV bolus of pantoprazole sodium 40 mg for short-term gastric acid control and prevention of stress-related mucosal bleeding. The medication is administered by a registered nurse in an inpatient acute care setting (medical ward or post-anesthesia care unit) following pharmacy verification and electronic medication administration record (eMAR) documentation. The workflow includes order entry by the attending physician, pharmacist preparation and dispensing of S0164 (injection, pantoprazole sodium, 40 mg), bedside administration by nursing, and documentation of dose, route (IV), and patient response. Typical monitoring includes assessment for local injection-site reactions, evaluation of symptom relief or reduction in gastric acidity-related complications, and review of relevant labs (electrolytes, liver function tests) as clinically indicated.
