Summary & Overview
HCPCS G9435: Aspirin Prescribed at Discharge
HCPCS Level II code G9435 indicates that aspirin was prescribed to a patient at the time of discharge. Nationally, this code is used to capture a discrete, clinically meaningful discharge intervention — provision of an antiplatelet medication — that can be relevant to transitions-of-care measures, secondary prevention after cardiovascular events, and quality reporting efforts. The code’s presence in claims can signal adherence to guideline-based discharge medication reconciliation and secondary prevention protocols.
Key payers in the coverage landscape include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the code’s clinical context, common sites of service where it appears, and the types of benchmarks and policy topics typically associated with discharge medication codes. The publication summarizes benchmarking approaches, reimbursement and coding considerations, and how G9435 is used in quality measurement and claims-based performance tracking.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult admitted for acute myocardial infarction or unstable angina who is clinically stable at hospital discharge. After inpatient stabilization and completion of necessary interventions (such as percutaneous coronary intervention when indicated), the discharging clinician prescribes low‑dose aspirin for secondary prevention of atherosclerotic cardiovascular disease and to reduce risk of recurrent ischemic events.
The clinical workflow includes inpatient evaluation by cardiology and hospital medicine teams, medication reconciliation prior to discharge, documentation of the aspirin prescription in the discharge summary and electronic health record medication list, patient counseling on dosage and adherence, and communication of the discharge medication to the primary care clinician and outpatient cardiologist for follow‑up. The service represented by G9435 indicates that aspirin was prescribed at discharge as part of care transitions for a patient with an ischemic heart disease indication.
