Summary & Overview
HCPCS G8579: Antiplatelet Medication at Discharge
HCPCS Level II code G8579 documents the prescription or documentation of an antiplatelet medication at hospital discharge. Nationally, accurate capture of discharge medications is a key quality measure tied to secondary prevention of cardiovascular events and to transitions-of-care reporting. Use of G8579 facilitates standardized reporting of antiplatelet therapy at discharge following ischemic cardiovascular events or procedures where antiplatelet agents are indicated.
Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for discharge antiplatelet therapy, typical sites of service, payer coverage considerations, and the benchmarks commonly used to assess discharge medication reconciliation and adherence to guideline-directed secondary prevention. The publication also summarizes coding nuances, billing implications, and relevant quality-reporting contexts where G8579 is used.
This summary provides national-level context useful for billing, compliance, and care-coordination teams seeking to align documentation and claims with established quality measures for antiplatelet therapy at discharge.

Clinical & Coding Specifications
Clinical Context
A typical patient is a 68-year-old male admitted with an acute ischemic stroke or an acute coronary syndrome who undergoes inpatient evaluation and treatment and is being prepared for discharge. During the inpatient stay the patient received interventions that include neurovascular or cardiac evaluation and stabilization, and the care team documents the need for ongoing antiplatelet therapy to reduce risk of recurrent arterial thrombosis. At discharge the hospital documents the prescription and counseling for an antiplatelet medication such as aspirin or clopidogrel, and assigns billing code G8579 to indicate that an antiplatelet medication was prescribed at discharge. The clinical workflow includes medication reconciliation, assessment of contraindications (active bleeding, allergy), selection of agent and dose, patient education on adherence and adverse effects, and transmission of the prescription to the outpatient pharmacy. The discharge summary and medication list in the electronic health record are updated and communicated to the primary care provider and cardiology or neurology follow-up services.
