Summary & Overview
HCPCS G9850: Multiple Emergency Department Visits in Last 30 Days of Life
HCPCS Level II code G9850 denotes that a patient had more than one emergency department visit in the last 30 days of life. As a utilization measure tied to end-of-life care, this code highlights acute-care use during a critical period and is relevant for quality measurement, care coordination, and claims-based research. Nationally, tracking repeat emergency visits near death informs policy debates about inpatient versus palliative approaches and identifies opportunities for advance care planning and community-based supports.
Key payers included in the analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for G9850, common billing considerations, and what to expect in payer coverage policies. The publication summarizes benchmarks where available, outlines typical sites of service and service types associated with the code, and notes areas where input data is not available.
The content is intended for hospital billing teams, palliative care clinicians, policy analysts, and payers seeking to understand how repeated emergency department use at the end of life is represented in claims. It does not provide clinical recommendations but presents the code’s purpose, reporting context, and what users can expect to find in accompanying analytical sections.

Clinical & Coding Specifications
Clinical Context
A patient with a life-limiting terminal illness (for example advanced metastatic cancer, end-stage heart failure, or progressive neurodegenerative disease) presents to the emergency department multiple times in the last 30 days of life. Typical workflow: the patient arrives via ambulance or private transport for acute symptoms such as uncontrolled pain, dyspnea, altered mental status, or dehydration. The ED team evaluates, stabilizes, and documents each visit, including medications given, advance directives reviewed, and palliative care or hospice consults requested. For hospice-enrolled patients, the visits often reflect escalating symptom burden or unstable home support; for non-hospice patients, ED visits may trigger inpatient admission or direct referral to palliative care services. Billing staff assign the HCPCS Level II code G9850 when the patient had more than one ED visit in the last 30 days of life, ensuring that documentation supports timing of visits and terminal prognosis in the medical record.
