Summary & Overview
HCPCS G9855: Patients Who Died From Cancer
HCPCS Level II code G9855 designates records for patients who died from cancer. The code captures mortality outcomes related to cancer diagnoses and is relevant for hospital inpatient and hospice documentation, clinical quality measurement, and administrative reporting. Nationally, consistent use of this code supports public health surveillance, quality measurement, and end-of-life care monitoring for oncology populations.
Key payers discussed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication provides a concise view of coding context, payer coverage considerations, and the clinical setting for use of the code. Readers will find benchmarks and policy context where available, a summary of typical sites of service and service type, and notes on common payer expectations for reporting mortality-related encounters. The summary highlights areas where data are present versus where input was not provided.
This piece is intended for coding professionals, compliance staff, and policy analysts seeking a national overview of the code's purpose, typical use settings, and payer scope. Data not available in the input is noted where details such as associated taxonomies, specific ICD-10 mappings, and related codes are not provided.
Billing Code Overview

Clinical & Coding Specifications
Clinical Context
A patient with advanced metastatic cancer has expired in an inpatient hospice or hospital setting. The clinical workflow begins when the treating oncology team notifies medical records and the hospital billing office of the death. The patient’s encounter record is closed, and final diagnoses are reviewed to identify the underlying malignant neoplasm and any terminal events (e.g., respiratory failure, sepsis). Documentation of death, attending physician verification, and completion of the medical certificate of death are required. Coding staff assign the appropriate cause-of-death diagnoses and apply the HCPCS Level II code G9855 to denote the encounter category “Patients who died from cancer” for reporting, registry, or quality measurement purposes. Relevant supporting documentation includes the death note, discharge summary, pathology reports, and end-of-life orders. Typical sites of service include inpatient hospital units, inpatient hospice facilities, and acute inpatient rehabilitation units when death occurs during an active admission.
