Summary & Overview
HCPCS G9134: Non-Hodgkin's Lymphoma, Stage I–II, Not Relapsed
HCPCS Level II code G9134 designates disease status for non-Hodgkin's lymphoma at initial diagnosis when classified as stage I or II and not relapsed or refractory. The code is intended for use within a Medicare-approved demonstration project, reflecting targeted reporting or program evaluation rather than routine billing across all settings. Nationally, such demonstration-specific codes matter because they enable measurement of outcomes and resource use in pilot programs that can inform broader oncology policy and payment design.
Key payers addressed in this publication include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical context and service expectations tied to the code, where it is typically used, and what elements are available in the input. The piece outlines how G9134 fits into oncology service lines and ambulatory cancer-care sites, and it notes where input data are missing.
This summary prepares clinicians, billers, and policy stakeholders to interpret the code's purpose within demonstration projects, understand payer relevance, and identify areas where additional documentation or policy detail would be needed for broader adoption or analysis. Data not available in the input are clearly indicated for transparency.
Billing Code Overview
HCPCS Level II code G9134 describes an oncology disease-status designation for non-Hodgkin's lymphoma at initial presentation: stage I or II at diagnosis, not relapsed, not refractory. The code is specified for use within a Medicare-approved demonstration project, indicating a focused programmatic context rather than routine national claims reporting.
Service Type: Oncology — disease status assessment / reporting
Typical Site of Service: Hospital outpatient departments, oncology clinics, and other ambulatory cancer-care settings participating in demonstration projects

Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with newly diagnosed non-Hodgkin's lymphoma, cellular classification unspecified, presents for initial staging and disease-status documentation under a Medicare-approved demonstration project. The patient has stage I disease at diagnosis, has not relapsed, and is not refractory to prior therapy. The clinical workflow begins with oncology intake and history review, physical examination, and review of pathology and imaging studies (CT, PET/CT) to confirm stage. The oncology team documents disease status (stage I or II), performance status, and treatment intent in the medical record. Multidisciplinary discussion may occur with radiation oncology and hematology/oncology to plan first-line therapy. Billing for the demonstration-project–specific service is captured with G9134 after documentation confirms the disease stage and that the case meets demonstration project inclusion criteria. Typical site of service is an outpatient oncology clinic, multidisciplinary cancer center, or hospital outpatient department. Common patient encounters include new-patient consultation visits, staging visits, tumor board documentation, and care-plan encounters where the documented disease status is required for project reporting.
