Summary & Overview
HCPCS G9826: Patient Transferred After Initiation of Chemotherapy
HCPCS Level II code G9826 denotes the transfer of a patient to a practice after chemotherapy has already been initiated. The code captures a specific transition point in cancer care when treatment is started by one provider or setting and responsibility for ongoing management moves to another practice. Nationally, documenting transfers accurately supports continuity of care, appropriate billing for subsequent treatment encounters, and clear clinical communication across oncology teams.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of what the code represents, the clinical and administrative context for its use, and the typical service settings where it applies. The publication summarizes common payer perspectives and documentation expectations, offers benchmarks related to utilization and coding consistency where available, and highlights relevant policy or billing guidance affecting transitional oncology care.
This summary is written for a national audience of clinicians, practice managers, and billing professionals seeking clear guidance on the purpose and operational context of HCPCS Level II code G9826. Data not available in the input is noted where applicable.

Clinical & Coding Specifications
Clinical Context
Patient is a 58-year-old woman with newly diagnosed stage IIIB breast cancer who began systemic chemotherapy at a tertiary oncology center while her primary oncologist was unavailable. After initiation of therapy (first infusion administered and treatment plan established), the patient is transferred to the receiving oncology practice for ongoing chemotherapy administration, follow-up management, and supportive care. The receiving practice performs medication reconciliation, documents prior treatment administered, verifies dosing and adverse events, completes baseline labs and toxicity assessments, and schedules subsequent infusion appointments. Typical workflow includes review of the initial chemotherapy regimen and infusion record, assessment of performance status and laboratory results (CBC, CMP), verification of central venous access or port status, discussion of prior reactions, and coordination of chemotherapy order transfer and scheduling. Typical nursing activities include triage, education on self-care and delayed toxicities, and documentation of prior cycle dates. Typical practitioners involved are medical oncologists, infusion nurses, and oncology pharmacists. Typical setting is an outpatient oncology clinic or infusion center where the patient continues systemic chemotherapy following transfer of care.
