Summary & Overview
HCPCS G2205: Pregnancy During Adjuvant Treatment Course
HCPCS Level II code G2205 identifies patients who are pregnant during an adjuvant treatment course. This administrative marker is used in oncology and related specialty care to record pregnancy status that may influence adjuvant therapy decisions, care coordination, and monitoring. Nationally, accurate capture of pregnancy during adjuvant treatment is important for patient safety, quality measurement, and appropriate clinical documentation.
Key payers in typical analyses include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of how G2205 is defined and applied in clinical settings, what payers commonly consider in coverage and claim adjudication, and contextual information about where this code is used (oncology outpatient clinics, infusion centers, and related specialty sites). The publication highlights benchmarks and policy-relevant considerations where available, and clarifies where input data are not provided. This summary is intended for providers, billing staff, and policy analysts seeking a concise national view of the code’s clinical purpose, payer landscape, and reporting implications.

Clinical & Coding Specifications
Clinical Context
A 32-year-old pregnant patient is receiving adjuvant systemic therapy (chemotherapy) after surgical treatment for early-stage breast cancer. During routine oncology follow-up the multidisciplinary team documents pregnancy during the adjuvant treatment course, requiring care coordination between medical oncology, maternal–fetal medicine, and the oncology nursing team. The workflow includes confirming pregnancy with obstetric ultrasound, medication reconciliation to stop teratogenic agents, counseling on risks, adjusting or delaying adjuvant therapy as clinically indicated, enhanced fetal monitoring, documentation of pregnancy status in the oncology treatment chart, and communication with payer for coverage implications. Billing staff append the pregnancy-specific HCPCS level II code G2205 on claims to indicate the patient has pregnancy during an active adjuvant treatment course so that care managers and payers can process concurrent obstetric and oncology services appropriately.
