Summary & Overview
CPT 3300F: Cancer Staging Documentation Using AJCC
CPT code 3300F identifies a documented AJCC cancer stage when a provider diagnoses a patient with cancer. Capturing the AJCC stage in the medical record supports clinical decision-making, care coordination, and quality measurement; it also informs prognosis and treatment planning at a national level. Accurate use of the code contributes to standardized cancer staging documentation across care settings.
Key payers in scope for national reporting and coverage considerations include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Payer policies may affect documentation expectations and claims processing for staging-related services.
Readers will find a concise overview of what 3300F represents, the clinical context for its use in oncology settings, and what documentation elements are relevant for coding. The publication describes benchmarking and policy topics commonly associated with staging documentation—such as consistency of AJCC use, implications for quality measurement, and intersections with oncology care pathways—while noting where input data are not available. This resource is aimed at clinicians, coding professionals, and policy analysts seeking a clear national-level summary of CPT code 3300F and its role in cancer staging documentation.
Billing Code Overview
CPT code 3300F is used when a provider diagnoses a patient with cancer and documents the cancer stage using the American Joint Committee on Cancer (AJCC) classification system. The code indicates that the clinician has reviewed and recorded the AJCC stage as part of the diagnostic and staging process.
Service type: Cancer staging documentation and review
Typical site of service: Oncology clinic, hospital outpatient department, or inpatient oncology service

Clinical & Coding Specifications
Clinical Context
A 62-year-old patient presents to an oncology clinic after biopsy-confirmed invasive ductal carcinoma of the breast. The medical oncologist performs a comprehensive staging review using the American Joint Committee on Cancer (AJCC) classification to document tumor size (T), nodal status (N), and distant metastasis (M), incorporating pathology reports, imaging (breast MRI, chest CT, bone scan), and clinical exam findings. The provider documents the AJCC stage group (for example, Stage IIIB) in the medical record and updates the problem list and treatment planning notes. This staging documentation is used to guide systemic therapy decisions, surgical planning, radiation indications, and to support prior authorization and oncology quality reporting. Typical workflow steps include chart review of pathology and imaging, multidisciplinary tumor board discussion when applicable, documentation of the AJCC edition used, and communication of stage to the patient and care team.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
25 | Significant, separately identifiable evaluation and management service by the same physician on the same day of a procedure | Use when a distinct E/M visit is performed and documented on the same date as the staging documentation procedure. |
| 57 | Decision for surgery | Use when the staging assessment directly results in the decision to proceed to an operative procedure on the same day.
