Primary tumor staging.

Comments

Practices were required to report clinical and staging data associated with each beneficiary’s assigned cancer. Primary Tumor (T) describes the size and/or the extension of the primary tumor specifically defined for each cancer site. Generally, the higher the Primary Tumor category (value), the greater the extent of the disease and generally the worse the prognosis; some exceptions exist. Primary tumor reporting was required for breast cancer, female GU other than ovarian cancer, gastro-esophageal cancer, kidney cancer, malignant melanoma, ovarian cancer, pancreatic cancer, and prostate cancer, and for the following cancer types for specific diagnosis codes:
