Type of Multiple Tumors--Lung: Is this field coded to 40 [Multiple invasive] or 80 [Unk in situ or invasive] when only one nodule is biopsied of multiple existing nodules for a reported single lung primary? See Discussion.
Radiation Sequence with Surgery--Head & Neck: How is this field coded for a tonsil primary diagnosed on 4/16/07 by a regional lymph node FNA when the patient subsequently initiates radiation on 5/8/07 and has a tonsillectomy with neck dissection on 7/30/07?
Date of Diagnosis: When a 4/04 clinical impression indicates the appearance of a carcinoma that is contradicted by a negative 4/04 biopsy but is confirmed by a 5/04 resection, should the diagnosis date be coded to April or May? See Discussion.
Date of diagnosis--Breast: How is the date of diagnosis coded when a mammogram describes only "suspicious calcifications" with a BIRADS category of 4 assigned and the suspicious calcifications are subsequently proven to be malignant on biopsy? See Discussion.
