Reportability--Brain and CNS: Does a neurofibroma actually arise in peripheral nerve roots like a schwannoma even if it is referred to as a "C6-T1 intradural spinal cord tumor" and is therefore not reportable?
Cell indicator--Lymphoma: If the primary site for a lymphoma is stated to be the lymph nodes but there is no biopsy of a lymph node, can the immunophenotype designation for a lymphoma be coded based on a bone marrow or liver biopsy indicating "diffuse large B-cell lymphoma"?
Reportability/Histology: Is a case reportable if the Final Diagnosis in a pathology report indicates a non reportable diagnosis but the Diagnosis Comment on the same report indicates a non reportable diagnosis followed by a reportable diagnosis in parenthesis? See Discussion.
MP/H Rules--Urinary: How many primaries are abstracted when a patient has a May 2000 invasive papillary transitional cell carcinoma of the bladder, a November 2004 invasive papillary transitional cell carcinoma of the right ureter and a May 2007 urothelial carcinoma in situ of both the left and right ureters?
Multiplicity Counter--Breast: How should the multiplicity counter be coded for a 3.8 cm infiltrating duct carcinoma with two "satellite nodules" measuring 5 mm and 7mm that are not described as either metastases or multiple foci?
Radiation Therapy--Prostate: Is the regional treatment modality XRT best coded to 50 (brachytherapy, NOS), 53 (LDR) or 54 (HDR) when the documentation indicates only "I-125 seeds" to the prostate?
Multiplicity Counter-Breast: The general instructions say to ignore separate microscopic foci when determining when to use the single tumor or multiple tumor modules. Do these instructions apply if sizes are given for the foci? See Discussion.
