CS Lymph Nodes--Breast: Are small isolated tumor emboli occasionally found in lymph node capsular or pericapsular lymphatics sufficient to code as a lymph node metastasis?
CS Site Specific Factor--Prostate: How is SSF 6 coded for this site when there is only one Gleason number documented and the number is less than 5 (e.g., Gleasons 3)?
CS Extension--Colon: What is the difference between codes 46 [Adherent to other organs or structures, but no microscopic tumor found in adhesion(s)] and 57 [Adherent to other organs or structures, NOS]? See Discussion.
CS Tumor Size/CS Eval--Breast: How are these fields coded when there is a clinical size recorded but the tumor size is not specified on the pathology report associated with a subsequent resection? See Discussion.
CS Site Specific Factor 4--Prostate: For apex involvement at prostatectomy, is only apical involvement found at prostatectomy included or is all histologically proven apical involvement documented in the second digit of Site Specific Factor 4? See Discussion.
CS Lymph Nodes--Breast: Clarify the use of code 25 [Movable axillary lymph node(s), ipsilateral, positive with more than micrometastasis (i.e., at least one metastasis greater than 2 mm)] vs code 60 [Axillary/regional lymph node(s), NOS; Lymph nodes NOS] when surgically removed lymph nodes are positive but the size of the metastasis is not stated. See Discussion.
CS Extension/EOD Extension--Renal Pelvis: Primary site is renal pelvis with direct extension to the rt adrenal gland. What is the correct extension code?
CS Extension--Brain and CNS: How is this field coded for a malignant tumor presenting as a confluent lesion over right parietal, posterior frontal and thalamic regions?
