CS Lymph Nodes--Breast: How is this field to be coded if the pathologist staged the case pN1a and the lymph node is stated to be negative on H&E, is .3 cm on IHC stain for pancytokeratin but on review of smears shows no malignant cells?
CS Eval--Prostate: How is CS Ts/Ext Eval to be coded for a clinically inapparent prostate cancer that is treated with Lupron and a subsequent prostatectomy? See Discussion.
CS Tumor Size--Breast: Should this field be coded to 999 [Unknown] or 008 [0.8 cm tumor] when the tumor size is not provided on a stereomammotomy biopsy for an in situ malignancy and a subsequent excision demonstrates 0.8 cm tumor of residual in situ disease?
CS Tumor Size/CS Site Specific Factor--Breast: Should the tumor size be coded to 1.5 cm or 2.5 cm and SSF6 coded to 020 or 030 respectively for a tumor with invasive and in situ components described as being a 2.5 cm tumor with a "greater than" 1.5 cm invasive portion? See Discussion.
CS Tumor Size--Breast: How is this field coded for a 1.5 cm clinically palpable tumor that appeared to be a cyst with a papilloma when the partial mastectomy Path Micro stated the lesion was an "intraductal papilloma with focal noninvasive papillary carcinoma"? See Discussion.
CS Lymph Nodes--Colon: What criteria is used to distinguish between code 30 [Regional lymph nodes, NOS] and 80 [Lymph nodes, NOS] when positive lymph nodes are removed during a colon resection but the lymph node location is not stated? See Discussion.
CS Site Specific Factor--Melanoma: What is the correct code for measured thickness in SSF 1 for a melanoma of the choroid without an enucleation? See Discussion.
CS Site Specific Factor/Melanoma: How is CS SSF1 (depth of invasion) coded for a melanoma that demonstrates dermal invasion to a depth of "less than .2 mm" be coded to 999 [unknown]? See Discussion.
CS Lymph Node Examined--Lung: How is this field coded when a mediastinoscopy and lobectomy are performed and the pathology report indicates multiple lymph node fragments were removed as biopsy specimens and the lobectomy specimen revealed 3 interlobar lymph nodes?
Scope of Regional Lymph Node Surgery/CS Reg LN Pos/Exam: How are these fields coded if the operative report does not mention a separate lymph node procedure at the time of the surgery to the primary site? See Discussion.
