MP/H Rules/Histology--Head & Neck: Please clarify rule H3. The first statement is "Do not code terms that do not appear in the histology description". The second statement is "Do not code...unless the words...appear in the final diagnosis"

One of our pathology labs frequently will state "keratinizing squamous cell" in the microscopic description (histologic description), but only state "squamous cell carcinoma" in the final diagnosis. May we code from the histologic description if it's not in the final diagnosis?

Date of diagnosis--Diagnostic confirmation: How are the diagnosis date and diagnostic confirmation coded when the pathology (needle biopsy followed by resection) reports GIST, NOS and the physician subsequently states this is a malignant GIST and treats the patient for a malignancy? See Discussion.

First course treatment--Breast: When Lupron is given as cancer-directed treatment for metastatic breast cancer, should it be coded as Hormone Therapy or Other Therapy? See Discussion.

Primary Site--Lung: What are the guidelines for coding primary site when a lung tumor is described as a hilar mass? See discussion.

Surgery of Primary Site--Breast: How should the Surgery of Primary Site field be coded when a patient has a lumpectomy and an additional margin excision during the same procedure? See discussion.

MP/H Rules/Histology--Thyroid: When is 8341/3, papillary microcarcinoma coded? The code description in ICD-O-3 is followed by (C739), yet there are two SINQ answers that tell us specifically to not use this code for thyroid primaries. Even the first revision of ICD-O-3 still carries the (C739) as part of this code, which goes against SINQ 20110027 and 20081127.

Grade--Bladder: Do you use the grade stated on the pathology report for coding the grade/differentiation field for bladder and renal pelvis field? See discussion.

MP/H Rules/Histology--Skin: How is histology coded for an "endocrine mucin-producing sweat gland carcinoma with transformation to mucinous carcinoma"? See Discussion.

Reportability/Primary site--Skin: Is a basal cell carcinoma of the lip "ever" reportable and if so, what would need to be documented or seen?  See discussion.

Reportability/Histology--Pancreas:  Is well-differentiated neuroendocrine tumor (M8240/3) as stated on a pathology report reportable or can the clinical information be used as an adjunct to the path report, which further states the specific type of neuroendocrine tumor is an Insulinoma, therefore, NOT reportable (M8151/0)? See discussion.
