Update to Current Manual/Surgery of Primary Site 2023--Melanoma: Considering the 2023 melanoma surgery codes for punch biopsy NOS (B220) and shave biopsy NOS (B230), how is Date of First Surgical Procedure coded when the punch or shave biopsy is not excisional? See Discussion.
Reportability/Histology--Thyroid: Is a diagnosis of papillary carcinoma, follicular variant, encapsulated/well demarcated, non-invasive reportable? See Discussion.
Solid Tumor Rules/Multiple Primaries--Lung: How many primaries and what M Rule applies to a 2022 diagnosis of right upper lobe non-small cell lung carcinoma (NSCLC) when the patient has a history acinar adenocarcinoma in the right lower lobe of the lung in 2020, followed by squamous cell carcinoma in the right middle lobe of the lung in 2021? See Discussion.
Primary site: Is there a physician priority list for coding primary site? For example, the surgeon states during a pancreatectomy that the primary is in body while the pathologist states in their synopitc report that primary is neck; neither is in agreement, or neither is available for confirmation.
Histology--Vulva: How is the histology coded for vulvar intraepithelial neoplasia III (VIN III)/Squamous cell carcinoma in situ from a pathology report of the vulva, 8070/2 for squamous cell carcinoma in situ or 8077/2 for VIN III? The rules do not discuss this particular situation.
Solid Tumor Rules/Multiple Primaries--Peripheral Nerves: How many primaries should be abstracted, and which M Rule applies, when a malignant peripheral nerve sheath tumor (MPNST) in the right arm (C471) is followed greater than one year later by a separate malignant peripheral nerve sheath tumor of the thoracic chest wall (C473)? See Discussion.
Solid Tumor Rules/Multiple Primaries--Prostate: How many primaries should be abstracted, and which M rule applies when a patient is diagnosed with intraductal carcinoma of the prostate on biopsy followed by invasive adenocarcinoma on radical prostatectomy more than 60 days later? See Discussion.
Histology--Cervix: Can human papilloma virus (HPV) or p16 testing results from a non-reportable high-grade squamous intraepithelial lesion (HSIL)/cervical intraepithelial neoplasia (CIN 3) pathology report be used to code histology as squamous cell carcinoma (SCC), HPV-positive (8085), if subsequent excision/resection identifies invasive SCC and no further HPV or p16 testing is done on the invasive specimen? See Discussion.
SEER Manual/Reportability--Brain and CNS: Is microadenoma reportable? A pituitary mass seen on imaging was "consistent with Microadenoma" on 11/15/2022. There was no histologic confirmation or treatment given.
