EOD 2018/EOD Primary Tumor--Cervix: How is Extent of Disease (EOD) Primary Tumor of the cervix coded when it invades into the bladder on surgery and noted as T4. No further information is provided, and it is not possible to contact the physician for clarification. Would you code 550 (Bladder wall; bladder, NOS excluding mucosa), 750 (Bladder mucosa), or 999 Unknown?
Reportability--Brain and CNS: Is an optic nerve meningioma reportable if stated to arise in the “intraorbital segment” of the optic nerve meninges? See Discussion.
First course treatment--Kidney: How should the different treatment fields be coded if surgery is planned but cancelled due to patient noncompliance, then the tumor is treated with ablation, and eventually surgery is given due to residual disease? See Discussion.
Update to Current Manual/Race: For the Example #15 under Race Coding Examples in the 2024 SEER manual, could coding these as 97 result in an under-reporting of Native Hawaiians? See Discussion.
Solid Tumor Rules/Multiple Primaries--Brain and CNS: How many primaries are accessioned, and what M Rule applies to a 2023 diagnosis of pituitary macroadenoma followed by a 2024 diagnosis of pituitary neuroendocrine tumor (PitNET) when the patient did not undergo surgery, but did undergo hormone therapy with Cabergoline? See Discussion.
Solid Tumor Rules/Histology--Bladder: How is histology coded for a bladder tumor when the diagnosis is 95% large cell neuroendocrine carcinoma and 5% high grade urothelial carcinoma of no special type? See Discussion.
Solid Tumor Rules--Urinary: The example used in Rule M15 of the Urinary Solid Tumor Rules refers to the same row in Table 3. Should the example say Table 2 since Table 3 is non-reportable urinary tumors. See Discussion.
SEER Manual/Reportability--Skin: Is keratoacanthoma (8071/3) of the skin reportable? This code is also for squamous cell carcinoma (SCC), keratinizing. In the 2024 SEER manual, 8071/3 falls under the not reportable section of skin (outside of specific sites).
Solid Tumor Rules/Multiple Primaries--Stomach: Is a carcinoid tumor of the stomach diagnosed on 01/01/2023, on a patient who was followed up by Gastrointestinal (GI) and was found to have another stomach carcinoid on 02/01/2024, one primary or two? See Discussion.
