EOD follows AJCC criteria in this situation and we have confirmed with AJCC that Stage T2a (superficial muscle) and Stage T2b (deep muscle) cannot be assigned when only a TURB is done.

For EOD Primary Tumor, Bladder, codes 200, 250, 300, 350, can only be used when

• Cystectomy is performed
• Muscularis propria is involved, AND
• Pathology report states superficial muscle (200, 250) or deep muscle (300, 350) is involved

If a TURB is done and there is mention of the muscularis propria invasion (superficial muscle or deep muscle), use EOD codes 370 or 400. If a TURB is done and the pathology report states superficial or deep muscle, ignore and coded as “invasion of muscularis propria, NOS” (EOD codes 370 or 400).

Instructions and code descriptions for EOD Primary Tumor have been updated to indicate this. These updated instructions and code descriptions will be available when SEER*RSA is updated for 2024, Version 3.1 (Sept/Oct 2023). These updates are included here for reference and can be applied for cases diagnosed 2018+.

Assign the neoadjuvant therapy data items as if the patient had neoadjuvant therapy.  Neoadjuvant Therapy data item would be coded either code 1 or 2 depending on whether the chemotherapy was completed or not. In this case, they are a surgical candidate by having the chemotherapy with the plan from the beginning to evaluate the chemotherapy after X cycles to see if surgery can be performed. After the patient is evaluated, update the abstract as needed.

Assign code 8 for Neoadjuvant Therapy--Clinical Response and assign a code 9 for Neoadjuvant Therapy--Treatment Effect when the treatment is still in progress. Revise these codes after the treatment has been completed.

We will update the manual to include these instructions.

Change to current instructions. We will update this example in the next edition of the manual. The new example will instruct registrars to look for other descriptions of the patient’s race. When no other information is available, assign 07, Native Hawaiian, in Race 1 and assign 97, Pacific Islander, NOS in Race 2. Begin following this new instruction now.

Assign code 01 (White) for Hispanic when there is no additional information. It is listed in the 2024 SEER Manual, Race Coding Instruction 6.b.i. and in Appendix D for code 01. We will remove Hispanic from the list in Appendix D under code 99 in the next version of the manual.

Report biliary intraepithelial neoplasia (dysplasia), high grade. As noted in SINQ 20240021 and the Other Sites Solid Tumor Rules, Rules H4/H26, the listed sites may not include all reportable neoplasms for 8148/2.

We will update the Other Sites Solid Tumor Rules to reflect this code as well as make revisions in the next release of the SEER Manual.

Do not report PanIN II. WHO Classification of Digestive Tumors, 5th edition, now categorizes PanIN into two categories, low grade (8148/0) and high grade (8148/2). PanIN grade I and PanIN grade II are categorized as PanIN low grade; PanIN grade III is categorized as PanIN high grade.

We will update the Reportability section of the manual.

Code the residence where the student is living for exchange students temporarily living in the U.S.  Code the temporary address if known or the Post Office Box if unknown.  We will add this scenario to the next release of the SEER manual.

Code the Date of First Surgical Procedure as 01/01/2023 in the example provided where the shave biopsy is followed by wide excision. Beginning in 2023, significant changes were made in that shave, punch, and elliptical biopsies are coded as surgical procedure regardless of margin status. Appendix C Skin Surgery Codes state that an incisional biopsy would be a needle or core biopsy of the primary tumor.

Please see Appendix M: Case Studies for Coding Melanoma in STORE v23, Case study 2: Shave Biopsy followed by WLE (page 412), for an explicit example of how to code your example case.

We will clarify this in the upcoming release of the SEER manual,
