Assign code 40, Pull through WITH sphincter preservation (colo-anal anastomosis).  The National Cancer Institute Dictionary of Cancer Terms defines coloanal anastomosis as a surgical procedure in which the colon is attached to the anus after the rectum has been removed. It is also called coloanal pull-through.

Abstract a single primary when there are multiple tumors of carcinoma NST/duct and lobular using the current Breast Solid Tumor Rules, Rule M10, May 2023 Update, for cases diagnosed 01/01/2018 and forward in the examples provided.  The rule also notes to follow the H rules to determine the correct histology code when a mixture of behaviors is present in carcinoma, NST and lobular carcinoma. Rule M5 does not apply as the timeframe is less than 5 years in both examples.

The 2023 update for the Breast Solid Tumor Rules (released November 2022) states: The rules for determining single versus multiple primaries in tumors with carcinoma NST/duct and lobular carcinoma have been revised and now align with ICD-O-3.2.  Applicable Histology Rules have also been revised to reflect ICD-O-3.2 histology terminology and corresponding ICD-O codes.

Code Lupron as second course therapy and code active surveillance as first course therapy in this scenario. The 2023 SEER Manual states to code all treatment data items to 0 or 00 (Not done) when the physician opts for active surveillance, deferred therapy, expectant management, or watchful waiting.  Assign code 2 to Treatment Status. 

Active surveillance is not the same as "refusing treatment."  Active surveillance is a valid option offered to the patient.  The patient chose this option and later changed their mind.  This is not a refusal of recommended treatment.

Document all the details in the appropriate treatment text fields.

Code AML with monocytic differentiation as acute myeloid leukemia, NOS (9861/3) per consultation with our expert hematopathologist.

Acute monoblastic and monocytic leukemia (9891/3) and acute myelomonocytic leukemia (9867/3) are distinct entities according to the WHO. "AML with monocytic differentiation" is a descriptive diagnosis, whereas, "Acute monoblastic and monocytic leukemia" are specific diagnoses. In the WHO Classification of Tumours, Central nervous system tumours (4th Ed) in 2016, WHO began integrating information on molecular alterations that provide significant prognostic implications and/or a therapeutic target into the histology code/term itself. As a result it is also important to look at the molecular testing because acute myeloid leukemias can have different molecular mutations that could result in coding to a different histology code. In this case, there was no other information regarding additional immunophenotyping, so that is why AML, NOS was assigned.  Acute myeloid leukemia with monocytic differentiation has been added to the Hematopoietic and Lymphoid Neoplasm Database as an alternate name for 9861/3.

Abstract a single primary and assign code 9700/3 for MF.  According to our subject matter expert, this is all MF.  When MF progresses, there can be large cd30 positive T cells. This is not the same as anaplastic large cell lymphoma.

Report intracholecystic papillary neoplasm (ICPN) with high-grade dysplasia (8503/2) of the gallbladder.

Do not report superficial angiomyxoma (8841/0) or aggressive angiomyxoma (8841/0).  WHO Classification of Female Genital Tumors, 5th edition, defines deep (aggressive) angiomyoma as a benign, infiltrative, myxoid spindle cell neoplasm that occurs in deep soft tissue of the pelviperineal region.

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+.

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,

Assign code 9702/3 for  EBV+ nodal T- and NK-cell lymphoma. Primary nodal EBV-positive T- or NK-cell lymphoma is a rare lymphoma type introduced in the 2017 WHO Classification of Tumours of Haematopoietic and Lymphoid Tissues (4th Ed.) as a variant of peripheral T-cell lymphoma (PTCL). It  presents more commonly in elderly and/or immunodeficient patients, lacks nasal involvement, and is more often of T-cell rather than NK-cell lineage.
