Code alcohol ablation under Surgery of Primary Site 2023. Code alcohol embolization as Other Therapy when tumor embolization is performed using alcohol as the embolizing agent.

Alcohol ablation, also known as an ultrasound-guided percutaneous ethanol injection (PEI); is treatment that involves injecting concentrated alcohol directly into the tumor. Embolization uses special techniques to close off blood flow by introducing special medications or using other techniques designed to block blood vessels. Types of embolization are arterial embolization as with alcohol (ethanol), chemoembolization, and radioembolization. Refer to the current SEER Program Coding and Staging Manual when assigning surgery and embolization procedures.

1) Do not infer the percent of viable tumor if only percent of necrosis is provided. For the example, assign code 6 when Neoadjuvant therapy was completed and the treatment effect in the breast is stated only as “Present".

2) Do not use the residual cancer burden (RCB) score from the pathology report to code the Neoadjuvant Therapy--Treatment Effect field for breast cancer. We do not have a crosswalk from RCB to neoadjuvant Therapy--Treatment Effect.

RCB index is an accurate and reliable tool to assess patient prognosis. RCB is estimated from routine pathologic sections of the primary breast tumor site and the regional lymph nodes after the completion of neoadjuvant therapy. The data item Neoadjuvant Therapy--Treatment Effect records information on the primary tumor only.

NTRK-rearranged spindle cell neoplasm is a newly identified variant of sarcoma; however, WHO has not yet proposed a specific ICD-O code for this rare neoplasm. Code to spindle cell sarcoma (8801/3).

WHO defines NTRK-rearranged spindle cell neoplasm as an emerging group of molecularly defined rare soft tissue tumors that span a wide group of morphologies and histological grades, and are most often characterized by a spindle cell phenotype among other characteristics.

Solid pseudopapillary neoplasm of the pancreas is reportable for cases diagnosed in 2014 and later. Report solid pseudopapillary neoplasm of the pancreas (8452/3) as the guidance in SINQ 20140058 is still in effect.

The 4th and 5th editions of the WHO Classification of Tumors of the digestive system define solid pseudopapillary neoplasm of the pancreas as a low-grade malignant pancreatic tumor.

The patient's previous acinar adenocarcinoma in the right lower lobe of the lung in 2020 and squamous cell carcinoma in the right middle lobe of the lung in 2021 were correctly abstracted as two primaries per rule M8 as they are in different rows in Table 3. The NSCLC, RUL (8046) diagnosed in 2022 would not be abstracted as a third primary because NSCLC is a broad category which includes all histologies in Table 3 (except for small cell carcinoma/neuroendocrine tumors (NET Tumors) 8041 and all subtypes), and because it was diagnosed less than 3 years after the 2021 squamous cell carcinoma, RML (8070).

Assign 9380/1 for low grade glioma diagnosed 1/1/2018 forward and for low grade glioma diagnosed prior to 1/1/2018 assign code 8000/1 on the advice of our expert neuropathologists. The site/type combination of C71 _ and 9380/1 will flag histology/site/behavior edits which should be overridden.

Low grade glioma is an umbrella term or non-specific diagnosis, primarily seen on radiologic reports such as CT scans and MRIs. Often, the patient is actively followed with scans and surgical intervention delayed or not recommended. WHO Classification of Central Nervous System Tumors, 5th edition, does not recognize this term and indicates that tissue diagnosis (including genetic testing) is needed to provide a specific diagnosis. Since biopsy of these “neoplasms” is not routinely done, a definitive diagnosis is not available. Literature searches yielded conflicting information with some stating low grade gliomas are malignant with an indolent clinical course while others felt they were benign. Until such time as WHO proposes a code for this neoplasm, our expert neuropathologists recommend coding glioma, NOS with borderline behavior 9380/1. 

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.

High grade squamous dysplasia of the tongue is reportable as of 2021 and later as 8077/2.

Use the ambiguous terminology list as a guide in the absence of additional information after reviewing all available information and consulting the physician who diagnosed and/or staged the tumor. 

Equivalent to "Diagnostic for" malignancy or reportable diagnosis

• most certainly carcinoma
• malignant until proven otherwise

Not Equivalent to "Diagnostic for" malignancy or reportable diagnosis

• almost certainly ("almost" conveys uncertainty in comparison to "most" as in "most certainly")

We will update SINQ 20180104.

Do not report serous borderline tumor–micropapillary variant of the ovary (8460/2, C569) as borderline ovarian tumors are not reportable. This applies to cases 2018 and later.

Do report serous borderline tumor–micropapillary variant of the testis as stated in SINQ 20220032. It is reportable for cases diagnosed Jan 1, 2021 and later.
