Question:
Solid Tumor Rules (2018)/Histology--Head & Neck: Paraganglioma, NOS is reportable and malignant for cases diagnosed 1/1/2021 and later. Paraganglioma, NOS is listed in the ICD-O-3.2 Coding Table as 8680/3 without synonyms or related terms. Table 4 (ICD-O-3.2 Implementation Guidelines) lists 8693/3 Paraganglioma as a new preferred term. Is this correct? See Discussion.
Discussion:
Table 4 (Changes in reportable terminology), 2021 ICD-O-3.2 Update, does confirm that the term malignant no longer needs to be used to describe a paraganglioma, but Table 4 includes the histology for extra-adrenal paraganglioma, NOS (8693/3) as the new preferred term for paraganglioma. Paraganglioma, NOS is histology code 8680/3. Which code is correct?
This question was prompted from preparing SEER*Educate coding exercises. We will use the answer as a reference in the rationales.
Answer:
The correct code for extra-adrenal paraganglioma is 8693/3. The preferred term for 8380/3 is Paraganglioma, NOS. Table 4 of the 2021 ICD-O update was based on information from WHO.
Table 9 in the Head and Neck ST rules is being revised and formatted differently for ease of coding based on diagnosis year (prior to 2021 and 2021 forward). Not ALL paragangliomas will be included in Table 9. If a term and code are not provided in the rules, refer to ICD-O and updates.
