For cases diagnosed 2007 or later, assign code 8720 [Melanoma, NOS] to melanoma arising in a nevus that does not have a specific code or to melanoma arising in a nevus, NOS.

Currently, ICD-O-3 does not have a specific classification for a melanoma arising in a compound nevus.

Assign C269 for Gastrointestinal tract, NOS. Apply Rule PH24, code to the organ when only an organ is involved. This rule can be used for NOS sites such as GI tract, NOS.

Based on the information provided, this lymphoma is confined to the GI tract -- stomach and small bowel.

Code the histology to SCC 8070/3.

Based on registrar feedback on the NSCLC rule, we added a rule that specifically addresses when ambiguous terminology can be used to code histology other than NSCLC. The lung rules were update 10/12/2018 so please make sure you are using the currently posted rules. The new rule is: Rule H3-Code the specific histology when the diagnosis is non-small cell lung carcinoma (NSCLC) consistent with (or any other ambiguous term) a specific carcinoma (such as adenocarcinoma, squamous cell carcinoma, etc.) when:

* Clinically confirmed by a physician (attending, pathologist, oncologist, pulmonologist, etc.)

* Patient is treated for the histology described by an ambiguous term

* The case is accessioned (added to your database) based on ambiguous terminology and no other histology information is available/documented

Example 1: The pathology diagnosis is NSCLC consistent with adenocarcinoma. The oncology consult says the patient has adenocarcinoma of the right lung. This is clinical confirmation of the diagnosis, code adenocarcinoma.

Your case meets the criteria in bullet 1.

Myelodysplastic syndrome cases with unknown dates of diagnosis identified in pre-2001 casefinding documents should not be accessioned and are not SEER reportable.

For cases identified in 2001 casefinding documents, when the diagnosis date cannot be confirmed using the medical records typically accessed by the registrar or central registry staff, do not accession these cases; they are not SEER reportable. This default applies only to those cases identified in 2001 casefinding documents.

For cases identified in 2002 or later casefinding documents, the attending physician should be contacted and asked to clarify the diagnosis date for cases identified with unknown dates of diagnosis. Clarifying the diagnosis date is necessary to determine whether the case is reportable and whether it should be accessioned.

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

Code the primary site to the sigmoid colon [C187] per Rule PH24. Code the primary site to the organ when lymphoma is present only in an organ. Based on the information provided, the lymphoma is present only in the sigmoid colon.

Code the histology to 9735/3 [plasmablastic lymphoma] and the primary site to C809 [unknown] per Rule PH27.

Code the histology specified when the only histology for the case is preceded by ambiguous terminology. For this case, code the histology to plasmablastic lymphoma because it is the only histology mentioned in the diagnosis.

Per the Heme DB Abstractor Notes section for plasmablastic lymphoma, most patients present with Stage III-IV disease. The positive pleural fluid is likely due to advanced disease. In the absence of any other information for this case, Rule PH27 applies, "Code primary site to unknown primary site C809 when there is no evidence of lymphoma in lymph nodes AND the physician documents in the medical record that he/she suspects that the lymphoma originates in an organ(s) OR multiple organ involvement without any nodal involvement."

For tumors diagnosed prior to 2007:

Report this cases as two primaries, unless there is information in the record confirming one primary.

For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.

Code the behavior as 2 and over-ride the edit. The edit is there to flag unusual combinations. Once you have verified that the behavior is coded correctly, over-ride the edit.

The surgeon stage of T2 is based on size of tumor, the TIS is based on behavior. Code according to pathologically confirmed TIS.
