EOD-Extension--Lung: For a left upper lobe lung tumor that extends across the fissure into the left lower lobe, should this field be coded to 10 [Tumor confined to one lung] or 77 [Separate tumor nodules in different lobe]?
For cases diagnosed 1998-2003: Assign EOD extension code 10 [Tumor confined to one lung]. EOD extension code 10 applies to a single tumor within one lung, even one that crosses over a fissure into another lobe. EOD extension code 10 is not correct if the tumor extends to the pleura, or if there is atelectasis, obstructive pneumonitis or malignant pleural effusion. Code 77 is incorrect because that is a separate tumor nodule in a different lobe.
Surgery of Primary Site--Skin: What surgery code is used to reflect the amputation of a finger for subungual melanoma?
47 [Wide excision or reexcision of lesion or minor (local) amputation with margins greater than 2cm] is the correct surgery code for amputation of a finger for melanoma.
Histology (Pre-2007)--Colon: Must a case be specifically labeled "familial adenomatous polyposis" or is the mere presence of numerous/multiple polyps sufficient for coding the histology to FAP?
For tumors diagnosed prior to 2007:
The presence of numerous/multiple polyps is not necessarily adenomatous polyposis coli. Adenomatous polyposis is an extreme condition usually characterized by the presence of hundreds of polyps and should be identified as such either clinically or pathologically.
Look for the term "Familial adenomatous polyposis," FAP or one of its synonyms:
Adenomatosis of the colon and rectum [ACR]
Familial adenomatous colon polyposis
Familial colonic polyposis
Multiple familial polyposis
In the absence of these terms, the following probably indicate a diagnosis of FAP:
Hundreds of adenomatous polyps throughout large intestines, and at times, throughout the digestive system
Development of polyps as early as ten years of age, but more commonly at puberty
History of colectomy
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.
Reportability/Histology--Endometrium: Is endometrial hyperplasia with atypia equivalent to atypical hyperplasia of the endometrium (8380/2) and thus reportable?
Endometrial hyperplasia with atypia is equivalent to atypical hyperplasia of the endometrium (8380/2) and thus reportable for cases diagnosed 2021 and later. Our expert pathologist consultant confirmed this for us.
Terminology: Do focus, focal, foci and chips mean the same thing?
Focus, focal, and foci are variations of the same word. Focus (noun) describes an area or point of disease, either grossly or microscopically. Focal (adjective) relates to the area/focus of disease; an example is a prostate with focal adenocarcinoma. This means that the majority of the prostate is benign and the adenocarcinoma is confined to one small area/point. Foci (plural) describe more than one area/focus of disease. A prostate with foci of adenocarcinoma means the disease is multifocal (several areas/points of disease).
Chips are microscopic amounts of either tissue or tumor. A pathologist might examine several chips of prostate tissue, one of which contains a focus of adenocarcinoma.
EOD-Extension--Lymphoma: Would a lymphoma involving mesenteric and retroperitoneal nodes (both site code C77.2) be coded to extension 10 [Involvement of a single lymph node region; Stage I], based on the fact that while more than one "chain" is involved only one "region" is involved?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 20 [Involvement of two or more lymph node regions on the same side of diaphram]. The AJCC lists mesenteric as a core nodal region, but does not list retroperitoneal lymph nodes as a part of this region, so retroperitoneal is a separate region.
The EOD staging scheme for lymphoma uses lymph node REGIONS as the criteria for assigning the extension code. Use the AJCC Cancer Staging Manual as the definitive source for classifying lymph node regions, not the ICD-O-3. If it is a separate LN region per the AJCC, it is coded in the EOD as a separate region.
According to the AJCC curator, the nodal regions are defined in Kaplan's book on Hodgkin disease. Bilateral cervical, or axillary, or hilar, or pelvic, or inguinal nodes count as two regions. Mediastinal and para-aortic lymph nodes count as one region regardless of laterality as they are centrally located. A large mediastinal mass constitutes one region involved regardless of the size.
Update to current manual/Lymphovascular invasion: Are lymphvascular invasion and lymphvascular space invasion on a pathology report the same thing or do they describe different things?
We confirmed with our expert pathologist consultant that lymphovascular invasion and lymphovascular space invasion are synonymous.
First Course Treatment/Neoadjuvant Therapy--Melanoma: How are the three Neoadjuvant Therapy data items (Neoadjuvant Therapy, Neoadjuvant Therapy--Clinical Response, Neoadjuvant Therapy--Treatment Effect) coded when a patient is diagnosed with melanoma in the lymph nodes with no primary skin site identified? The physician gives immunotherapy as neoadjuvant therapy with planned and carried out surgical resection of involved lymph nodes following completion of immunotherapy. There is no "planned definitive surgical resection of the primary site" as no primary site was found,
Assign code 0 to each of the three Neoadjuvant Therapy data items in this situation.
We will add an example to the coding instructions for these data items in the next release of the manual.
Primary site--Heme & Lymphoid Neoplasms: Should the primary site be coded to C779 or C809 when a patient is diagnosed at another facility with mantle cell lymphoma and the staging bone marrow biopsy performed at this facility is negative? There is no available information concerning where the lymphoma originated.
Per PH Rule22, code the primary site to C779 [lymph nodes, NOS].
Rule PH22 is a default rule for lymphomas that is used when there is no other information regarding the primary site and the Heme DB does not indicate a primary site under its Primary Site(s) section. Rule PH27, code the primary site to unknown [C809], does not apply. Only use C809 [unknown] as the primary site when there is no evidence of lymphoma in lymph nodes AND the physician documents that the lymphoma originates in an organ(s).

First course treatment: When a patient has a Haplo bone marrow transplant, is this coded as an allogenic bone marrow transplant since part of his marrow was used in addition to a donor?
Use code 12 in the Hematologic Transplant & Endocrine Procedures data field. Per the NCI, this procedure is an allogeneic transplant.
Rather than wiping out a patient’s immune system before transplanting donor bone marrow, doctors administer just enough chemotherapy to suppress the immune system, which keeps patients from rejecting the donated marrow without harming their organs. The procedure requires just a half-match, meaning that a patient’s parents or children could be suitable donors. AKA: Half-match transplants.
