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.
MP/H/Histology--Lung: What is the histology code for "heterologous biphasic sarcomatoid carcinoma of the lung with prominent rhabdomyoblastic and adenoca differentiation"?
The expert pathologist recommends coding histology to 8980/3 [Carcinosarcoma] for this combination histology.
Expert consultation: The designation "carcinosarcoma" is given when the pathology shows differentiation in both the sarcomatous (rhabdomyoblastic) and carcinomatous (adenoca) elements. This is emphasized in the path for this case with the term "biphasic." The term "heterologous" mean that the sarcomatous component is of a type not normal to lung. Rhabdomyoblastic means skeletal muscle differentiation. Because skeletal muscle is not normally found in lung it is heterologous. If it were smooth muscle, it would be homologous because smooth muscle is found in lung (as a part of the bronchi).
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).

Reportability--Brain: Is angiocentric glioma, WHO grade 1 of the right frontal lobe reportable? If so, how is histology to be coded?
Angiocentric glioma is reportable. The best histology code currently available is 9380/1 [glioma, NOS; uncertain behavior].
According to the WHO Classification of Central Nervous System Tumours, Angiocentric glioma has a behavior of /1. WHO defines it as an epilepsy-associated stable or slowly growing cerebral tumour primarily affecting children and young adults; histopathologicaly characterized by an angiocentric pattern of growth, monomorphous bipolar cells and features of ependymal differentiation.
Primary site--Heme & Lymphoid Neoplasms: Does Rule PH27 apply meaning that primary site is coded to C809 or would it be more appropriate to code to C269 GI Tract NOS since all disease involves the GI tract and this is more specific?
Extranodal lymphoma first diagnosed in the stomach (fundus and antrum) which upon further investigation also involved the small bowel (MALT Lymphoma) in the absence of lymph node findings. MD staged this IIE. Initial thought was Gastric, but PET/CT indicated abnormal uptake involving loop of distended small bowel in the pelvis.
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.
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.
EOD-Extension--Corpus Uteri: How is this field coded for a stage III A endometrial primary with positive pelvic washings, involvement of the omental serosa, and negative lymph nodes?
For cases diagnosed 1998-2003: Code EOD-extension as 85 [Metastasis]. According to our TNM consultant, Omental metastasis is M1, Stage IVB [EOD 85].
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.
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.
Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded when a patient has a lymph node biopsy and peripheral blood that are positive for B-cell chronic lymphocytic leukemia/small lymphocytic lymphoma but refuses a bone marrow biopsy?
Code the primary site to C421 [bone marrow] per Rule PH5. Note 1 for Rule PH5 states CLL always has peripheral blood involvement. If the peripheral blood is positive for CLL/SLL and no bone marrow biopsy is done, code the primary site to C421 [bone marrow].
