Accession a single primary, diffuse large B-cell lymphoma [9680/3] diagnosed in 2003 per Rule M2. Abstract a single primary when there is a single histology. Per Rule M2, Note 2, a recurrence of the same histology is always a single primary (timing is not relevant).

Code the primary site to C421 [bone marrow] per Rule PH5. Code the primary site to the bone marrow when the peripheral blood is involved, even if no bone marrow biopsy is performed.

According to the notes for Rule PH5, CLL always has peripheral blood involvement (PH5 Note 1). CLL/SLL may also have involvement of lymph node regions in later stages (PH5, Note 2). For this patient a bone marrow biopsy was not performed but he had extensive lymph node and peripheral blood involvement. Therefore, the primary site is coded to C421. In addition, the physician's documentation specifies this patient has Stage 0 disease which indicates this disease process is being classified as leukemia (CLL).

For cases diagnosed 2007 or later, accession a single primary, papillary transitional cell carcinoma of the bladder and ureter [C689, urinary system, NOS] diagnosed in 2010. The steps used to arrive at this decision are:

Open the Multiple Primary and Histology Coding Rules Manual. Choose one of the three formats (i.e., flowchart, matrix or text). Go to the Urinary MP Rules because site specific rules exist for this primary.

Start at the MULTIPLE TUMORS module, rule M3. The rules are intended to be reviewed in consecutive order within a module. This patient has urothelial tumors in two or more of the listed sites (bladder, ureter and renal pelvis) diagnosed within 3 years.

When C689 is assigned because tumors of the bladder and tumors of the ureter were determined to be a single primary and the site of origin is not known (as in this example), rule M8 is applied when a subsequent tumor is diagnosed in one of the listed sites. However, if site C689 [urinary system, NOS] was assigned for other unknown urinary primary site situations, rule M8 would not be used.

Rule M8 was written specifically for urothelial tumors in the renal pelvis, ureter, bladder and urethra. Paraurethral gland [C681] and overlapping lesions of urinary organs [C688] do not belong in rule M8.

We will add this issue to the list of possible revisions for the next edition of the MP/H Rules.

Code the diagnosis date to 3/2011. It wasn't until 3/2011 that the physician documented a reportable diagnosis of essential thrombocytosis [9962/3].

Mild thrombocytosis is not reportable. Therefore, the case was not reportable in 2008. Although the patient was treated in 2010, there was no documentation of a reportable diagnosis.

Assign code 5 [T-cell] for anaplastic large cell lymphoma [9714/3] unless the pathologist specifies that the histology is a B-cell disease process. See Grade rule G2, Note 2.

In the Heme DB, there is a default value in the Grade field for histologies that do not have a grade specified. However, this particular histology does not default to code 9. There was an error in the Grade section of the 2010 and 2012 versions of Heme DB that has now been corrected in the latest release.

For cases diagnosed 1/1/2010 and later, use the Hematopoietic & Lymphoid Neoplasm Manual for instructions on coding aspirin, blood thinners/anti-clotting medications, and transfusions in the field "Other Treatment."

For cases diagnosed 5/1/2002 12/31/2009, use the instructions in the SEER Manual and the instructions in "Abstracting and Coding Guide for the Hematopoietic Diseases" to code aspirin, blood thinners/anti-clotting medications, and transfusions in the field "Other Treatment."

For cases diagnosed 1/1/2001 04/30/2002 use the instructions in the SEER Manual for collection of aspirin, blood thinners/anti-clotting medications, and transfusions in the field "Other Treatment."

Prior to 1/1/2001, these treatment modalities were not collected.

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

Accession a single primary, follicular lymphoma [9690/3] of the breast diagnosed in 2008 per Rule M2.

Accession a single primary when there is a single histology. This is a recurrence of the patient's 2008 follicular lymphoma.

Accession two primaries per Rule M17, neuroendocrine carcinoma [8246/3] of the rectosigmoid junction [C199], and adenocarcinoma in a villous adenoma [8261/3] of the rectosigmoid junction [C199]. There are two tumors with ICD-O-3 histology codes that differ at the third number.

Rule M13 does not apply to neuroendocrine carcinoma. Rule M16 does not apply to this case because there are two specific histologies.

Code the histology as therapy-related acute myeloid leukemia, NOS [9920/3] when the physician states this is a therapy-related AML.

The therapy-related diagnosis may be either clinically or pathologically stated to code the histology to 9920/3. In this case, the physician is aware of the previous chemotherapy, hormone therapy or radiation and adds that knowledge to the histologic findings of AML. The pathology report did not include this clinical, historical information as part of the final diagnosis. However, one can code therapy-related acute myeloid leukemia because clinically it was stated.

We recommend that you clearly document in the abstract that you are coding a clinical histology.

Code the primary site to C068 [overlapping lesion of the mouth] per Rule PH24. Code the primary site to the organ when lymphoma is present only in an organ.

This lesion overlaps the left soft tissue of the maxilla (the maxillary gingiva) [C030] and the left vestibule of the mouth [C061]. There is no documentation indicating in which specific site the lesion arose. The maxilla is the upper jawbone. The soft tissue that overlies the maxilla is a part of the oral cavity. It is reasonable to interpret the documentation such that the tumor in the maxilla is an extension of the overlapping oral mucosa tumor.
