Grade--Heme & Lymphoid Neoplasms: Why isn't "T-cell granular lymphocytic leukemia" (9831/3) coded as "5 T-cell" instead of "9" as specified in the Heme database? My path department did not specify any type of grade, but since "T-cell" is part of the name, wouldn't you code it to "5"?

Assign code 5 when the diagnosis on the pathology report specifies "T-cell granular lymphocytic leukemia." The Heme DB grade instruction states "Code grade specified by pathologist. If no grade specified, code 9." In this case, T-cell was specified - code it. The code for T-cell (5) was not automatically assigned in the Heme DB because of the alternate names for this neoplasm. Some of these include NK-cell. Assign code 8 for alternate names with NK.

The alternate names are: Chronic lymphoproliferative disorder of NK cells, Chronic NK-cell lymphocytosis, Chronic NK-large granular lymphocyte (LGL) lymphoproliferative disorder, CLPD-NK, Indolent large granular NK-cell lymphoproliferative disorder, NK-cell lineage granular lymphocyte proliferative disorder, NK-cell LGL lymphocytosis

MP/H Rules/Kidney, renal pelvis--How many primaries are there for this case? Should we stop at rule M8 making this all one primary (C689) even though there were right and left renal pelvis tumors? Rule M3, which contains laterality, does not apply because there is also a bladder tumor. See discussion.

Kidney: originally diagnosed 12/21/2011 with right renal pelvis high grade papillary urothelial cancer. Status post right nephrectomy. Then on 01/10/2013 diagnosed with low grade papillary urothelial cancer of the bladder. 01/21/2013 diagnosed with left renal pelvis urothelial carcinoma iIn situ. Path report stated this may represent a hgh grade papillary urothelial cancer – unable to confirm due to specimen size. On 01/24/2013 left periaortic lymph node biopsy revealed poorly differentiated carcinoma consistent with prior diagnosed right renal pelvis high grade urothelial cancer. Neither the bladder nor the left renal pelvis tumor was compared to the previous right renal pelvis tumor. Also has bone mets.

Abstract this case as a single primary.

First, apply the MP/H rules to compare the 2013 bladder tumor to the 2011 renal pelvis tumor. Rule M8 applies, this is a single primary. Next, apply the MP/H rules to compare the 2013 in situ renal pelvis tumor to the 2011 renal pelvis tumor. Rule M8 applies, this is a single primary. As you correctly pointed out, Rule M3 for bilateral renal pelvis tumors, does not apply because there is also a bladder tumor in this case.

20140021 Reportability--Breast: Is an inflammatory myofibroblastic tumor of the breast with metastasis to the lung reportable? Inflammatory myofibroblastic tumor of the breast with metastasis to the lung is reportable. Metastasis to the lung from the breast tumor indicates that the breast tumor is malignant. All malignant neoplasms are reportable. 2014

Reportability--Breast: Is ADH/DCIS reportable?

Final Dx for left Breast biopsy: Atypical epithelial proliferation (ADH/DCIS). Comment: Sections show small focus of atypical epithelial proliferation with features of atypical duct hyperplasia/low grade duct carcinoma in-situ.

 ADH/DCIS is reportable. DCIS (duct carcinoma in situ) is a reportable neoplasm. When DCIS is stated as the final diagnosis, report the case. 2014

Reportability--Breast: Is this reportable as 8520/2?

Final Diagnosis: Atypical Lobular Hyperplasia (ALH/LCIS). We are seeing this diagnosis quite often.

 ALH/LCIS is reportable. LCIS (lobular carcinoma in situ) is a reportable neoplasm. When LCIS is stated as the final diagnosis, report the case. 2014

Multiple Primaries--Heme & Lymphoid Neoplasms: 2012 path report for removal of an "axillary mass" which consists of 80% diffuse large B-cell lymphoma (DLBCL) and 20% follicular lymphoma. In the original manual, Module 6 instructed us to code as a single primary, DLBCL. However, the multiple primary calculator says each disease is a separate primary. When I looked them up in the data base, I did not get an option to review a current manual. Can you please advise?

Code as a single primary with histology Diffuse Large B-Cell Lymphoma.

In this case, there are two NHLs in the same location at the same time. Apply Rule M4, this is one primary. Per Note 5 under Rule M4, go to Rules PH11and PH15 to assign primary site and histology.

Rule PH11 states to code to the site of the origin (axillary mass) and to diffuse large b-cell lymphoma (9680/3) when DLBCL and any other non-Hodgkin lymphoma (follicular in this case) are present in the same location at the same time.

Using the multiple primaries calculator in this situation will give you two primaries, which is the wrong answer. Use the rules before using the calculator.

To get to the manual, go to the "Help me code for dx year." section. Choose 2010 or later and the most current manual will appear. We recommend that you save a copy of the PDF on your computer.

20140016 MP/H Rules/Histology--Bladder: What is the correct histology code for this situation? See discussion. Patient has 2 bladder tumors, both invasive -- one is transitional cell carcinoma (8120/3) and the other is papillary TCC (8130/3). They have the same extent of disease, both involve the lamina propria. Is this 8120, because of the Note under rule H11 or is this 8130 because under rule H12, it says 'papillary carcinoma and transitional cell carcinoma'? If so, what is the meaning of the note under rule H11?

Rule H12 applies, code to 8130.

The note under H11 is intended to explain the order of the rules; that is, why the rule to code papillary transitional/urothelial cell carcinoma (H12) follows the rule to code transitional/urothelial cell carcinoma (H11).

20140015 Primary site--Heme & Lymphoid Neoplasms: Is there an instruction missing under Rule PH22 of the 2014 Heme Manual that addresses when it might be appropriate to code primary site to C779 for a Stage II lymphoma? See discussion. It appears there is no instruction under PH22 that covers Example 5 (The patient has a history of Stage II lymphoma, no other information is available). All the bulleted instructions are for organ and lymph node combination involvement. Was the 2010 Heme Rule PH31 (Code the primary site to lymph nodes, NOS (C779) when lymph node(s) are involved but no primary site/particular lymph node region is identified) supposed to be listed under PH22? There does appear to be an empty bullet on the current web version.

The 5th bullet under Rule PH 22 was inadvertently omitted. A corrected version of the Heme manual will be posted soon. Thank you for identifying this omission.

In the meantime, please add the following to PH22:

Code the primary site to lymph nodes, NOS (C779) when lymph node(s) are involved but no primary site/particular lymph node region is identified.

20140014 First course treatment/Surgery of Primary Site--Anus: Would infrared coagulation be coded as treatment for AIN III of the anus/anal canal? See discussion. SINQ 20051064 indicates infrared coagulation is not treatment for cancer. Internet search explains that infrared coagulation delivers heat to destroy the tissue so it can be removed. In our region it is currently used to treat internal and external anal low grade squamous intraepithelial lesions (LSIL) and high grade squamous intraepithelial lesions (HSIL). While it is understandable that this wouldn't be coded as treatment for an invasive anal primary, could it be treatment for an in situ tumor? If it is treatment, should it be coded under Surgery code 15 The answer to SINQ 20050164 still applies. Do not code infrared coagulation as cancer treatment. It is used to coagulate blood vessels and not to destroy cancer tissue. 2014
20140013 Primary site--Brain and CNS: How should primary site be coded for a medulloblastoma described as a "posterior fossa mass" and "centered within the fourth ventricle"? See discussion. The associated site code for medulloblastoma in the ICD-O-3 is C716. However, the SEER Manual specifically instructs to ignore the associated site code if a different primary site is noted. Although most medulloblastomas appear to arise in the cerebellum, when described as "centered within the fourth ventricle" can we assume that is the primary site and not simply invasion of the fourth ventricle from the cerebellum?

Code the primary to C717 for this case.

Code the primary site according to the origin of a particular medulloblastoma when it differs from the site code listed in ICD-O-3. The description "centered within the fourth ventricle" suggests that this medulloblastoma originated in the fourth ventricle.
