20140003 | Surgery of Primary Site/Surgical Procedure of Other Sites--Endometrium: How are these fields coded for an endometrial primary when the patient undergoes a radical tumor cytoreduction including modified radical hysterectomy, BSO, omentectomy, resection of intra-abdominal and intrapelvic implants, and partial cystectomy? See discussion. | When other regional sites (besides the omentum) are removed with the primary site, how is Surgical Procedure of Other Site coded? There is no cytoreduction surgery code for endometrial primaries, and this patient does not appear to qualify for any of the specific pelvic exenteration codes. Per SINQ 20091118, an omentectomy is not coded in the Surgical Procedure of Other Site field when it is performed with a hysterectomy. |
In general, record surgery of sites/organs not covered in the surgery of primary site codes under surgery of other site. For this case, code the partial cystectomy under surgery of other site. As you point out, the omentectomy is not recorded under surgery of other site when performed with a hysterectomy for an endometrial primary. | 2014 |

20140007 | Surgery of Primary Site--Lung: How is surgery coded when a patient undergoes a mediastinoscopy with mediastinal lymph node sampling and then a later upper lobectomy? See discussion. | The mediastinal nodes were submitted as a separate specimen. The patient also had several peribronchial nodes identified within the lobectomy specimen. Does code 33 (Lobectomy with mediastinal lymph node dissection) require a complete mediastinal lymph node dissection (i.e. the removal of all lymph nodes in mediastinal chain(s) as opposed to a selective sampling/dissection of lymph nodes from multiple mediastinal chains)? |
Assign code 33 in this situation. Code 33 can include mediastinal lymph node sampling. | 2014 |

20140017 | 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. |

20140087 | MP/H Rules/Multiple primaries--Ampulla of vater: Is this a new primary? Patient has intramucosal adenocarcinoma in a tubulovillous adenoma of the ampula of vater in Sept. of 2011. In May of 2012, patient has another ampullary adenoma with intraepithelial carcinoma (pTis) and an area suspicious for invasion. This is coded 8263/3.
Rule M14, Multiple in situ and/or malignant polyps are a single primary, precedes rule M15, An invasive tumor following an in situ tumor more than 60 days after diagnosis is a multiple primary, per the MP rules for 'Other sites', |
Rule M14 applies. Abstract this case as a single primary. |

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. |

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). |

20140009 | Primary site: What primary site do I assign to a Squamous Cell Carcinoma of the parapharyngeal space when there is no other info available regarding a more definitive site within the parapharyngeal space? Each physician involved with the case states the primary site is the parapharyngeal space. This is a patient who was diagosed and treated elswhere and was seen at our hospital several months later for a radical neck dissection for suspected lymph node mets. |
Assign C139 for a primary originating in the parapharyngeal space. This space contains part of the parotid gland, adipose tissue, lymph nodes, nerves, arteries and veins. |

20140022 | 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. |

20140001 | Grade--Brain and CNS: How should grade be coded for a pineal parenchymal tumor of "intermediate differentiation"? See discussion. | Per a web search, the term "pineal parenchymal tumor of intermediate differentiation" refers to a pineal tumor with the histology/behavior that falls somewhere between the category of pineocytoma (9361/1) and pineoblastoma (9362/3). In other words, it is a malignant tumor that is a WHO grade II/III neoplasm because it's histologic features and behavior are not quite equivalent to a pineoblastoma (WHO grade IV). Thus, it appears the expression "intermediate differentiation" is actually referring to a type of WHO classification system rather than the grade field. Should the type of documentation provided in pathology report be used to imply the grade field is being referenced and thus be coded to 2 for "intermediate differentiation" or should grade be coded to 9 based on the information found during the web search? |
Code the grade as 2 based on instruction #8 in the revised grade instructions for 2014.
Do not use WHO grade to code the grade field for CNS tumors. |

20140058 | Reportability--Pancreas: Is a solid pseudopapillary neoplasm of the pancreas reportable? |
Solid pseudopapillary neoplasm of the pancreas is reportable. According to the WHO classification, it is a "low-grade malignant neoplasm…[which] frequently undergoes hemorrhagic-cystic degeneration and occurs predominantly in young women."
Assign topography code C25 with the appropriate 4th digit. Code the histology as 8452/3. |
