20140005 | Primary site--Testis: In the absence of a specific statement that the patient's testicle(s) are descended, should the primary site for a testicular tumor be coded as C621 (Descended Testis) when the mass is palpable on physical exam or demonstrated on scrotal ultrasound? See discussion. | It seems the non-specific Testis, NOS (C629) code is being over used. Many testis cases have no documentation of the patient's testicular descention. However, testicular tumors in adults are frequently detected by palpation or scrotal ultrasound. An undescended testis (a testis absent from the normal scrotal position) would be non-palpable or not amenable to imaging via a scrotal ultrasound. | Unless the testicle is stated to be undescended, it is reasonable to code C621 for primary site. Reserve C629 for cases with minimal or conflicting information. | 2014 |

20140055 | Reportability--Heme & Lymphoid Neoplasms: Is this a reportable case and if so what codes would be used for the primary site and histology?
Lymph node flow cytometry and bone marrow biopsy revealed involvement by a low-grade B-cell lymphoproliferative disorder. Medical oncologist states monoclonal gammopathy, question marginal zone B cell lymphoma versus lymphoplasmacytic lymphoma/lymphoproliferative disorder. |
Based on the information provided, this case is not reportable. Low grade B-cell lymphoproliferative disorder is not reportable, nor is monoclonal gammopathy. There is no definitive diagnosis for marginal zone or lymphoplasmacytic lymphoma. The terminology used includes "question" and "versus" which are not acceptable ambiguous terms for reportability. If possible, follow up with the physician regarding the definitive diagnosis. |

20140072 | Reportability--Head & Neck: Would this be reportable and if so what histology would be coded? Soft tissue mass left cheek excision reveals Carcinoma Ex Pleomorphic Adenoma Non-Invasive with focal vascular invasion. Margins clear. |
Carcinoma ex pleomorphic adenoma (Ca-ex-PA) is reportable. Assign 8941/3. The WHO classification of head and neck tumors defines Ca-ex-PA as an epithelial malignancy arising in a benign pleomorphic adenoma. Most of these originate in the parotid gland but can also arise in other salivary glands. |

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). |

20140006 | Date Therapy Initiated--Corpus Uteri: How should this field be coded for an endometrial primary when the patient undergoes a hysteroscopic polypectomy on 01/08/2014 (Surgery code 25), followed by a TAH/BSO on 02/07/2014 (Surgery code 50)? See discussion. | The hysteroscopic polypectomy showed multiple tissue fragments with invasive endometrioid adenocarcinoma. The hysterectomy and BSO removed an 8.2cm endometrioid carcinoma with no extra-uterine involvement. | Record 01/08/2014 for date therapy initiated assuming there was no therapy prior to this date. A polypectomy is a surgical procedure for purposes of coding date therapy initiated. | 2014 |

20140063 | MP/H Rules--Histology: How is histology coded when a metastatic site is biopsy positive for adenocarcinoma, but the physician clinically states this is cholangiocarcinoma? See discussion. |
The patient underwent a PTA biopsy of a lytic mass showing metastatic adenocarcinoma. Imaging revealed a large hepatic mass consistent with cholangiocarcinoma. The physician's impression on a physical exam note was the PTA biopsy was most consistent with intrahepatic cholangiocarcinoma. However, the PTA pathology report was reviewed at this facility and the final diagnosis was not stated to be cholangiocarcinoma, only adenocarcinoma, NOS.
The priority order for coding histology rules in the MP/H Manual indicates pathology has priority over documentation in the medical record. Following the rules in the MP/H Manual, the histology would be coded as 8140 [Adenocarcinoma, NOS]. While this may be technically correct, it seems that intrahepatic cholangiocarcinoma is often diagnosed as adenocarcinoma on biopsy, but further stated to be cholangiocarcinoma by the physician once other primary sites have been excluded. By applying the rules in the MP/H Manual, cases that seem better characterized as cholangiocarcinomas are being collected as adenocarcinoma, NOS. Should the histology be adenocarcinoma [8140/3] or cholangiocarcinoma [8160/3] for these cases? |
When the physician has reviewed all of the pertinent information, and the physician's opinion is documented stating that the histology is cholangiocarcinoma, code cholangiocarcinoma.
A pathology report from a primary site has the highest priority for coding histology; however, there is no such pathology report in this case. We will review the histology coding instructions and add clarification in the next version. |

20140011 | MP/H Rules/Multiple primaries--Breast: Is the diagnosis of Paget disease two years after a diagnosis of infiltrating duct carcinoma of the same breast a new primary? See discussion. | A patient was diagnosed and treated in 2010 for infiltrating duct carcinoma of the left breast. There was no mention of Paget disease. Then in 2012, the same patient was diagnosed with Paget disease of the nipple of the left breast. Rule M9 seems to apply; so this is the same primary, correct? And the information about the Paget disease is simply never captured, correct? | Yes, Rule M9 makes this a single primary. You could revise the original histology code to 8541/3 on the assumption that Paget was present at the original diagnosis, but not yet identified. | 2014 |

|
20140065 | Summary Stage 2000--Melanoma: How should Summary Stage 2000 be coded for 2014+ diagnosed melanoma cases with satellite nodules or in transit metastases? See discussion. |
The SEER SS (SSS) 2000 Manual indicates satellite nodules (NOS or less than/equal to 2cm from primary tumor) are regional by direct extension (code 2) and in-transit metastasis (satellite nodules greater than 2 cm from primary tumor) are coded as involvement of regional lymph nodes (code 3). However, CSv0205 indicates mapping for satellite nodules/in transit metastasis (coded in CS LN) was changed to Regional, NOS (code 5). There are no definitions listed for code 5 in the SSS 2000 Manual.
Our staff independently code SSS 2000. Should we code the existence of satellite nodules and in transit metastases according to the current definitions in the SSS 2000 Manual or using the mapping information from CSv0205? |
Code the existence of satellite nodules and in transit metastases according to the current definitions in the SSS 2000 Manual. Do not use the mapping information from CS to code SSS. |

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. |

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 |
