Date Therapy Initiated/Reason no treatment--Lymphoma: Is the date of the lymph node biopsy used as the date of treatment if the lymph node biopsy is the first treatment or the only treatment performed? Is the reason for no surgery coded to 0 [Surgery of the primary site was performed]?
For cases diagnosed prior to January 1, 2008, enter the date of the lymph node biopsy (excisional biopsy or biopsy NOS) as the Date Therapy Initiated for a lymphoma when the biopsy is the first or only therapy performed.
Code Reason for No Surgery of Primary Site as 0 [Surgery of the primary site was performed] and the biopsy of a lymph node is coded to 25 in Surgery to Primary Site.
Do not code a fine needle aspiration or core needle biopsy in Surgery of Primary Site.
EOD-Lymph Nodes--Lung: What code is used to represent this field when the only information is a description of:
1. "hilar mass"
2. "mediastinal mass"
3. "enlarged" or "greater than 1 cm" used to describe any of the lymph nodes listed under code 2 in the EOD Lymph Nodes field?
For cases diagnosed 1998-2003:
Code EOD-Lymph Nodes fields as follows for the examples given:
1) 9 [Unknown; not stated] for a "hilar mass"
2) 2 [Mediastinal] for a "mediastinal mass"
3) 2 [Mediastinal] for "enlarged" or "greater than 1 cm," if used to describe any of the named lymph nodes listed under code 2 in the EOD-Lymph Nodes field.
CS Lymph Nodes--Breast: Must there be a statement of "moveable" present to code 25 in this field and if a lymph node is not stated to be "fixed" is it presumed to be moveable? Please provide an example in your answer of when to use code 25.
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
The word "movable" does not have to be used to assign code 25. A "movable" lymph node is an involved lymph node not described as fixed or matted. The general rule is to code the lesser or lower category, which would be the case if neither movability nor fixation is mentioned. See page C-471 of the 2004 SEER Manual.
Code 25 Example: Involved lymph nodes per lymph node dissection. No mention of fixation or matting. Size of largest met within a lymph node is 4mm.
Surgery of Primary Site/Scope Regional LN Surgery--Breast: How should these fields be coded when a sentinel lymph node dissection removes one-to-three axillary lymph nodes and a total/simple mastectomy is done?
Assign code 41 [Total (simple) mastectomy, NOS WITHOUT removal of uninvolved contralateral breast] for Surgery of Primary Site. Assign code 2 [Sentinel lymph node biopsy] for Scope of Regional Lymph Node surgery. Code 41 applies to a total/simple mastectomy with any number of sentinel lymph nodes removed -- as long as all of the nodes removed are designated as sentinel nodes.
Radiation: Is "consolidated" radiation therapy coded as part of first course therapy when there is no documentation of "planned treatment" and the radiation is done 4 months after the initiation of treatment?
Yes, "consolidation" treatment is part of a planned treatment regimen. A treatment regimen may consist of the four following phases:
MP/H Rules/Histology--Bladder: Can information from the CAP checklist that indicates, Tumor configuration: papillary be used to code histology to 8130 [papillary urothelial carcinoma] if the final diagnosis is also stated to be Bladder rumor: urothelial carcinoma and the pathologist stages the case as pTa [noninvasive papillary carcinoma]?
For cases diagnosed 2007 to 2017 ONLY: Code the histology as papillary urothelial carcinoma [8130].NOTE: In the CAP checklist, the statement that the tumor has a papillary configuration is a further description of this tumor. This is supported by the pathologist's stage of pTa [noninvasive papillary carcinoma]. Use the information from the CAP checklist when available. The MP/H Rules will be revised to include the term "configuration" in the specific histology terms for in situ tumors.
The steps used to arrive at this decision are
Step 1: Open the Multiple Primary and Histology Coding Rules manual. Choose one of the three (i.e., flowchart, matrix or text) and go to the Urinary Histo rules. The module you use depends on the behavior and number of tumors identified in the primary site. In this case, the patient has a single bladder tumor per the submitted information.
Step 2: Start at Rule H1 in the Single Tumor module. The rules are intended to be reviewed in consecutive order from Rule H1 to Rule H15. Stop at the first rule that applies to the case you are processing. Stop at Rule H7. Code the histology as 8130/2 (noninvasive papillary urothelial carcinoma) when the urothelial carcinoma is stated to have a papillary configuration.
CS Extension--Lung: How is this field coded for a tumor in the right middle lobe with extension to the bronchus intermedius?
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
Assign CS extension code 20
[Extension from other parts of lung to main stem bronchus, NOS
(EXCLUDES superficial tumor as described in code 11)
Tumor involving main stem bronchus greater than or equal to 2.0 cm from carina (primary in lung or main stem bronchus)].
A right middle lobe tumor that extends to the bronchus intermedius is one that is extending to the main stem bronchus from another part of the lung. The bronchus intermedius is the lower part of the main stem bronchus on the right. It is more than 2.0 cm away from the carina.
Multiple Primaries (Pre-2007): Whenever two hollow organs are diagnosed simultaneously with the same histology, one being invasive and the other in situ, can one assume that mucosal spread has occurred and that this situation represents one primary? In the absence of a physician statement, how do you determine mucosal spread from one organ to another?
For tumors diagnosed prior to 2007:
Yes, this type of situation represents one primary. A tumor that is breaking down can be invasive in the center with in situ cancer at the margins. Occasionally the in situ margin can move into a contiguous organ with the same type of epithelium.
Physicians may describe mucosal spread in various manners. You will see the terms "intramucosal extension," "in situ component extending to," or statements of an invasive component in one organ, with adjacent/associated in situ carcinoma in a contiguous organ with the same type of epithelium. A frequent example of this process is bladder cancer extending into the prostatic urethra via mucosal spread.
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
