Report Question ID Question Discussion Answer Year
20051030 CS Eval--All Sites: If any of the CS fields (TS/Extension, LN, or Mets) are based on the TNM and there is no text documenting the basis for the evaluation, are the evaluation fields coded to 0 instead of 1?

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 code 0 [No surgical resection done...based on physical exam...or other non-invasive clinical evidence] to the corresponding eval fields when CS Extension, Lymph Nodes or Mets at Diagnosis are coded based only on the TNM and no further information is available.

20051050 CS Tumor Size--Breast: Is the largest focus or the total area coded for tumor size in a patient presenting with "scattered foci of DCIS, largest focus measuring 0.6cm. DCIS spans a total area of 2.1cm."

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.

Code the size of the largest focus in CS tumor size. Code the tumor size for this case as 006 (6mm or 0.6cm).

20061016 CS Extension--Head & Neck (Larynx): If a patient with cancer of the larynx is described as experiencing hoarseness, is that sufficient information to code "vocal cord fixation" or does that phrase need to be used?

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.

Do not code vocal cord fixation when the only information available is "hoarseness." Vocal cord fixation must be documented on endoscopy. Hoarseness is a common presenting symptom of laryngeal malignancy.

Reportability--Colon: Would a carcinoid tumor, NOS, of the appendix with perineural or angiolymphatic invasion be reportable if there is no mention of malignancy in the pathology report?

Carcinoid, NOS, of the appendix diagnosed in 2015 or later is reportable.

For cases diagnosed prior to 2015

Carcinoids of the appendix are reportable when they meet any of the following conditions.

  • The pathologist designates the carcinoid as malignant

  • Regional lymph nodes are positive for MALIGNANT carcinoid (not reportable if lymph nodes are reported to be involved with benign carcinoid disease)

  • There are discontinuous metastatic implants or involvement

    • Note that the implants/involvement must be designated as malignant. Many benign tumors will spawn implants that are also benign. If implants are benign, this is not a reportable tumor.

    		20010025 Surgery of Primary Site--Prostate: What treatment code is used to represent prostate carcinoma treated with "high intensity focused ultrasound" (HIFU)?

    For cases diagnosed 1998 and later:

    Code the Surgery of Primary Site field to 17 [Other method of local tumor destruction]. HIFU uses focused energy to destroy tissue. It is classified as a surgical procedure.

    		 2001
    		20021022 Histology (Pre-2007): What code is used to represent the histology "non oat cell carcinoma"?

    For tumors diagnosed 2001-2006:

    Code the Histology field to 8046/3 [non-small cell carcinoma] if the pathologist does not provide a more specific histologic type. "Non oat cell" is a synonym for "non-small cell."

    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.

    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.

    		20010119 Scope of Regional Lymph Node Surgery/EOD Fields: When a patient has two simultaneously diagnosed primaries, and a regional lymph node dissection intended for one of the primaries removes nodes that are also regional for the other primary, is the information from the lymph node dissection coded for both primaries?

    For cases diagnosed 1998-2003:

    If the lymph nodes are negative, the status of nodes that are regional for both sites would be used to code the EOD and Site-Specific Surgery fields for both sites.

    If any of the lymph nodes are positive use the histology from the lymph nodes to determine how the EOD and Site-Specific Surgery will be coded. For example: If prostate cancer is an incidental finding when a cystoprostatectomy and pelvic lymph node dissection are done to treat a bladder cancer, and all of the positive lymph nodes reflect the histology of the prostate primary (adenocarcinoma), code the nodes as positive for the prostate primary and negative for the bladder primary.

    		20000508 EOD-Extension--Cervix: Should this field be coded to 11 [minimal microscopic stromal invasion] or 12 [microinvasion] when there is only a statement of "microinvasion" but no measurements describing the level of involvement given?

    For cases diagnosed 1998-2003:

    Code the EOD-Extension field to 12 [microinvasion] when there are no depth of invasion measurements given.

    Code the EOD-Extension field to 11 [minimal microscopic stromal invasion] when there is a statement of "minimal STROMAL invasion."

    Multiple Primaries (Pre-2007)/Primary site/EOD-Extension--Head & Neck: How many primaries are represented by an invasive squamous cell carcinoma of the floor of mouth with in situ squamous cell carcinoma involvement of the frenulum?

    For tumors diagnosed prior to 2007:

    Code the Primary Site field to C04.9 [floor of mouth]. Because the cancer did not INVADE into a neighboring site (through wall, through soft tissue), it just spread along the mucosa (in situ) to involve the frenulum, this is one primary.

    For cases diagnosed 1998-2003, in situ extension via mucosal spread to the frenulum is ignored for purposes of coding EOD-Extension.

    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.
