Report Question ID Question Discussion Answer Year
20031025 Histology (Pre-2007): Is a small cell undifferentiated carcinoma coded to 8041/34 [small cell carcinoma undifferentiated] or to 8045/34 [combination small cell AND undifferentiated carcinoma] using terms from the 2 columns in Appendix 1 of Coding Complex Morphologic Diagnoses? See discussion. Per pathology report, diagnosis is small cell undifferentiated carcinoma in biopsies taken from the laryngeal surface of the epiglottis and left false vocal cord.

For tumors diagnosed prior to 2007:

Code histology as 8041/34 [small cell carcinoma, undifferentiated]. The diagnosis indicates that this is an undifferentiated small cell carcinoma, rather than a mixture of small cell carcinoma with undifferentiated carcinoma.

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.

20031024 Surgical Fields--Head & Neck: How does one code the removal of benign submandibular and sublingual glands performed during a neck dissection for a head and neck cancer? See discussion. Should the removal be coded as incidental in the surgical Procedure if the Other Site field? Does it make a difference if the submandibular gland is removed en toto with lymph nodes or if the gland is submitted as a separate specimen? Does it make a difference if the glands are involved?

Removal of the lower salivary glands is part of a radical neck dissection and is not recorded in Surgery of Primary Site or Surgery of Other Site. Radical neck dissection is coded under "Scope of Regional Lymph Node Surgery."

It does not matter whether or not the gland is submitted as a separate specimen. It does not matter whether or not the gland is involved.

20031023 Grade, Differentiation: Can differentiation be coded from the pathology report for a biopsy from tissue involved by local recurrence? Code grade from original primary site. Do not code grade from a local recurrence. 2003
20031022

Surgery of Primary Site--Head & Neck: Is a composite resection performed for an oral cavity primary coded to 40 [Radical excision of tumor, NOS], 41 [Radical excision of tumor only], 42 [Combination of 41 with resection in continuity with mandibles (marginal, segmental, hemi-, or total resection], 43 [Combination of 41 with resection in continuity with maxilla (partial, subtotal, or total resection)]? See discussion.

Example:

Patient underwent composite resection of left soft palate, tonsillar fossa, medial pterygoid and lateral tongue for a primary of the retromolar trigone. There was no mention of an excision of the mandible; however, the procedure included the application of a mandibular reconstruction plate.

 Use surgery codes 40-43 for composite resection of an oral cavity primary. In the case example, code Site-Specific surgery as 42 [Combination of 41 WITH resection in continuity with mandible]. Even though excision of mandible was not mentioned, there was mention of a mandibular reconstruction plate. Since the retromolar trigone is ON the mandible, resection of the mandible is likely. 2003
20031021 Primary Site--Head & Neck: What is the anatomical distinction among tonsillar fossa, tonsillar pillar, and tonsil NOS? Operative findings describe a right tonsil three times the size of the left tonsil. Tonsil is dissected from the tonsillar fossa. There appeared to be no involvement of tumor below the tonsillar capsule.

The tonsil lies in an indentation called the tonsillar fossa. The tonsillar fossa is bordered on either side by the tonsillar pillars. The tonsillar pillars are part of the supporting structure of the throat opening.

Code C09.9 [Tonsil NOS] as the primary site for the case above.

20031020

Surgery of Primary Site--Head & Neck: Is the removal of the left tonsil during a bilateral tonsillectomy for a right tonsil primary coded in the surgery of the primary site field to 27 [Excisional bx], 30 [Pharyngectomy, NOS], 31 [Limited/partial pharyngectomy; tonsillectomy; bilateral tonsillectomy], or to code 2 under the Surgical Procedure of Other Site field? See discussion.

Our notes document a 1/99 SEER e-mail stating that tonsillectomy/tonsillectomy with wide excision would be code to 31. Is this still correct? Some of our coders felt that code 27 or 30 would be more appropriate.

Is the removal of the contralateral tonsil incidental removal or do we code it under Surgery of Other Regional Site, Distant Site, or Distant Lymph Nodes? If it is coded, would 5 be the correct code?

Assign code 31 [Limited/partial pharyngectomy; tonsillectomy, bilateral tonsillectomy]. Do not code removal of the contralateral tonsil under Surgical Procedure of Other Site. Surgery to remove regional tissue with the primary site during the same procedure is coded in the Surgery of Primary Site field.

20031018 EOD-Extension--Head & Neck (Uvula): Is a stage T2 tumor described on the physical exam as an "ulcerated mass occupying uvula midline soft palate, and extending into the right soft palate. It does not extend into the tonsil area nor into the retromolar trigone" coded to 30 [localized, NOS] or 40 [tumor crosses midline]?

For cases diagnosed 1998-2003:

Code EOD-extension to 30 [localized, NOS]. This is mucosal spread (since there is no muscle in the uvula). Soft palate and uvula are handled as a single site, and extension from uvula to soft palate is not addressed in EOD.

 2003
20031017 Reason for No Surgery of Primary Site: Does code 2 [Contraindicated due to other conditions; autopsy only case] or code 1 [ Cancer-directed surgery not recommended] have priority when coding this field for extensive tumors not surgically treated because of existing comorbidities? See discussion.

Example:

Patient has Stage IVA carcinoma of the tongue. The physician states that patient is not felt to be a good surgical candidate secondary to multiple medical frailties. Patient is treated with beam radiation.

In this case, how do we code Reason for No Site Specific Surgery? Do we use code 2 because surgery was contraindicated due to co-existing medical conditions or do we use code 1 because the tumor is very extensive and surgery would probably not be done anyway?

SEER has not established a priority for assigning the Reason for No Surgery of Primary Site codes. Assign the code which best describes the reason surgery was not performed.

Example: Assign code 2, Contraindicated due to patient risk factors. According to the physician, this is the reason that surgery was not performed.

Surgery of Primary Site--Head & Neck: Will you clarify the use of code 20 [local tumor excision, NOS] versus code 27 [excisional biopsy] when there is no clinical description of a tumor and the pathology report describes more than one specimen from surgery performed on the vocal cords? See discussion.

Specimen A is labeled vocal cord biopsy. Specimen B is labeled left true vocal cord nodule. For specimen B the gross portion of the pathology report describes a .5 cm tissue portion. Is the term "nodule" enough information to code this as an excision? Can we code site specific surgery to code 20 or 27?

Code 20 [local tumor excision, NOS] based on information from the size and description of the specimen.

20031015 EOD-Extension--Lymphoma: How is the following guideline of "any mention of lymph nodes is considered indicative of involvement" applied for EOD-Extension of lymphoma cases when there is a discrepancy between physicians as to the stage at diagnosis? See discussion. A biopsy of mesenteric nodes confirmed lymphoma. A bone marrow biopsy was negative. A CT of the chest indicates "small mediastinal and bilateral hilar nodes, but without convincing adenopathy." The case was Stage 2 per the oncologist and Stage 3 per the surgeon's TNM form.

For tumors diagnosed 1998-2003:

Based on the information provided for this example, the lymphoma involves one site, mesenteric nodes. Code EOD extension as 10 [Involvement of a single lymph node region].

The statement "For lymphomas, any mention of lymph nodes is indicative of involvement" refers to the terms in the paragraph above it on page 8 of the EOD manual: Palpable, enlarged, visible swelling, shotty, lymphadenopathy. While these terms are ignored for other malignancies, they should not be ignored for lymphomas. None of these terms apply to the example provided here. According to the CT, the mediastinal and hilar nodes are "small" "without convincing adenopathy." In other words, the mediastinal and hilar nodes are negative.
