EOD-Extension--Head & Neck: How do you code extension for a supraglottic larynx primary with "pre-epigolottic space" invasion?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 65 [Pre-epiglottic tissues]. Extension to "pre-epiglottic space" is equivalent to extension to "pre-epiglottic tissue."
Primary site--Heme & Lymphoid Neoplasms: What the primary site for a diagnosis of Langerhans cell histiocytosis with multifocal multisystem involvement of the skin, chest, CNS and thyroid, but no evidence of involvement on a bone scan?
Langerhans Cell Histiocytosis (LCH) includes three major groups:
Unifocal: Slowly progressing disease, involves one organ.
Multifocal unisystem: Involves several organs in one system.
Multifocal multisystem: Involves several organs in two or more systems.
When the disease is both multifocal and multisystem, code the primary site to unknown [C809] because there is no way to identify the origin of the neoplasm in this situation.
SEER*Educate provides training on how to use the Heme Manual and DB. If you are unsure how to arrive at the answer in this SINQ question, refer to SEER*Educate to practice coding hematopoietic and lymphoid neoplasms. Review the step-by-step instructions provided for each case scenario to learn how to use the application and manual to arrive at the answer provided. https://educate.fhcrc.org/LandingPage.aspx.
First course treatment--Anus: Is the topical application of trichloroacetic acid to an anal condyloma with AIN III first course treatment coded to 10 [Local tumor destruction, NOS] in the Surgery of Primary Site field?
Code the trichloroacetic acid treatment of reportable AIN III in the "Other Therapy" field. Assign code 1 [Other].
Primary Site/CS Extension--Lymphoma: How should these fields be coded for a malignant lymphoma with spleen involvement, inguinal and iliac adenopathy, T12 lesion with bony destruction, and a paraspinal mass in lower lumbar region with extension into iliac fossa involving left psoas muscle and causing bony destruction?
For cases diagnosed prior to 1/1/2010, 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 primary site C496 [Connective, subcutaneous and other soft tissue of trunk]. When lymphoma is present in an extranodal organ/site and in that organ/site's regional lymph nodes, code the extranodal organ/site as the primary site. In this case, there is a soft tissue paraspinal mass at T12 extending into iliac fossa, left psoas muscle and bone. Lymph nodes are also involved. Assign CS extension code 21 [Direct extension to adjacent organs or tissues].
For cases diagnosed 1/1/10 and later, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.
Surgery of Primary Site--Bladder: Do we code "random bladder biopsies" as an excisional biopsy (27) or as no cancer directed surgery (00) even if the only involvement mentioned on the pathology reports is "focal carcinoma in situ"?
Code the Surgery of Primary Site field to 00 [None; no surgery of primary site] when only random biopsy procedures are performed on the bladder.
Behavior Code--Bladder/Lymphoma: Should the "in situ" designation on a bladder primary's pathology report be ignored that states a diagnosis of "in situ lymphoma"?
Ignore the in situ designation. You cannot assign an in situ behavior code to a lymphoma primary. The term or designation of "in situ" is limited to solid tumors; carcinoma and/or cancer.
Histology (Pre-2007)--Melanoma: How is histology coded if the final diagnosis is "melanoma" and only in the comment section of the pathology report is there an indication of "Type: Lentigo Maligna. Cell Type: Small Cell"?
For tumors diagnosed prior to 2007:
Code the histology as 8742 [lentigo maligna melanoma]. Code the specific histologic type, even if stated only in the comment section.
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.
EOD-Extension--Stomach: What code is used to represent this field for a stomach primary described as linitis plastica?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 30 [Localized, NOS], unless more information is known about the extent of tumor involvement. Coding the Histology field to 8142/3 [Linitis plastica] and the Size of Primary Tumor field to 998 [Diffuse; widespread; 3/4 or more: Linitis plastica] identifies this diagnosis.
In the EOD-Extension field, the depth of invasion is the important characteristic to be coded. The 10 digit EOD corresponds to the AJCC Staging Manual in which the "T" is based on level of invasion. While a diagnosis of linitis plastica indicates a worse prognosis, it does not define the extent of infiltration. There is no luminal mass with linitis plastica. Instead, the entire gastric wall is thickened by tumor.
Multiple primaries--Heme & Lymphoid Neoplasms: Is this 2 primaries? In 2011, a patient had a spinal mass biopsied positive for DLBCL and follicular lymphoma. The heme rules make this one primary coded as DLBCL. Patient had 2 rounds of chemo, but in 2014, he had a recurrent tumor in the same location. The 2014 biopsy was follicular lymphoma. Is this a new primary -- conversion of acute to chronic after treatment? Or is it the same, since FL was diagnosed in the original specimen?
Rule M13 applies, abstract as two primaries. Since both DLBCL and FL were present in 2011, rule M2 does not fit -- not a single histology. Rule M13 reflects the situation in this case much better: an acute neoplasm which was treated and a chronic neoplasm diagnosed later.
MP/H Rules/Histology--Colon: How is histology coded when the final pathology diagnosis is "adenocarcinoma with extensive mucinous features" and the percent of mucinous features is not stated?
Code 8140 using rule H6. Rule H6 applies because the percent of mucinous is not specified.
