Histology--Heme & Lymphoid Neoplasms: How is this field coded when the final diagnosis for excisional biopsy of two cervical lymph nodes shows classical Hodgkin lymphoma, histologic subtype cannot be determined, but the COMMENT section of the report indicates there are features of both lymphocyte rich and nodular sclerosis subtypes?
Per Rule PH28, code histology to 9650/3 [Classical Hodgkin lymphoma]. This rule states to code the non-specific (NOS) histology when the diagnosis is one non-specific (NOS) histology and two or more specific histologies.
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. http://seer.cancer.gov/seertools/hemelymph.
Surgery of Primary Site/Immunotherapy--Bladder: Is administration of BCG coded as both surgery and immunotherapy?
Yes, code as both surgery and immunotherapy. The CoC included immunotherapy/BCG under surgery and also under immunotherapy by request of the clinical advisor for bladder, reflecting the mixed-modality nature of the treatments. [Answer from CoC I & R]
First-Course of Cancer-Directed Therapy Fields/Hematopoietic, NOS: How do you code treatment for a myelodysplastic syndrome when a patient is admitted to receive a "second transfusion 7 months after diagnosis"?
The first course of treatment for these hematopoietic primaries lasts until there is a treatment change. For the case you cite the second transfusion (7 months after diagnosis) would be first course treatment. Code the Other Cancer-Directed Therapy Field to 1 [Other cancer-directed therapy].
First Course Treatment--All Sites: The patient has undergone part of the planned first course of treatment when a metastatic deposit is identified. If the patient continues with the planned first course of treatment, should the modalities of treatment given after the metastatic deposit is discovered be included in the coding of the first course of cancer-directed treatment fields?
Yes, those modalities should be counted as part of first course of cancer-directed treatment if the patient continues with the planned first course. For example, if patient has the originally planned type of surgery, radiation, or drug protocol, then code the given treatment as first course.
Caution: It is not a change in the treatment plan if the drugs are changed but the action of the drugs remains the same. This is still first course. However, if the treatment is changed from a chemotherapy drug to a hormonal drug following the discovery of the mets, do not code the hormonal therapy as first course.
Reportability/Ambiguous Terminology--Esophagus: Is a case with a biopsy diagnosis of "... focal areas suspicious for adenocarcinoma in situ change" reportable if the diagnosis on the partial esophagectomy specimen only includes the phrase "... with foci of high grade dysplasia; no invasive carcinoma identified"?
The case is not reportable.
The biopsy with a suspicious result (suspicious for adenocarcinoma) was disproven by the esophagectomy.
Histology--Vulva: How is the histology coded for vulvar intraepithelial neoplasia III (VIN III)/Squamous cell carcinoma in situ from a pathology report of the vulva, 8070/2 for squamous cell carcinoma in situ or 8077/2 for VIN III? The rules do not discuss this particular situation.
Assign 8077/2 for high-grade squamous intraepithelial lesion, VIN 3 in this case. The WHO Classification of Female Genital Tumors, 5th edition, states that squamous intraepithelial lesions (SILs) of the vulva are also known as vulvar intraepithelial neoplasia, HPV-associated. The term squamous cell carcinoma in situ is not recommended.
Reportability/Histology--Skin: Is dermatofibrosarcoma protuberans (DFSP) with fibrosarcomatous overgrowth, DFSP with fibrosarcomatous component Grade 2, or DFSP with focal myxoid features (2022) reportable for 2021-2022 diagnoses?
Yes. DFSP with fibrosarcomatous overgrowth and DFSP with fibrosarcomatous component Grade 2 are synonymous with fibrosarcomatous DFSP (8832/3). Our expert pathologist also advises that DFSP with focal myxoid features is the same as DFSP, myxoid (8832/3).
Reportability/Histology--Gallbladder: Is Intracholecystic papillary neoplasm (ICPN) with low-grade intraepithelial neoplasia reportable? The primary site is gallbladder.
Intracholecystic papillary neoplasm (ICPN) with low-grade intraepithelial neoplasia is not reportable. The WHO assigns a behavior of 0 to these neoplasms.
First Course Therapy/Surgery of Primary Site--Prostate: What is the correct surgical code for irreversible electroporation ablation of the prostate diagnosed in 2021?
Assign code 17 for irreversible electroporation ablation of the prostate when there is no tissue submitted to pathology for a 2021 or 2022 case.
Multiple Primaries/Histology--Mycosis Fungoides/Cutaneous T cell Lymphoma: Physicians often use the terms cutaneous T cell lymphoma (CTCL) and mycosis fungoides interchangeably and yet the SEER Single versus Subsequent Primaries of Lymphatic and Hematopoietic Diseases table indicates that these 2 diagnoses represent separate primaries. Do these cases represent one primary? If so, what histologic type should they be coded to?
For cases diagnosed prior to 1/1/2010:The patient does not have two different malignancies. Code the Histology field to 9700/3 [mycosis fungoides], the specific type of cutaneous T cell lymphoma. Mycosis fungoides is one of several types of cutaneous T cell lymphoma. Physicians often refer to mycosis fungoides by the "umbrella term" cutaneous T cell lymphoma.
The table indicates that the broad category of "T/NK-cell NHL" (which includes CTCL) and mycosis fungoides are presumably separate primaries because several entities are included in that broad category. In the specific case cited above, one entity (CTCL) within the broad category (T/NK-cell NHL) and mycosis fungoides are not separate primaries.
For cases diagnosed 2010 forward, 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.
