Histology (Pre-2007)--Lung: What code is used to represent the histology "mucin-producing bronchoalveolar carcinoma?" Is mucin-producing synonymous with mucinous?
For tumors diagnosed prior to 2007:
Code histology as 8253 [Bronchiolo-alveolar carcinoma, mucinous]. Mucin-producing bronchoalveolar carcinoma is best classified in ICD-O-3 as Bronchiolo-alveolar carcinoma, mucinous.
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-Clinical Extension--Prostate: Must all three criteria be met (an elevated PSA; documentation that the physical exam was negative; and, if a TRUS was done, there is documentation that the findings were negative) in order to code this field to 15 [Tumor identified by needle by elevated PSA]?
For cases diagnosed 1998-2003:
Refer to the Prostate EOD Coding Guidelines, Final version distributed to SEER Registries 6/20/2001.
Prostate clinical EOD extension code 15 is used when all three criteria are met as listed on page 3 of the Prostate EOD Coding Guidelines. Meeting 1 or 2 of the 3 criteria is not sufficient for code 15. PE must be done and documented as negative. TRUS may or may not be done, but if done, must be documented as negative. PSA must either be elevated or there is no documentation about the PSA.
Codes 20 and 23-24 would be used with positive physical exam or positive TRUS.
Use codes 30-34 when there is no documentation that the physical exam was negative, or no documentation that the TRUS was negative, or when the prostatic apex is involved.
EOD-Extension--Corpus uteri: How should EOD extension be coded when the pathology report shows adenocarcinoma arising in the endometrium with the statement "no invasive carcinoma identified?"
For cases diagnosed 1998-2003: Code endometrial cancer with no invasion to EOD extension code 11 [Confined to endometrium (stroma)]. "No invasion" most likely means no invasion of the myometrium.
Multiple Primaries/Histology--Hematopoietic, NOS/Lymphoma: How many primaries are represented and what are the histologies for "B-cell lymphoma with immunophenotypic findings consistent with hairy cell leukemia" found on a bone marrow biopsy? See Description.
Pathologist completed AJCC lymphoma staging form indicating this case should be abstracted as a lymphoma.
For cases diagnosed prior to 1/1/2010:Abstract as one primary, 9591/3 [B-cell lymphoma, NOS]. The bone marrow diagnosis indicates that the main/definite diagnosis is B-cell lymphoma, with a lesser indication of hairy cell leukemia. Both of these are mature B-cell neoplasms according to the WHO histological classification.
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.
EOD-Size of Primary Tumor: Can the term "filling defect" be used to code tumor size? See Description.
Site: Bladder
CT abd/pelvis: 4 cm filling defect of the bladder encasing jetstream of distal ureter. 2-3 cm lesion may be extension to bladder. KUB: 3-4 cm filling defect within bladder.
Cystoscopy: large bladder tumor with small tumor extending out of the large tumor.
OP Findings: Large tumor on right of bladder extending from bladder neck lateral and posterior
Pathology: TURB: High grade TCC, Grade III with focal lamina propria invasion.
For tumors diagnosed 1998-2003:
Information on size from imaging/radiographic techniques can be used to code size when there is no more specific size information from a pathology or operative report, but it should be taken as low priority, just above a physical exam.
The term "filling defect" from a CT or KUB may be used to code tumor size for bladder in the absence of more reliable size information from path, operative or endoscopic reports.
Surgery of Primary Site/Date Therapy Initiated--Head & Neck: Would a biopsy, NOS, that removed the majority of the tumor be used to code these fields? See Description.
Patient underwent biopsy, NOS, of a carcinoma of the tongue. Subsequent glossectomy revealed microscopic focus of residual squamous cell carcinoma.
If the biopsy NOS removed all macroscopic disease, code the date of the biopsy NOS as the date therapy initiated. If macroscopic disease remained following the biopsy NOS, code the glossectomy date as the date therapy initiated.
EOD-Size of Primary Tumor: Pathologist states that the size of the tumor is difficult to measure but is greater than 3cm but less than 5cm. How would we code the tumor size?
For cases diagnosed 1998-2003:
Code the largest dimension mentioned, since that is the standard rule for coding tumor size. Keep in mind that tumor size is not used in analysis for certain sites such as stomach, colon & rectum, ovary, prostate, and urinary bladder. Tumor size is important for analysis for certain sites such as lung, bone, breast, and kidney.
Grade, Differentiation: Is grade always coded to 4 for a diagnosis of Ewing's sarcoma?
Do not code the ICD-O-3 grade for Ewing sarcoma unless documented in the record.
In the TNM system, grade is required to place Ewing sarcoma into a stage group. For TNM staging purposes, Ewing sarcoma is classified as G4. Do not apply TNM rules to ICD-O coding.
EOD-Size of Primary Tumor--Breast: How would this field be coded, using the revised and expanded breast code, for a lesion described as "1.3 cm infiltrating ductal carcinoma, associated DCIS?"
For cases diagnosed 1998-2003: Code size of primary tumor as 013. The phrasing suggests that the infiltrating ductal carcinoma measures 1.3 cm. DCIS is also present, but no size mentioned.
Multiple Primaries (Pre-2007)--Trachea/Lung: Would synchronous lesions, of the same histology, diagnosed in the right upper lobe of the lung and trachea be a single primary when the physician feels they are two separate primaries?
For tumors diagnosed prior to 2007:
According to SEER rules, abstract as one primary because although these sites have separate topography codes in ICD-O-3, they were coded to the same three-digit topography code in the first edition of ICD-O (SEER Program Code Manual, 3rd Edition, page 8, Exception B). Simultaneous lesions of the same histology in trachea and lung are one primary. Code the primary site to C399 [Ill-defined sites within respiratory system].
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.
