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.
Histology (Pre-2007)--Lung: Should the histology "Polymorphic Adenocarcinoma" be coded to 8022/33 [Polymorphic Carcinoma] or 8140/33 [Adenocarcinoma, NOS]?
For tumors diagnosed prior to 2007:
The histology code for pleomorphic adenocarcinoma of the lung is 8140 [Adenocarcinoma, NOS]. According to our pathologist consultant, "Given lung as primary site I prefer 8140. This loses the pleomorphic modifier, but going to 8022 loses the adeno- designation which is more important. Pathologists occasionally use pleomorphic carcinoma for lung tumors which otherwise dont show any adeno or squamous differentiation, for which 8022 would be appropriate, but in this case we do have the adeno designation."
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.
Multiple Primaries (Pre-2007)--Breast: Synchronous invasive right breast tumors. Ductal carcinoma, NOS in UIQ and Ductal carcinoma, tubular type in LOQ. Are these two primaries or a single primary coded to 8523/3?
For tumors diagnosed prior to 2007:
Code as two primaries, one 8500/3 [Infiltrating duct carcinoma] and one 8211/3 [Tubular carcinoma].
Apply the multiple primary rules first. These are synchronous right breast tumors with different histologies. Therefore, they are separate primaries according to rule 5.a on page 12 of the SEER Program Code Manual. ICD-O-3 histology code 8523/3 is NOT to be used to combine histologies from separate primaries; it is used for mixed histologies in a single primary.
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-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.
Histology/Reportability/Behavior Code--Testis: Is a mature teratoma that is metastatic to lymph nodes reportable? See Description.
Pathology report states, "Histologic sections reveal lymph node metastases, consisting predominantly of mature teratoma. In addition, there are cells scattered through the fibrous stroma which exhibit mild cytologic atypia but have low N:C ratios. The largest metastasis grossly measures 10cm. In addition extracapsular extension is identified. Diagnosis: Lymph Nodes--Metastatic Testicular Carcinoma Involving Multiple Lymph Nodes." The morphology code for mature teratoma is 9080/0. The pathologist does not classify this as an immature teratoma (9080/3). Is this reportable?
Yes, this metastatic teratoma is reportable.
This is a malignant teratoma by virtue of the lymph node metastases. Code the histology as 9080/3 [Teratoma, malignant, NOS]. Primary site is testis [C62_].
EOD-Pathology Extension--Prostate: Is extracapsular extension implied by the phrase, "involvement of periurethral or urethral margins"? See Description.
The prostatectomy final pathology diagnosis states that the tumor involves the periurethral margin. The microscopic describes involvement of the urethral margin.
For cases diagnosed 1998-2003: Code the EOD-Extension field in the 20-34 range, which implies no extension beyond the prostate. Disregard involvement of periurethral margin or urethral margin, NOS, unless the pathologist or surgeon specifically mentions "extraprostatic urethra" involvement.
Reportability--Appendix: Is an appendiceal carcinoid with one periappendiceal lymph node positive for metastatic carcinoid tumor reportable to SEER? See Discussion.
The patient had an appendectomy followed by a hemicolectomy. No residual carcinoid tumor was identified but there was one lymph node positive for metastatic carcinoid tumor.
Yes, this carcinoid is reportable to SEER. This carcinoid is malignant by virture of the lymph node metastasis. Code the behavior as /3.
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.
Primary Site--Melanoma: How would this field be coded for a pleural effusion consistent with metastatic melanoma and "no skin lesions?"
Code primary site as C44.9 [Skin, NOS]. ICD-O-3 does not list a suggested site code for 8720/3 because melanoma can arise in other parts of the body. However, C44.9 [Skin, NOS] is the default when the primary cannot be found.
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.
