Reportability--Brain and CNS: Is pseudotumor cerebri reportable?

Pseudotumor cerebri is not reportable. It is not a neoplasm. The pressure inside the skull is increased and the brain is affected in a way that appears to be a tumor, but it is not a tumor.

20031186 Immunotherapy/Radiation Therapy: Is I-131 labeled immunoglobulin coded as immunotherapy or radiation therapy? Code treatment with I-131 labeled immunoglobulin as radiotherapy. The primary action is radiotherapeutic. Radioimmunotherapy (RIT) uses antibodies to deliver the radiotherapy to the site of the tumor. 2003
20051022 Primary Site--Breast: Would a tumor described as located "lower central" be coded to C501 (central) or C508 overlapping (lower)? Code the primary site C501 [Central portion of breast]. Based on the description above, the tumor is located in the central portion of the breast. 2005
20051081 Primary Site--Bladder: What subsite is used for fundus of the bladder?

As of November 2005, Code fundus of bladder to C678 [overlapping lesion of bladder]. Opinions vary regarding the definition of bladder "fundus." However, according to our pathologist consultant, fundus includes posterior, anterior and lateral walls and dome. Fundus does not include the trigone.

A correction to page C-595 of the 2004 SEER manual will be included in the next errata.

20010073 EOD-Extension--Bladder: Both papillary transitional cell ca in situ and sessile (flat) transitional cell ca in situ are diagnosed simultaneously in the bladder. We code the higher histology (8130/2). For extension, do we use the code that corresponds to the histology (01), or to the higher extension code (06)?

For cases diagnosed between 1998-2003:

Code the EOD-Extension field to 06 [sessile (flat) (solid) carcinoma in situ], the higher extension code.

20051024 Primary Site--Corpus uteri: Should a leiomyosarcoma be coded to the site of "uterus" or "myometrium"? Code the primary site of a uterine leiomyosarcoma to C542 [Myometrium]. 2005

Sequence Number--Central/Reportability--Heme & Lymphoid Neoplasms: Is a hematolymphoid disease included in the sequencing if it was not reportable at the time of diagnosis?

Do not include the disease in the sequencing if the original hematolymphoid disease was not reportable at time of diagnosis.

The 2025 SEER Manual Sequence Number--Central Coding Instruction 1.a advises: A ‘reportable’ primary refers to the site/histology/behavior of the tumor and the years when reporting was required. Review of the reportability requirements in effect during the diagnosis year will be needed.

20091068 Primary site--Bladder: What is the appropriate subsite for "adjacent to the bladder neck"? Assign code C679 [Bladder, NOS]. It is not possible to determine the location of the tumor from the description. A tumor that is "adjacent to bladder neck" could be located in the trigone or on the bladder wall (anterior, posterior or lateral). 2009
