Surgery of Primary Site/Surgical Procedure of Other Site--Bladder: What codes are used to represent these fields for a deeply invasive bladder primary treated initially with a TURP (for suspected prostate extension that turns out to be pathologically negative) and a TURB that is subsequently treated with a cystoprostatectomy?
For cases diagnosed 1/1/2003 and after, code:
1. Surgery of Primary Site field to 60 [Radical cystectomy (male only)] because the cystoprostatectomy was the most extensive (definitive) surgery performed to the primary site.
2. Surgical Procedure of Other Site to 2 [Non-primary surgical procedure to other regional sites] based on the TURP.
EOD-Extension--Hematopoietic, NOS: If a solitary plasmacytoma originates in the right tonsil and extends to the left tonsil, vallecula and hypopharynx, is extension still coded to 10 [localized disease, solitary plasmacytoma only]?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 10 [localized disease, solitary plasmacytoma only] for all cases of solitary plasmacytoma.
Terminology/EOD-Size of Primary Tumor--Lung: Can the term "opacity" be used to code the size of the primary lung tumor when it is given a size in an imaging study but the "opacity" is not referred to as being suspicious for cancer? See discussion.
Example: How do you code tumor size for a lung primary in which the patient had a CT of the chest that describes a "4 cm opacity in the RUL of the lung." A biopsy of the RUL lung is positive for carcinoma? Would your answer be different if the opacity was described as being "suspicious for carcinoma"?
For cases diagnosed 1998-2003:
Code the EOD-Size of Primary Tumor field to 999 [Not stated] for the example given above. However, if the opacity was described as a "mass" or as "suspicious for cancer," the size could be coded to 040 [4 cm].
Histology (Pre-2007)--Melanoma: What code is used to represent the histology "radial growth phase: melanoma, superficial spreading type; vertical growth phase: epithelioid type"? See discussion.
Can the "growth phase" be used to code histology? If so, would the histology be epithelioid cell melanoma (8771/3)?
For tumors diagnosed prior to 2007:
Code the Histology field to 8771/3 [epithelioid cell melanoma]. The "growth phase" information in this case describes the horizontal spread and the "invasive" or vertical growth through the layers of skin.
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)--Bladder: Is a 1998 transitional cell carcinoma of the bladder, followed by a 2001 squamous cell carcinoma of the bladder reportable as a second primary?
For tumors diagnosed prior to 2007:
Yes. This case is reportable as a second primary. The rule in the SEER Program Code Manual says that invasive bladder cancers with histology codes 8120-8130 [papillary, transitional] are always coded as a recurrence and are an exception to the multiple primary rule. Squamous cell carcinoma [8070] is not a part of that exception.
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.
Terminology/EOD-Extension--Prostate: How does SEER define the prostatic "apex"? See discussion.
Some pathologists define the prostatic apex as including the bottom third of the prostate whereas others regard only the bottom-most portion of the gland to be the apex.
SEER defines the apex as being the bottom-most portion of the gland. Apex means "narrowest part," which in the prostate would be the bottom-most portion of the gland.
EOD-Extension--Lymphoma: How do you code stage and EOD for an extranodal lymphoma with bilateral involvement of a paired site? See discussion.
For example, we frequently see cases of lymphoma occurring in bilateral orbits, or both lungs. This issue was discussed at a 1991 SEER meeting with the tentative answer being that lymphoma involving both organs of a paired site will be coded as stage I (e.g., both eyes or both lungs), as this would be contiguous disease. However, an extranodal lymphoma involving tissue of both limbs (e.g., soft tissue of both arms) will be coded as stage IV because this represents wide areas of involvement that have no connection.
For cases diagnosed 1998-2003:
Bilateral involvement of an extralymphatic paired organ is coded as involvement of a single extralymphatic organ or site for lymphomas. The EOD extension code would be at least 11 (Stage IE). Staging lymphomas of any site depends on whether one or more lymph node regions and/or extralymphatic organs are involved, and whether sites on one or both sides of the diaphragm are involved.
EOD-Extension--Lymphoma: What code is used to represent this field for a lymphoma that involves the spleen and lymph nodes above the diaphragm (e.g., involvement of only the spleen below the diaphragm and cervical lymph nodes above the diaphragm)?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 32 [30 + involvement of the spleen; III S]. The spleen is counted twice (once as the spleen and a second time as a lymph node region below the diaphragm). As a result, the EOD-Extension field is coded to reflect involvement of lymph node regions on both sides of the diaphragm plus involvement of the spleen. See Note 1 on the EOD scheme that states "Any lymphatic structure is to be coded the same as a lymph node region."
Surgical Procedure of Other Site--Pancreas: Should an embolization of liver metastasis for a pancreas primary be coded as treatment?
Code "embolization" (or hepatic artery embolization, HAE) to a metastatic site in Surgical procedure of Other Site. Assign code 1 [nonprimary surgical procedure performed].
This procedure was previously coded as other therapy, experimental. Code as surgery as of July 2005.
