20240020 | Histology/Behavior: There are currently no codes available on the ICD-10-CM casefinding list for several of the site-specific intraepithelial neoplasias (8077/2). Will there be an update with additional codes for these sites that currently do not have codes to enable casefinding for these? See the table below.
|
Many of these terms are not specified in the codes and definitions in ICD-10-CM. This is because ICD-10-CM does not have the same granularity as ICD-O-3.2. There are a few sites where intraepithelial neoplasia II and/or III are mentioned. Even though ICD-O-3.2 classifies these as /2 (in-situ), for the intraepithelial neoplasia that are listed in ICD-10-CM, Grade II is designated as benign, while Grade III is designated as in-situ. It is not clear if medical coding will change the Grade II to an in-situ code. All the in-situ codes (except cervix) are included in the casefinding list. Grade III is included with the in-situ codes; however, there is no guarantee that medical coders will code them as in situ. High grades are coded as in-situ in ICD-10-CM. For those where there is no specific intraepithelial neoplasia code, the benign codes will cover any benign lesion for that site. This would make for a lot of review using the codes for casefinding. Most of the benign codes were removed from the casefinding list a couple of years ago to make it more manageable. Use the casefinding list as a guide for these neoplasias. It is not the most definitive source due to the lack of specificity of ICD-10-CM. It is not possible to map every single histology to a specific code. It is also not known how medical coders across the U.S. are coding these neoplasias. For that reason, pathology should remain the foremost casefinding resource used. The casefinding team will need to review the prepared list below and determine what codes to add. Any updates will be incorporated in the FY2025 updates (October 2024.)

20061125 | CS Lymph Nodes: Are positive right superficial inguinal lymph nodes coded to 30 (which is the case for anal canal primaries) or 31 (which is the case for anus primaries) if the primary is stated to be in the "cloacogenic zone" or is an anorectal primary? | This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.Assign code 30 for positive unilateral superficial inguinal lymph nodes for cloacogenic primaries. The cloacogenic zone is part of the anal canal. |

20010007 | Surgery of Primary Site--Skin: For skin primaries diagnosed 1998-2002, what is the difference between code 40 [Wide excision or re-excision of lesion or minor (local) amputation, NOS] and 50 [Radical excision of a lesion, NOS]? | Codes 40 and 50 are not in the scheme for 2003 forward. See history for coding cases diagnosed 1998-2002. | 2001 | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

20150041 | MP/H Rules/Multiple primaries--Breast: Does rule M10 apply in this situation?
L breast biopsy = INVASIVE DUCTAL CARCINOMA
L breast simple mastectomy = 2.0 cm INVASIVE DUCTAL CARCINOMA with an incidental finding of separate 1.0 cm INVASIVE LOBULAR CARCINOMA; pathologist specifically states the tumors are morphologically different. The tumors are both pure Ductal/pure Lobular. |
Yes, Breast rule M10 applies. This case is a single primary.
Follow the MP/H rules even though the "pathologist specifically states the tumors are morphologically different" so that situations like this are reported consistenty accross cancer registries, regions, and states for consistent national reporting. |

20220031 | Tumor Size/Neoadjuvant Treatment: If a patient discontinues neoadjuvant therapy and then has surgery, how is the pathologic tumor size coded with the pathologic tumor size greater than the clinical tumor size? Currently, we are instructed to code 999 for the pathologic tumor size when neoadjuvant therapy is given; what happens when neoadjuvant chemotherapy is discontinued after 3 cycles (plan for 4 cycles)? |
Assign 999 for pathologic tumor size when patient has received neoadjuvant therapy, even when neo-adjuvant therapy is not completed. Describe the details in text fields. |

20200068 | Summary Stage 2018/Extension--Colon: Are colon primaries coded as local or regional (direct extension) on Summary Stage based on invasion into the pericolorectal tissues? For example, is a case with an ascending colon tumor that extends into the pericolorectal tissues, pT3, local or regional by direct extension? |
Code as Localized using the SEER Summary Stage Manual, Colon and Rectum, Note 6. Localized is for subsites that are not peritonealized, including the posterior side of the ascending colon, or when the pathologist does not further describe the "pericolic/perirectal tissues" as either "non-peritonealized pericolic/perirectal tissues" vs "peritonealized pericolic/perirectal tissues" fat and the gross description does not describe the tumor relation to the serosa/peritoneal surface, and it cannot be determined whether the tumor arises in a peritonealized portion of the colon. Refer to the coding instructions in both EOD and Summary Stage for a list of sites that are nonperitonealized or peritonealized. . |

20160047 | Reportability--Eye: Is conjunctival intraepithelial neoplasia (CIN III) from an excision of the left eye conjunctiva reportable? |
Conjuctival intraepithelial neoplasia grade III (CIN III) is reportable. Intraepithelial neoplasia, grade III, is listed in ICD-O-3 as /2. It is reportable for sites other than skin. |

20130019 | Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded when a patient has a lymph node biopsy and peripheral blood that are positive for B-cell chronic lymphocytic leukemia/small lymphocytic lymphoma but refuses a bone marrow biopsy? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the primary site to C421 [bone marrow] per Rule PH5. Note 1 for Rule PH5 states CLL always has peripheral blood involvement. If the peripheral blood is positive for CLL/SLL and no bone marrow biopsy is done, code the primary site to C421 [bone marrow].

20091035 | CS Extension--Ovary: What code is used to capture omental caking? | This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.The term "omental caking" refers to a thickened omentum. In the case of ovarian cancer, omental caking is always indicative of involvement of the omentum. The omentum is an abdominal structure for the purposes of CS extension. Assign the appropriate code between 70-73.
When the size of implants is not stated, but operative report and scans state omental caking, code 71 would be best. When there are no size measurements on the operative report or scan or elsewhere, there is not enough information to assign 72. The choice of code between 70 and 73 will depend on the details of the specific case. |

20081103 | CS Lymph Nodes--Breast: What code should be used for the the following? There is no mention of LNS clinically; the patient has neoadjuvant therapy; and the LNS are matted pathologically. | This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.Use the information from the pathologic evaluation to code CS Lymph nodes. In the nodes evaluation field, assign code 6 [Regional lymph nodes removed for examination with pre-surgical systemic treatment or radiation and lymph node evaluation based on pathologic evidence]. See CS Lymph Nodes note 4. |
