describes the site of origin of the neoplasms and uses the same 3-character and 4-character categories as ICD-10 for malignant neoplasms (C00-C80)
|
topography code
|
|
|
is printed after topographic and morphologic terms that appear elsewhere in ICD-O with an additional modifying word or phrase
|
NOS
|

|
Coding Rules for Topography & Morphology - Rule A. If the diagnosis does not specify the tissue of origin, code the appropriate tissues suggested in the alphabetic index for each ill-defined site in preference to ______
|
NOS
|
|
|
Coding Rules for Topography & Morphology - Rule B. Prefixes: If a topographic site is modified by a prefix such as peri-, para-, or the like, and is not specifically listed in ICD-O-3, code to the appropriate ill-defined subcategory ____ (ill-defined site), unless the type of tumor indicates origin from a particular tissue. This general rule also applies to imprecise phrases such as "area of" or "region of."

Coding Rules for Topography & Morphology - Rule C.Tumors involving more than one topographic category or subcategory: Use subcategory ____ when a single tumor overlaps the boundaries of two or more categories or subcategories and its point of origin cannot be determined. Because more categories have been allotted to neoplasms in ICD-10 than in ICD-9, some previous three-digit categories have been replaced by two three-character categories.

Coding Rules for Topography & Morphology - Rule D. Topography codes for lymphomas: If the site of origin of the lymphoma is in the lymph nodes, code to _____. If a lymphoma involves multiple lymph node regions, code to _____(lymph nodes of multiple regions). Code extranodal lymphomas to the _____, which may not be the site of the biopsy. If no site is indicated for a lymphoma and it is suspected to be extranodal, code to ______(unknown primary site). Lymphomas occur in specific sites, for example stomach, as well as in one or more lymph nodes and therefore are not assigned a site-specific topography code. Lymphomas occurring in specific sites are called extranodal.

Coding Rules for Topography & Morphology - Rule E. Topography code for leukemia: Code all leukemias except myeloid sarcoma (M-9930/3) to ______(bone marrow).

C42.1

Coding Rules for Topography & Morphology - Rule G
Grading or differentiation code: Assign the highest grade or differentiation code described in the diagnostic statement. If a diagnosis indicates two different degrees of grade or differentiation (such as "well and poorly differentiated" or grades II-III"), code to the _______. |
higher grade
|
|
|
Coding Rules for Topography & Morphology - Rule H.Site-associated morphology terms: Use the topography code provided when a topographic site is not stated in the diagnosis. This topography code should be disregarded if the tumor is known to _________. The appropriate site-specific codes are listed in parentheses after morphology terms for neoplasms that usually occur in the same site or tissue
|
arise at another site
|
|
|
Coding Rules for Topography & Morphology - Rule J. Compound morphology diagnoses: Change the ______in a compound term if the term is not listed in ICD-O.
|
order of word roots
|
|
|
Rule K. Coding multiple morphology terms: When no single code includes all diagnostic terms, use the numerically ________number if the diagnosis of a single tumor includes two modifying adjectives with different code numbers. Ex: transistional cell epidermoid carcinoma Transitional cell carcinoma, NOS" is coded M-8120/3 and "epidermoid carcinoma, NOS" is M-8070/3coders should use the numerically higher code number, M-8120/3 in this example, as it is usually more specific.

higher code
