International Classification of Diseases (ICD), Ninth Revision
International Histological Classification of Tumours (IHCT), Second Edition
International Classification of Diseases for Oncology (ICD-O)
International Statistical Classification of Diseases and Related Health Problems (ISCDRHP)

January 1, 2001
December 31, 2000
January 1, 2002
What is perhaps the most important change between ICD-0-2 and ICD-0-3?
Some ICD-O-2 morphology terms have new codes in ICD-O-3
There are new synonyms for existing codes
A small number of disease entities have changed behavior codes
More than 200 terms and synonyms were added to the leukemia and lymphoma section
In ICD-O-3, some terms which are now considered obsolete have been marked as "[obs]". In many cases, obsolete terms which had specific codes in ICD-O-2 have been
Left unchanged in ICD-O-3 so historical data will not be affected
Deleted in ICD-O-3 because they are obsolete
Moved to the "Not Otherwise Specified" category for the disease
Assigned new codes, but the old codes are retained in parentheses
The coding rules in ICD-O-3 have been
Made more user-friendly
All of the above
The matrix principle is the rule that says
The behavior code of a reported diagnosis should never be changed regardless of the terminology used by the pathologist
The behavior codes /0 (benign) and /1 (borderline) are problematic and the matrix in the introduction section of ICD-O-3 should be consulted
The behavior code as reported in the microscopic section of the pathology report takes precedence over that which is stated in the final diagnosis section
The behavior code of a reported diagnosis may be changed so that it truly reflects whatthepathologist describes as the behavior
Which of the following statements is true?
Pathologists use the term "grade" as a synonym for "type" or "category." Registrars, however, recognize the term "grade" as an indicator of cell differentiation.
Although registrars continue to use the term "grade" as an indication of cell differentiation, cell differentiation is no longer an important concept in ICD-O-3.
It is no longer important to recognize when the term "grade" refers to category or when it refers to biologic activity because they are one in the same.
Registrars consider the term "grade" as a synonym for "type" or "category." Pathologists, however, always use the term "grade" as an indicator of cell differentiation.
In 1998, the World Health Organization and the International Society of Urologic Pathologists published a consensus paper describing the preferred terminology for tumors of which of the following anatomic site?
The Uniform Data Standards Committee of the North American Association of Central Cancer Registries has approved two new data fields in response to the implementation of ICD-O-3. The two new fields are:
"histologic type ICD-O-3" and "ICD-O-3 conversion code"
"histologic type ICD-O-2 code" and "ICD-O-3 code"
"histologic type ICD-O-2 code" and "ICD-O-3 conversion code"
"histologic text" and "ICD-O-3 conversion code"
During the conversion from ICD-O-2 to ICD-O-3:
most terms will copy through without review or change
a few terms will change number during the conversion
a few terms that have been split apart will require manual review of supporting text fields or original documents
all of the above
