PRINCIPLE VIII. NEOPLASMS
1. Instructions on how to use Chapter 2, Neoplasms (140-239) are provided on page
81, Volume 1 of ICD-9-CM. All neoplasms whether functionally active or not are
classified to Chapter 2. If the neoplasm is functionally active, an additional code should
be used to identify the functional activity.
a. Table of neoplasms.
(1) The Table of Neoplasms gives the code numbers for neoplasms by
anatomical site. For each site, there are six possible code numbers according to
whether the neoplasm in question is malignant, primary, secondary, benign, in situ, of
uncertain behavior, or of unspecified nature.
(2) The description of the neoplasm will often indicate which of the six columns
is appropriate; for example, malignant melanoma of skin, benign fibroadenoma of
breast, or carcinoma in situ of cervix uteri. Where such descriptors are not present, the
remainder of the index should be consulted.
(3) Sites marked with the sign "*"; for example, face NEC*, should be classified
to malignant neoplasm of skin of these sites if the variety of neoplasm is a
squamous-cell carcinoma or an epidermoid carcinoma and to benign neoplasm of skin
of these sites if the variety of neoplasm is a papilloma (any type).
