Term
Chapter 2 of the ICD-10-CM contains the codes for most __ and all __ neoplasms. Certain benign neoplasms, such as __, may be found in the specific __ chapters. To properly code a neoplasm it is necessary to determine from the record if the neoplasm is __, __, __, or of __ histologic behavior. If malignant, any secondary (__) sites should also be determined.

-benign
-malignant
-prostatic adenomas
-body system
-benign
-in-situ
-malignant
-uncertain
-metastatic
Term
A _ malignant neoplasm that _ two or more _ (next to each other) sites should be classified to the subcategory/code .8 ('_'), unless the combination is specifically _ elsewhere. For multiple neoplasms of the _ that are not contiguous such as tumors in different _ of the same _, codes for _ should be assigned.
Definition
-primary
-overlaps
-contiguous
-overlapping lesion
-indexed
-same site
-quadrants

Term
Malignant neoplasms of _ tissue are to be coded to the site of _ mentioned, e.g., _ pancreatic malignant neoplasms involving the stomach are coded to _, unspecified (C25.9).
Definition
-ectopic
-origin
-ectopic
-pancreas
Term
The _ table in the Alphabetic Index should be referenced _. However, if the histological term is documented, that _ should be referenced first, rather than going immediately to the _, in order to determine which _ in the Neoplasm Table is appropriate. For example, if the documentation indicates “_,” refer to the term in the Alphabetic Index to review the entries under this term and the instructional note to “_ neoplasm, by site, benign.” The table provides the proper code based on the _ of neoplasm and the _. It is important to select the proper _ in the table that corresponds to the _ of neoplasm. The Tabular List should then be referenced to verify that the _ has been selected from the table and that a _ site code does not exist.

Term
The only exception to this guideline is if a patient admission/encounter is _ for the administration of _, _ or _ therapy, assign the appropriate Z51.-- code as the first-listed or _ diagnosis, and the diagnosis or problem for which the _ is being performed as a _ diagnosis.

Term
When a patient is admitted because of a primary neoplasm with _ and treatment is directed toward the _ site only, the secondary neoplasm is designated as the _ diagnosis even though the _ malignancy is still _.

Term
When admission/encounter is for management of an _ associated with the _, and the treatment is only for _, the appropriate code for the _ is sequenced as the principal or first-listed diagnosis followed by the appropriate code for the _ (such as code D63.0, _ in neoplastic disease).

To be used only when a diagnosis can not be clearly identified in the record.
Term
