MRC135 - ICD10: Diagnostic Coding

Week 3: ICD-10-CM Tables

The Table of Neoplasms is indexed by anatomic site.

Refer to the ICD-10-CM guidelines, Section C.1.2, for more information about how to code neoplasms.

Readings

The following readings will help you learn about the concepts covered this week.

Required Readings

  • Understanding Health Insurance, Chapter 6, “ICD-10-CM Coding,” pp. 170-190.

ICD-10-CM Tables

There are two tables in the ICD-10-CM: the Neoplasm table and the Table of Drugs and Chemicals. Both of these tables contain information to help coders code special cases.


Neoplasm Table

Neoplasms are new growths, or tumors, in which cell reproduction is out of control. For coding purposes, the provider should specify whether the tumor is benign (noncancerous, nonmalignant, noninvasive) or malignant (cancerous, invasive, capable of spreading to other parts of the body).

It is highly advisable that neoplasms be coded directly from the pathology report; however, until the diagnostic statement specifies whether the neoplasm is benign or malignant, coders should code the patient’s sign (e.g., breast lump) or report a subcategory code from the “unspecified nature” column of the documented site using the Index to Diseases Neoplasm table.

The table headings for the Neoplasm table are the following:

  • Primary Malignancy (the original tumor site)
  • Secondary Malignancy (the tumor has spread to a secondary site)
  • Ca in Situ (carcinoma in situ, or the malignant tumor is localized)
  • Benign
  • Uncertain Behavior (it is not possible to predict subsequent morphology or behavior)
  • Unspecified (no further indication of the history or nature of the tumor is reflected in the documented diagnosis)

Table of Drugs and Chemicals
This table identifies drugs or chemicals that caused poisonings and adverse effects.
