The most apparent change in neoplasm coding for ICD-10-CM is the number of codes due to increased specificity, one of the major advantages to the new system. In addition to laterality (left, right, bilateral, and unspecified), ICD-10-CM includes more specific codes for reporting the sites of neoplasms.

ICD-9-CM contains codes for breast cancer in the categories 174 and 175 broken down by gender and site. Category 174 (malignant neoplasm of female breast) contains nine codes. Category 175 ­(malignant neoplasm of male breast) contains two codes.

In ICD-10-CM, the codes for breast cancer are located in category C50 (malignant neoplasm of breast). Those codes are broken down by gender, laterality, and site. ICD-10-CM has 54 codes compared to 11 in ICD-9-CM. For every code for female breast cancer, ICD-10-CM includes a comparable code for male breast cancer.

This tip is adapted from “ICD-10 neoplasm codes: New look, similar steps” in the November issue of Briefings on APCs.
