About the D00–D09 Code Range
In situ growths in this block include carcinoma and melanoma at sites throughout the body. Breast carcinoma in situ arises in the breast without evidence of invasion.
The categories first separate the type of growth and where it occurs. D00 and D01 divide digestive sites by organ. D02 groups the middle ear and respiratory system, with subdivisions for respiratory sites. D03 divides melanoma in situ by body site, while D04 divides skin carcinoma in situ by site.
D05 separates breast carcinoma in situ by type, including lobular and intraductal. D06 distinguishes parts of the cervix, while D07 divides other genital organs by site. D09 includes urinary organs, the eye, endocrine glands, and other or unspecified sites.
