About C53

C53 is the ICD-10-CM diagnosis code for malignant neoplasm of cervix uteri. It belongs to block C51-C58 (malignant neoplasms of female genital organs) and chapter 2 (neoplasms). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: C53.0 (endocervix), C53.1 (exocervix), C53.8 (uteri) and C53.9 (unspecified).

Don't report C53 together with the conditions in its Excludes1 note: carcinoma in situ of cervix uteri (D06.-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
