C57.0Malignant neoplasm of fallopian tube

C57.0 is the ICD-10-CM diagnosis code for malignant neoplasm of fallopian tube. It belongs to category C57 (malignant neoplasm of other and unspecified female genital organs), 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 3 subcodes must be used instead.

Within C57 (malignant neoplasm of other and unspecified female genital organs), C57.0 is specifically for malignant neoplasm of fallopian tube. Related codes cover broad ligament (C57.1), round ligament (C57.2), parametrium (C57.3), uterine adnexa, unspecified (C57.4), other specified female genital organs (C57.7), overlapping sites of female genital organs (C57.8) and female genital organ, unspecified (C57.9).

To report this condition, pick the subcode that matches the documentation: C57.00 (tube), C57.01 (tube) and C57.02 (tube).

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