About C57
C57 is the ICD-10-CM diagnosis code for malignant neoplasm of other and unspecified female genital organs. 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 8 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: C57.0 (tube), C57.1 (ligament), C57.2 (ligament), C57.3 (parametrium), C57.4 (unspecified), C57.7 (organs), C57.8 (organs) and C57.9 (unspecified).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
