About N85.0
N85.0 is the ICD-10-CM diagnosis code for endometrial hyperplasia. It belongs to category N85 (other noninflammatory disorders of uterus, except cervix), block N80-N98 (noninflammatory disorders of female genital tract) and chapter 14 (diseases of the genitourinary system). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.
Within N85 (other noninflammatory disorders of uterus, except cervix), N85.0 is specifically for endometrial hyperplasia. Related codes cover hypertrophy of uterus (N85.2), subinvolution of uterus (N85.3), malposition of uterus (N85.4), inversion of uterus (N85.5), intrauterine synechiae (N85.6), Hematometra (N85.7), other specified noninflammatory disorders of uterus (N85.8), noninflammatory disorder of uterus, unspecified (N85.9) and 1 more.
To report this condition, pick the subcode that matches the documentation: N85.00 (unspecified), N85.01 (hyperplasia) and N85.02 ([EIN]).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
