About coding uterus inversion
The ICD-10-CM code for uterus inversion is N85.5 (Inversion of uterus). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on N85.5.
Within N85 (other noninflammatory disorders of uterus, except cervix), N85.5 is specifically for inversion of uterus. Related codes cover endometrial hyperplasia (N85.0), hypertrophy of uterus (N85.2), subinvolution of uterus (N85.3), malposition of uterus (N85.4), 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.
Don't report N85.5 together with the conditions in its Excludes1 note: current obstetric trauma (O71.2) and postpartum inversion of uterus (O71.2).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
