About coding uterus retroversion
The ICD-10-CM code for uterus retroversion is N85.4 (Malposition of uterus). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on N85.4.
Within N85 (other noninflammatory disorders of uterus, except cervix), N85.4 is specifically for malposition of uterus. Related codes cover endometrial hyperplasia (N85.0), hypertrophy of uterus (N85.2), subinvolution of uterus (N85.3), 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.
Don't report N85.4 together with the conditions in its Excludes1 note: malposition of uterus complicating pregnancy, labor or delivery (O34.5-, O65.5).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
