About coding uterus hypertrophy
The ICD-10-CM code for uterus hypertrophy is N85.2 (Hypertrophy 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 N85.2.
Within N85 (other noninflammatory disorders of uterus, except cervix), N85.2 is specifically for hypertrophy of uterus. Related codes cover endometrial hyperplasia (N85.0), 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.
Don't report N85.2 together with the conditions in its Excludes1 note: puerperal hypertrophy of uterus (O90.89).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
