Other noninflammatory disorders of uterus, except cervix (N85) ICD-10-CM
The N85 code range covers other noninflammatory disorders of uterus, except cervix with 14 ICD-10-CM diagnosis codes. 12 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the N85 range.
Asherman Syndrome
A condition with obliterated endometrial cavity causing secondary AMENORRHEA.
Atypical Endometrial Hyperplasia
A neoplastic clonal expansion of endometrial glands characterized by cytologic changes of the epithelium and the presence of an increased number of endometrial glands. The glands form crowded aggregates with tubular or branching patterns which are cytologically distinct from the background architectural and cytological pattern. It is associated with molecular changes seen in endometrioid endometrial carcinoma, including microsatellite instability, PAX2 inactivation, and PTEN, KRAS, and CTNNB1 gene mutations.
Endometrial Hyperplasia
Benign proliferation of the ENDOMETRIUM in the UTERUS. Endometrial hyperplasia is classified by its cytology and glandular tissue. There are simple, complex (adenomatous without atypia), and atypical hyperplasia representing also the ascending risk of becoming malignant.
Hematometra
Blood-filled UTERUS.
Malposition of Uterus
Orientation of the uterus in an unusual anatomic location or position.
Uterine Inversion
A complication of OBSTETRIC LABOR in which the corpus of the UTERUS is forced completely or partially through the UTERINE CERVIX. This can occur during the late stages of labor and is associated with IMMEDIATE POSTPARTUM HEMORRHAGE.
About the N85 Code Range
These disorders affect the uterus, but not the cervix, and are described as noninflammatory rather than inflammatory.
N85.0 groups endometrial hyperplasia, an overgrowth of the uterine lining. Its subdivisions distinguish unspecified hyperplasia, benign hyperplasia, and endometrial intraepithelial neoplasia. Other subdivisions name changes in uterine size or position, tissue bands inside the uterus, and blood collecting there. Separate codes identify isthmocele, another specified disorder, or an unspecified disorder.
