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 2026, 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.
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.
Pyometra
An accumulation of PUS in the uterine cavity (UTERUS). Pyometra generally indicates the presence of infections.
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.
Uterus
The hollow thick-walled muscular organ in the female PELVIS. It consists of the fundus which is the site of EMBRYO IMPLANTATION and FETAL DEVELOPMENT. Beyond the isthmus at the perineal end of fundus, is CERVIX UTERI (the neck) opening into VAGINA. Beyond the isthmi at the upper abdominal end of fundus, are the FALLOPIAN TUBES.
About the N85 Code Range
ICD-10 code section N85 covers various noninflammatory disorders of the uterus excluding the cervix. These codes are used to classify conditions that alter the uterine structure or function without infection or inflammation.
This section includes specific codes for endometrial hyperplasia (N85.0, including subtypes like benign hyperplasia N85.01 and endometrial intraepithelial neoplasia N85.02), which are associated with abnormal thickening of the uterus lining often linked to abnormal uterine bleeding. Codes such as N85.2 describe hypertrophy of the uterus (enlarged uterus), while N85.3 refers to subinvolution of the uterus, a delayed return to normal size post-delivery. Uterine malposition (N85.4) captures various displacements like retroversion or anteflexion. Other disorders include uterine inversion (N85.5), intrauterine synechiae or Asherman syndrome (N85.6), and hematometra (N85.7), which involves blood accumulation in the uterus. The unspecified code N85.9 is used when a noninflammatory uterine disorder is diagnosed but not specifically described. Understanding these codes helps clinicians and coders accurately document and manage these distinct uterine conditions.
