Code Classification

  • Diseases of the genitourinary system
    (N00–N99)
    • Noninflammatory disorders of female genital tract
      (N80-N98)
      • Other noninflammatory disorders of uterus, except cervix
        (N85)

N85.9 is a billable diagnosis code used to specify a medical diagnosis of noninflammatory disorder of uterus, unspecified. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

This code is applicable to female patients only. It is clinically and virtually impossible to use this code on a non-female patient.

Unspecified diagnosis codes like N85.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Patient Education


Uterine Diseases

The uterus, or womb, is the place where a baby grows when a woman is pregnant. The first sign of a problem with the uterus may be bleeding between periods or after sex. Causes can include hormones, thyroid problems, fibroids, polyps, cancer, infection, or pregnancy.

Treatment depends on the cause. Sometimes birth control pills treat hormonal imbalances. If a thyroid problem is the cause, treating it may also stop the bleeding. If you have cancer or hyperplasia, an overgrowth of normal cells in the uterus, you may need surgery.

With two other uterine problems, tissue that normally lines the uterus grows where it is not supposed to. In endometriosis, it grows outside the uterus. In adenomyosis, it grows in the uterus's outside walls. Pain medicine may help. Other treatments include hormones and surgery.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
