Version 2023
ICD-10:N92.6
Short Description:Irregular menstruation, unspecified
Long Description:Irregular menstruation, unspecified
Status: Valid for Submission
Version:ICD-10-CM 2023
Code Classification:
  • Diseases of the genitourinary system (N00–N99)
    • Noninflammatory disorders of female genital tract (N80-N98)
      • Excessive, frequent and irregular menstruation (N92)

N92.6 is a billable ICD-10 code used to specify a medical diagnosis of irregular menstruation, unspecified. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.

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

The code is commonly used in ob/gyn medical specialties to specify clinical concepts such as excessive, frequent and irregular menstruation.

Unspecified diagnosis codes like N92.6 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.

Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.

Type 1 Excludes

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.

Patient Education


Menstruation

Menstruation, or period, is normal vaginal bleeding that occurs as part of a woman's monthly cycle. Every month, your body prepares for pregnancy. If no pregnancy occurs, the uterus, or womb, sheds its lining. The menstrual blood is partly blood and partly tissue from inside the uterus. It passes out of the body through the vagina.

Periods usually start between age 11 and 14 and continue until menopause at about age 51. They usually last from three to five days. Besides bleeding from the vagina, you may have:

Premenstrual syndrome, or PMS, is a group of symptoms that start before the period. It can include emotional and physical symptoms.

Consult your health care provider if you have big changes in your cycle. They may be signs of other problems that should be treated.
