N926 - Irregular menstrual periods with no specific cause identified

International Classification of Diseases

Last updated: 10/3/2025

What is a ICD-10 Code?

ICD-10 (International Classification of Diseases, 10th Revision) codes are used to classify and code all diagnoses, symptoms, and procedures recorded in association with hospital care. These codes provide a standardized way to track health conditions and their treatment outcomes.

Detailed Description

This code indicates that you are experiencing irregular menstrual cycles, meaning your periods may come at unpredictable times, be heavier or lighter than usual, or last for different lengths of time than normal. The 'unspecified' part means that your healthcare provider has documented the irregular bleeding pattern but hasn't identified a specific underlying cause yet. This is often used when initial evaluation is ongoing or when the irregularity doesn't fit into a more specific diagnostic category. Irregular menstruation can have many causes including hormonal changes, stress, weight changes, certain medications, or underlying medical conditions.

Additional Information

The associated abdominal/pelvic ultrasound suggests your doctor is investigating potential structural causes for the irregular bleeding. This is a common diagnostic approach to rule out conditions like fibroids, ovarian cysts, or other pelvic abnormalities that could be contributing to menstrual irregularities.
