Range Overview
high priority
The ICD-10 code range N80-N98 covers noninflammatory disorders of the female genital tract. This includes conditions such as endometriosis, uterine fibroids, and ovarian cysts. These codes are used to document diagnoses related to the female reproductive system that are not caused by inflammation or infection. They provide a detailed classification system for a wide variety of conditions, allowing for accurate tracking, treatment, and research.
Key Usage Points:
- •Use N80-N98 codes for noninflammatory disorders of the female genital tract.
- •These codes cover conditions such as endometriosis, uterine fibroids, and ovarian cysts.
- •The codes provide a detailed classification system for a variety of conditions.
- •They are essential for accurate tracking, treatment, and research.
- •Always verify the latest ICD-10 updates and changes for these codes.
Coding Guidelines
When to Use:
- ✓When diagnosing endometriosis.
- ✓When diagnosing uterine fibroids.
- ✓When diagnosing ovarian cysts.
- ✓When diagnosing other noninflammatory disorders of the female genital tract.
When NOT to Use:
- ✗When the condition is inflammatory or infectious.
- ✗When the condition is not related to the female genital tract.
- ✗When the condition is related to pregnancy or childbirth.
- ✗When the condition is a malignancy.

- •Relevant family history
Good Documentation Example:
Patient presents with severe pelvic pain. Ultrasound reveals multiple uterine fibroids. Patient has a history of heavy menstrual bleeding.
Poor Documentation Example:
Patient has pelvic pain.
Common Documentation Errors:
- âš Not specifying the location of the condition
- âš Not documenting the severity of the condition
- âš Not including related symptoms
