What ICD-10 Codes are Used for Bacterial Vaginosis

Bacterial vaginosis (BV) is a vaginal condition resulting from an overgrowth of typical bacteria in the vagina. The ICD-10-CM system has designated codes to classify bacterial vaginosis diagnoses.

Here are some key ICD-10-CM codes for bacterial vaginosis:

N76.0: Acute vaginitis - This can be used when bacterial vaginosis is causing an acute inflammatory response.
A59.0: Trichomoniasis - Trichomoniasis is a specific type of vaginitis caused by a protozoan parasite. Though different from BV, it's sometimes considered in differential diagnoses.
N89.1: Vaginal dysbacteriosis - This is the code for bacterial vaginosis, representing an imbalance in vaginal bacteria.

Which Bacterial Vaginosis ICD Codes are Billable:

N76.0: Yes
A59.0: Yes (though not directly BV, might be relevant in differential diagnoses)
N89.1: Yes

Clinical Information

Bacterial vaginosis is the most common cause of vaginal odor and discharge in reproductive-age women.
It occurs when there's a shift in the vaginal environment, leading to an overgrowth of certain bacteria.
Risk factors include new or multiple sex partners, douching, and lack of a natural protective lactobacilli bacteria.
Many women with BV have no symptoms but can cause a thin white or gray vaginal discharge, burning, itching, and a fish-like odor.
BV can have complications, including increasing susceptibility to other STDs and preterm birth in pregnant women.

Synonyms Include

Gardnerella vaginitis
Non-specific vaginitis
Vaginal bacteriosis
BV
Dysbacteriosis vaginalis

Commonly asked questions

A Bacterial Vaginosis ICD-10-CM code should be utilized in medical documentation when diagnosing or treating a patient for the symptoms or the condition itself.

Bacterial vaginosis is usually treated with prescribed antibiotics, such as metronidazole or clindamycin, taken orally or applied topically to the vagina. It's essential to take the full course of the drug even if symptoms subside.

A diagnosis code for bacterial vaginosis provides a standardized way of indicating that a patient has been diagnosed with or treated for BV. It facilitates clinical care, research initiatives, and administrative tasks, such as billing for healthcare services.
