A59.00 is a billable ICD-10 code used to specify a medical diagnosis of urogenital trichomoniasis, 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.
Unspecified diagnosis codes like A59.00 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.
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Urogenital infection by Trichomonas vaginalis

Trichomoniasis is a sexually transmitted disease caused by a parasite. It spreads from person to person during sex. Many people do not have any symptoms. If you do get symptoms, they usually happen within 5 to 28 days after being infected.
It can cause vaginitis in women. Symptoms include:
- Yellow-green or gray discharge from the vagina
- Discomfort during sex
- Vaginal odor
- Painful urination
- Itching burning, and soreness of the vagina and vulva
Most men do not have symptoms. If they do, they may have:
- Itching or irritation inside the penis
- Burning after urination or ejaculation
- Discharge from the penis
Trichomoniasis can increase the risk of getting or spreading other sexually transmitted diseases. Pregnant women with trichomoniasis are more likely to give birth too early, and their babies are more likely have a low birth weight.
Lab tests can tell if you have the infection. Treatment is with antibiotics. If you are infected, you and your partner must be treated.
Correct usage of latex condoms greatly reduces, but does not eliminate, the risk of catching or spreading trichomoniasis. If your or your partner is allergic to latex, you can use polyurethane condoms. The most reliable way to avoid infection is to not have anal, vaginal, or oral sex.
