A59.00 is a billable diagnosis code used to specify a medical diagnosis of urogenital trichomoniasis, unspecified. The code A59.00 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.

The ICD-10-CM code A59.00 might also be used to specify conditions or terms like urogenital infection by trichomonas vaginalis.

Unspecified diagnosis codes like A59.00 are acceptable when clinical information is unknown or not available about a particular condition.

Specific diagnosis codes should not be used if not supported by the patient's medical record.

Information for Patients


Trichomoniasis

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

Most men do not have symptoms. If they do, they may have

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.
