2025 ICD-10-CM code A59

Trichomoniasis

Use additional codes to identify any other co-existing STIs.

Testing and treatment for trichomoniasis are medically necessary to cure the infection, prevent transmission to others, and reduce the risk of complications (e.g., pelvic inflammatory disease, HIV acquisition).

Clinicians diagnose trichomoniasis based on patient history, physical examination, and laboratory tests. These tests may include a pelvic exam, microscopic examination of vaginal or penile discharge, or nucleic acid amplification tests (NAATs).Treatment involves antibiotics, typically metronidazole or tinidazole, for both the infected person and their sexual partners.

In simple words: Trichomoniasis, also known as "trich," is a very common sexually transmitted infection (STI). It's caused by a tiny parasite and is usually spread through sexual contact. Many people don't have any symptoms, but if they do appear, they can include unusual discharge, itching, and pain in the genital area.It's easily cured with antibiotics, but it's important to get treated to avoid complications and prevent spreading the infection.

Trichomoniasis is a sexually transmitted infection (STI) caused by the parasite Trichomonas vaginalis.It affects the genitourinary tract and can cause a range of symptoms, including abnormal vaginal discharge, genital itching, and painful urination in women. Men often experience no symptoms, but some may have urethral discharge, itching, or burning during urination. While often asymptomatic, trichomoniasis can increase the risk of other STIs, including HIV.

Example 1: A 25-year-old female presents with frothy, yellow-green vaginal discharge, itching, and dysuria. A pelvic exam reveals vaginal erythema. Microscopic examination of the discharge confirms the presence of Trichomonas vaginalis., A 30-year-old male is asymptomatic but his partner was recently diagnosed with trichomoniasis. He is tested and found to be positive for T. vaginalis despite not having any symptoms., A pregnant woman in her second trimester is screened for STIs and tests positive for trichomoniasis.She is treated with metronidazole to minimize the risk of preterm delivery.

Documentation should include signs and symptoms, results of laboratory tests (e.g., wet mount microscopy, NAAT), medication prescribed, and patient education regarding safe sex practices.
