Trichomonal vulvovaginitis

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

A vaginal infection caused by a parasite called Trichomonas that affects the vulva and vagina, causing inflammation and discharge. This is a sexually transmitted infection that can cause itching, burning, and discomfort in the genital area.

Coding Tips

  • •Verify documentation specifies trichomonal vulvovaginitis (not just trichomoniasis) to ensure the correct anatomical site is coded
  • •Consider whether sexual partner notification or treatment documentation is present, as this may be relevant for clinical management and follow-up coding
