A59.9

Billable

Trichomoniasis, unspecified

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

What This Code Means

A parasitic infection caused by Trichomonas that affects the urinary and reproductive systems, but the specific location or type of infection is not documented. This is a sexually transmitted infection that can cause discharge, itching, and discomfort.

Coding Tips

  • Use A59.9 only when the documentation does not specify the site of trichomoniasis (such as urethritis, cervicitis, or prostatitis); if a specific site is documented, use the more specific A59.0-A59.8 codes instead
  • Verify whether the patient is male or female and review clinical notes for any mention of specific symptoms or affected anatomical sites, as this may allow for a more specific code assignment
