Coding Tips

  • •This code is specific to trichomonal infection of both the cystitis (bladder) and urethritis (urethra); do not use if only one site is affected
  • •Verify documentation confirms Trichomonas vaginalis as the causative organism and confirm both bladder and urethral involvement before assigning this code
