Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Fluor (vaginalis) due to Trichomonas
- Leukorrhea (vaginalis) due to Trichomonas
Other codes that can never be billed with A59.00
These codes carry an Excludes1 note pointing at A59.00. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading A59.00 alone.
- N89Other noninflammatory disorders of vagina
Risk adjustment
A59.00 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
Medicare coverage
A59.00 is named in 4 Medicare coverage policies — 4 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
