| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| A59.01 | Trichomonal vulvovaginitis | Use when documentation specifies vulvovaginitis caused by Trichomonas vaginalis. |
|
| A59.02 | Trichomonal prostatitis | Use when documentation specifies prostatitis caused by Trichomonas vaginalis. |
|
| A59.03 | Trichomonal cystitis and urethritis | Use when documentation specifies cystitis or urethritis caused by Trichomonas vaginalis. |
|
| A59.9 | Trichomoniasis, unspecified | Use when documentation does not specify the site of trichomoniasis infection. |

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Primary ICD-10-CM Codes for trichomoniasis
Decision Criteria
clinical Criteria
- Presence of frothy discharge and positive NAAT for T. vaginalis
Clinical Validation Requirements
- Frothy yellow vaginal discharge
- pH >4.5
- Motile trichomonads on wet mount
Code-Specific Risks
- Misclassification if site is not specified
Coding Notes
- Ensure documentation specifies the site of infection to avoid using unspecified codes.
A59.02 - Trichomonal prostatitis
Use when documentation specifies prostatitis caused by Trichomonas vaginalis.
Clinical Validation Requirements
- Prostatic tenderness
- Trichomonas vaginalis detected in urine PCR
Coding Notes
Ensure documentation specifies the site of infection to avoid using unspecified codes.
A59.03 - Trichomonal cystitis and urethritis
Use when documentation specifies cystitis or urethritis caused by Trichomonas vaginalis.
Clinical Validation Requirements
- Dysuria
- T. vaginalis confirmed via NAAT in first-void urine
Coding Notes
Ensure documentation specifies the site of infection to avoid using unspecified codes.
A59.9 - Trichomoniasis, unspecified
Use when documentation does not specify the site of trichomoniasis infection.
Clinical Validation Requirements
- Positive test for Trichomonas vaginalis without site specification
Coding Notes
Encourage providers to specify the site of infection to avoid using unspecified codes.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Other specified bacterial agents as the cause of diseases classified elsewhere
B96.89Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Trichomoniasis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code A59.01.
Impact
Clinical: May lead to inappropriate treatment, Regulatory: Increased risk of audits, Financial: Potential loss of reimbursement
Mitigation Strategy
Educate providers on the importance of site-specific documentation, Implement documentation templates
Impact
Reimbursement: Potential for lower reimbursement due to unspecified coding, Compliance: Increased risk of audit and compliance issues, Data Quality: Decreased data quality and specificity
Mitigation Strategy
Query the provider to specify the site for more accurate coding.
Impact
Using A59.9 increases audit risk due to lack of specificity.
Mitigation Strategy
Encourage site-specific documentation and use of specific codes.
Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.
