| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| Z22.7 | Carrier of latent tuberculosis | Use when latent TB is confirmed and is the focus of care. |

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

Decision Criteria
clinical Criteria
- Positive IGRA or TST with normal CXR and no symptoms
Applicable To
- Confirmed latent TB infection
Excludes
- Active tuberculosis (A15-A19)
Clinical Validation Requirements
- Positive IGRA or TST
- Normal chest X-ray
- Absence of active TB symptoms
Code-Specific Risks
- Incorrectly using for active TB cases
Coding Notes
- Ensure documentation includes test type and results, and normal imaging findings.
Z11.7 - Encounter for screening for latent tuberculosis
Use for encounters specifically for latent TB testing.
Applicable To
- Screening for latent TB
Excludes
- Screening for active TB (Z11.1)
Clinical Validation Requirements
- Order for IGRA or TST without prior diagnosis
Coding Notes
Ensure documentation specifies the purpose of the encounter as screening.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Latent Tuberculosis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code Z22.7.
Impact
Clinical: Potential misdiagnosis, Regulatory: Non-compliance with coding guidelines, Financial: Claim denials
Mitigation Strategy
Always include imaging results in documentation
Impact
Reimbursement: Potential claim denials, Compliance: Non-compliance with coding standards, Data Quality: Inaccurate patient records
Mitigation Strategy
Confirm latent TB status with appropriate tests and imaging.
Impact
Using Z22.7 without confirming latent TB status
Mitigation Strategy
Ensure all diagnostic criteria are met and documented.
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.
