CodeDescriptionWhen to UseKey Documentation
Z11.1Encounter for screening for respiratory tuberculosisUse for asymptomatic patients undergoing routine TB screening.
  • Patient presents for routine screening without symptoms.
  • Documentation of screening purpose, e.g., employment or immigration.
Z11.7Encounter for testing for latent tuberculosis infectionUse for patients with a history of positive TST undergoing further testing.
  • Patient has a history of positive TST and requires further evaluation.
  • Documentation of testing purpose, e.g., follow-up or serial testing.

Clinical Decision Support

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

Applicable To

  • Pre-employment screenings
  • Immigration physicals

Excludes

Clinical Validation Requirements

  • Patient presents for routine screening without symptoms.
  • Documentation of screening purpose, e.g., employment or immigration.

Code-Specific Risks

  • Incorrectly using for symptomatic patients.

Coding Notes

  • Ensure documentation specifies the screening nature of the encounter.

Ancillary Codes

Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Nonspecific reaction to tuberculin skin test without active tuberculosis

R76.11
Use when TST is positive but no active TB is confirmed.

Nonspecific reaction to gamma interferon test without active tuberculosis

R76.12
Use when IGRA is positive but no active TB is confirmed.

Differential Codes

Alternative codes to consider when ruling out similar conditions to the primary diagnosis.

Tuberculosis of lung

A15.0
Use A15.0 when active TB is confirmed with symptoms and positive diagnostic tests.

Respiratory tuberculosis unspecified

A15.9
Use A15.9 when active TB is suspected or confirmed.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Tuberculosis Test to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code Z11.1.

Impact

Clinical: Inability to determine test positivity., Regulatory: Non-compliance with documentation standards., Financial: Potential claim denials due to insufficient documentation.

Mitigation Strategy

Train staff on proper documentation of TST results., Use templates that prompt for induration size.

Impact

Reimbursement: Incorrect coding may lead to claim denials., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate patient records and data reporting.

Mitigation Strategy

Use A15 codes for symptomatic patients with suspected active TB.

Impact

Using screening codes for symptomatic patients.

Mitigation Strategy

Regular training on code selection criteria.

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.
