Z11.0

Encounter for screening for intestinal infectious diseases

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/12/2025

Code Description

ICD-10 Z11.0 is a billable code used to indicate a diagnosis of encounter for screening for intestinal infectious diseases.

Key Diagnostic Point:

Z11.0 is used to indicate an encounter for screening for intestinal infectious diseases, which includes conditions such as bacterial, viral, or parasitic infections affecting the gastrointestinal tract. This code is particularly relevant in preventive care settings where individuals may be screened due to risk factors such as travel history, exposure to contaminated food or water, or living in areas with endemic diseases. Social determinants of health, such as socioeconomic status, access to clean water, and sanitation facilities, play a crucial role in the prevalence of these diseases. Preventive screenings can help identify asymptomatic infections early, allowing for timely intervention and management. This code is essential for tracking public health trends and ensuring that at-risk populations receive appropriate preventive services.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of intestinal infectious diseases that may require different screening protocols.
  • Need for thorough documentation of risk factors and patient history.
  • Potential overlap with other Z codes related to screening and preventive care.
  • Variability in payer requirements for coverage of screening services.

Audit Risk Factors

  • Inadequate documentation of patient history and risk factors.
  • Failure to link the screening encounter to appropriate preventive services.
  • Incorrect sequencing of Z codes with primary diagnosis codes.
  • Misinterpretation of screening guidelines leading to inappropriate code assignment.

Specialty Focus

Medical Specialties

Primary Care

Documentation Requirements

Documentation should include patient history, risk factors, and any symptoms present. Screening results must be recorded.

Common Clinical Scenarios

Routine checkups where patients are screened for intestinal infections, especially after travel or exposure.

Billing Considerations

Consideration of social determinants such as access to healthcare, sanitation, and dietary habits.

Public Health

Documentation Requirements

Population-level data collection and surveillance documentation are necessary for tracking disease prevalence.

Common Clinical Scenarios

Epidemiological studies and community health screenings aimed at preventing outbreaks.

Billing Considerations

Focus on health education and community resources to address social determinants.

Coding Guidelines

Inclusion Criteria

Use Z11.0 When
  • Z codes are used when a patient is not currently ill but is seeking preventive services
  • 0 should be sequenced appropriately, often as a secondary code following a primary diagnosis
  • Payer requirements may vary, so it is essential to verify coverage for screening services

Exclusion Criteria

Do NOT use Z11.0 When
No specific exclusions found.
