Z22.338

Carrier of other streptococcus

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

Code Description

ICD-10 Z22.338 is a billable code used to indicate a diagnosis of carrier of other streptococcus.

Key Diagnostic Point:

Z22.338 is used to identify individuals who are carriers of other types of streptococcus bacteria, which may not cause illness in the carrier but can be transmitted to others, potentially leading to infections. This code is significant in preventive care as it highlights the need for monitoring and education regarding the transmission of streptococcal infections. Social determinants of health, such as access to healthcare, socioeconomic status, and living conditions, can influence the likelihood of being a carrier and the subsequent health outcomes. Preventive measures, including vaccinations and hygiene education, are essential in managing the spread of these bacteria. Screening for carriers is crucial in community health settings, particularly in environments like schools and daycare centers where transmission risk is higher. Aftercare may involve follow-up assessments to ensure that carriers are informed about their status and understand the implications for their health and the health of those around them.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Need for thorough documentation of carrier status and potential exposure.
  • Differentiation from other streptococcal infections.
  • Understanding of social determinants affecting carrier status.
  • Potential for co-morbid conditions that may complicate coding.

Audit Risk Factors

  • Inadequate documentation of carrier status.
  • Failure to link Z code with appropriate preventive measures.
  • Misclassification of carrier status as an active infection.
  • Lack of follow-up documentation for carriers.

Specialty Focus

Medical Specialties

Primary Care

Documentation Requirements

Documentation should include patient history, risk factors for streptococcal infections, and any preventive measures taken.

Common Clinical Scenarios

Routine checkups where carrier status is assessed, screenings for streptococcal infections, and aftercare follow-ups.

Billing Considerations

Consideration of social determinants such as living conditions and access to healthcare services that may affect carrier status.

Public Health

Documentation Requirements

Documentation should focus on population-level data, including prevalence of carriers and transmission rates.

Common Clinical Scenarios

Epidemiological studies, community health screenings, and preventive health initiatives.

Billing Considerations

Importance of tracking health status and implementing community-wide preventive measures.

Coding Guidelines

Inclusion Criteria

Use Z22.338 When
  • Z codes are used to indicate a patient's health status or contact with health services rather than a specific illness
  • When coding Z22
  • 338, it should be sequenced appropriately based on the primary reason for the visit
  • Payer requirements may vary, so it's essential to check specific guidelines for coverage

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for greater specificity in coding carrier status, which aids in better tracking and management of public health concerns related to streptococcus.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for greater specificity in coding carrier status, which aids in better tracking and management of public health concerns related to streptococcus.

Reimbursement & Billing Impact

The transition to ICD-10 has allowed for greater specificity in coding carrier status, which aids in better tracking and management of public health concerns related to streptococcus.
