ICD-10: Z11.9

The ICD-10 code Z11.9 refers to an encounter for screening for infectious and parasitic diseases, unspecified. This code is part of the Z codes, which are used to represent encounters for circumstances other than a disease or injury. Here’s a detailed overview of this code, including its clinical description, usage, and guidelines.

Clinical Description

Definition

Z11.9 is specifically designated for situations where a patient is undergoing screening for infectious and parasitic diseases, but the specific disease or condition is not identified. This can include a variety of tests and evaluations aimed at detecting potential infections or parasitic infestations before symptoms manifest.

Context of Use

This code is typically used in outpatient settings, such as primary care or preventive health services, where patients may be screened as part of routine health checks or specific public health initiatives. It is important to note that this code does not specify any particular infectious or parasitic disease, making it a broad category for screening encounters.

Clinical Guidelines

When to Use Z11.9

• Routine Screening: It can be applied when patients are screened as part of a routine health examination, especially in populations at risk for certain infections.
