The Z11.1 Diagnosis Code, officially known as “Encounter for screening for respiratory tuberculosis,” is a critical component of the International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) system. Used within the healthcare industry, particularly in medical billing and coding, Z11.1 signifies an encounter specifically for screening purposes to detect respiratory tuberculosis. This code is instrumental in tracking and managing public health efforts aimed at controlling and preventing the spread of tuberculosis.

As a billable and specific code, Z11.1 is recognized for reimbursement purposes, meaning healthcare providers can use this code to claim for services rendered during tuberculosis screening encounters. The code’s specificity ensures that the encounter is indeed for screening and not for diagnosing or treating existing tuberculosis. The 2025 edition of ICD-10-CM, which includes Z11.1, became effective on October 1, 2024, ensuring its current relevance in medical coding practices. It’s important to note that while Z11.1 is the American ICD-10-CM version, international versions of ICD-10 Z11.1 might have variations, emphasizing the need for accurate regional coding.
The application of the Z11.1 code is specifically for “Encounter for screening for active tuberculosis disease.” This clarifies that the screening is aimed at identifying active cases of tuberculosis, which are infectious and require immediate medical attention. This code is applicable in various screening scenarios, including routine health check-ups, targeted screenings for high-risk populations, or as part of public health initiatives.
Several approximate synonyms are associated with Z11.1, such as “Screening for pulmonary tuberculosis (tb of the lung)” and “Screening for pulmonary tuberculosis done.” These synonyms provide clarity and ease of understanding when healthcare professionals are documenting or searching for the appropriate code. The term “pulmonary tuberculosis” specifically refers to tuberculosis affecting the lungs, which is the most common form of respiratory tuberculosis.
In the context of Present On Admission (POA) reporting, Z11.1 is considered exempt. POA is defined as conditions present at the time of inpatient admission order. Exemption from POA reporting for Z11.1 implies that whether the screening encounter occurred before or during admission is not a critical factor for reporting purposes, simplifying the administrative process associated with this code.
ICD-10-CM code Z11.1 is categorized within Diagnostic Related Groups (MS-DRG v42.0), which are used to classify hospital cases and determine payment. This grouping helps in standardizing healthcare payments and analyzing healthcare utilization related to tuberculosis screening encounters.
Looking at the code history, Z11.1 was introduced in 2016 and has remained unchanged through the 2025 edition. This stability indicates a consistent and long-standing need for this specific code in the ICD-10-CM system for accurately documenting and tracking respiratory tuberculosis screening encounters over the years. The consistent nature of the code across multiple editions reinforces its importance in long-term data collection and epidemiological studies related to tuberculosis control.
Understanding the Z11.1 diagnosis code is crucial for healthcare providers, medical coders, and public health officials involved in tuberculosis prevention and control efforts. Accurate use of this code ensures proper medical billing, facilitates data collection for public health surveillance, and ultimately contributes to effective management of respiratory tuberculosis.
