Understanding ICD-11 Code QA00.5: Research Comparison Examinations

The ICD-11 code QA00.5, officially designated as "Examination for normal comparison or control in clinical research programme," is used to classify encounters where an individual undergoes a medical examination specifically for the purpose of serving as a normal comparison or control within a clinical research study. This code applies when the individual has no current complaints or reported diagnosis that would interfere with their role as a baseline or control participant. It signifies a health status assessment for research protocols.

Accurate Documentation for QA00.5 Encounters

When documenting encounters classified under ICD-11 code QA00.5, healthcare providers should clearly indicate that the examination is for research purposes, specifically as a normal comparison or control. This code is distinct from examinations for diagnosing or treating an illness. Proper documentation ensures accurate medical records and facilitates correct billing and statistical reporting for clinical research programmes.

Billability and Reporting of ICD-11 Code QA00.5

ICD-11 code QA00.5 falls within Chapter 24, "Factors influencing health status or contact with health services." Codes in this chapter are often reportable for administrative and statistical purposes, particularly when an individual's contact with health services is not due to illness or injury. The billability of QA00.5 typically depends on the specific clinical research protocol, payer agreements, and institutional policies governing research participation. It is generally used for examinations conducted as part of a research study's design.

Alternative Terminology for QA00.5

While QA00.5 is the official ICD-11 designation, healthcare professionals may encounter or use related terms such as:

• Normal control examination for research
• Clinical research participant screening
• Study comparison subject examination
• Baseline assessment for clinical trial
• Examination for research control group

Scope of QA00.5: When to Use Other Codes

ICD-11 code QA00.5 is specifically for individuals participating in clinical research as a normal comparison or control, who present without active complaints or diagnosed conditions relevant to the study. If a patient presents with symptoms, signs, or a diagnosed condition that requires medical attention or is relevant to the research being conducted, a different, more specific ICD-11 code should be used to accurately reflect their health status or reason for encounter. This code is not intended for the diagnosis or management of illness.

Associated ICD-11 Codes for Examinations

The primary ICD-11 code for this specific research-related examination is QA00.5. This code is part of the broader category QA00, "General examination or investigation of persons without complaint or reported diagnosis." Other related codes within this chapter may include QA00.0 for general adult medical examinations or QA00.8 for special screening examinations for infectious diseases, depending on the specific context of the health service contact.
