WHO's Classification System for Health Conditions and Violence Reporting

The classification family developed by the World Health Organization (WHO) and its International Network of Classifications is based on scientific and classification principles, internationally applicable, and addresses the multidimensional aspects of health and various user needs.

WHO's classifications cover key health system parameters like mortality, disease, functioning, disability, health, and health-related interventions. These reference classifications are the result of international consensus, widely accepted and recommended for use in health reporting. Notably, the ICD-10 serves as a reference classification, while ICPC-2-R (International Classification of Primary Care) is used in primary healthcare.

ICPC-2-R is a widely adopted tool in primary healthcare for organizing clinical information in family medicine. It has a dual structure: one axis includes 17 chapters organized by body systems with an alphabetical code, and the other axis includes rubrics with a two-digit code. ICPC simplifies coding for health records.
ICD-10, the International Classification of Diseases, aims to facilitate systematic registration, analysis, and interpretation of morbidity and mortality data across different countries and times. ICD-10 allows diagnoses to be converted into alphanumeric codes, enabling easy storage, retrieval, and analysis of health data. It is the international diagnostic standard, and child abuse coding guidelines are covered in ICD-10 classes XIX and XX.

• Class XIX - Injury, Poisoning, and External Causes: Used for recording conditions caused by trauma or poisoning, detailing both the nature of the condition and its circumstances. The S and T sections include trauma types, with S-section coding injuries to specific body parts and T-section for multiple or unspecified injuries, poisoning, and effects of external causes.

• Class XX - External Causes of Morbidity and Mortality: This class allows qualification of cases, conditions, and circumstances leading to injuries or poisoning. Codes V01-Y98 are supplementary and clarify the nature of the condition, often used with class XIX codes.

In cases of confirmed or suspected violence, the following codes apply:

• T74 - Confirmed abuse, neglect, or maltreatment of adults and children.
• T76 - Suspected abuse, neglect, or maltreatment of adults and children.
If the perpetrator is identified, code Y07 (perpetrator) is added.

Coding for Child Abuse in ICPC-2 and ICD-10:

• Child Relationship Problems
o ICPC-2: Z16
o ICD-10: T74.0, T74.3, Z61, Z62, Z63.8
o Implies emotional abuse; does not include physical abuse (Z25).
• Post-violence/Life-threatening Episode Issues
o ICPC-2: Z25
o ICD-10: T74.1, T74.2, T74.8, T74.9, Z65.4, Z65.5
o Includes victims of physical violence, rape, or sexual assault; excludes emotional abuse (Z12), physical abuse (Z13), or emotional abuse of a child (Z1).
Key Points for Coding
• ICD-10 has a more granular structure, often matching one or more ICPC-2 rubrics.
• Accurate classification and timely reporting of abuse cases can facilitate appropriate interventions and support for the affected individual.
