XXII: Codes for special purposes
The group of medical conditions categorized under Codes for Special Purposes (also known as Chapter XXII in ICD-10 WHO 2016) constitutes a wide range of disorders that do not fit elsewhere in the standard disease classification system. These conditions often result from unique or rare circumstances and can present in various ways. For instance, this category includes illnesses related to war or military operations, legal interventions, and sequelae, which are complications or conditions that arise as a direct result of a previous disease or injury. Other conditions under this chapter are related to external causes like complications of medical and surgical procedures or other healthcare management. Symptoms, progression, and affected bodily systems can vastly differ based on the specific condition. Transmission of these conditions largely depends on the nature of the external cause leading to the health issue. Despite their varied presentations, all these conditions share the commonality of usually being outside the typical spectrum of diseases and injuries.
