Contents

During some health encounters it may not be appropriate to use a code from Chapters I-XIX. As such codes from this chapter can be used in the primary diagnosis field when they represent the reason for which the encounter has taken place. Situations where this may be appropriate include: when a patient receives limited care or service for an ongoing condition (for example a patient in remission undergoing maintenance chemotherapy); to donate an organ and/or tissue; to receive prophylactic immunization; to discuss a problem other than a disease or injury; and for a situation or problem that influences the person's health status (that is not currently an illness or injury).

Should local coding rules permit, codes from Chapter XXI can also be used in addition to codes from other chapters. Instances might include the capturing of statuses and previously resolved conditions impacting upon the current encounter. For example, a patient with a history of colorectal cancer treated with a colectomy, now presenting with abdominal adhesions.

Persons encountering health services for examination and investigation (Z00–Z13)

Persons encountering health services for specific procedures and health care (Z40–Z54)

Persons encountering health services in other circumstances (Z70–Z76)

The International Classification of Diseases (ICD) is a globally used diagnostic tool for epidemiology, health management and clinical purposes. The ICD is maintained by the World Health Organization (WHO), which is the directing and coordinating authority for health within the United Nations System. The ICD is originally designed as a health care classification system, providing a system of diagnostic codes for classifying diseases, including nuanced classifications of a wide variety of signs, symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or disease. This system is designed to map health conditions to corresponding generic categories together with specific variations, assigning for these a designated code, up to six characters long. Thus, major categories are designed to include a set of similar diseases.

Prenatal care Regular check-ups that allow doctors or midwives to treat and prevent potential health problems throughout the course of the pregnancy

Prenatal care, also known as antenatal care, is a type of preventive healthcare. Its goal is to provide regular check-ups that allow doctors or midwives to treat and prevent potential health problems throughout the course of the pregnancy and to promote healthy lifestyles that benefit both mother and child. During check-ups, pregnant women receive medical information over maternal physiological changes in pregnancy, biological changes, and prenatal nutrition including prenatal vitamins. Recommendations on management and healthy lifestyle changes are also made during regular check-ups. The availability of routine prenatal care, including prenatal screening and diagnosis, has played a part in reducing the frequency of maternal death, miscarriages, birth defects, low birth weight, neonatal infections and other preventable health problems.

Physical examination Process by which a medical professional investigates the body of a patient for signs of disease

In a physical examination, medical examination, or clinical examination, a medical practitioner examines a patient for any possible medical signs or symptoms of a medical condition. It generally consists of a series of questions about the patient's medical history followed by an examination based on the reported symptoms. Together, the medical history and the physical examination help to determine a diagnosis and devise the treatment plan. This data then becomes part of the medical record.

Preventive healthcare Prevent and minimize the occurrence of diseases

Preventive healthcare, or prophylaxis, consists of measures taken for disease prevention. Disease and disability are affected by environmental factors, genetic predisposition, disease agents, and lifestyle choices and are dynamic processes which begin before individuals realize they are affected. Disease prevention relies on anticipatory actions that can be categorized as primal, primary, secondary, and tertiary prevention.

The Current Procedural Terminology (CPT) code set is a medical code set maintained by the American Medical Association through the CPT Editorial Panel. The CPT code set describes medical, surgical, and diagnostic services and is designed to communicate uniform information about medical services and procedures among physicians, coders, patients, accreditation organizations, and payers for administrative, financial, and analytical purposes.

Screening (medicine) brief evaluation to detect unnoticed health problems

Screening, in medicine, is a strategy used to look for as-yet-unrecognised conditions or risk markers. This testing can be applied to individuals or to a whole population. The people tested may not exhibit any signs or symptoms of a disease, or they might exhibit only one or two symptoms, which by themselves do not indicate a definitive diagnosis.

The ICD-11 is the eleventh revision of the International Classification of Diseases. It will eventually replace the ICD-10 as the global standard for coding health information and causes of death. The ICD-11 is developed and regularly updated by the World Health Organization (WHO). Its development spanned over a decade of work, involving over 300 specialists from 55 countries divided into 30 work groups, with an additional 10,000 proposals from people all over the world. Following an alpha version in May 2011 and a beta draft in May 2012, a stable version of the ICD-11 was released on 18 June 2018, and officially endorsed by all WHO members during the 72nd World Health Assembly on 25 May 2019.

The ICD-10-CM is a morbidity classification for classifying diagnoses and reason for visits in all American health care settings. The ICD-10-CM is based on the ICD-10, the statistical classification of disease published by the World Health Organization (WHO) which replaces ICD-9.
