ICD-10 is the 10th revision of the International Classification of Diseases (ICD), a medical classification list by the World Health Organization (WHO). It contains codes for diseases, signs and symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or diseases. Work on ICD-10 began in 1983, became endorsed by the Forty-third World Health Assembly in 1990, and came into effect in member states on 1 January 1993. It was replaced by ICD-11 on January 1, 2022.
46-546: While WHO manages and publishes the base version of the ICD, several member states have modified it to better suit their needs. In the base classification, the code set allows for more than 14,000 different codes and permits the tracking of many new diagnoses compared to the preceding ICD-9 . Through the use of optional sub-classifications, ICD-10 allows for specificity regarding the cause, manifestation, location, severity, and type of injury or disease. The adapted versions may differ in
92-495: A diagnosis of exclusion . Even if it does not result in a single probable disease or condition, it can at least rule out any imminently life-threatening conditions. Unless the provider is certain of the condition present, further medical tests, such as medical imaging, are performed or scheduled in part to confirm or disprove the diagnosis but also to document the patient's status and keep the patient's medical history up to date. If unexpected findings are made during this process,
138-480: A process of elimination or at least of rendering the entries more or less probable by further medical tests and other processing, aiming to reach the point where only one candidate disease or condition remains as probable. The result may also remain a list of possible conditions, ranked in order of probability or severity. Such a list is often generated by computer-aided diagnosis systems. The resultant diagnostic opinion by this method can be regarded more or less as
184-402: A brief summation or an extensive formulation, even taking the form of a story or metaphor. It might be a means of communication such as a computer code through which it triggers payment, prescription, notification, information or advice. It might be pathogenic or salutogenic . It is generally uncertain and provisional. Once a diagnostic opinion has been reached, the provider is able to propose
230-523: A different therapy so it may be limited to cases where no diagnosis can be made. The term diagnostic criteria designates the specific combination of signs and symptoms , and test results that the clinician uses to attempt to determine the correct diagnosis. Some examples of diagnostic criteria, also known as clinical case definitions , are: Clinical decision support systems are interactive computer programs designed to assist health professionals with decision-making tasks. The clinician interacts with
276-490: A disease is diagnosed correctly, but the diagnosis is irrelevant. A correct diagnosis may be irrelevant because treatment for the disease is not available, not needed, or not wanted. Most people will experience at least one diagnostic error in their lifetime, according to a 2015 report by the National Academies of Sciences, Engineering, and Medicine . Causes and factors of error in diagnosis are: When making
322-457: A management plan, which will include treatment as well as plans for follow-up. From this point on, in addition to treating the patient's condition, the provider can educate the patient about the etiology , progression, prognosis , other outcomes, and possible treatments of her or his ailments, as well as providing advice for maintaining health. A treatment plan is proposed which may include therapy and follow-up consultations and tests to monitor
368-619: A medical diagnosis, a lag time is a delay in time until a step towards diagnosis of a disease or condition is made. Types of lag times are mainly: Long lag times are often called "diagnostic odyssey". The first recorded examples of medical diagnosis are found in the writings of Imhotep (2630–2611 BC) in ancient Egypt (the Edwin Smith Papyrus ). A Babylonian medical textbook, the Diagnostic Handbook written by Esagil-kin-apli ( fl. 1069–1046 BC), introduced
414-495: A need for codes with improved clinical accuracy and specificity. The alphanumeric coding in ICD-10 is an improvement from ICD-9 which had a limited number of codes and a restrictive structure. Early concerns in the implementation of ICD-10 included the cost and the availability of resources for training healthcare workers and professional coders. Medical diagnosis Medical diagnosis (abbreviated Dx , D x , or D s )
460-414: A number of methods or techniques that can be used in a diagnostic procedure, including performing a differential diagnosis or following medical algorithms . In reality, a diagnostic procedure may involve components of multiple methods. The method of differential diagnosis is based on finding as many candidate diseases or conditions as possible that can possibly cause the signs or symptoms, followed by
506-436: A number of ways, and some national editions have expanded the code set even further; with some going so far as to add procedure codes . ICD-10-CM , for example, has over 70,000 codes. The WHO provides detailed information regarding the ICD via its website – including an ICD-10 online browser and ICD training materials. The online training includes a support forum, a self-learning tool and user guide. The following table lists

#1732773012932552-420: A result of an incidental finding of a sign unrelated to the parameter of interest, such as can occur in comprehensive tests such as radiological studies like magnetic resonance imaging or blood test panels that also include blood tests that are not relevant for the ongoing diagnosis. General components which are present in a diagnostic procedure in most of the various available methods include: There are
598-557: A year before that on October 1, 2013. All HIPAA "covered entities" were required to make the change; a pre-requisite to ICD-10-CM is the adoption of EDI Version 5010 by January 1, 2012. Enforcement of 5010 transition by the Centers for Medicare & Medicaid Services (CMS), however, was postponed by CMS until March 31, 2012, with the federal agency citing numerous factors, including slow software upgrades. The implementation of ICD-10-CM has been subject to previous delays. In January 2009,

690-459: Is not the same as the individual's diagnosis.) A total evaluation of a condition is often termed a diagnostic workup. A diagnostic procedure may be performed by various healthcare professionals such as a physician , physiotherapist , dentist , podiatrist , optometrist , nurse practitioner , healthcare scientist or physician assistant . This article uses diagnostician as any of these person categories. A diagnostic procedure (as well as
736-425: Is the process of determining which disease or condition explains a person's symptoms and signs . It is most often referred to as a diagnosis with the medical context being implicit. The information required for a diagnosis is typically collected from a history and physical examination of the person seeking medical care. Often, one or more diagnostic procedures , such as medical tests , are also done during
782-564: The Greek word διάγνωσις ( diágnōsis ) from διαγιγνώσκειν ( diagignṓskein ), meaning "to discern, distinguish". Diagnosis can take many forms. It might be a matter of naming the disease, lesion, dysfunction or disability. It might be a management-naming or prognosis-naming exercise. It may indicate either degree of abnormality on a continuum or kind of abnormality in a classification. It is influenced by non-medical factors such as power, ethics and financial incentives for patient or doctor. It can be
828-409: The correlation of various pieces of information followed by the recognition and differentiation of patterns. Occasionally the process is made easy by a sign or symptom (or a group of several) that is pathognomonic . Diagnosis is a major component of the procedure of a doctor's visit . From the point of view of statistics , the diagnostic procedure involves classification tests . A diagnosis, in
874-413: The 2013 German Amendment of ICD-10 (ICD-10-GM), and a systematic catalog of codes of medical procedures called Greek Medical Procedure Classification (GMPC), based on corresponding international procedural classification. Hungary introduced the use of ICD-10 from January 1, 1996, via a ministerial decree. A Korean modification has existed since 2008. The Dutch translation of ICD-10 is ICD10-nl, which
920-683: The ATIH. Germany 's ICD-10 German Modification (ICD-10-GM) is based on ICD-10-AM. ICD-10-GM was developed between 2003 and 2004, by the German Institute for Medical Documentation and Information . Greece introduced ICD-10 on December 23, 2023. The Greek DRG (Gr-DRG) system is based on the Greek modification of the International Statistical Classification of Diseases and Related Health Problems, based on
966-669: The ICD-10 Clinical Modification (ICD-10-CM). A procedural classification called ICD-10 Procedure Coding System (ICD-10-PCS) has also been developed for capturing inpatient procedures. The ICD-10-CM and ICD-10-PCS were developed by the Centers for Medicare and Medicaid Services (CMS) and the National Center for Health Statistics (NCHS). There are over 70,000 ICD-10-PCS procedure codes and over 69,000 ICD-10-CM diagnosis codes, compared to about 3,800 procedure codes and roughly 14,000 diagnosis codes found in
SECTION 20
#17327730129321012-709: The ICD-10 for Brazilian Portuguese was started around 1986. Brazil was designated the Field Trial Coordinating Centre for field testing of the list's Chapter V, and the translation was then updated and modified by several contributors across the country. One of the final versions was proofread by J. Leme Lopes, and the final translation was created directly from the English-language version in 1992. Canada began using ICD-10 for mortality reporting in 2000. A six-year, phased implementation of ICD-10-CA for morbidity reporting began in 2001. It
1058-445: The actual process of making a diagnosis is a cognitive process. A clinician uses several sources of data and puts the pieces of the puzzle together to make a diagnostic impression. The initial diagnostic impression can be a broad term describing a category of diseases instead of a specific disease or condition. After the initial diagnostic impression, the clinician obtains follow up tests and procedures to get more data to support or reject
1104-797: The base classification in the level of detail, incomplete adoption of a category, or the addition of procedure codes . Introduced in 1998, ICD-10 Australian Modification (ICD-10-AM) was developed by the National Centre for Classification in Health at the University of Sydney . It is currently maintained by the Australian Consortium for Classification Development. ICD-10-AM has also been adopted by New Zealand , Ireland , Saudi Arabia and several other countries. Brazil introduced ICD-10 in 1996. The provisional translation of
1150-494: The chapter number (using Roman numerals ), the code range of each chapter, and the chapter's title from the international version of the ICD-10. Approximately 27 countries use ICD-10 for reimbursement and resource allocation in their health system, and some have made modifications to ICD to better accommodate its utility. The unchanged international version of ICD-10 is used in 117 countries for performing cause of death reporting and statistics. The national versions may differ from
1196-428: The condition and the progress of the treatment, if needed, usually according to the medical guidelines provided by the medical field on the treatment of the particular illness. Relevant information should be added to the medical record of the patient. A failure to respond to treatments that would normally work may indicate a need for review of the diagnosis. Nancy McWilliams identifies five reasons that determine
1242-693: The date was pushed back to October 1, 2013, rather than an earlier proposal of October 1, 2011. Two common complaints in the United States about the ICD-10-CM are 1) the long list of potentially relevant codes for a given condition (such as rheumatoid arthritis ) which can be confusing and reduce efficiency and 2) the assigned codes for seldom seen conditions (e.g. W55.22XA: Struck by cow, initial encounter; and V91.07XA: Burn due to water-skis on fire, initial encounter). The expansion of healthcare delivery systems and changes in global health trends prompted
1288-568: The decision. Other methods that can be used in performing a diagnostic procedure include: Diagnosis problems are the dominant cause of medical malpractice payments, accounting for 35% of total payments in a study of 25 years of data and 350,000 claims. Overdiagnosis is the diagnosis of "disease" that will never cause symptoms or death during a patient's lifetime. It is a problem because it turns people into patients unnecessarily and because it can lead to economic waste ( overutilization ) and treatments that may cause harm. Overdiagnosis occurs when
1334-485: The financial and public health cost associated with continuing to use the ICD-9-CM was too high and mandated the switch to ICD-10-CM. The deadline for the United States to begin using ICD-10-CM for diagnosis coding and Procedure Coding System ICD-10-PCS for inpatient hospital procedure coding was set at October 1, 2015, a year later than the previous 2014 deadline. Before the 2014 deadline, the previous deadline had been
1380-428: The initial hypothesis may be ruled out and the provider must then consider other hypotheses. In a pattern recognition method the provider uses experience to recognize a pattern of clinical characteristics. It is mainly based on certain symptoms or signs being associated with certain diseases or conditions, not necessarily involving the more cognitive processing involved in a differential diagnosis. This may be

1472-652: The opinion reached thereby) does not necessarily involve elucidation of the etiology of the diseases or conditions of interest, that is, what caused the disease or condition. Such elucidation can be useful to optimize treatment, further specify the prognosis or prevent recurrence of the disease or condition in the future. The initial task is to detect a medical indication to perform a diagnostic procedure. Indications include: Even during an already ongoing diagnostic procedure, there can be an indication to perform another, separate, diagnostic procedure for another, potentially concomitant, disease or condition. This may occur as
1518-418: The original diagnosis and will attempt to narrow it down to a more specific level. Diagnostic procedures are the specific tools that the clinicians use to narrow the diagnostic possibilities. The plural of diagnosis is diagnoses . The verb is to diagnose, and a person who diagnoses is called a diagnostician . The word diagnosis / d aɪ . ə ɡ ˈ n oʊ s ɪ s / is derived through Latin from
1564-478: The output of a heart monitor. Such automated processes are usually deemed a "device" by the FDA and require regulatory approval. In contrast, clinical decision support systems that "support" but do not replace the clinician are deemed to be "Augmented Intelligence" if it meets the FDA criteria that (1) it reveals the underlying data, (2) reveals the underlying logic, and (3) leaves the clinician in charge to shape and make
1610-586: The previous ICD-9-CM. There was much controversy when the transition from the ICD-9-CM to the ICD-10-CM was first announced in the US. Many providers were concerned about the vast number of codes being added, the complexity of the new coding system, and the costs associated with the transition. The Centers for Medicare and Medicaid Services (CMS) weighed these concerns against the benefits of having more accurate data collection, clearer documentation of diagnoses and procedures, and more accurate claims processing. CMS decided
1656-416: The primary method used in cases where diseases are "obvious", or the provider's experience may enable him or her to recognize the condition quickly. Theoretically, a certain pattern of signs or symptoms can be directly associated with a certain therapy, even without a definite decision regarding what is the actual disease, but such a compromise carries a substantial risk of missing a diagnosis which actually has
1702-462: The process. Sometimes the posthumous diagnosis is considered a kind of medical diagnosis. Diagnosis is often challenging because many signs and symptoms are nonspecific . For example, redness of the skin ( erythema ), by itself, is a sign of many disorders and thus does not tell the healthcare professional what is wrong. Thus differential diagnosis , in which several possible explanations are compared and contrasted, must be performed. This involves
1748-405: The sense of diagnostic procedure, can be regarded as an attempt at classification of an individual's condition into separate and distinct categories that allow medical decisions about treatment and prognosis to be made. Subsequently, a diagnostic opinion is often described in terms of a disease or other condition. (In the case of a wrong diagnosis, however, the individual's actual disease or condition
1794-402: The software utilizing both the clinician's knowledge and the software to make a better analysis of the patients data than either human or software could make on their own. Typically the system makes suggestions for the clinician to look through and the clinician picks useful information and removes erroneous suggestions. Some programs attempt to do this by replacing the clinician, such as reading
1840-483: The use of empiricism , logic and rationality in the diagnosis of an illness or disease . Traditional Chinese Medicine , as described in the Yellow Emperor's Inner Canon or Huangdi Neijing , specified four diagnostic methods: inspection, auscultation-olfaction, inquiry and palpation . Hippocrates was known to make diagnoses by tasting his patients' urine and smelling their sweat. Medical diagnosis or
