The International Classification of Diseases, Tenth Edition (ICD-10), is a clinical cataloging system that went into effect for the U.S. healthcare industry on Oct. 1, 2015, after a series of lengthy delays.
ICD-10 is the 10th revision of the International Statistical Classification of Diseases and Related Health Problems (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.
Why ICD-10 codes are important
ICD-10 refers to the tenth edition of the International Classification of Diseases, which is a medical coding system chiefly designed by the World Health Organization (WHO) to catalog health conditions by categories of similar diseases under which more specific conditions are listed, thus mapping nuanced diseases to broader morbidities.
International Classification of Diseases, (ICD-10-CM/PCS) Transition - Background.
ICD-10 code Z71. 9 for Counseling, unspecified is a medical classification as listed by WHO under the range - Factors influencing health status and contact with health services .
ICD-9/ICD-10 are acronyms used in the medical field that stand for International Classification of Diseases, ninth/tenth revision. ICD diagnosis codes submitted by RREs on Section 111 Claim Input Files are used by Medicare claims paying offices to help process Medicare claims.
ICD-10 code R68. 89 for Other general symptoms and signs is a medical classification as listed by WHO under the range - Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified .
09 for Observation of other suspected mental condition is a medical classification as listed by WHO under the range -PERSONS WITHOUT REPORTED DIAGNOSIS ENCOUNTERED DURING EXAMINATION AND INVESTIGATION.
The patient's primary diagnostic code is the most important. Assuming the patient's primary diagnostic code is Z76. 89, look in the list below to see which MDC's "Assignment of Diagnosis Codes" is first. That is the MDC that the patient will be grouped into.

Category codes are user defined codes to which you can assign a title and a value. The title appears on the appropriate screen next to the field in which you type the code.
ICD-10 refers to the tenth edition of the International Classification of Diseases, which is a medical coding system chiefly designed by the World Health Organization (WHO) to catalog health conditions by categories of similar diseases under which more specific conditions are listed, thus mapping nuanced diseases to broader morbidities.
The Origins of ICD-10 Coding. The roots of ICD-10 coding go back to the 1850s. The first edition, known as the International List of Causes of Death, was adopted by the International Statistical Institute in 1893.
The ICD-10 codes we use today are more specific than ICD-9-CM codes and allow for detailed classifications of patients’ conditions, injuries, and diseases. Medical coders are now equipped to capture anatomic sites, etiologies, comorbidities and complications, as well as severity of illnesses.
ICD-10-CM codes consist of three to seven characters. Every code begins with an alpha character, which is indicative of the chapter to which the code is classified. The second and third characters are numbers. The fourth, fifth, sixth, and seventh characters can be numbers or letters.
Similar to the Table of Neoplasms, the Table of Drugs and Chemicals allows you to locate codes for poisoning or allergic reactions by cross-referencing the responsible substance with six circumstances that specify whether the substance-related condition was accidental, intentional self-harm, assault, undetermined, adverse effect, or the result of underdosing.
This four-part index encompasses the Index of Diseases and Injury, the Index of External Causes of Injury, the Table of Neoplasms, and the Table of Drugs and Chemicals, all of which are designed to streamline the process of locating the necessary diagnosis codes and ICD-10 coding instructions.
Sections II – IV Conventions outline rules and principles for the selection of primary diagnoses, reporting additional diagnoses, and diagnostic coding and report ing of outpatient services.
In this instance, the letter “S” designates that the diagnosis relates to “Injuries, poisoning and certain other consequences of external causes related to single body regions.”
Codes in the ICD-10-CM code set can have anywhere from three to seven characters. The more characters there are, the more specific the diagnosis. The first character is always alpha (i.e., a letter), but characters two through seven can be either alpha or numeric. Let’s take a look at an example.
You will find these codes in Chapter 20: External cause codes. These are secondary codes , which means they further describe the cause of an injury or health condition by capturing how it happened (cause), the intent (intentional or accidental), the place the event occurred, the activity the patient was engaged in at the time of the event, and the person’s status (e.g., civilian or military). You can assign as many external cause codes as necessary to explain the patient’s condition to the fullest extent possible.
So, in this example, you would submit a grand total of four ICD-10 codes to accurately describe that the patient presented with a right Achilles tendon sprain—an injury the patient suffered while recreationally running on a treadmill at a gym.
D – Subsequent encounter. This describes any encounter after the active phase of treatment, when the patient is receiving routine care for the injury during the period of healing or recovery. (This generally includes rehabilitation therapy.) In the example above, let’s assume a physician referred the patient to a physical therapist for rehabilitation of the patient’s strained Achilles tendon. Rehab therapy would be considered part of the healing and recovery phase, so you would code for “subsequent encounter,” thus assigning the seventh character “D.”
In some scenarios, you may need to record multiple codes for a single condition. Notes in the Tabular List indicate whether you’re required to report more than one code. These notes use verbiage like “Use additional code” or “Code first.” (“Code first” indicates you should code the underlying condition first.) Remember that ICD-10 also includes several combination codes, which are single codes used to classify two or more conditions that often occur together.
See? When taken apart and examined piece by piece, the ICD-10 coding structure isn’t all that scary. That said, we understand if you still have questions. Feel free to drop them below, and we’ll do our best to help you out.
International Classification of Diseases, 10th Revision (ICD-10) and Other Coding Revisions to National Coverage Determination (NCDs)--January 2022
All Centers for Medicare & Medicaid Services (CMS) ICD-10 system changes have been phased-in and are scheduled for completion by October 1, 2014, giving a full year for additional testing, fine-tuning, and preparation prior to full implementation of ICD-10 CM/PCS for all Health Insurance Portability and Accountability Act (HIPAA)-covered entities. ICD-10-CM/PCS will replace ICD-9-CM/PCS diagnosis and procedure codes in all health care settings for dates of service, or dates of discharge for inpatients, that occur on or after the implementation date of ICD-10.
The International Classification of Disease (ICD)-10 code sets provide flexibility to accommodate future health care needs, facilitating timely electronic processing of claims by reducing requests for additional information to providers. ICD-10 also includes significant improvements over ICD-9 in coding primary care encounters, external causes of injury, mental disorders, and preventive health. The ICD-10 code sets' breadth and granularity reflect advances in medicine and medical technology, as well as capture added detail on socioeconomics, ambulatory care conditions, problems related to lifestyle, and the results of screening tests.
The ICD tenth revision (ICD-10) is a code system that contains codes for diseases, signs and symptoms, abnormal findings, circumstances and external causes of diseases or injury.
ICD is used to classify diseases and store diagnostic information for clinical, quality and epidemiological purposes and also for reimbursement of insurance claims.
The International Classification of Disease (ICD) is a standard diagnostic tool created by the World Health Organization (WHO), for monitoring the incidence and prevalence of diseases and related conditions.
The ICD-10 code system offers accurate and up-to-date procedure codes to improve health care cost and ensure fair reimbursement policies. The current codes specifically help healthcare providers to identify patients in need of immediate disease management and to tailor effective disease management programs.
ICD-10 codes hold particular significance in research since code-analysis is an essential component of research and development. Code system and logic allows for fewer coding errors that ultimately benefits in the research and development analyses.
ICD-10 contains more than 14,000 codes that can be sub-classified into 16,000 codes, catering to many new diagnoses. However, there are two main classifications used worldwide:
ICD-10-CM has been adopted internationally to facilitate implementation of quality health care as well as its comparison on a global scale.
The 2022 edition of ICD-10-CM Z00.00 became effective on October 1, 2021.
Categories Z00-Z99 are provided for occasions when circumstances other than a disease, injury or external cause classifiable to categories A00 -Y89 are recorded as 'diagnoses' or 'problems'. This can arise in two main ways:
ICD-10-CM/PCS code sets will enhance the quality of data for: 1 Tracking public health conditions (complications, anatomical location) 2 Improved data for epidemiological research (severity of illness, co-morbidities) 3 Measuring outcomes and care provided to patients 4 Making clinical decisions 5 Identifying fraud and abuse 6 Designing payment systems/processing claims
The transition to ICD-10-CM/PCS code sets will take effect on October 1, 2015 and all users will transition to the new code sets on the same date.
Pregnancy trimester is designated for ICD-10-CM codes in the pregnancy, delivery and puerperium chapter.
A secondary user of ICD-9-CM codes is someone who uses already coded data from hospitals, health care providers, or health plans to conduct surveillance and/or research activities. Public health is largely a secondary user of coded data.
There are nearly 5 times as many diagnosis codes in ICD-10-CM than in ICD-9-CM
There are new concepts that did not exist in ICD-9-CM, such as under dosing, blood type, the Glasgow Coma Scale, and alcohol level.
The greater level of detail in the new code sets includes laterality, severity, and complexity of disease conditions, which will enable more precise identification and tracking of specific conditions.
The ICD-10-PCS Definitions contain the official definitions of ICD-10-PCS values in characters 3 through 7 of the seven-character procedure code, and may also provide additional explanation or examples. The definitions are arranged in section order, and designate the section and the character within the section being defined.
The Medical and Surgical section codes represent the vast majority of procedures reported in an inpatient setting. Medical and surgical procedure codes have a first character value of "0". The 2nd character indicates the general body system (e.g., gastrointestinal). The first through fifth characters are always assigned a specific value, ...
Extracorporeal assistance and performance procedure codes have a first character value of “5”. The second character value for body system is physiological systems.
Osteopathic procedure codes have a first character value of “7”. The body system character contains the value anatomical regions. There is only one root operation in the osteopathic section.
Administration section codes represent procedures for putting in or on a therapeutic, prophylactic, protective, diagnostic, nutritional or physiological substance. Administration procedure codes have a first character value of “3”. The body system character contains three values: circulatory system, indwelling device, and physiological systems and anatomical regions. The circulatory body system is used for transfusion procedures.
Measurement and monitoring procedure codes have a first character value of “4”. The second character value for body system is either physiological systems or physiological devices.
Obstetrics procedure codes have a first character value of “1”. The second character value for body system is Pregnancy. The root operations Change, Drainage, Extraction, Insertion, Inspection, Removal, Repair, Reposition, Resection and Transplantation are used in the obstetrics section, and have the same meaning as in the medical and surgical section.
