What does ICD 9 stand for?
ICD-9 stands for International Classification of Disease, Ninth Revision. Coding is a universal or standard system used for the purpose of identifying diseases.

What is ICD 9 coding used for?
The ICD-9 was used to code and classify mortality data from death certificates until 1999, when use of ICD-10 for mortality coding started. a tabular list containing a numerical list of the disease code numbers in tabular form; a classification system for surgical, diagnostic, and therapeutic procedures (alphabetic index and tabular list).
What is the ICD 9 code for unknown diagnosis?
Unspecified diagnosis codes like U09.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition.

What are ICD-9 diagnosis codes?
ICD-9-CM is the official system of assigning codes to diagnoses and procedures associated with hospital utilization in the United States. The ICD-9 was used to code and classify mortality data from death certificates until 1999, when use of ICD-10 for mortality coding started.
What is an example of an ICD-9 code?
For example, ICD-9 provides a fifth-digit subclassification for use with the diagnostic category for migraine (346) and instructs users to extend the four-digit codes for classical migraine (346.0), common migraine (346.1), etc., to five digits.
What are ICD-9 CPT codes?
The ICD-9-CM codes are for the disorder or disorders you are treating while the CPT codes are for reporting the procedure or procedures you performed. The ICD-9-CM is coordinated and maintained by the federal government while the AMA maintains and updates the CPT codes.
What is the ICD-9 code set?
The International Classification of Diseases, Clinical Modification (ICD-9-CM) is an adaption of the ICD code set created by the U.S. National Center for Health Statistics (NCHS) and used in assigning diagnostic and procedure codes in the United States.
What is the difference between ICD-9 and ICD-10 codes?
ICD-9 uses mostly numeric codes with only occasional E and V alphanumeric codes. Plus, only three-, four- and five-digit codes are valid. ICD-10 uses entirely alphanumeric codes and has valid codes of up to seven digits.
Who still uses ICD-9 codes?
Currently, the U.S. is the only industrialized nation still utilizing ICD-9-CM codes for morbidity data, though we have already transitioned to ICD-10 for mortality.
What is the difference between ICD codes and CPT codes?
CPT codes refer to the treatment being given, while ICD codes refer to the problem that the treatment is aiming to resolve. The two work hand-in-hand to quickly provide payors specific information about what service was performed (the CPT code) and why (the ICD code).
How do you read ICD-9 codes?
The format for ICD-9 diagnoses codes is a decimal placed after the first three characters and two possible add-on characters following: xxx. xx. ICD-9 PCS were used to report procedures for inpatient hospital services from Volume 3, which represent procedures that were done at inpatient hospital facilities.
What are ICD 10 codes used for?
The ICD-10-CM (International Classification of Diseases, Tenth Revision, Clinical Modification) is a system used by physicians and other healthcare providers to classify and code all diagnoses, symptoms and procedures recorded in conjunction with hospital care in the United States.
When did ICD-9 codes start?
ICD-8 went into effect beginning in 1968. One year later, WHO advised a series of ICD-9 specifications. Several years later in 1975, ICD-9 was published with its implementation becoming formalized in 1979.

Is ICD-9-CM still in use?
ICD-9 is out of date. ICD-9 is more than 35 years old and contains outdated, obsolete terms that are inconsistent with current medical practice. The structure of ICD-9 limits the number of new codes that can be created, and many ICD-9 categories are full.
When did we stop using ICD-9 codes?
No updates have been made to ICD-9 since October 1, 2013, as the code set is no longer being maintained.
What is the ICd 9 classification?
The current diagnosiscoding system used in the United States is International Classification of Diseases (ICD)-9-Clinical Modification (CM), which has an alphabetic index (Volume 2) and a tabular index (Volume 1). The ICD-9-CM system is used in all venues of healthcare to report diagnoses. ICD-9-CM is based on the official version of the World Health Organization's 9th Revision of the International Classification of Diseases (ICD-9). In 1977, a steering committee was formed by the National Center for Health Statistics (NCHS) to clinically modify ICD-9 for use in the United States. The term “Clinical” meant that the United States needed a useful tool to report diagnoses, to classify morbidity data for indexing, for medical care review, and to capture basic health statistics for all venues of healthcare.
How many ICD-9 codes are there?
The current ICD-9-CM system consists of ∼13,000 codes and is running out of numbers. The new ICD-10-CM system is expanding to ∼68,000 codes and has flexibility for expansion. The ICD-9-CM codes have three to five characters, which are numeric with the exceptions of the V codes (factors influencing healthcare), E Codes (external causes of injury), and M Codes (neoplasm morphology) that begin with a single letter. The new ICD-10-CM codes have three to seven characters that are alphanumeric. Physicians created the ICD-10-CM terminology, whereas ICD-9-CM used the coding terminology. See Table 1for a comparison of the two coding systems.
Why is the ICd 9 CM different from the ICd 10 CM?
There are numerous reasons that the United States needs to change from ICD-9-CM to the ICD-10-CM system. The current ICD-9-CM coding system lacks specificity and detail. If the reader has attempted data extraction utilizing the ICD-9-CM system, you have probably encountered difficulty obtaining the exact diagnosis for which you were searching. For many research purposes, the ICD-9-CM diagnosis codes can be very broad, and lack the specificity to narrow the search.
What are the benefits of ICD-10 classification?
One of the main benefits is that the disease classifications will be consistent with current clinical practice and medical technology advances. The new classification codes will be very granular, which means the level of specificity will greatly improve. Numerous new codes will represent more specific anatomic sites, etiologies, comorbidities, and complications, and will improve the ability to demonstrate severity of illness. For instance, the new feature of laterality is directly built into the new codes: separate codes will distinguish right, left, and bilateral, where needed. The increased granularity will provide better analysis of disease patterns and outbreak of disease. Additionally, the United States will finally be using the same diagnosis coding system as the rest of the world. This article will describe what the ICD-9-CM/ICD-10-CM codes are, why they are so important, and how clinicians and researchers will convert from ICD-9-CM to ICD-10-CM effective October 1, 2014.

Why is ICD-9-CM running out of code?
ICD-9-CM is running out of code capacity to expand and keep up with advances in technology. Most of the categories contained in ICD-9-CM are completely full with no room for expansion. Another reason for the switch is the growing need for precise quality data. As many of you are already aware, payment systems are requiring quality measure collection for all venues of healthcare.
When was the ICD-10 code developed?
In 1994, the NCHS began evaluating whether the existing ICD-10 developed by the World Health Organization (WHO) needed to be modified for use in the United States. ICD-10 was adopted by the WHO in 1990, with modifications made by Australia in 1998, and Canada in 2001. The ICD-10 is copyrighted by the WHO, which owns and publishes the classification. The WHO has authorized the development of an adaptation of ICD-10 for use in the United States for U.S. government purposes. The United States is the only industrialized nation that has not implemented ICD-10 for morbidity. The United States has used ICD-10-CM to code mortality since 1999. Since 1994, the NCHS has been developing the clinical modifications for use in the United States. The final rule for the Health Insurance Portability and Accountability Act (HIPAA) Administrative Simplification to Medical Data Code Set Standards to adopt ICD-10-CM was published on January 16, 2009.1The mandatory compliance date is October 1, 2014. Draft code sets and guidelines have been released in 2002, 2007, 2009, 2010, 2011, 2012, and the current version for 2013.
