ICD-10 Interactive allows you to search the ICD-10-CM code set. ICD-10-CM diagnosis codes are comprised of codes with 3, 4, 5, 6, or 7 characters. Codes with three characters represent a category that may be further subdivided by the use of fourth and/or fifth characters and/or sixth characters, which provider greater detail. The appropriate code or codes from A00.0 through T88.9, Z00-Z99.8 must be used to identify diagnoses, symptoms, conditions, problems, complaints or other reason(s) for the encounter/visit.
When searching ICD-10-CM, codes consist of both letters and numbers (ex. M1a.339). You can search the Tabular details pages by code, trunctated code and/or keyword or phrase. Results are displayed in relevancy order. Remember: While a code title may not contain the conditions you are searching for, there may be an "Includes" note that's a part of the code result you see displayed where the term you've searched for is present. Includes notes further define, or give examples of, what's assumed within the codes' intent. Therefore, ICD-10 Interactive searches those too to ensure you don't overlook a potentially appropriate code.
ICD-10-CM retains an Alphabetic Index, that works in a similar manner to ICD-9-CM's index. Use keywords from the medical record to look up conditions, injuries and/or signs/symptoms to locate links to potential diagnoses within the Tabular code details. A separate section of the Alphabetical Index classifies environmental events, circumstances, and conditions as the cause of injury, poisoning and other adverse effects. This Index to External Causes is organized by keywords/terms, again linking to potential codes within the Tabular code details.
Certain conditions are referenced using tables. ICD-10-CM's Neoplasm Table is almost exactly the same as the ICD-9 Neoplasm Table. The Table of Drugs and Chemicals in ICD-10-CM contains classification of drugs and other chemical substances associated with poisonings and external causes of adverse effects. In ICD-10, the rows identify the substance and columns define the intent. There is NO Hypertension Table in ICD-10-CM.
