User can convert ICD-9 codes to their ICD-10 equivalents by using the conversion tools on websites such as ICD10Data.com, ICD10CMCode.com and AAPC.com. The conversion tools on these websites are also capable of converting ICD-10 codes to the ICD-9 version by selecting the appropriate conversion option.
ICD10CMCode.com and AAPC.com require users to select a conversion option by clicking on it or selecting it from a drop-down menu before typing in the code. Unlike the other two, ICD10Data.com automatically detects the type of code and provides an appropriate conversion. After the conversion process is complete, these websites display the new code and a short description of the diagnosis that the code designates. These online conversion tools cannot convert ICD-9-PCS and ICD-10-PCS codes.
