Answer: False
The ICD-10-cm and alphabetic index must be both used to assign a code. Although,
the ICD-10-CM provides very detailed and specific documentation, the coder
needs to verify, review and justify the selection of codes in the alphabetic
index.
Therefore, it is essential to use both
the Alphabetic
Index and Tabular List when
locating and assigning a code because the Alphabetic Index does not always
provide the full code.
