Other amnesia

This code signifies a memory impairment characterized by the inability to recall past events or learn new information, without a clear underlying physiological cause or substance use. It encompasses various forms of amnesia that do not fit more specific diagnostic criteria.

This code is appropriate when documentation indicates amnesia that is not attributable to a specific neurological condition, head trauma, or psychoactive substance. It is used for cases where the etiology of the memory loss is unknown or not clearly defined as organic.

• Carefully review documentation to rule out specific organic causes (e.g., F04, F06.8) or substance-induced amnesia (F10-F19 with .6).
• Do not use this code for transient global amnesia (G45.4), which has a distinct code.
• Ensure the physician's notes clearly state "amnesia, unspecified" or "other amnesia" when a more specific diagnosis cannot be determined.
