Other frontotemporal neurocognitive disorder

This code signifies a neurocognitive disorder characterized by progressive decline in behavior, personality, or language, consistent with frontotemporal lobar degeneration, but not meeting criteria for specific subtypes like behavioral variant FTD or primary progressive aphasia. It represents a broader category for frontotemporal neurocognitive disorders that are not otherwise specified or clearly defined as a distinct subtype.

Use this code when documentation indicates a diagnosis of frontotemporal neurocognitive disorder, but the specific subtype (e.g., behavioral variant, semantic dementia, nonfluent agrammatic primary progressive aphasia) is not clearly identified or does not fit established criteria. This code is appropriate when the clinician has diagnosed FTD but has not specified the exact clinical presentation or underlying pathology.

• Ensure documentation explicitly states "frontotemporal neurocognitive disorder" or "frontotemporal dementia" without further specification of a subtype.
• Avoid using this code if a more specific FTD subtype (e.g., G31.01 for behavioral variant FTD) is documented.
• Always sequence this code after any associated underlying conditions or complications, if applicable.
