Chronic fatigue, unspecified

This code represents persistent or recurrent fatigue that significantly impacts daily functioning and has lasted for an extended period, typically six months or longer, without a clear underlying medical cause identified. It signifies a general, non-specific chronic fatigue state where a more definitive diagnosis has not been established.

Use this code when documentation indicates chronic fatigue that is not specifically diagnosed as chronic fatigue syndrome, myalgic encephalomyelitis, or other post-infection/postviral fatigue syndromes. This code is appropriate when the provider has ruled out other specific causes of fatigue but has not yet arrived at a more precise diagnosis for the chronic fatigue.

• Ensure documentation explicitly states "chronic fatigue, unspecified" or similar language indicating prolonged fatigue without a specific etiology.
• Review the "Excludes1" notes carefully to avoid miscoding; this code should never be used with G93.31, G93.32, or G93.39.
• Prioritize more specific codes for fatigue if the documentation supports a definitive diagnosis (e.g., fatigue due to anemia, hypothyroidism).
