Code Description

ICD-10 R53.83 is a billable code used to indicate a diagnosis of other fatigue.

Key Diagnostic Point:

R53.83 is used to classify fatigue that is not specified elsewhere in the ICD-10 coding system. Fatigue is a common symptom that can be described as a state of extreme tiredness, lack of energy, or exhaustion that is not relieved by rest. It can be acute or chronic and may be associated with various underlying conditions, including infections, chronic diseases, psychological disorders, and lifestyle factors. The clinical presentation of fatigue can vary widely, with patients reporting feelings of weakness, lethargy, and decreased motivation. It is essential to evaluate the context in which fatigue occurs, as it may be a primary complaint or a secondary symptom of another condition. Laboratory findings may include anemia, thyroid dysfunction, or electrolyte imbalances, while clinical signs may involve decreased physical performance or cognitive impairment. Accurate diagnosis requires a thorough history, physical examination, and appropriate laboratory tests to rule out underlying causes.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of fatigue-related symptoms, enabling better tracking of patient outcomes and healthcare utilization. R53.83 provides a distinct classification for fatigue that does not fit into other categories, improving the granularity of data collection.

ICD-9 vs ICD-10

Frequently Asked Questions

When should I use R53.83 instead of R53.81?

Use R53.83 when the fatigue does not meet the criteria for chronic fatigue syndrome or when the underlying cause is not specified. R53.81 should be used when the patient meets the specific criteria for chronic fatigue syndrome.
