From the Research

The ICD-10 code for acute night sweats is R61, which represents "Generalized hyperhidrosis" or excessive sweating. Night sweats are classified under this code as they represent episodes of excessive sweating that occur during sleep. When documenting this symptom, it's essential to note that if the night sweats are due to an underlying condition such as infection, malignancy, or hormonal disorder, you should code for the primary condition first, with R61 as a secondary code 1.

Causes of Night Sweats

Night sweats can be caused by various factors including:

  • Infections (like tuberculosis or HIV)
  • Certain medications
  • Hormonal changes (such as menopause)
  • Lymphoma, or other cancers
  • Menopause, mood disorders, gastroesophageal reflux disease, hyperthyroidism, and obesity 1

Evaluation and Treatment

When evaluating a patient with night sweats, it's crucial to look for associated symptoms like fever, weight loss, or fatigue that might help identify the underlying cause. Treatment is directed at addressing the primary condition rather than just the symptom of night sweats itself. A systematic and cost-conscious strategy that uses readily available laboratory and imaging studies may be employed to diagnose the underlying cause of night sweats 1.

Diagnosis and Management

The management of secondary hyperhidrosis involves the treatment of the underlying cause. For primary hyperhidrosis, treatment depends on its severity and the sites affected 2. A variety of treatment modalities currently exist to manage hyperhidrosis, including lifestyle and behavioral recommendations, antiperspirants, iontophoresis, botulinum toxin injections, oral systemic agents, and energy-delivering devices 3.

Quality of Life

Hyperhidrosis is a chronic disorder of excess sweat production that may have a significant adverse effect on quality of life 3. Patients experience reduced quality of life and face significantly impairment in social interactions and occupational activities 4. Therefore, it's essential to address the underlying cause of night sweats and manage the symptom to improve the patient's quality of life.
