Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • Fatigue NOS
  • Lack of energy
  • Lethargy
  • Tiredness

Type 2 Excludes

Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
  • exhaustion and fatigue due to depressive episode F32

Clinical Information

  • COMPASSION FATIGUE-. emotional distress caused by repeated or prolonged expression of compassion or empathy. it may occur in individuals working in care giving professions.
  • ASTHENOPIA-. term generally used to describe complaints related to refractive error ocular muscle imbalance including pain or aching around the eyes burning and itchiness of the eyelids ocular fatigue and headaches.
  • AUDITORY FATIGUE-. loss of sensitivity to sounds as a result of auditory stimulation manifesting as a temporary shift in auditory threshold. the temporary threshold shift tts is expressed in decibels.
  • FATIGUE-. the state of weariness following a period of exertion mental or physical characterized by a decreased capacity for work and reduced efficiency to respond to stimuli.
  • MENTAL FATIGUE-. a condition of low alertness or cognitive impairment usually associated with prolonged mental activities or stress.
  • VOICE DISORDERS-. pathological processes that affect voice production usually involving vocal cords and the laryngeal mucosa. voice disorders can be caused by organic anatomical or functional emotional or psychological factors leading to dysphonia; aphonia; and defects in voice quality loudness and pitch.
  • FATIGUE SYNDROME CHRONIC-. a syndrome characterized by persistent or recurrent fatigue diffuse musculoskeletal pain sleep disturbances and subjective cognitive impairment of 6 months duration or longer. symptoms are not caused by ongoing exertion; are not relieved by rest; and result in a substantial reduction of previous levels of occupational educational social or personal activities. minor alterations of immune neuroendocrine and autonomic function may be associated with this syndrome. there is also considerable overlap between this condition and fibromyalgia. from semin neurol 1998;182:237 42; ann intern med 1994 dec 15;12112: 953 9
  • FRACTURES STRESS-. fractures due to the strain caused by repetitive exercise. they are thought to arise from a combination of muscle fatigue and bone failure and occur in situations where bone remodeling predominates over repair. the most common sites of stress fractures are the metatarsus; fibula; tibia; and femoral neck.
  • MUSCLE FATIGUE-. a state arrived at through prolonged and strong contraction of a muscle. studies in athletes during prolonged submaximal exercise have shown that muscle fatigue increases in almost direct proportion to the rate of muscle glycogen depletion. muscle fatigue in short term maximal exercise is associated with oxygen lack and an increased level of blood and muscle lactic acid and an accompanying increase in hydrogen ion concentration in the exercised muscle.

Diagnostic Related Groups

The ICD-10 code R53.83 is grouped in the following groups for version MS-DRG V37.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC).

Information for Patients


Everyone feels tired now and then. Sometimes you may just want to stay in bed. But, after a good night's sleep, most people feel refreshed and ready to face a new day. If you continue to feel tired for weeks, it's time to see your doctor. He or she may be able to help you find out what's causing your fatigue and recommend ways to relieve it.

Fatigue itself is not a disease. Medical problems, treatments, and personal habits can add to fatigue. These include

  • Taking certain medicines, such as antidepressants, antihistamines, and medicines for nausea and pain
  • Having medical treatments, like chemotherapy and radiation
  • Recovering from major surgery
  • Anxiety, stress, or depression
  • Staying up too late
  • Drinking too much alcohol or too many caffeinated drinks
  • Pregnancy

One disorder that causes extreme fatigue is chronic fatigue syndrome (CFS). This fatigue is not the kind of tired feeling that goes away after you rest. Instead, it lasts a long time and limits your ability to do ordinary daily activities.
