2025 ICD-10-CM Diagnosis Code R54

Approximate Synonyms

The following list of clinical terms are approximate synonyms, alternative descriptions, or common phrases that might be used by patients, healthcare providers, or medical coders to describe the same condition. These synonyms and related diagnosis terms are often used when searching for an ICD-10 code, especially when the exact medical terminology is unclear. Whether you're looking for lay terms, similar diagnosis names, or common language alternatives, this list can help guide you to the correct ICD-10 classification.

Clinical Classification

Clinical Classifications group individual ICD-10-CM diagnosis codes into broader, clinically meaningful categories. These categories help simplify complex data by organizing related conditions under common clinical themes.

They are especially useful for data analysis, reporting, and clinical decision-making. Even when diagnosis codes differ, similar conditions can be grouped together based on their clinical relevance. Each category is assigned a unique CCSR code that represents a specific clinical concept, often tied to a body system or medical specialty.

Clinical Information

• Lethargy

  a general state of sluggishness, listless, or uninterested, with being tired, and having difficulty concentrating and doing simple tasks. it may be related to depression or drug addiction.

• Alert Fatigue, Health Personnel

  mental fatigue experienced by health care providers who encounter numerous alerts and reminders from the use of clinical decision support systems. as the numbers of alerts and reminders designed to provide meaningful assistance to the patient care process increases, many health personnel may ignore them.

• 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.

• Compassion Fatigue

  emotional distress caused by repeated or prolonged expression of compassion or empathy. it may occur in individuals working in care giving professions.

• Emotional Exhaustion

  a state of feeling emotionally overextended and drained.

• 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.

• 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;18(2):237-42; ann intern med 1994 dec 15;121(12): 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.

• Heat Stress Disorders

  a group of conditions that develop due to overexposure or overexertion in excessive environmental heat.

• Mental Fatigue

  a condition of low alertness or cognitive impairment, usually associated with prolonged mental activities or stress.

• 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.

• 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.

• Asthenia

  clinical sign or symptom manifested as debility, or lack or loss of strength and energy.

• Neurocirculatory Asthenia

  a clinical syndrome characterized by palpitation, shortness of breath, labored breathing, subjective complaints of effort and discomfort, all following slight physical exertion. other symptoms may be dizziness, tremulousness, sweating, and insomnia. neurocirculatory asthenia is most typically seen as a form of anxiety disorder.

• Frail Elderly

  older adults or aged individuals who are lacking in general strength and are unusually susceptible to disease or to other infirmity.

• Frailty

  a state of increased vulnerability to stressors, following declines in function and reserves across multiple physiologic systems, characterized by muscle weakness; fatigue; slowed motor performance; low physical activity; and unintentional weight loss.

• Cachexia

  general ill health, malnutrition, and weight loss, usually associated with chronic disease.

• Fibromyalgia

  a common nonarticular rheumatic syndrome characterized by myalgia and multiple points of focal muscle tenderness to palpation (trigger points). muscle pain is typically aggravated by inactivity or exposure to cold. this condition is often associated with general symptoms, such as sleep disturbances, fatigue, stiffness, headaches, and occasionally depression. there is significant overlap between fibromyalgia and the chronic fatigue syndrome (fatigue syndrome, chronic). fibromyalgia may arise as a primary or secondary disease process. it is most frequent in females aged 20 to 50 years. (from adams et al., principles of neurology, 6th ed, p1494-95)

• Fatigue, CTCAE 3.0|Fatigue (asthenia, lethargy, malaise)

  an unfavorable feeling of fatigue temporally associated with the use of a medical treatment or procedure.

  a feeling of malaise after physical or mental effort or stress.

Code Edits

The Medicare Code Editor (MCE) detects errors and inconsistencies in ICD-10-CM diagnosis coding that can affect Medicare claim validity. These Medicare code edits help medical coders and billing professionals determine when a diagnosis code is not appropriate as a principal diagnosis, does not meet coverage criteria. Use this list to verify whether a code is valid for Medicare billing and to avoid claim rejections or denials due to diagnosis coding issues.

Convert R54 to ICD-9-CM

Below are the ICD-9 codes that most closely match this ICD-10 code, based on the General Equivalence Mappings (GEMs). This ICD-10 to ICD-9 crosswalk tool is helpful for coders who need to reference legacy diagnosis codes for audits, historical claims, or approximate code comparisons.
