Valid for Submission
G47.9 is a billable diagnosis code used to specify a medical diagnosis of sleep disorder, unspecified. The code G47.9 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
The ICD-10-CM code G47.9 might also be used to specify conditions or terms like ank3-related intellectual disability, sleep disturbance syndrome, asthma causing night waking, asthma disturbing sleep, asthma disturbs sleep frequently, asthma disturbs sleep weekly , delayed onset of sleep, etc.
Unspecified diagnosis codes like G47.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
Tabular List of Diseases and Injuries
The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code G47.9:

- Unspecified sleep-wake disorder
Index to Diseases and Injuries
The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for the code G47.9 are found in the index:

- SLEEP APNEA SYNDROMES-. disorders characterized by multiple cessations of respirations during sleep that induce partial arousals and interfere with the maintenance of sleep. sleep apnea syndromes are divided into central see sleep apnea central obstructive see sleep apnea obstructive and mixed central obstructive types.
- SLEEP WAKE DISORDERS-. abnormal sleep wake schedule or pattern associated with the circadian rhythm which affect the length timing and/or rigidity of the sleep wake cycle relative to the day night cycle.
- SLEEP DISORDERS CIRCADIAN RHYTHM-. dyssomnias associated with disruption of the normal 24 hour sleep wake cycle secondary to travel e.g. jet lag syndrome shift work or other causes.
- SLEEP APNEA CENTRAL-. a condition associated with multiple episodes of sleep apnea which are distinguished from obstructive sleep apnea sleep apnea obstructive by the complete cessation of efforts to breathe. this disorder is associated with dysfunction of central nervous system centers that regulate respiration.
- NOCTURNAL MYOCLONUS SYNDROME-. excessive periodic leg movements during sleep that cause micro arousals and interfere with the maintenance of sleep. this condition induces a state of relative sleep deprivation which manifests as excessive daytime hypersomnolence. the movements are characterized by repetitive contractions of the tibialis anterior muscle extension of the toe and intermittent flexion of the hip knee and ankle. adams et al. principles of neurology 6th ed p387
- SLEEP DISORDERS INTRINSIC-. dyssomnias i.e. insomnias or hypersomnias associated with dysfunction of internal sleep mechanisms or secondary to a sleep related medical disorder e.g. sleep apnea post traumatic sleep disorders etc.. from thorpy sleep disorders medicine 1994 p187
- DYSSOMNIAS-. a broad category of sleep disorders characterized by either hypersomnolence or insomnia. the three major subcategories include intrinsic i.e. arising from within the body sleep disorders intrinsic extrinsic secondary to environmental conditions or various pathologic conditions and disturbances of circadian rhythm. from thorpy sleep disorders medicine 1994 p187
Convert G47.9 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code G47.9 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
Information for Patients
What is sleep?
Sleep is a complex biological process. While you are sleeping, you are unconscious, but your brain and body functions are still active. They are doing a number of important jobs that help you stay healthy and function at your best. So when you don't get enough quality sleep, it does more than just make you feel tired. It can affect your physical and mental health, thinking, and daily functioning.
What are sleep disorders?
Sleep disorders are conditions that disturb your normal sleep patterns. There are more than 80 different sleep disorders. Some major types include
- Insomnia - being unable to fall asleep and stay asleep. This is the most common sleep disorder.
- Sleep apnea - a breathing disorder in which you stop breathing for 10 seconds or more during sleep
- Restless leg syndrome (RLS) - a tingling or prickly sensation in your legs, along with a powerful urge to move them
- Hypersomnia - being unable to stay awake during the day. This includes narcolepsy, which causes extreme daytime sleepiness.
- Circadian rhythm disorders - problems with the sleep-wake cycle. They make you unable to sleep and wake at the right times.
- Parasomnia - acting in unusual ways while falling asleep, sleeping, or waking from sleep, such as walking, talking, or eating
Some people who feel tired during the day have a true sleep disorder. But for others, the real problem is not allowing enough time for sleep. It's important to get enough sleep every night. The amount of sleep you need depends on several factors, including your age, lifestyle, health, and whether you have been getting enough sleep recently. Most adults need about 7-8 hours each night.
What causes sleep disorders?
There are different causes for different sleep disorders, including
- Other conditions, such as heart disease, lung disease, nerve disorders, and pain
- Mental illnesses, including depression and anxiety
Sometimes the cause is not known.
There are also some factors that can contribute to sleep problems, including
- Caffeine and alcohol
- An irregular schedule, such as working the night shift
- Aging. As people age, they often get less sleep or spend less time in the deep, restful stage of sleep. They are also more easily awakened.
What are the symptoms of sleep disorders?
The symptoms of sleep disorders depend on the specific disorder. Some signs that you may have a sleep disorder include that
- You regularly take more than 30 minutes each night to fall asleep
- You regularly wake up several times each night and then have trouble falling back to sleep, or you wake up too early in the morning
- You often feel sleepy during the day, take frequent naps, or fall asleep at the wrong times during the day
- Your bed partner says that when you sleep, you snore loudly, snort, gasp, make choking sounds, or stop breathing for short periods
- You have creeping, tingling, or crawling feelings in your legs or arms that are relieved by moving or massaging them, especially in the evening and when trying to fall asleep
- Your bed partner notices that your legs or arms jerk often during sleep
- You have vivid, dreamlike experiences while falling asleep or dozing
- You have episodes of sudden muscle weakness when you are angry or fearful, or when you laugh
- You feel as though you cannot move when you first wake up
How are sleep disorders diagnosed?
To make a diagnosis, your health care provider will use your medical history, your sleep history, and a physical exam. You may also have a sleep study (polysomnogram). The most common types of sleep studies monitor and record data about your body during a full night of sleep. The data includes
- Brain wave changes
- Eye movements
- Breathing rate
- Blood pressure
- Heart rate and electrical activity of the heart and other muscles
Other types of sleep studies may check how quickly you fall asleep during daytime naps or whether you are able to stay awake and alert during the day.
What are the treatments for sleep disorders?
Treatments for sleep disorders depend on which disorder you have. They may include
- Good sleep habits and other lifestyle changes, such as a healthy diet and exercise
- Cognitive behavioral therapy or relaxation techniques to reduce anxiety about getting enough sleep
- CPAP (continuous positive airway pressure) machine for sleep apnea
- Bright light therapy (in the morning)
- Medicines, including sleeping pills. Usually, providers recommend that you use sleeping pills for a short period of time.
- Natural products, such as melatonin. These products may help some people, but are generally for short-term use. Make sure to check with your health care provider before you take any of them.
