Updated ICD9 Codes for Persante

CODE	NAME	DESCRIPTION
327.00	Organic Insomnia	Disorders characterized by impairment of the ability to initiate or maintain sleep. This may occur as a primary disorder or in association with another medical or psychiatric condition.
327.10	Organic Hypersomnia, unspecified	Disorders characterized by hypersomnolence during normal waking hours that may impair cognitive functioning.
327.13	Recurrent Hypersomnia	Disorders characterized by hypersomnolence during normal waking hours that may impair cognitive functioning. Subtypes include primary hypersomnia disorders (e.g., IDIOPATHIC HYPERSOMNOLENCE; NARCOLEPSY; and KLEINE-LEVIN SYNDROME) and secondary hypersomnia disorders where excessive somnolence can be attributed to a known cause
327.20	Organic Sleep Apnea, unspecified	Disorders characterized by multiple cessations of respirations during sleep that induce partial arousals and interfere with the maintenance of sleep
327.21	Central Sleep Apnea	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. This condition may be idiopathic (primary) or associated with lower brain stem lesions; chronic obstructive pulmonary disease (LUNG DISEASES, OBSTRUCTIVE); HEART FAILURE, CONGESTIVE; medication effect; and other conditions. Sleep maintenance is impaired, resulting in daytime hypersomnolence.
327.23	Obstructive Sleep Apnea (Adult)(Pediatric)	A disorder characterized by recurrent apneas during sleep despite persistent respiratory efforts. It is due to upper airway obstruction. The respiratory pauses may induce HYPERCAPNIA or HYPOXIA. Cardiac ARRHYTHMIA and elevation of systemic and pulmonary arterial pressures may occur. Frequent partial arousals occur throughout sleep, resulting in relative SLEEP DEPRIVATION and daytime tiredness.
327.26	Sleep Related Hypoventilation/ hypoxemia in conditions classifiable elsewhere	Clinical manifestation of respiratory distress consisting of relative deficiency of oxygen in arterial blood.
327.27	Central Sleep Apnea in conditions classified elsewhere	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. This condition may be idiopathic (primary) or associated with lower brain stem lesions; chronic obstructive pulmonary disease (LUNG DISEASES, OBSTRUCTIVE); HEART FAILURE, CONGESTIVE; medication effect; and other conditions. Sleep maintenance is impaired, resulting in daytime hypersomnolence.
327.3	Circadian Rhythm Sleep Disorder	Disorder affecting the timing of sleep. Characterized by inability to sleep at times required for normal daily activities and social needs.
327.40	Organic Parasomnia, unspecified	Category of sleep disorders characterized by abnormal and unnatural movements, behaviors, emotions, perceptions, and dreams that occur while falling asleep, sleeping, between sleep stages, or during arousals from sleep.
327.42	REM Behavior Disorder	A disorder characterized by episodes of vigorous and often violent motor activity during REM sleep (SLEEP, REM). The affected individual may inflict self injury or harm others, and is difficult to awaken from this condition. Episodes are usually followed by a vivid recollection of a dream that is consistent with the aggressive behavior.
327.43	Recurrent Isolated Sleep Paralysis	A common condition characterized by transient partial or total paralysis of skeletal muscles and areflexia that occurs upon awakening from sleep or less often while falling asleep. Stimuli such as touch or sound may terminate the episode, which usually has a duration of seconds to minutes. This condition may occur in normal subjects or be associated with NARCOLEPSY; CATAPLEXY; and hyponagogic HALLUCINATIONS. The pathophysiology of this condition is closely related to the normal hypotonia that occur during REM sleep.
327.51	Periodic Limb Movement Disorder	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.
327.52	Sleep related Leg Cramps	Parasomnias characterized by behavioral abnormalities that occur during the transition between wakefulness and sleep (or between sleep and wakefulness).
327.53	Sleep Related Bruxism	A sleep disorder characterized by grinding and clenching of the teeth and forceful lateral or protrusive jaw movements. Sleep bruxism may be associated with TOOTH INJURIES; TEMPOROMANDIBULAR JOINT DISORDERS; sleep disturbances; and other conditions.
333.94	Restless Legs Syndrome	Neurological disorder characterized by unpleasant sensations of the legs and an urge to move them for relief; usually occurs during or just prior to sleep, causing difficulty falling asleep or staying asleep.
345.9	Epilepsy, unspecified	A disorder characterized by recurrent episodes of paroxysmal brain dysfunction due to a sudden, disorderly, and excessive neuronal discharge. Epilepsy classification systems are generally based upon: (1) clinical features of the seizure episodes (e.g., motor seizure), (2) etiology (e.g., post-traumatic), (3) anatomic site of seizure origin (e.g., frontal lobe seizure), (4) tendency to spread to other structures in the brain, and (5) temporal patterns (e.g., nocturnal epilepsy).
347.00	Narcolepsy w/o Cataplexy	Chronic neurologic disorder caused by the brains inability to regulate sleep – wake cycles normally. Characterized by disturbed nocturnal sleep and abnormal daytime sleep pattern.
347.01	Narcolepsy w/ Cataplexy	A condition characterized by recurrent episodes of daytime somnolence and lapses in consciousness (microsomnias) that may be associated with automatic behaviors and AMNESIA. CATAPLEXY; SLEEP PARALYSIS, and hypnagogic HALLUCINATIONS frequently accompany narcolepsy. The pathophysiology of this disorder includes sleep-onset rapid eye movement (REM) sleep, which normally follows stage III or IV sleep.
278.01	Morbid Obesity	The condition of weighing two, three, or more times the ideal weight, so called because it is associated with many serious and life-threatening disorders. BMI > 40%
278.03	Obesity hypoventilation Syndrome	Otherwise known as Pickwickian Syndrome. Condition in which severely overweight patients fail to breath rapidly or deeply enough resulting in low blood oxygen levels and high carbon dioxide levels.
307.41	Transient disorder of initiating or maintaining sleep	Disorders characterized by impairment of the ability to initiate or maintain sleep. This may occur as a primary disorder or in association with another medical or psychiatric condition.
307.45	Circadian Rhythm Sleep Disorder of Nonorganic orgin	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.
307.46	Sleep Arousal Disorder	Sleep disorders characterized by impaired arousal from the deeper stages of sleep (generally stage III or IV sleep).
333.2	Myoclonus	Brief, involuntary twitching of a muscle or group of muscles. Caused by sudden muscles contractions. Most common time patients experience myoclonus is while falling asleep.

518.83	Chronic Respiratory Failure	Failure to adequately provide oxygen to cells of the body and to remove excess carbon dioxide from them.
780.51	Insomnia with Sleep Apnea, unspecified	Disorders characterized by impairment of the ability to initiate or maintain sleep. This may occur as a primary disorder or in association with another medical (sleep apnea) or psychiatric condition.
780.52	Insomnia, unspecified	Inability to fall asleep or stay asleep as long as desired. Signs and symptoms are usually indicative of an underlying medical condition or phychiatric disorder.
780.53	Hypersomnia with Sleep Apnea, unspecified	Hypersomnia refers to a large group of disorders characterized by excessive daytime somnolence. There are many etiologies but are usually indicative of central/ brain orgin or can be secondary to another medical condition. If the orgin is unknown, it is classified as Idiopathic Hypersomnia.
780.54	Hypersomnia, unspecified	Disorders characterized by hypersomnolence during normal waking hours that may impair cognitive functioning. Subtypes include primary hypersomnia disorders (e.g., IDIOPATHIC HYPERSOMNOLENCE; NARCOLEPSY; and KLEINE-LEVIN SYNDROME) and secondary hypersomnia disorders where excessive somnolence can be attributed to a known cause (e.g., drug affect, MENTAL DISORDERS, and SLEEP APNEA SYNDROME).
780.57	Unspecified Sleep Apnea	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 APENA, CENTRAL), obstructive (see SLEEP APNEA, OBSTRUCTIVE), and mixed central-obstructive types.
786.04	Cheyne Stokes Respiration	An abnormal pattern of breathing characterized by alternating periods of apnea and deep, rapid breathing. The cycle begins with slow, shallow breaths that gradually increase in depth and rate and is then followed by a period of apnea. The period of apnea can last 5 to 30 seconds, then the cycle repeats every 45 seconds to 3 minutes.
786.09	Snoring	Rough, noisy breathing during sleep, due to vibration of the uvula and soft palate. Not a primary diagnosis. Respiratory distress not classified elsewhere.
