2006 ICD-9 Codes - 7 of 7

287.32 Evans' syndrome is a combination of idiopathic thrombocytopenia and autoimmune hemolytic anemia. Treatment includes intravenous immunoglobulin (IVIg) and steroids with or without transfusion of platelets and/or red blood cells.

287.33 Congenital and hereditary thrombocytopenic purpura
287.39 Other primary thrombocytopenia

Two new codes for "induced" sleep disorders:

291.82 Alcohol induced sleep disorders
292.85 Drug induced sleep disorders

There are numerous new codes for types of insomnia.

There is now a code for organic insomnia 327.00 versus non-organic (psychological) sleep disorder, Insomnia, ICD-9 Code 307.41.

Note that many insurance companies will not pay for psychological-based diagnoses if the provider is not a health specialist.

327.00 Organic insomnia, unspecified
327.01 Insomnia due to medical condition classified elsewhere
327.02  Insomnia due to mental disorder
327.09  Other organic insomnia
327.10  Organic hypersomnia, unspecified
327.11 Idiopathic hypersomnia with long sleep time
327.12  Idiopathic hypersomnia without long sleep time
327.13  Recurrent hypersomnia
327.14  Hypersomnia due to medical condition classified elsewhere
327.15  Hypersomnia due to mental disorder
327.19  Other organic hypersomnia

These include new codes for sleep apnea.

327.20 Organic sleep apnea, unspecified
327.21 Primary central sleep apnea
327.22 High altitude periodic breathing
327.23 Obstructive sleep apnea (adult) (pediatric)
327.24 Idiopathic sleep related non obstructive alveolar hypoventilation
327.25* Congenital central alveolar hypoventilation syndrome
327.26 Sleep related hypoventilation/hypoxemia in conditions classified elsewhere.
327.27 Central sleep apnea in conditions classified elsewhere
327.29 Other organic sleep apnea.

Sleep apnea is the cessation of breathing that occurs during sleep. Usually due to obstruction of the airway, it can also be due to inability of the brain to initiate respiration.

New ICD-9 codes for circadian rhythm sleep disorder.

Circadian rhythm is the name given to the roughly 24 hour cycles shown by physiological processes in plants and animals. (The term circadian comes from the Latin circa, meaning "around" and dies, "day", meaning literally, "around a day.") 

The circadian rhythm is neither fully dependent on nor fully independent of external cues such as sunlight and temperature. Early researchers identified that some sort of "internal" rhythm must exist, because plants and animals did not react immediately to artificially-induced changes in daily rhythms. However it has been well established that a mechanism for adjustment also exists, as plants and animals will eventually adjust their internal clock to a new pattern (if it is sufficiently regular).

327.30* Circadian rhythm sleep disorder, unspecified
327.31* Circadian rhythm sleep disorder, delayed sleep phase type
327.32* Circadian rhythm sleep disorder, advanced sleep phase type
327.33* Circadian rhythm sleep disorder, irregular sleep-wake type
327.34* Circadian rhythm sleep disorder, free-running type
327.35* Circadian rhythm sleep disorder, jet lag type
327.36* Circadian rhythm sleep disorder, shift work type
327.37* Circadian rhythm sleep disorder in conditions classified elsewhere
327.39* Other circadian rhythm sleep disorder

Delayed sleep-phase syndrome (DSPS) 327.31, is a chronic sleep disorder in which the patient's internal body clock is not in sync with the morning-rise / evening-sleep pattern of the majority of adults. A growing body of evidence suggests that the problem is genetic. DSPS patients may have a severely reduced reaction to the re-setting effect of light on the body clock.
