the International Classification of Sleep Disorders (ICSD), an advanced system cultured by the American Academy of Sleep Medicine (AASM) for sleep specialists. The ICD and DSM lump different disorders together, while the ICSD tends to split related disorders into multiple discrete categories.
ICD-9-CM: 27.6, 27.7, 29 ... UPPP is the most commonly performed procedure for obstructive sleep apnea with approximately 33,000 procedures performed per year.
During the late 1990s and the 2000s, researchers (including Finkelstein, [4] Schmidt, Larrosa [5] and others) published data which questioned the efficiency of the treatment and demonstrated that in a considerable number of cases, laser-assisted uvulopalatoplasty may also cause mild obstructive sleep apnea in patients who has been nonapneic ...
Sleep apnea is measured by the apnea-hypopnea index (AHI). An AHI is determined with a sleep study. AHI values for adults are categorized as: [2] [3] Normal: AHI<5; Mild sleep apnea: 5≤AHI<15; Moderate sleep apnea: 15≤AHI<30; Severe sleep apnea: AHI≥30; An episode is when a person hesitates to breathe or stops their breathing altogether.
An "event" can be either an apnea, characterized by complete cessation of airflow for at least 10 seconds, or a hypopnea in which airflow decreases by 50 percent for 10 seconds or decreases by 30 percent if there is an associated decrease in the oxygen saturation or an arousal from sleep. [43]
DSM (see below) changes some of its coding to correspond to the codes in ICD. In 2005, for example, DSM changed the diagnostic codes for circadian rhythm sleep disorders from the 307-group to the 327-group; the new codes reflect the moving of these disorders from the Mental Disorders section to the Neurological section in the ICD [3]
This is a shortened version of the sixteenth chapter of the ICD-9: Symptoms, Signs and Ill-defined Conditions. It covers ICD codes 780 to 799. The full chapter can be found on pages 455 to 471 of Volume 1, which contains all (sub)categories of the ICD-9. Volume 2 is an alphabetical index of Volume 1.
