Type 2 Excludes
Type 2 Excludes Help
A type 2 excludes note represents "not included here". A type 2 excludes note indicates that the condition excluded is not part of the condition it is excluded from but a patient may have both conditions at the same time. When a type 2 excludes note appears under a code it is acceptable to use both the code (G47) and the excluded code together.

Clinical Information
  • A change from the patient's baseline sleeping pattern, either an increase or a decrease in the number of hours slept. This can also refer to alterations in the stages of sleep.
  • A disturbance of normal sleep patterns. There are a number of sleep disorders that range from trouble falling asleep, to nightmares, sleepwalking, and sleep apnea (problems with breathing that cause loud snoring). Poor sleep may also be caused by diseases such as heart disease, lung disease, or nerve disorders.
  • Conditions characterized by disturbances of usual sleep patterns or behaviors. Sleep disorders may be divided into three major categories: dyssomnias (i.e. Disorders characterized by insomnia or hypersomnia), parasomnias (abnormal sleep behaviors), and sleep disorders secondary to medical or psychiatric disorders. (from thorpy, sleep disorders medicine, 1994, p187)
  • Conditions characterized by disturbances of usual sleep patterns or behaviors; divided into three major categories: dyssomnias (i.e. Disorders characterized by insomnia or hypersomnia), parasomnias (abnormal sleep behaviors), and sleep disorders secondary to medical or psychiatric disorders.
  • Is it hard for you to fall asleep or stay asleep through the night? do you wake up feeling tired or feel very sleepy during the day, even if you have had enough sleep? you might have a sleep disorder. The most common kinds are
    • insomnia - a hard time falling or staying asleep
    • sleep apnea - breathing interruptions during sleep
    • restless legs syndrome - a tingling or prickly sensation in the legs
    • narcolepsy - daytime "sleep attacks"
    nightmares, night terrors, sleepwalking, sleep talking, head banging, wetting the bed and grinding your teeth are kinds of sleep problems called parasomnias. There are treatments for most sleep disorders. Sometimes just having regular sleep habits can help.
