References found for the code G43 in the Index of Diseases and Injuries:
- Type 1 Excludes Notes: Type 1 Excludes Notes
A type 1 Excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- headache NOS (R51)
- lower half migraine (G44.00)
- Type 2 Excludes Notes: Type 2 Excludes Notes
A type 2 Excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
- headache syndromes (G44.-)
- the following terms are to be considered equivalent to intractable: pharmacoresistant (pharmacologically resistant), treatment resistant, refractory (medically) and poorly controlled
Information for Patients
If you suffer from migraine headaches, you're not alone. About 12 percent of the U.S. population gets them. Migraines are recurring attacks of moderate to severe pain. The pain is throbbing or pulsing, and is often on one side of the head. During migraines, people are very sensitive to light and sound. They may also become nauseated and vomit.
Migraine is three times more common in women than in men. Some people can tell when they are about to have a migraine because they see flashing lights or zigzag lines or they temporarily lose their vision.
Many things can trigger a migraine. These include
- Lack of food or sleep
- Exposure to light
- Hormonal changes (in women)
Doctors used to believe migraines were linked to the opening and narrowing of blood vessels in the head. Now they believe the cause is related to genes that control the activity of some brain cells. Medicines can help prevent migraine attacks or help relieve symptoms of attacks when they happen. For many people, treatments to relieve stress can also help.
