Everyday life is a roller coaster of emotions and changes in mood can
interfere with everyday life. People, in most cases may experience
normal fluctuations in mood that may come and go. When your mood
starts to have a serious impact on your daily activities and your social,
educational and professional relationships, people may experience
mood disorder. Regarded as a serious mental health problem, a mood
disorder primarily affects a person’s emotional state wherein
theperson’s mood become s distorted or incompatible with their
circumstances and interferes with their normal ability to function. This
is a disorder in which a person experiences long periods of extreme
happiness, extreme sadness, or both. Reports suggest that around
20.9 million American adults aged 18 and older have a mood disorder.
It is estimated that females are more likely to be diagnosed with mood
disorder than men. In fact, 45 percent of those with a mood disorder
will face severe impairment. With appropriate diagnosis, treatment,
and support, most people struggling with mood disorders will get
better. Therapy, antidepressants, and support and self-care can help
treat mood disorders. Psychiatry medical billing and coding can be
a challenging task. Psychiatrists, clinical psychologists or other
specialists who treat various types of mood disorders need to correctly
document the same in patient medical records. Bi lling and coding
services from a reputable medical billing company can help simplify
the documentation process.
Many factors contribute to mood disorders. In most cases, they are
caused by an imbalance of brain chemicals. On the other hand, major
life events (such as stressful life changes) may also contribute to a
depressed mood. These life events (losing a job, getting divorced,
losing a loved one, death in the family, and financial trouble) coupled

mood disorder difficult to manage. Common risk factors associated

mood disorder, trauma, stress or major life changes in the case of
depression, physical illness or use of certain medications and changes
