2026 ICD-10-CM Diagnosis Code F32.ADepression, unspecified

AHRQ’s CCSR groups this code into broader clinical categories.

• Adjustment Disorders

  maladaptive reactions to identifiable psychosocial stressors occurring within a short time after onset of the stressor. they are manifested by either impairment in social or occupational functioning or by symptoms (depression, anxiety, etc.) that are in excess of a normal and expected reaction to the stressor.

• Affective Disorders, Psychotic

  disorders in which the essential feature is a severe disturbance in mood (depression, anxiety, elation, and excitement) accompanied by psychotic symptoms such as delusions, hallucinations, gross impairment in reality testing, etc.

• Bipolar Disorder

  a major affective disorder marked by severe mood swings (manic or major depressive episodes) and a tendency to remission and recurrence.

• Cortical Spreading Depression

  the decrease in neuronal activity (related to a decrease in metabolic demand) extending from the site of cortical stimulation. it is believed to be responsible for the decrease in cerebral blood flow that accompanies the aura of migraine with aura. (campbell's psychiatric dictionary, 8th ed.)

• Depression

  depressive states usually of moderate intensity in contrast with major depressive disorder present in neurotic and psychotic disorders.

• Depression, Chemical

  the decrease in a measurable parameter of a physiological process, including cellular, microbial, and plant; immunological, cardiovascular, respiratory, reproductive, urinary, digestive, neural, musculoskeletal, ocular, and skin physiological processes; or metabolic process, including enzymatic and other pharmacological processes, by a drug or other chemical.

• Depression, Postpartum

  depression in postpartum women, usually within four weeks after giving birth (parturition). the degree of depression ranges from mild transient depression to neurotic or psychotic depressive disorders. (from dsm-iv, p386)

• Depressive Disorder

  an affective disorder manifested by either a dysphoric mood or loss of interest or pleasure in usual activities. the mood disturbance is prominent and relatively persistent.

• Depressive Disorder, Major

  disorder in which five (or more) of the following symptoms have been present during the same 2-week period and represent a change from previous functioning; at least one of the symptoms is either (1) depressed mood or (2) loss of interest or pleasure. symptoms include: depressed mood most of the day, nearly every day; markedly diminished interest or pleasure in activities most of the day, nearly every day; significant weight loss when not dieting or weight gain; insomnia or hypersomnia nearly every day; psychomotor agitation or retardation nearly every day; fatigue or loss of energy nearly every day; feelings of worthlessness or excessive or inappropriate guilt; diminished ability to think or concentrate, or indecisiveness, nearly every day; or recurrent thoughts of death, recurrent suicidal ideation without a specific plan, or a suicide attempt. (dsm-5)

• Depressive Disorder, Treatment-Resistant

  failure to respond to two or more trials of antidepressant monotherapy or failure to respond to four or more trials of different antidepressant therapies. (campbell's psychiatric dictionary, 9th ed.)

• Economic Recession

  significant decline in economic activity spread across the economy, lasting more than a few months, normally visible in real gross domestic product, real income, employment, industrial production, and wholesale-retail sales. (national bureau of economic research, inc, www.nber.org/cycles.html, accessed 4/23/2009)

• Inbreeding Depression

  a reduced genetic variation and genetic fitness due to inbreeding.

• Long-Term Synaptic Depression

  a persistent activity-dependent decrease in synaptic efficacy between neurons. it typically occurs following repeated low-frequency afferent stimulation, but it can be induced by other methods. long-term depression appears to play a role in memory.

• Respiratory Insufficiency

  failure to adequately provide oxygen to cells of the body and to remove excess carbon dioxide from them. (stedman, 25th ed)

• Seasonal Affective Disorder

  a syndrome characterized by depressions that recur annually at the same time each year, usually during the winter months. other symptoms include anxiety, irritability, decreased energy, increased appetite (carbohydrate cravings), increased duration of sleep, and weight gain. sad (seasonal affective disorder) can be treated by daily exposure to bright artificial lights (phototherapy), during the season of recurrence.

• Tooth Movement Techniques

  orthodontic techniques used to correct the malposition of a tooth or teeth.

• Vascular Depression

  late-life depression associated with clinical or mri defined cerebrovascular pathology.

• Migraine with Aura

  a subtype of migraine disorder, characterized by recurrent attacks of reversible neurological symptoms (aura) that precede or accompany the headache. aura may include a combination of sensory disturbances, such as blurred vision; hallucinations; vertigo; numbness; and difficulty in concentrating and speaking. aura is usually followed by features of the common migraine, such as photophobia; phonophobia; and nausea. (international classification of headache disorders, 2nd ed. cephalalgia 2004: suppl 1)

• Reactive Depression

  depression precipitated by events in a person's life.

Depression

Depression is more than a feeling of being sad or irritable for a few days. It's a serious mood disorder. As one of the most common mental disorders in the United States, depression can affect how you think, feel, and your everyday life.
