ICD-10 codes for Major depression, Moderate depression, Postnatal depression and Postnatal depression from October 2015 will be specify used for medical billing and coding of depressive disorder.
Depression also known as dysthymic disorder is a common condition that affects the brain attributed to a variety of genetic, environmental, psychological and biochemical factors. The condition affects over 20 million people in the US and manifests itself in early ages of up to 15 years old.
Depression causes reduction in productivity in people increased absenteeism and can cause other chronic illnesses such as arthritis asthma cancer diabetes and obesity when not detected early enough and necessary medical attention taken.
A patient enduring depression suffers from lower mood levels, reduction in energy levels, a decrease in activities and most of the time accompanied with memory loss. Sleep patterns are usually disturbed by depression accompanied with reduced appetite levels and feeling of self- unworthy. ICD-10 has revised its classification of the different conditions attributed to depression, under ICD-10 depression will be classified as:
- Agitated Depression
- Major Depression w/o Psychotic Symptoms
- Vital Depression
ICD-10 Code for Depression and Anxiety (Moderate, Severe, Bipolar)
ICD-10 unlike ICD-9 will classify depression in terms of it being mild, moderate, and severe and with or without psychotic features.
A clear example is the ICD-10 code F32.2 that will be used to specify any major depressive disorder that is a single episode without any psychotic features. F33.0 on its part will be used to specify a major depressive disorder being recurrent and mild with F33.41 being used to designate major depressive disorder that is recurrent with partial remission.
ICD-10 Codes for Bipolar Disorder
Bipolar disorder is one of the major mental illnesses in which people experience dramatic mood swings, One can go from being highly energetic high and irritable to sad and hopeless in blink of an eye. ICD-10 code F31.1 in this case will be used to specify a bipolar disorder that is mild without any psychotic features. F31.64 on the other hand will specify any bipolar disorder that is severe accompanied with psychotic features.
ICD-10 Codes for Bipolar disorder II with Mood swings
Bipolar 2 is similar to bipolar 1 characterized with mood swings cycling between high and low over time, the only difference in this case is that the mood swings never reach full on mania. F31.8 ICD-10 code will thus be used to specify the Bipolar II disorder. Depression associated with psychotic symptoms will be specified by F32.3 while F06.32 will be used to specify any mood disorder caused by known psychological conditions with major depressive like episodes.
ICD-10 Codes for Cyclothymia and Dysthymic Disorder
Cyclothymia is a term used to specify any type of depression characterized by persistent instability of mood swings accompanied with mild elation. The condition is common in relatives with bipolar parents. Dysthymia on its part is a chronic depression of moods that lasts for years. This condition is not severe with its episodes not being prolonged to justify diagnosis of either mild moderate or severe. ICD-10 will rely on F34 to specify Cyclothymic disorder and F34.1 for Dysthymic disorder.
Generally speaking, ICD-10 codes for depressive disorders are grouped under several categories:
F32 - Major depressive disorder, single episode
The intent of this category, from what I understand, is to include single episodes of major depression. There are several ICD-10 codes that can be used here, depending on severity, the presence of any associated symptoms, and whether the episode of depression is in partial of full remission (note that F32 is NOT a billable code):
- F32.0 - Major depressive disorder, single episode, mild
- F32.1 - Major depressive disorder, single episode, moderate
- F32.2 - Major depressive disorder, single episode, severe without psychotic features
- F32.3 - Major depressive disorder, single episode, severe with psychotic features
- F32.4 - Major depressive disorder, single episode, in partial remission
- F32.5 - Major depressive disorder, single episode, in full remission
- F32.8 - Other depressive episodes
- F32.9 - Major depressive disorder, single episode, unspecified
ICD-10 Code F33 Major Depressive Disorder, Recurrent
F33 codes are similar to F32, except that they refer to recurrent episodes of major depression:
- F33.0 - Major depressive disorder, recurrent, mild
- F33.1 - Major depressive disorder, recurrent, moderate
- F33.2 - Major depressive disorder, recurrent severe without psychotic features
- F33.3 - Major depressive disorder, recurrent, severe with psychotic symptoms
- F33.4 - Major depressive disorder, recurrent, in remission
- F33.40 - Major depressive disorder, recurrent, in remission, unspecified
- F33.41 - Major depressive disorder, recurrent, in partial remission
- F33.42 - Major depressive disorder, recurrent, in full remission
- F33.8 - Other recurrent depressive disorders
- F33.9 - Major depressive disorder, recurrent, unspecified
F32 and F33 codes for depression correspond to 296.xx codes under the ICD-9-CM classification. The exception is ICD-9 code 298.0 - Depressive type psychosis), which in ICD-10 correspondds to F32.3 - Major depressive disorder, single episode, severe with psychotic features, and F33.3 - Major depressive disorder, recurrent, severe with psychotic symptoms.
ICD-9 code 311 (Depressive disorder, not elsewhere classified) translates to ICD-10 code F32.9 (Major depressive disorder, single episode, unspecified).
Other ICD-10 Codes For Depression
- F03.90 (Unspecified dementia without behavioral disturbance)
- 290.13 - Presenile dementia with depressive features
- 290.21 - Senile dementia with depressive features
- F34.1 (Dysthymic disorder) corresponds to ICD-9 code 301.12 (Chronic depressive personality disorder)
- F43.21(Adjustment disorder with depressed mood) is tranlated from 309.1 (Prolonged depressive reaction)
- 293.83 (Mood disorder in conditions classified elsewhere) has been expanded to two ICD-10-CM codes:
- F06.31 - Mood disorder due to known physiological condition with depressive features
- F06.32 - Mood disorder due to known physiological condition with major depressive-like episode
- Finally, F25.1 (Schizoaffective disorder, depressive typ) translates 295.70 (Schizoaffective disorder, unspecified)
Mental disorders come with serious consequences when not properly treated which may lead to increased blood pressure that can lead to a fatality. It is always good to seek medical attention as early as possible to stand a better chance of arresting the condition Coders will also be required to have a comprehensive understanding of the various disorders associated with Depression to extract proper information for billing and coding .
