A properly written DSM-5 diagnosis for major depressive disorder includes the disorder name, the episode type (single or recurrent), the severity level, and any applicable specifiers, all in a specific order. The full diagnostic statement might look something like: Major Depressive Disorder, Single Episode, Moderate, With Anxious Distress. Each component conveys clinical information that shapes treatment planning and insurance documentation.
The Core Diagnostic Criteria
Before you can write the diagnosis, the clinical picture needs to meet the DSM-5’s threshold. The manual lists nine possible symptoms of a major depressive episode:
- Depressed mood most of the day, nearly every day
- Markedly diminished interest or pleasure in activities (anhedonia)
- Significant weight loss or gain, or changes in appetite
- Insomnia or hypersomnia
- Psychomotor agitation or retardation observable by others
- Fatigue or loss of energy
- Feelings of worthlessness or excessive guilt
- Difficulty concentrating or making decisions
- Recurrent thoughts of death or suicidal ideation
At least five of these nine symptoms must be present during the same two-week period, and at least one of those five must be either depressed mood or anhedonia. The symptoms also need to cause clinically significant distress or impairment in social, occupational, or other important areas of functioning. A person who meets symptom count but is functioning normally in all domains would not qualify.
The episode cannot be better explained by substance use, a medication side effect, or another medical condition. It also cannot occur in the context of a manic or hypomanic episode, which would point toward a bipolar diagnosis instead.
Structure of the Written Diagnosis
The DSM-5 diagnosis follows a specific format. Each piece is written in sequence, separated by commas:
Disorder Name, Episode Type, Severity, Specifiers
Here’s what each component means in practice.
Episode Type
You designate the episode as either “single episode” or “recurrent.” A single episode means this is the person’s first major depressive episode. Recurrent means they’ve had at least two episodes, with a gap between them where they no longer met full criteria. If the person had depression five years ago, recovered, and now meets criteria again, the episode type is recurrent.
Severity
The DSM-5 recognizes three severity levels for a current episode: mild, moderate, and severe. Mild generally means the person barely meets the five-symptom threshold and impairment is present but manageable. Moderate falls between mild and severe, with more symptoms or greater functional difficulty. Severe applies when nearly all nine symptoms are present and functioning is seriously disrupted. Clinicians often use the PHQ-9 as a standardized tool to support severity ratings: scores of 5 to 9 correspond to mild depression, 10 to 14 to moderate, 15 to 19 to moderately severe, and 20 to 27 to severe.
Remission Status
If the person previously met criteria but symptoms have improved, you replace the severity level with a remission qualifier. “In partial remission” means some symptoms are still present, but the person no longer meets full diagnostic criteria. “In full remission” means no significant signs or symptoms have been present for at least two months. You would not list both a severity level and a remission status at the same time.
Adding Clinical Specifiers
Specifiers come at the end of the diagnostic statement and provide additional clinical detail. The DSM-5 offers several options for major depressive disorder, and you include only those that apply. Common specifiers include:
- With anxious distress: The person feels keyed up, tense, or restless alongside their depression, or has difficulty concentrating due to worry.
- With melancholic features: The depression has a distinct quality of profound emptiness, is consistently worse in the morning, and includes significant loss of pleasure in nearly all activities.
- With atypical features: Mood brightens in response to positive events, and the person experiences increased appetite, excessive sleep, heavy feelings in the limbs, or sensitivity to rejection.
- With peripartum onset: Symptoms begin during pregnancy or within four weeks of delivery.
- With seasonal pattern: Episodes consistently occur at a specific time of year, most commonly fall or winter.
- With psychotic features: The person experiences delusions or hallucinations during the depressive episode. This is further specified as mood-congruent or mood-incongruent.
Multiple specifiers can be listed when applicable. For example, a person could have melancholic features and anxious distress simultaneously.
Matching the ICD-10-CM Code
Every DSM-5 diagnosis needs a corresponding ICD-10-CM code for billing and medical records. Major depressive disorder uses two code families. Single episodes fall under F32, and recurrent episodes fall under F33. The final digit indicates severity or remission status:
- F32.0 — Single episode, mild
- F32.1 — Single episode, moderate
- F32.2 — Single episode, severe (without psychotic features)
- F32.3 — Single episode, severe with psychotic features
- F32.4 — Single episode, in partial remission
- F32.5 — Single episode, in full remission
- F33.0 — Recurrent, mild
- F33.1 — Recurrent, moderate
- F33.2 — Recurrent, severe (without psychotic features)
- F33.3 — Recurrent, severe with psychotic features
- F33.41 — Recurrent, in partial remission
- F33.42 — Recurrent, in full remission
The ICD code is typically written before the diagnostic name in clinical documentation. So a complete entry in a chart might read: F33.1 Major Depressive Disorder, Recurrent, Moderate, With Anxious Distress.
Full Examples of Written Diagnoses
Seeing the complete format helps clarify how the pieces fit together. Here are several examples covering different clinical presentations:
- F32.0 Major Depressive Disorder, Single Episode, Mild
- F32.2 Major Depressive Disorder, Single Episode, Severe, With Melancholic Features
- F33.1 Major Depressive Disorder, Recurrent, Moderate, With Anxious Distress
- F33.3 Major Depressive Disorder, Recurrent, Severe, With Mood-Congruent Psychotic Features
- F33.41 Major Depressive Disorder, Recurrent, In Partial Remission
Notice that specifiers only appear when clinically relevant. A straightforward moderate episode without additional features does not need any specifier at all.
Common Formatting Mistakes
One frequent error is omitting the episode type. Writing “Major Depressive Disorder, Moderate” without specifying single or recurrent leaves the diagnosis incomplete. Another is assigning a severity level and a remission qualifier at the same time, which is contradictory: the person is either currently in an active episode (rated by severity) or in remission.
Failing to rule out bipolar disorder is a diagnostic error rather than a formatting one, but it shows up in documentation problems. If there is any history of manic or hypomanic episodes, the correct diagnosis shifts to a bipolar spectrum disorder, and the MDD code should not be used. Similarly, if the depressive symptoms are clearly caused by a substance or a medical condition like hypothyroidism, a different diagnostic category applies.
The DSM-5-TR, published in 2022, made a small but meaningful revision to how MDD relates to psychotic disorders. Under the updated text, a major depressive episode can be diagnosed as “superimposed on” a psychotic disorder like schizophrenia, rather than being automatically excluded by it. This affects a narrow clinical population but is worth noting for accuracy in current documentation.
