F33.1: Major Depressive Disorder, Recurrent, Moderate

F33.1, major depressive disorder, recurrent, moderate, is a common diagnosis in outpatient therapy and a common place for charts to become too thin. The code is not simply “depression again.” It requires evidence that the current episode is not the client’s first major depressive episode, that the current episode is moderate rather than mild or severe, and that the depressive presentation is not better explained by bipolar disorder, adjustment disorder, substance use, medication effects, or a medical condition.

For licensed therapists, psychologists, counselors, and clinical social workers who diagnose and bill under ICD-10-CM, this page is part of the ICD-10 codes for therapists sub-hub. It focuses on the documentation pattern: what the intake or progress note should show, how to distinguish recurrence from a single episode, how to support moderate severity, and how to pair the diagnosis with psychotherapy CPT codes without implying that the diagnosis determines the service code.

What the recurrent moderate MDD code means

The ICD-10-CM descriptor for this diagnosis is “Major depressive disorder, recurrent, moderate.” It sits in the F30-F39 mood disorders block. The F33 category covers recurrent major depressive disorder, and the fifth character specifies the current episode’s severity or remission status. The official CMS ICD-10-CM files are the governing US source for the code set, with current code-set materials available through the CMS ICD-10 page.

Two decisions sit underneath the descriptor:

Decision	What the chart must support	Common weak spot
Recurrent	At least one prior major depressive episode, separated from the current episode by a period of remission or meaningful symptom relief.	Prior episodes are mentioned casually but not assessed against MDD criteria.
Moderate	Current episode severity falls between mild and severe: more than minimal symptoms or impairment, but without severe functional collapse or psychotic features.	A PHQ-9 score is absent, or the score is documented without functional impairment.

The diagnosis should not be carried as a shorthand for any client who has felt depressed before. A defensible note names the prior episode history, the current symptom set, the impairment, and the severity rationale in a way another clinician or payer reviewer can follow.

When recurrent moderate depression fits

Use the recurrent MDD family when the current episode follows at least one earlier major depressive episode. The earlier episode does not need to have been treated in your practice, but the record needs enough history to show that it plausibly met MDD criteria: symptom count, duration, impairment, and remission or substantial symptom relief before the present episode.

Moderate severity generally means the client has clear distress and functional impairment, with symptoms or impairment beyond the mild range but not in the severe range. A PHQ-9 score in the 10 to 14 range often supports a moderate specifier, though the score is not the diagnosis by itself. The original PHQ-9 validation work by Kroenke, Spitzer, and Williams is frequently cited for the score bands, and the score should be interpreted alongside client report, risk, role functioning, and clinical judgment.

A chart that supports this code typically shows:

1. A prior episode that met major depressive episode criteria, with approximate dates or life context.
2. A current episode with depressed mood or anhedonia plus enough additional symptoms to meet MDD criteria.
3. Moderate impairment in work, school, parenting, relationships, self-care, or therapy engagement.
4. A risk assessment, including suicidal ideation, plan, intent, means, history, and protective factors.
5. Differential reasoning that makes clear why this is recurrent MDD rather than single-episode MDD, adjustment disorder, bipolar disorder, or substance or medication-induced mood symptoms.

Differential diagnosis therapists should document

The differential is where this code most often becomes vulnerable. The presenting problem may look straightforward, but payer and board review looks for the reasoning that connects the descriptor to the clinical facts.

Differential	Documentation question	Safer chart language
Single-episode MDD	Is this truly recurrent, or is the current episode the first established major depressive episode?	“Client reports a prior depressive episode in 2021 lasting approximately three months, with anhedonia, hypersomnia, fatigue, guilt, and work impairment; symptoms remitted before the current episode.”
Mild or severe recurrent MDD	Does current severity match the moderate specifier?	“PHQ-9 score 13, daily depressed mood, anhedonia, sleep-onset insomnia, missed two workdays this month, no psychotic features, no current plan or intent.”
Adjustment disorder with depressed mood	Are full MDD criteria met, or is the reaction stressor-linked and below MDD threshold?	“Current presentation meets MDD symptom count and duration; job loss is a stressor but does not account for the full syndrome.”
Bipolar disorders	Has the clinician screened for past mania or hypomania?	“Client denies history of manic or hypomanic episodes; no periods of decreased need for sleep with elevated or irritable mood and increased goal-directed activity reported.”
Substance or medical contributors	Could alcohol, other substances, medication, thyroid disease, anemia, sleep apnea, or another medical condition be driving mood symptoms?	“Alcohol use, medication changes, and medical contributors reviewed; client referred to PCP for thyroid and anemia ruleout due to fatigue profile.”

When the recurrent question is not established yet, the safer starting point may be F32.9 major depressive disorder unspecified with a planned history clarification. When the symptoms are stressor-linked and below full MDD threshold, adjustment disorder with depressed mood is the better differential reference.

Documentation pattern for a defensible note

A defensible F33.1 note does not need to be long. It needs to make the clinical reasoning visible. Sofia’s compliance rule is simple: if a reviewer can find the recurrence evidence, severity evidence, risk assessment, treatment-plan link, and differential in under two minutes, the chart is doing its job.

Note element	What to include	Why it matters
History of recurrence	Prior episode dates or context, symptom profile, impairment, remission or improvement between episodes.	Establishes why the F33 family is used instead of F32.
Current symptom evidence	Depressed mood or anhedonia plus additional MDD symptoms, duration, observed affect, sleep, appetite, energy, cognition, guilt, psychomotor change, and thoughts of death when present.	Supports the current major depressive episode.
Severity evidence	PHQ-9 score or comparable measure, functional impairment, risk level, and absence or presence of psychotic features.	Supports the moderate specifier and distinguishes mild or severe codes.
Risk assessment	Ideation, plan, intent, means, history, protective factors, clinical response, and safety plan when indicated.	Depression charts are high-risk charts; risk documentation is not optional.
Differential	Single vs recurrent MDD, adjustment disorder, bipolar disorders, substance or medical contributors, and persistent depressive disorder when chronicity suggests it.	Shows that the code is a reasoned clinical conclusion rather than a label.
Treatment-plan link	Goals tied to symptom reduction, functioning, risk stabilization, measurement cadence, and modality plan.	Demonstrates medical necessity and ongoing clinical direction.

A concise assessment paragraph might read: “Client meets criteria for recurrent MDD, current episode moderate: prior MDE in college with three-month duration and role impairment, full remission by report before current episode; current four-week episode includes depressed mood, anhedonia, insomnia, fatigue, concentration difficulty, and worthlessness with PHQ-9 score 13 and reduced work attendance. Denies mania or hypomania. Passive thoughts of death without plan, intent, or means; protective factors include spouse, children, and treatment engagement. Presentation exceeds adjustment-disorder threshold and is not better explained by substances or known medical condition.”

Measurement and CPT context

For F33.1, measurement-based care gives the moderate specifier something concrete to rest on. The PHQ-9 is common because it is brief, familiar to payers, and easy to trend. A score in the moderate range should be interpreted with clinical judgment, not copied into the diagnosis line without context. A client with a score of 13 and mild functional impairment may need a different severity rationale than a client with the same score plus missed work, daily withdrawal, and rising risk.

For practical measure selection and score cadence, the measurement-based care guide for therapists covers PHQ-9, GAD-7, PCL-5, ORS/SRS, and common implementation patterns. In a recurrent moderate depression chart, the most useful cadence is usually intake, a session-three or session-four recheck, and then every four to six sessions during active treatment.

The diagnosis code does not determine the CPT code. The CPT code describes the service delivered. Common therapy pairings include 90791 for the diagnostic evaluation, 90834 for a routine 45-minute psychotherapy session, and 90837 when the time and medical necessity support a longer psychotherapy session. Document the session time, intervention, risk work, and treatment-plan connection separately from the diagnosis.

How Emosapien supports recurrent-depression documentation

Emosapien’s Scribe Agent drafts therapy notes from in-session clinical context while the clinician stays responsible for diagnosis, coding, and final sign-off. In a recurrent depression intake, the useful administrative support is not an autonomous code assignment. It is a cleaner draft Assessment that keeps the prior-episode history, current symptom evidence, risk language, PHQ-9 score, differential reasoning, and treatment-plan link in one reviewable place.

That matters because recurrent MDD charts become vulnerable when the reasoning is scattered: prior episode in the history, PHQ-9 score in a form, risk in a sidebar, and the diagnosis line sitting alone. A clinician-reviewed draft note can keep those pieces connected, so the final record tells the same story the therapist actually assessed in session.

FAQ

Is F33.1 appropriate for a client with a PHQ-9 score of 13?

Possibly, but the score is not enough by itself. A PHQ-9 score of 13 sits in the moderate range, but the chart still needs recurrent-episode history, MDD symptom criteria, functional impairment, risk assessment, and differential reasoning.

Can a therapist use this diagnosis at intake?

Yes, when the intake establishes both recurrence and moderate current severity. If the prior-episode history is unclear or severity is not yet supported, document the uncertainty and use the code that best reflects what the chart can support today.

Does the code require medication management?

No. The code identifies the diagnosis, not a treatment modality. A therapist may treat recurrent moderate depression with psychotherapy when it fits the client’s needs and scope of practice. Referral for medication evaluation may be clinically appropriate based on severity, risk, client preference, treatment history, and local scope rules.
