F43.22: A Therapist's Reference for Adjustment Disorder with Anxiety

Adjustment disorder with anxiety is the diagnostic home for clients whose worry, nervousness, restlessness, or jitteriness follows a clear life stressor and does not meet the threshold for generalized anxiety disorder. The presentation is one outpatient therapists see often: a recent job change, a relocation, a parent’s diagnosis, a child starting school, a divorce filing, a custody dispute, a looming court date, followed by ruminative worry that orbits the stressor, sleep onset difficulty, somatic tension, and a reduction in role functioning. The client can name the stressor and date its onset; the anxiety picture is real but does not meet the six-month duration test, the breadth-of-worry test, or the symptom-count test that GAD requires.

What separates a defensible adjustment-with-anxiety chart from a vulnerable one is whether the GAD differential is visibly closed off in writing. The audit objection raised most often against this code is exactly that: the chart documents anxiety symptoms, the chart documents a stressor, and the chart never explicitly addresses why the symptom picture does not meet generalized anxiety disorder. When the GAD ruleout is in the assessment in plain language, this code becomes one of the more defensible diagnoses in outpatient therapy.

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. The DSM-5 criteria, the F43.2x family logic, the GAD and acute stress reaction differentials, the audit-ready documentation pattern, and the CPT pairings each get their own section below.

What f43.22 means in ICD-10-CM

ICD-10-CM defines f43.22 as “Adjustment disorder with anxiety.” The code sits inside the F40-F48 parent block (anxiety, dissociative, stress-related, somatoform, and other nonpsychotic mental disorders). Inside that block, F43 is the category for “Reaction to severe stress, and adjustment disorders,” which groups acute stress reactions, post-traumatic stress disorder, and the adjustment-disorder subtypes together because they share an identifiable precipitating stressor.

F43.2 narrows to “Adjustment disorders,” and the fifth-character specifier identifies the predominant symptom pattern. The anxiety specifier is appropriate when nervousness, worry, jitteriness, and (in children) separation-related anxiety predominate, and depressive symptoms are either absent or clinically minimal. The official descriptor is published by the Centers for Medicare and Medicaid Services and mirrored at icd10data.com, with the broader CMS reference at the CMS ICD-10 page. The DSM-5 itself, published by the American Psychiatric Association, aligns the diagnostic criteria with the ICD code, although the ICD descriptor is what payers expect to see on the claim line. Use the descriptor wording as published; reviewers expect the specifier language to match the official text rather than a paraphrase.

DSM-5 criteria for adjustment disorders

The DSM-5 criteria for the F43.2x family are five lettered criteria, A through E, that together establish the diagnosis. The summary table is intended for quick chart-side reference; the full descriptors live in the DSM-5 itself.

Criterion	What it requires	Threshold for the chart
A: Stressor and timing	Development of emotional or behavioral symptoms in response to an identifiable stressor occurring within three months of the stressor’s onset.	Name the stressor and date it. Document symptom onset within the three-month window.
B: Clinical significance	Marked distress out of proportion to severity of the stressor (taking cultural context into account) OR significant impairment in social, occupational, or other important functioning.	Concrete impacts on work, relationships, sleep, or daily routine.
C: Differential	Disturbance does not meet criteria for another mental disorder and is not merely an exacerbation of a preexisting one.	GAD, panic disorder, social anxiety, acute stress reaction, PTSD, and adjustment-as-exacerbation of a preexisting anxiety disorder explicitly considered and ruled out.
D: Bereavement	Symptoms do not represent normal bereavement.	If the stressor is a death, document why the response exceeds normative grief.
E: Duration	Once the stressor or its consequences end, symptoms do not persist for more than an additional six months.	The chart establishes that symptoms remain proportionate to the ongoing stressor, or that resolution is occurring as the stressor resolves.

Two duration specifiers attach. Acute applies when the disturbance has lasted less than six months. Persistent (or chronic) applies when the disturbance has lasted six months or longer; the stressor or its consequences must still be present for the diagnosis to persist beyond six months, otherwise Criterion E rules the diagnosis out. Both duration specifiers attach to the anxiety code the same way they attach to the other F43.2x specifiers, and the chart should name which one applies once the timeline supports the call.

The specifier sentence in DSM-5 is “with anxiety: nervousness, worry, jitteriness, or separation anxiety is predominant.” The “predominant” word is the operative one for chart review. A presentation that is roughly half anxiety and half low mood does not get this specifier; that picture is F43.23. A presentation that is anxiety-led with low mood as a small secondary feature is correctly coded with the anxiety specifier (the secondary mood note belongs in the formulation rather than driving the specifier).

When f43.22 is the right pick over a different specifier

The choice between the F43.2x specifiers is driven by which symptom cluster predominates and by how confident the chart is in naming it. The anxiety specifier has a clear lane when the symptom picture is worry-led without a depression-cluster co-presentation that would shift the chart to F43.23.

Code	Subtype	When to use
F43.20	Unspecified	The predominant subtype is not yet clear at initial diagnosis, or the presentation does not align cleanly with one of the specified subtypes. Use sparingly; reviewers expect resolution to a specifier within a few sessions.
F43.21	With depressed mood	Low mood, tearfulness, hopelessness predominate. Anxiety symptoms are absent or minimal. For the documentation specifics, see the F43.21 adjustment disorder with depressed mood guide.
f43.22	With anxiety	Worry, nervousness, jitteriness, separation-related anxiety predominate. Depressive symptoms are absent or minimal.
F43.23	With mixed anxiety and depressed mood	Both anxiety and depressive symptom clusters are clinically significant. Neither alone would justify the .21 or .22 specifier.
F43.24	With disturbance of conduct	The presentation is dominated by behavior that violates norms or rules (more common in adolescents).
F43.25	With mixed disturbance of emotions and conduct	Both emotional symptoms (anxiety, depression) and conduct disturbance are present.

The chart-side test that resolves the anxiety specifier from F43.23 is whether the depressive symptoms reach clinical significance on their own. If the client endorses low mood as a brief reactive feature (“I felt down for an evening after the call”) without anhedonia, persistent hopelessness, sleep changes attributable to depression, or sustained reduction in interest, the picture is anxiety-predominant and the .22 specifier holds. If the depressive symptoms cluster meaningfully (two or three of: persistent low mood, anhedonia, hopelessness, fatigue, appetite or sleep changes that read as depression rather than anxiety), the chart should code F43.23 instead.

Differential: f43.22 versus generalized anxiety disorder (F41.1)

This is the most important differential for this code, and the one auditors and licensing reviewers focus on first. F41.1 (generalized anxiety disorder) and the anxiety specifier share the surface presentation of worry, but the criteria diverge on three measurable dimensions: duration, breadth of worry, and the presence of an identifiable precipitating stressor. The detail on the GAD criteria themselves lives in the F41.1 generalized anxiety disorder guide; the table below captures what the chart needs to show to defend the adjustment-with-anxiety pick over F41.1.

Dimension	F43.22 (adjustment with anxiety)	F41.1 (generalized anxiety disorder)
Duration of worry	Symptoms begin within three months of stressor onset; resolve within six months of stressor termination.	Excessive worry occurring more days than not for at least six months.
Breadth of worry	Worry orbits the identified stressor and its proximate consequences.	Worry spans multiple unrelated domains (work, health, finances, family, minor matters).
Identifiable stressor	Required. The stressor is named, dated, and proximate to symptom onset.	Not required. The worry is the disorder, independent of any specific precipitant.
Associated symptoms	Variable and tied to the stressor (sleep-onset insomnia about the worry topic, somatic tension during stressor-relevant moments).	At least three of six: restlessness, fatigue, concentration difficulty, irritability, muscle tension, sleep disturbance.
Treatment-plan duration	Time-limited; aligned to the six-month post-stressor window.	Open-ended; chronic course is expected.

The duration test is the single highest-signal element in the chart. When a client describes worry that began within the last three months and centers on a named stressor, the adjustment-with-anxiety pick is defensible. When the client describes worry that has been present for a year or more, spans multiple unrelated domains, and would persist even if the current stressor resolved, the chart should code F41.1. A presentation that began as a stress reaction but has now persisted past six months without the stressor changing should trigger reconsideration of the diagnosis and, often, a recode to F41.1 with the documented clinical reasoning visible in the chart.

The breadth-of-worry test is equally important. A client whose worry orbits the upcoming custody hearing, the legal fees, the impact on the children, and the logistics of the new shared-parenting calendar is worrying about one stressor and its proximate consequences. That is the adjustment-with-anxiety picture. A client whose worry rotates daily between unrelated topics (a vague fear about a medical scan, a small work deadline, the children’s friendships, a partner’s mood, household finances, a news story) is exhibiting GAD-pattern worry independent of any single stressor.

Differential: f43.22 versus acute stress reaction (F43.0) and PTSD (F43.10)

The other differential cluster sits inside the F43 family itself. The decision turns on whether the stressor meets the Criterion A trauma threshold for PTSD and on the timeline since the index event.

Code	Condition	Differentiator from this code
F43.0	Acute stress reaction	Applies in the first month after exposure to a traumatic stressor. The stressor must meet the Criterion A threshold (actual or threatened death, serious injury, or sexual violence). The anxiety specifier applies when the stressor is identifiable but does not meet the Criterion A trauma threshold.
F43.10	PTSD, unspecified	Requires a Criterion A traumatic stressor and the four-cluster PTSD architecture (intrusion, avoidance, negative cognitions/mood, arousal/reactivity). Adjustment disorder applies when the stressor is identifiable but does not cross the Criterion A trauma threshold.
F43.8	Other reactions to severe stress	A stress reaction documented but not fitting the more specific F43 codes. Used sparingly.
F43.9	Reaction to severe stress, unspecified	Even more general than the unspecified adjustment code; the stress reaction is documented but the type cannot be specified. Reviewers expect resolution to a more specific code quickly.

The Criterion A distinction settles the most common F43 confusion at intake. PTSD requires exposure to actual or threatened death, serious injury, or sexual violence; adjustment disorder applies when the stressor is identifiable but falls short of that threshold (a job loss, a difficult divorce, a recent diagnosis of a non-life-threatening condition, a geographic relocation, a workplace conflict). A client whose stressor is at the trauma threshold but whose symptom picture has not yet declared whether it meets full PTSD criteria is in the F43.0 acute stress reaction lane for the first month, not the adjustment-with-anxiety lane.

Beyond the F43 family, the chart should also rule out the panic disorder (F41.0), social anxiety disorder (F40.10), specific phobia (F40.2x), and borderline personality disorder (F60.3) presentations when the clinical features overlap. Panic disorder requires recurrent unexpected panic attacks; situational anxiety pinned to a stressor does not meet that criterion. Social anxiety disorder centers on fear of negative evaluation in social or performance situations; if the worry is exclusively social and predates the stressor, F40.10 is the better pick. The borderline personality disorder differential (F60.3) applies when relational instability and identity disturbance accompany the anxiety symptoms.

Documentation that holds up under audit

A defensible adjustment-with-anxiety chart establishes six elements at intake and revisits them in subsequent sessions until the durational picture is clear.

1. The stressor is named and dated specifically. “Recent stressor” is not enough. The chart should identify what the stressor is (job termination on a specific date, custody filing on a specific date, medical diagnosis received in a specific week) and document that symptom onset followed within the three-month window required by Criterion A. Vague language (“life stress”) does not satisfy the criterion under review.
2. Anxiety symptom cluster documented with concrete client report. Worry content, restlessness, irritability, sleep-onset difficulty, somatic tension; each with supporting evidence from session content. Generic language (“client endorses anxiety symptoms”) is weaker than specific report (“client reports lying awake 60 to 90 minutes most nights replaying the custody mediation, daily muscle tension across the shoulders, hourly intrusive thoughts about the next court date”).
3. GAD differential explicitly closed off. A brief note that the client does not meet F41.1 criteria (worry tied to the identified stressor rather than excessive across multiple unrelated domains, duration shorter than the six-month GAD threshold, no clear chronic pre-stressor worry baseline) closes the most common audit objection in advance. The chart that uses the code without ever addressing the differential is the chart an auditor flags first.
4. PTSD differential addressed when the stressor approaches the trauma threshold. If the stressor could be read as Criterion A trauma (a serious accident, a violent event witnessed, a sexual assault disclosure), the note should explicitly explain why the chart frames the presentation as adjustment disorder rather than PTSD or acute stress reaction.
5. Functional impairment described concretely. Missed work days, withdrawal from previously valued activities, sleep disruption, decreased productivity, role-function changes in parenting or partnership. Specific, observable impacts are stronger than generic phrasing.
6. Treatment plan tied to the stressor with a planned re-evaluation point. The plan should target symptom reduction during the durational window built into the diagnosis and identify the session number or assessment point at which the diagnosis will be revisited. A plan that says “diagnosis will be re-evaluated at session six; if symptoms persist beyond six months after stressor resolution, the chart will reconsider F41.1 or a related anxiety disorder” is exactly the pattern auditors read favorably.

Validated screeners strengthen the chart. The GAD-7 (Generalized Anxiety Disorder 7-item scale) administered at intake and again at session six creates a repeatable measurement an auditor can read at a glance. A GAD-7 score in the mild-to-moderate range that does not climb supports the adjustment-disorder framing; a score that persists at moderate-to-severe levels for several months after stressor resolution should trigger reconsideration of the F41.1 differential. The PHQ-9 administered alongside is a useful negative finding: a low PHQ-9 with an elevated GAD-7 supports the .22 specifier over the .23 mixed specifier.

The American Psychological Association’s record-keeping guidance and the HIPAA provisions at 45 CFR § 164.501 distinguish between psychotherapy notes, which are kept separate and receive heightened protection, and the progress notes that go into the medical record. Diagnostic justification belongs in the progress note and the treatment plan, not in psychotherapy notes, because the progress note is what supports the billed diagnosis under audit.

Clinical use in therapy

In outpatient practice, this code commonly applies to clients presenting after a discrete life event with an anxiety-predominant picture: a job change, a relocation, a parent’s medical diagnosis, a child starting school, a custody dispute, a looming court date, a workplace performance review, a financial setback, or a significant role change at work. The presentation is often clearer than GAD because the client can point to the stressor and date its onset.

Modality fit follows from the clinical picture. Cognitive behavioral therapy is well matched because it gives structure for examining the cognitive distortions that often emerge around the stressor (catastrophizing about the court date, overestimating threat probability around the medical scan, fortune-telling about the job market). Brief acceptance and commitment therapy fits clients whose distress centers on values disruption and meaning-making after the stressor. Brief, time-limited therapy aligns with the six-month durational expectation: if the stressor has resolved or is resolving, the treatment plan can reasonably target symptom reduction over eight to sixteen sessions rather than open-ended care.

For the treatment-plan template that pairs cleanly with this diagnosis, see the anxiety treatment plan template guide on the treatment-plans hub.

CPT codes commonly paired with f43.22

The diagnostic code identifies the condition; the procedure code identifies the service rendered. The CPT codes most commonly paired with this diagnosis are 90791 for the diagnostic evaluation at intake (no medical services), 90832 for psychotherapy of approximately 30 minutes, 90834 for approximately 45 minutes (the most common routine code in outpatient practice), and 90837 for approximately 60 minutes when the work warrants the longer time band. Add-on code 90785 for interactive complexity may apply when communication factors complicate the session.

CPT code	Service	When it fits the chart
90791	Psychiatric diagnostic evaluation (no medical services)	The intake encounter where the diagnosis is established.
90832	Psychotherapy, ~30 minutes	Brief follow-up session, often used early in the treatment course when work is symptom-focused.
90834	Psychotherapy, ~45 minutes	The most common routine code for ongoing weekly therapy.
90837	Psychotherapy, ~60 minutes	When session content and time documentation support the longer band; often used for trauma-adjacent stressor processing.
90785	Interactive complexity add-on	When communication factors (interpreter, third-party involvement, escalated emotional content) complicate the session.
99204	New patient evaluation (E/M, prescribers only)	When a prescriber on staff conducts the new-patient evaluation. For the documentation specifics, see the 99204 new patient evaluation guide.

The diagnostic and procedure codes travel together on the claim line. This code should appear as the primary diagnosis pointer on each psychotherapy CPT line during the active treatment episode. Time-based codes require time documentation in the note that supports the code billed; payers routinely deny 90837 when the note does not establish that the session ran to the time threshold.

When to update the diagnosis

The durational expectation built into Criterion E is what makes adjustment disorder distinct from the chronic anxiety disorders, and it is also what most often triggers a recode. Three patterns deserve explicit attention in the chart.

The first is symptom resolution within the six-month window. When the stressor has terminated and the symptoms have resolved within six months, the diagnosis has done its job and the chart documents discharge or a transition to maintenance work under a different code or no diagnosis. The treatment summary should note the resolution date and tie it to the stressor timeline.

The second is symptom persistence past the six-month window. If symptoms persist beyond six months after the stressor has terminated, Criterion E rules out the adjustment-disorder diagnosis. The chart should reconsider the differential. If the symptom picture has consolidated into chronic worry across multiple unrelated domains, the recode is to F41.1. If the picture has shifted toward a depressive predominance, the recode is to F32.x (single episode) or F33.x (recurrent) depending on the history. If the picture remains stressor-anchored but the stressor itself is enduring (ongoing illness, prolonged unemployment, sustained caregiving role), the persistent specifier on this code may still apply, but the chart should explain why the stressor is read as enduring rather than terminated.

The third is the picture shifting to mixed. If the client’s anxiety predominance gives way to a co-equal depressive cluster, the chart should recode to F43.23 and explain the symptom shift in the progress note. The recoded specifier replaces the prior anxiety specifier on subsequent claim lines.

Common errors that draw audit attention

Three patterns recur in adjustment-with-anxiety charts that fail review, and each is preventable at intake.

The first is the missing GAD differential. A chart that codes this specifier without ever explaining why the picture is not generalized anxiety disorder leaves the most common audit objection unanswered. The fix is a one-line differential note in the assessment that names the duration test (less than six months), the breadth-of-worry test (orbits the identified stressor), and the stressor requirement.

The second is the indefinite carry past six months. A chart that codes this specifier at intake and continues with the same code for more than six months after the stressor has resolved is, to an auditor, a chart that violates Criterion E. The fix is the planned re-evaluation point in the treatment plan and the actual recode (or the documented rationale for continuing the diagnosis when the stressor is genuinely ongoing).

The third is the missing or vague stressor. The adjustment-disorder framework cannot stand without an identifiable stressor named and dated in the chart. When the intake note is vague about what triggered the presentation, or when the timeline does not support symptom onset within three months of the stressor, Criterion A fails and the diagnosis is not defensible. The fix is a specific stressor description in the intake assessment, with a date or close approximation.

How Emosapien handles f43.22 during the session

Emosapien’s Scribe Agent works alongside the clinician as an active co-therapist during intake and ongoing sessions. When the conversation establishes a recent identifiable stressor, an anxiety-predominant symptom cluster, timing within the three-month window, and the absence of full GAD criteria, the agent surfaces this code as a diagnostic candidate alongside the criteria checklist and the GAD differential. The clinician reviews the suggestion, accepts or revises it, and the Assessment section of the progress note populates with the criterion-by-criterion mapping, the stressor description, and the differential reasoning that supports the anxiety-specifier pick.

When a later session shows the symptom picture shifting (the worry generalizing across unrelated domains, the depression cluster emerging, or the timeline crossing the six-month threshold without stressor change), the agent flags the recode opportunity in the next note draft with the supporting evidence inline (the GAD-7 trajectory, the PHQ-9 score, the symptom-content changes reported between sessions). The chart’s diagnostic trail shows the move to F43.23, F41.1, or F32.x with the supporting evidence visible to a chart reviewer, which is exactly the pattern auditors look for. This is not coding automation. The clinician makes the diagnosis. The agent surfaces the candidate, shows its work against the DSM-5 criteria and the ICD-10-CM descriptor, and produces an Assessment that is ready for chart review without retyping.
