Mental health ICD-10 coding<\/a> is not just a code lookup task. The diagnosis code must correspond with the provider’s note, the service billed and the amount of detail known at that visit. This 2026 billing reference provides U.S. mental health practices with a useful reference for the most frequent ICD-10-CM codes, documentation concerns, and coding errors that may impact mental health claims.<\/p>\n\n\n\n\n\n\n\n

A patient’s depression, anxiety, trauma symptoms, substance use, sleep and medication management needs may all occur in the context of billing work. A vague code can slow down the payment or cause a code review from the payer or weaken the claim’s strength compared to the note’s strength.<\/p>\n\n\n\n

2026 update note<\/strong>: This guide covers U.S. ICD-10-CM coding for FY 2026. For encounters from April 1, 2026 through September 30, 2026, use the official April 1, 2026 ICD-10-CM update files and guidelines. Always verify the final code in the current ICD-10-CM Tabular List before submitting a claim.<\/p>\n\n\n\n

What Are ICD-10 Codes for Mental Health?<\/h2>\n\n\n\n

ICD-10-CM codes are diagnosis codes used in the United States to specify the condition of a patient in a claim, report, for medical necessity, and for healthcare records. <\/p>\n\n\n\n

Codes are used to indicate diagnoses, which include depression, anxiety disorders, bipolar disorder, PTSD, ADHD, schizophrenia, substance use disorders, eating disorders, and adjustment disorders where mental health billing is concerned.<\/p>\n\n\n\n

The majority of diagnosis codes in mental health will be in the F01-F99 category. The title of this chapter is Mental, Behavioral and Neurodevelopmental Disorders according to ICD-10-CM.<\/p>\n\n\n\n

In billing, the ICD-10-CM code answers this question:<\/p>\n\n\n\n

Why was the patient treated?<\/strong><\/p>\n\n\n\n

The CPT or HCPCS code answers a different question:<\/p>\n\n\n\n

What service was provided?<\/strong><\/p>\n\n\n\n

For example, a therapist may bill a psychotherapy CPT code such as 90834 or 90837, while the ICD-10-CM code explains the diagnosis supporting that service. <\/p>\n\n\n\n

CMS behavioral health billing<\/a> references include psychiatric diagnostic evaluation codes, psychotherapy codes, psychotherapy add-on codes, and group psychotherapy codes used with mental health services. Both codes should match the provider\u2019s note.<\/p>\n\n\n\n

Billable vs Non-Billable ICD-10-CM Codes<\/h2>\n\n\n\n

ICD-10-CM includes categories, subcategories, and final reportable codes. A category such as F31 or F50 can help you find the right code family, but it may not be valid for claim submission.<\/p>\n\n\n\n

For billing, use the final billable code supported by the provider\u2019s note. If a code family has more detailed options, confirm the exact code in the current ICD-10-CM Tabular List before submitting the claim.<\/p>\n\n\n\n

This matters because a code list may show a code family for navigation, while the claim requires a full code. The golden rule is to pick the “most specific” code based on the documentation, without including any unnecessary information.<\/p>\n\n\n\n

Why ICD-10 Accuracy Matters in Mental Health Billing<\/h2>\n\n\n\n

Proper ICD-10 coding ensures a better understanding of why care was required. It also aids in treatment plans<\/a>, authorizations, audits, reporting and patient records.<\/p>\n\n\n\n

A common problem in mental health billing is not that the provider picked a completely wrong diagnosis. In most cases, the documentation just isn’t specific enough for the claim.<\/p>\n\n\n\n

Code F41.1 is more specific than F41.9 when the notation is for generalized anxiety disorder. But if there isn\u2019t enough information in the record for a certain anxiety disorder, then a code F41.9 can be used.<\/p>\n\n\n\n

CMS confirms that sign, symptom, and unspecified codes are acceptable when they most accurately reflect what is known during that encounter. It is also inappropriate to select a more specific code that is not supported by the record.<\/p>\n\n\n\n

It is important in therapy, psychiatry and behavioral health intake. It can take a longer time for the clinician to determine if the symptoms are due to major depressive disorder, adjustment disorder, bipolar disorder, PTSD, grief, substance-induced symptoms or another disorder. Coding should follow what the provider can support at that visit.<\/p>\n\n\n\n

How to Choose the First-Listed Mental Health Diagnosis<\/h2>\n\n\n\n

For outpatient mental health claims, the main mental health condition, problem or reason for the services provided during the visit should generally be the first listed diagnosis.<\/p>\n\n\n\n

When the note contains a focus on the symptoms of PTSD, PTSD should typically be listed first. Depression, anxiety and substance use disorders are included as additional diagnoses if the patient has these disorders; if the disorders do not affect the care, treatment, or management during that encounter, they are not included here.<\/p>\n\n\n\n

If the provider hasn’t officially diagnosed the condition, the first diagnosis listed might be less specific for intake visits. If so, then code the highest level of certainty found in documentation of that visit, including symptoms, unspecified diagnosis or reason for encounter. The official guidelines also state that the entire record should be reviewed to determine the reason for the encounter and the conditions treated.<\/p>\n\n\n\n

Common Mental Health ICD-10 Codes: Quick Billing Table<\/h2>\n\n\n\n

Use this table as a fast reference. Code families are shown for navigation only. Do not submit a code family or range on a claim. Select the exact billable ICD-10-CM code supported by the provider\u2019s note and the current ICD-10-CM Tabular List.<\/p>\n\n\n\n

Depression ICD-10 Codes<\/h2>\n\n\n\n

Depression coding is one of the most common areas where mental health claims become too vague. <\/p>\n\n\n\n

ICD-10 diagnosis codes for depression depend on whether documentation supports depressive symptoms, unspecified depression, single-episode major depressive disorder, or recurrent major depressive disorder.<\/p>\n\n\n\n

Major Depressive Disorder, Single Episode<\/h3>\n\n\n\n

For a single episode of major depressive disorder, common codes include:<\/p>\n\n\n\n

Code<\/strong><\/td>Description<\/strong><\/td><\/tr>
F32.0<\/td>Major depressive disorder, single episode, mild<\/td><\/tr>
F32.1<\/td>Major depressive disorder, single episode, moderate<\/td><\/tr>
F32.2<\/td>Major depressive disorder, single episode, severe without psychotic features<\/td><\/tr>
F32.3<\/td>Major depressive disorder, single episode, severe with psychotic features<\/td><\/tr>
F32.4<\/td>Major depressive disorder, single episode, in partial remission<\/td><\/tr>
F32.5<\/td>Major depressive disorder, single episode, in full remission<\/td><\/tr>
F32.9<\/td>Major depressive disorder, single episode, unspecified<\/td><\/tr>
F32.A<\/td>Depression, unspecified<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Major Depressive Disorder, Recurrent<\/h2>\n\n\n\n

For recurrent major depressive disorder, common codes include:<\/p>\n\n\n\n

Code<\/strong><\/td>Description<\/strong><\/td><\/tr>
F33.0<\/td>Major depressive disorder, recurrent, mild<\/td><\/tr>
F33.1<\/td>Major depressive disorder, recurrent, moderate<\/td><\/tr>
F33.2<\/td>Major depressive disorder, recurrent, severe without psychotic features<\/td><\/tr>
F33.3<\/td>Major depressive disorder, recurrent, severe with psychotic features<\/td><\/tr>
F33.40<\/td>Major depressive disorder, recurrent, in remission, unspecified<\/td><\/tr>
F33.41<\/td>Major depressive disorder, recurrent, in partial remission<\/td><\/tr>
F33.42<\/td>Major depressive disorder, recurrent, in full remission<\/td><\/tr>
F33.9<\/td>Major depressive disorder, recurrent, unspecified<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

The note should be very simple in the case of a depression claim. This is whether it is a recurrent episode or a single episode, severity of symptoms, whether the patient is in remission, and the effect of the condition on the individual’s life.<\/p>\n\n\n\n

Anxiety Disorder ICD-10 Codes<\/h2>\n\n\n\n

When coding anxiety, it is best to separate general anxiety symptoms from an anxiety disorder. Many people say that problems occur when F41.9 is used over and over and the provider has provided a more specific diagnosis.<\/p>\n\n\n\n

These anxiety-related diagnoses represent some of the most commonly billed Behavioral health ICD-10 codes in outpatient behavioral health settings.<\/p>\n\n\n\n

Code<\/strong><\/td>Description<\/strong><\/td>When It Fits<\/strong><\/td><\/tr>
F41.1<\/td>Generalized anxiety disorder<\/td>Ongoing excessive anxiety or worry supported by clinical documentation<\/a><\/td><\/tr>
F41.0<\/td>Panic disorder<\/td>Recurrent panic attacks or panic disorder documentation<\/td><\/tr>
F41.3<\/td>Other mixed anxiety disorders<\/td>Mixed anxiety presentation not better captured elsewhere<\/td><\/tr>
F41.8<\/td>Other specified anxiety disorders<\/td>A specified anxiety disorder that does not fit another code<\/td><\/tr>
F41.9<\/td>Anxiety disorder, unspecified<\/td>Anxiety is documented, but the specific disorder is not yet known<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

When the patient is currently undergoing assessment, an unspecified code may be applicable in this case. Otherwise, if there is documentation of GAD, panic disorder, social anxiety disorder, or any other particular disorder, the diagnosis must reflect such.<\/p>\n\n\n\n

PTSD, Stress, and Adjustment Disorder Codes<\/h2>\n\n\n\n

Trauma coding needs careful review. PTSD, acute stress reaction, adjustment disorder, anxiety, depression, and substance use can share similar symptoms.<\/p>\n\n\n\n

Code<\/strong><\/td>Description<\/strong><\/td><\/tr>
F43.0<\/td>Acute stress reaction<\/td><\/tr>
F43.10<\/td>Post-traumatic stress disorder, unspecified<\/td><\/tr>
F43.11<\/td>Post-traumatic stress disorder, acute<\/td><\/tr>
F43.12<\/td>Post-traumatic stress disorder, chronic<\/td><\/tr>
F43.20<\/td>Adjustment disorder, unspecified<\/td><\/tr>
F43.21<\/td>Adjustment disorder with depressed mood<\/td><\/tr>
F43.22<\/td>Adjustment disorder with anxiety<\/td><\/tr>
F43.23<\/td>Adjustment disorder with mixed anxiety and depressed mood<\/td><\/tr>
F43.24<\/td>Adjustment disorder with disturbance of conduct<\/td><\/tr>
F43.25<\/td>Adjustment disorder with mixed disturbance of emotions and conduct<\/td><\/tr>
F43.29<\/td>Adjustment disorder with other symptoms<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Many code lists stop at F43.10 or F43.23. That will facilitate the process of lookup but not necessarily help a biller determine whether a note mentions PTSD, acute stress reaction, or adjustment disorder. Stressor and\/or trauma, symptom pattern (if applicable), duration, clinical impact, stressor\/trauma focus of diagnosis and treatment for more robust billing.<\/p>\n\n\n\n

Bipolar Disorder ICD-10 Codes<\/h2>\n\n\n\n

Bipolar coding should not stop at \u201cbipolar disorder\u201d when the record supports more detail. The current or most recent episode matters. The note should show whether the episode is hypomanic, manic, depressed, mixed, in remission, or unspecified.<\/p>\n\n\n\n

Code<\/strong><\/td>Description<\/strong><\/td><\/tr>
F31.0<\/td>Bipolar disorder, current episode hypomanic<\/td><\/tr>
F31.11<\/td>Bipolar disorder, current episode manic without psychotic features, mild<\/td><\/tr>
F31.12<\/td>Bipolar disorder, current episode manic without psychotic features, moderate<\/td><\/tr>
F31.13<\/td>Bipolar disorder, current episode manic without psychotic features, severe<\/td><\/tr>
F31.2<\/td>Bipolar disorder, current episode manic severe with psychotic features<\/td><\/tr>
F31.31<\/td>Bipolar disorder, current episode depressed, mild<\/td><\/tr>
F31.32<\/td>Bipolar disorder, current episode depressed, moderate<\/td><\/tr>
F31.4<\/td>Bipolar disorder, current episode depressed, severe without psychotic features<\/td><\/tr>
F31.5<\/td>Bipolar disorder, current episode depressed, severe with psychotic features<\/td><\/tr>
F31.9<\/td>Bipolar disorder, unspecified<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Before choosing a bipolar code, review the note for episode type, mood symptoms, severity, psychotic features, remission status, medication management<\/a>, safety concerns, and the reason for the encounter.<\/p>\n\n\n\n

ADHD ICD-10 Codes<\/h2>\n\n\n\n

ADHD codes are common in child, adolescent, and adult behavioral health practices. The coding problem is usually not the diagnosis itself, but the missing presentation type.<\/p>\n\n\n\n

Code<\/strong><\/td>Description<\/strong><\/td><\/tr>
F90.0<\/td>Attention-deficit hyperactivity disorder, predominantly inattentive type<\/td><\/tr>
F90.1<\/td>Attention-deficit hyperactivity disorder, predominantly hyperactive type<\/td><\/tr>
F90.2<\/td>Attention-deficit hyperactivity disorder, combined type<\/td><\/tr>
F90.8<\/td>Attention-deficit hyperactivity disorder, other type<\/td><\/tr>
F90.9<\/td>Attention-deficit hyperactivity disorder, unspecified type<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Documentation for ADHD billing needs to include the ADHD diagnosis, the clinical basis, the impact, the treatment plan, the medication status if applicable, the impact on a child’s school or work, and follow up needs. If assessment tools, history reviewed, collateral information and clinical findings are part of the service, the provider should also document these for evaluations.<\/p>\n\n\n\n

Schizophrenia and Psychotic Disorder Codes<\/h2>\n\n\n\n

Psychotic disorder codes often affect care plans, medication management, higher-acuity services, and payer reviews. These diagnoses are not interchangeable. The note should clearly support the condition being billed.<\/p>\n\n\n\n

Code<\/strong><\/td>Description<\/strong><\/td><\/tr>
F20.0<\/td>Paranoid schizophrenia<\/td><\/tr>
F20.1<\/td>Disorganized schizophrenia<\/td><\/tr>
F20.2<\/td>Catatonic schizophrenia<\/td><\/tr>
F20.3<\/td>Undifferentiated schizophrenia<\/td><\/tr>
F20.5<\/td>Residual schizophrenia<\/td><\/tr>
F20.9<\/td>Schizophrenia, unspecified<\/td><\/tr>
F25.0<\/td>Schizoaffective disorder, bipolar type<\/td><\/tr>
F25.1<\/td>Schizoaffective disorder, depressive type<\/td><\/tr>
F25.9<\/td>Schizoaffective disorder, unspecified<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Substance Use Disorder ICD-10 Codes<\/h2>\n\n\n\n

Substance use codes require caution because, with the ICD-10-CM<\/a>, there is a hierarchical order of use, abuse, and dependence codes. In cases where use, abuse, and dependence are documented for the same substance, only one code is to be used. CMS states that abuse takes priority over use, and dependence takes priority over abuse or use when both are documented.<\/p>\n\n\n\n

The remission rule is also important. For substance use categories F10\u2013F19, \u201cin remission\u201d codes require the provider\u2019s clinical judgment and must be assigned based on provider documentation unless the classification gives another instruction. <\/p>\n\n\n\n

Mild substance use disorders in remission are classified to abuse-in-remission codes, while moderate or severe substance use disorders in remission are classified to dependence-in-remission codes.<\/p>\n\n\n\n

Substance Group<\/strong><\/td>Common Code Examples<\/strong><\/td>Documentation Needed<\/strong><\/td><\/tr>
Alcohol-related disorders<\/td>F10.10, F10.20, F10.21<\/td>Use, abuse, dependence, remission, intoxication, withdrawal, or complications<\/td><\/tr>
Opioid-related disorders<\/td>F11.10, F11.20, F11.21<\/td>Severity, remission, medication treatment, withdrawal, intoxication, or complications<\/td><\/tr>
Cannabis-related disorders<\/td>F12.10, F12.20, F12.21<\/td>Pattern of use, dependence, remission, and associated disorder<\/td><\/tr>
Sedative, hypnotic, or anxiolytic disorders<\/td>F13.10, F13.20, F13.21<\/td>Substance class, dependence, withdrawal risk, remission<\/td><\/tr>
Cocaine-related disorders<\/td>F14.10, F14.20, F14.21<\/td>Use pattern, dependence, remission, intoxication, or complications<\/td><\/tr>
Other stimulant-related disorders<\/td>F15.10, F15.20, F15.21<\/td>Substance type, severity, remission, and related mental health effects<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Unspecified psychoactive substance use codes should not be used casually. CMS states that unspecified psychoactive substance use codes should be assigned only when provider documentation supports them and when they meet the definition of a reportable diagnosis.<\/p>\n\n\n\n

Eating Disorder ICD-10 Codes<\/h2>\n\n\n\n

Eating disorder coding has become more specific in recent code sets, so older cheat sheets may not be enough. For 2026 billing, practices should verify whether severity-specific codes are available and supported in the medical record.<\/p>\n\n\n\n

Condition<\/strong><\/td>Coding Guidance<\/strong><\/td><\/tr>
Eating disorders<\/td>Use the current F50.-<\/strong> code structure that matches the provider’s documented diagnosis, severity, remission status, and other required clinical details. Because ICD-10-CM code options may change with annual updates, verify the exact billable code in the applicable FY 2026 ICD-10-CM Tabular List before claim submission.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

The CDC\/NCHS FY26 April 1, 2026 files include official code descriptions and code-set materials, which should be used as the source of truth when confirming valid codes for current billing.<\/p>\n\n\n\n

ICD-10 and CPT Codes: How They Work Together<\/h2>\n\n\n\n

A mental health claim<\/a> usually requires both diagnosis and procedure coding. While ICD-10-CM identifies why the patient received care, CPT and HCPCS represent the service performed. Together, these behavioral health billing codes support medical necessity and reimbursement.<\/p>\n\n\n\n

CPT \/ HCPCS Code<\/strong><\/td>Common Use<\/strong><\/td>Documentation Note<\/strong><\/td><\/tr>
90791<\/td>Psychiatric diagnostic evaluation<\/td>Document history, presenting problems, mental status, diagnosis or clinical impression, risk, and treatment need.<\/td><\/tr>
90792<\/td>Psychiatric diagnostic evaluation with medical services<\/a><\/td>Document assessment, medical services, medication-related findings when relevant, and treatment plan.<\/td><\/tr>
90832<\/td>Psychotherapy, 30 minutes<\/td>CMS lists 16\u201337 minutes. Document start\/stop time or total time.<\/td><\/tr>
90834<\/td>Psychotherapy, 45 minutes<\/td>CMS lists 38\u201352 minutes. Document start\/stop time or total time.<\/td><\/tr>
90837<\/td>Psychotherapy, 60 minutes<\/td>CMS lists 53 minutes or more. Document time and medical necessity.<\/td><\/tr>
90833<\/td>Psychotherapy add-on with E\/M<\/td>Document psychotherapy time and E\/M work separately.<\/td><\/tr>
90836<\/td>Psychotherapy add-on with E\/M<\/td>Document psychotherapy time and E\/M work separately.<\/td><\/tr>
90838<\/td>Psychotherapy add-on with E\/M<\/td>Document psychotherapy time and clinical need.<\/td><\/tr>
90853<\/td>Group psychotherapy<\/td>Document group service, patient participation, treatment focus, and progress.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

The ICD-10-CM diagnosis still needs to support why the patient received the service. For example, F41.1 may support a generalized anxiety disorder visit, while 90834 describes a 45-minute psychotherapy session<\/a>. <\/p>\n\n\n\n

Common ICD-10 Coding Mistakes in Mental Health Billing<\/h2>\n\n\n\n

1. Using unspecified codes when the note supports a specific diagnosis<\/h3>\n\n\n\n

Unspecified codes are not always wrong, but they should reflect what is truly known at the encounter. If the provider documents generalized anxiety disorder, recurrent major depressive disorder, or chronic PTSD, the billing code should not stay vague.<\/p>\n\n\n\n

2. Coding a suspected diagnosis in outpatient care<\/h3>\n\n\n\n

In outpatient coding, do not code diagnoses described only as probable, suspected, questionable, rule out, compatible with, consistent with, or working diagnosis. Code the condition to the highest degree of certainty known at the visit.<\/p>\n\n\n\n

3. Billing category headers instead of complete codes<\/h3>\n\n\n\n

A three-character code is valid only when it is not further subdivided. If more characters are required, the code is invalid unless reported to the full required length.<\/p>\n\n\n\n

4. Ignoring substance use hierarchy<\/h3>\n\n\n\n

If the same substance is documented as use, abuse, and dependence, dependence is coded rather than reporting multiple pattern codes for the same substance.<\/p>\n\n\n\n

5. Letting diagnosis and treatment plan drift apart<\/h3>\n\n\n\n

If the treatment plan focuses on panic attacks, trauma symptoms, or recurrent depression, the diagnosis section should support that focus. Diagnosis, assessment, plan, and claim should tell the same story.<\/p>\n\n\n\n

Billing Examples<\/h2>\n\n\n\n

Anxiety Intake<\/h3>\n\n\n\n

A new patient reports constant worry, poor sleep, and trouble focusing. The provider documents anxiety but has not confirmed generalized anxiety disorder.<\/p>\n\n\n\n

Better coding choice: F41.9 may be appropriate if anxiety disorder is documented but not yet specified.<\/p>\n\n\n\n

Avoid: F41.1 unless the note supports generalized anxiety disorder.<\/p>\n\n\n\n

Depression Follow-Up<\/h3>\n\n\n\n

The note documents recurrent major depressive disorder, moderate, with ongoing symptoms.<\/p>\n\n\n\n

Better coding choice: F33.1<\/p>\n\n\n\n

Avoid: F32.A or F33.9 when the note clearly supports recurrent moderate MDD.<\/p>\n\n\n\n

Rule-Out PTSD<\/h3>\n\n\n\n

The provider writes \u201crule out PTSD\u201d and documents nightmares, avoidance, and trauma history.<\/p>\n\n\n\n

Better coding choice: Code the symptoms or highest confirmed condition for that outpatient visit.<\/p>\n\n\n\n

Avoid: F43.10 unless PTSD is documented as confirmed.<\/p>\n\n\n\n

Coexisting Conditions<\/h3>\n\n\n\n

The session focuses on panic attacks, but the patient also has a history of depression that is not assessed or treated that day.<\/p>\n\n\n\n

Better coding choice: List the panic-related diagnosis first when supported.<\/p>\n\n\n\n

Avoid: automatically listing every past diagnosis if it does not affect care during the visit.<\/p>\n\n\n\n
