How to use this ICD-10 lookup

Selecting the right ICD-10-CM diagnosis code supports clean claims and medical-necessity documentation. This lookup covers the mental and behavioral health codes therapists use most, including mood, anxiety, trauma, substance use, neurocognitive, child and adolescent, and the psychosocial Z codes that often accompany a diagnosis.

Everything runs in your browser and nothing is uploaded or stored. Search by code number (e.g., F41.1 or F32.1) or by a plain-language term like depression, PTSD, ADHD, or panic attack. Each result links to a full guide showing the official description, whether it is a billable leaf code, and a clinical note.

Use it for situations like

  • Confirming the most specific code for a depressive or anxiety presentation before billing.
  • Checking whether a code like F32 is a category you must specify further.
  • Finding the right screening Z code (e.g., Z13.31 for depression screening) to pair with an assessment.
  • Looking up substance use, eating disorder, or child and adolescent codes quickly during documentation.

FAQ

Questions therapists ask before using this calculator

What is an ICD-10 code and why do therapists need it?

ICD-10-CM (International Classification of Diseases, Tenth Revision, Clinical Modification) is the diagnosis code set required on claims in the United States. Therapists use it to report the mental or behavioral health diagnosis that justifies the service billed, and payers use it to confirm medical necessity for psychotherapy, assessment, and other behavioral health services.

What is the difference between a billable code and one I should specify further?

A billable code is a leaf code valid for submission on a claim. A category code (often a three-character code such as F32) is a parent grouping that must be specified to a more detailed code before it can be billed. The lookup flags each entry as billable or as a code to specify further so you can choose the most specific supported diagnosis.

Which ICD-10 codes are used most often in mental health practices?

Common examples include F41.1 (generalized anxiety disorder), F33.1 (recurrent major depression, moderate), F90.2 (ADHD, combined presentation), F43.10 (PTSD), F31.81 (bipolar II), and F50.22 (bulimia nervosa, moderate). Screening encounters often use Z13.31 (depression screening) alongside assessment CPT codes.

Should I use an unspecified code like F32.9 or F41.9?

Unspecified codes are valid for billing but are discouraged when documentation supports greater specificity, because payers increasingly request the most specific code available. Whenever you can document severity, episode type, or features, use the more specific code (for example F32.1 instead of F32.9) to reduce denials and audits.

Does each code have its own page?

Yes. Selecting any code opens a dedicated guide with the official descriptor, billing status, when-to-use guidance, documentation tips, common pitfalls, related codes, and FAQs. This makes it easy to reference or share a single diagnosis code.

Is this ICD-10 lookup a substitute for clinical or coding advice?

No. It is a quick reference for clinicians. Code set versions and payer policies change over time, so confirm the current official ICD-10-CM descriptor against the CDC and each payer’s requirements before submitting a claim.
