Short answer

Thrizer supports many ICD-10 diagnosis codes commonly used in behavioral health and related out-of-network claim workflows. If a diagnosis code is supported in Thrizer, that means it can be used in Thrizer workflows where a diagnosis code is required, such as clinician client setup, claim submission, or claim documentation. It does not mean the diagnosis is clinically correct, that the client’s insurance plan will cover the service, or that the claim will be approved or reimbursed. The clinician is responsible for selecting the diagnosis code that accurately reflects the client’s clinical care. The insurance carrier determines whether a submitted claim is accepted, denied, applied to deductible, or reimbursed.

How diagnosis codes work in Thrizer

A diagnosis code helps describe the clinical reason for the service on an insurance claim. For a charge to be submitted as a claim through Thrizer, the claim generally needs:
  • a diagnosis code
  • a CPT code structure
  • provider information, including a valid NPI
  • service date and appointment details
  • billed amount
  • client insurance information
For OON Pay and Thrizer Pay, claim submission is tied to a successful charge. If the charge does not process successfully, the claim is not submitted.
Diagnosis code support means the code can be used in Thrizer workflows. It is not clinical coding advice and does not guarantee insurance coverage, claim approval, deductible application, or reimbursement.

Common diagnosis codes clinicians ask about

These are diagnosis codes clinicians commonly ask about. Inclusion here is for orientation only — it is not clinical advice and does not indicate that the code will be accepted by any insurer or covered for a specific service.

Supported diagnosis-code families

Thrizer supports many diagnosis codes across behavioral health ICD-10 F-code ranges, along with selected Z-codes that may appear in clinical or administrative workflows.
Code familyExamples of included categories
F01–F09Dementia, delirium, and mental disorders due to known physiological conditions
F10–F19Substance-related disorders
F20–F29Schizophrenia spectrum and other psychotic disorders
F30–F39Mood disorders, including bipolar and depressive disorders

F90–F99ADHD, conduct, tic, childhood, adolescent, and unspecified mental disorders
Z-codesSelected relationship, counseling, history, and contextual factors
Do not assume that every possible ICD-10 code in a family is supported. If you need to confirm a specific code, check the code in Thrizer or contact support.

If the diagnosis code is not listed here

A diagnosis code may still be usable even if it is not shown in the common-code table above. If you cannot find the diagnosis code you need, contact Thrizer support with:
  • the diagnosis code
  • the diagnosis description
  • the client or account context, if relevant
  • whether the issue is occurring during client setup, charging, or claim submission
Thrizer can review whether the code is supported for workflow use.

What diagnosis-code support does not mean

Diagnosis-code support in Thrizer does not mean:
  • the diagnosis is clinically correct for the client
  • the diagnosis should be used for a specific service
  • the client’s plan covers services for that diagnosis
  • the diagnosis establishes medical necessity
  • the claim will be approved
  • the claim will be reimbursed
  • the amount will apply to deductible
  • the insurer will accept the diagnosis for a specific CPT code
Those decisions depend on the clinician’s clinical judgment, documentation, the client’s insurance plan, and the insurance carrier’s claim-processing rules.

When to wait before charging

If no diagnosis has been assigned yet, wait until the diagnosis is available before submitting a claim through an insurance workflow. Claims require diagnosis information. Submitting incomplete claim information can cause claim issues or prevent claim submission.

What to avoid

Avoid choosing a diagnosis code only because it appears more likely to reimburse. Avoid using a diagnosis code that does not accurately reflect the client’s clinical care. Avoid treating diagnosis-code support as confirmation that the insurance carrier will accept the claim. Avoid submitting an insurance claim before the diagnosis, CPT code, provider, and charge details are complete.

If you can’t find a diagnosis code

Thrizer’s supported diagnosis-code workflow covers the behavioral health ICD-10 F-code ranges (F01–F99) along with selected Z-codes that commonly appear in out-of-network mental health claims. If a specific code does not work in your portal or you are unsure whether it is supported, contact support with the code, description, and where you encountered the issue. Support can confirm whether it is supported in Thrizer’s workflow. Support for a code in Thrizer’s workflow is not a statement that the insurance carrier will accept or reimburse a claim using that code.
