If you own or operate a mental health counseling business and need your NAICS code, here is your answer right away.
The primary NAICS code for a mental health counselor is 621330, classified under Offices of Mental Health Practitioners (except Physicians) in the Health Care and Social Assistance sector. However, “mental health counseling” can be provided in several different settings. The right code for your business depends on whether you operate a private practice, work in a group clinic, or provide non-clinical crisis support. This page covers the relevant codes so you can identify the one that fits.

What Does NAICS Code 621330 Cover?
According to the official 2022 NAICS data, code 621330 covers establishments primarily engaged in the outpatient care of mental health patients by licensed health practitioners who are not physicians.
In simple terms, this code applies to independent private practices or small group practices where licensed clinicians provide direct therapy to clients. For mental health counselors, this includes:
- Licensed Professional Counselors (LPCs) providing psychotherapy
- Marriage and Family Therapists (MFTs)
- Clinical Social Workers (LCSWs) offering mental health counseling
- Psychologists (PhD or PsyD) providing talk therapy and psychological testing
- Practices specializing in anxiety, depression, trauma, PTSD, or grief counseling
The important distinction here is clinical mental health treatment. This code covers licensed professionals diagnosing and treating mental, emotional, and behavioral health conditions, but it specifically excludes medical doctors who can prescribe psychiatric medications.
Does My Mental Health Counseling Business Qualify for Code 621330?
Your business qualifies for NAICS code 621330 if:
- You operate a private practice as a licensed mental health professional (LPC, LCSW, MFT, or Psychologist)
- Your main source of revenue comes from providing direct clinical therapy or counseling sessions
- You treat diagnosed mental health conditions
Your business may not qualify if:
- You work in a larger outpatient mental health center or clinic facility that employs a multi-disciplinary team of medical and counseling staff under one roof, which falls under 621420 (Outpatient Mental Health and Substance Abuse Centers) instead
- You provide non-clinical community support, run a crisis hotline, or offer telephone/text-based crisis counseling without a direct clinical therapy model, which falls under 624190 (Other Individual and Family Services) instead
- You are a psychiatrist (MD or DO) who primarily prescribes medication rather than providing talk therapy, which falls under 621111 (Offices of Physicians, Mental Health Specialists) instead
When your business sits between two codes, always classify based on whichever activity generates the most revenue.
Where Will You Need This Code?
Your NAICS code appears in more places than most private practice owners expect. Here is where code 621330 will be required:
- Insurance Credentialing. This is highly critical for counselors. When you apply to be an in-network provider for insurance panels (like Blue Cross, Aetna, Cigna, or UnitedHealthcare), the insurance company requires your NAICS code to verify that you are a legitimate clinical healthcare provider operating under the correct tax and medical classification.
- Professional Liability Insurance. Insurance providers use your NAICS code to calculate your Professional Liability (Malpractice) and General Liability premium rates. Mental health practitioners carry unique risks (such as claims of improper therapeutic boundaries or negligence in suicide prevention), and your code ensures you get the right malpractice coverage.
- Telehealth Platform Verification. If you host your practice on third-party telehealth platforms or EHR systems (like SimplePractice, BetterHelp, or Headway), they require your NAICS code during the business verification process to ensure HIPAA compliance.
- Business Registration. Most state and local business registration portals ask for your NAICS code when you set up a professional LLC or PLLC for your counseling practice.
- Tax Filings (Schedule C). When you file your taxes as a sole proprietor or single-member LLC, the IRS requires a NAICS code on your Schedule C to classify your practice’s income and expenses.
- Business Bank Accounts. Many banks ask for your NAICS code when opening a business checking account to ensure your business is classified properly from day one.

Frequently Asked Questions
What is the NAICS code for a mental health clinic with multiple counselors?
If you operate a facility where multiple counselors, therapists, and potentially psychiatrists work together under a single corporate entity or clinic umbrella, your correct code is 621420 (Outpatient Mental Health and Substance Abuse Centers). Code 621330 is primarily for solo practitioners or small independent group practices.
What is the NAICS code for a crisis hotline or suicide prevention text line?
If your organization provides non-medical crisis intervention, community support, or suicide prevention hotlines rather than ongoing, scheduled clinical therapy sessions, your correct classification is 624190 (Other Individual and Family Services).
Does code 621330 cover life coaching or career counseling?
No. A life coach, success coach, or career counselor working with clients on personal or career development generally falls under 624190 (Other Individual and Family Services) or 812990 (All Other Personal Services). Code 621330 is strictly for licensed clinical mental health professionals diagnosing and treating psychological conditions.
Are clinical social workers (LCSWs) classified under 621330?
Yes. As long as your primary business activity is providing psychotherapy, clinical assessments, or mental health counseling (rather than acting as a case manager connecting people to community resources), your private practice falls under 621330.
