What the Diagnostic Privilege Actually Does
A standard LMHC license does not include diagnosis on its own. The diagnostic privilege is the credential that adds it: an add-on scope-of-practice authorization, not a separate license, that lets an already-licensed LMHC diagnose mental, emotional, behavioral, developmental and addictive disorders (Educ. Law 8401-a; 8 NYCRR 79-9.6). It sits on top of the LMHC license covered in New York LMHC requirements, not in place of it.
The law took effect June 24, 2024. NYSED processes it through its own set of forms, Forms 1D, 2D, 4D, 5D and 5CS-D, separate from the standard LMHC application forms and separate from Form 4B, which verifies the 3,000-hour supervised experience for the LMHC license itself, not the diagnostic privilege's hours.
Who Qualifies, and What It Costs
Four things have to be true before NYSED grants the privilege: you are already licensed and registered as an LMHC; your master's degree runs at least 60 semester hours and includes at least 12 semester hours of clinical coursework; you have completed 2,000 hours of supervised, direct client contact covering diagnosis, psychotherapy and assessment-based treatment planning; and you pay the $175 fee (Educ. Law 8401-a(1)(c),(e)).
| Item | Amount | Cite |
|---|---|---|
| Initial diagnostic privilege fee | $175 | Educ. Law 8401-a(1)(e) |
| Ongoing, per registration period | $175 | Educ. Law 8401-a(3) |
| Diagnostic limited permit | $70 | Educ. Law 8409(3) |
The $175 ongoing fee is not a separate renewal cycle to track. It registers alongside your regular triennial LMHC registration, so it lands on the same clock and the same paperwork as the license you already have.
How Long the Privilege Lasts
Once NYSED issues it, the diagnostic privilege is valid for the life of the holder unless it is revoked or suspended (Educ. Law 8401-a). It does not carry its own expiration date the way a limited permit does. You still pay the $175 fee every time you re-register your LMHC license, but that is a registration cost, not a countdown on the privilege itself.
If You're Still on the Limited Permit
The diagnostic privilege requires already being licensed and registered as an LMHC (Educ. Law 8401-a(1)). If you are still on the LMHC limited permit, you are working toward that first license, not the diagnostic privilege yet.
Treat the 2,000 hours as an additional, post-licensure credential layered on top of the license you are currently pursuing, not as something the limited permit period earns for you automatically. NYSED's statute does not describe the permit period as a source of credit toward the 2,000 hours, so plan for the diagnostic privilege as a separate project that starts once your LMHC license is issued.
The Grandfather Path for Already-Licensed LMHCs
An LMHC licensed before the law took effect may skip the 2,000-hour requirement by submitting a supervisor's attestation of at least 3 years of relevant direct-client-contact experience (Educ. Law 8401-a). The window to use this path is fixed, not open-ended.
| Date | What Happens | Cite |
|---|---|---|
| June 24, 2024 | Diagnostic privilege takes effect; grandfather eligibility is fixed to licensure before this date | Educ. Law 8401-a |
| June 24, 2024 to June 24, 2027 | 3-year window to apply under the grandfather path with a supervisor attestation of 3+ years | Educ. Law 8401-a |
| June 24, 2027 | Grandfather window closes; the transitional provision 8410(11) is repealed the same day | Educ. Law 8401-a; 8410(11) |
The grandfather deadline is June 24, 2027, not a rolling 3 years from your license date. It is fixed to the law's effective date. After that date, the grandfather path is no longer available.
The Same Privilege Exists for LMFTs
Education Law 8401-a is not LMHC-only. An already-licensed LMFT can apply for the same diagnostic privilege, under the LMFT-specific regulation at 8 NYCRR 79-10.6, with the same 2,000-hour requirement, the same $175 initial and ongoing fees, and the same grandfather path and June 24, 2027 deadline for anyone licensed before June 24, 2024.
How This Differs From LCSW-R
LCSW-R sounds similar but is a different mechanism in a different profession. It was an insurance-reimbursement privilege for LCSWs, not LMHCs, and NYSED stopped accepting new applications for it effective January 1, 2023, after Chapter 818 of the Laws of 2022 removed the requirement from the Insurance Law. See what LCSW-R means for the full picture.
The LMHC and LMFT diagnostic privilege is the opposite situation: current, active, and open to new applicants under Education Law 8401-a. Do not confuse the two. The diagnostic privilege covers LMHCs, LMFTs and psychoanalysts; the R privilege was a social work credential.
Is "LMHC-D" an Official Title?
No. It is a shorthand some practitioners and search queries use, but NYSED's statute and regulations never create or use an "LMHC-D" title. The agency's own name for the credential is the "diagnostic privilege" (Educ. Law 8401-a; 8 NYCRR 79-9.6). If you see "LMHC-D" on a business card or a directory listing, it is shorthand, not a title created by the statute or regulations.
What the 2025 Numbers Show
NYSED issued 1,768 new LMHC licenses in 2025, up from 1,212 in 2024. That increase lines up in time with the diagnostic privilege taking effect in June 2024, but NYSED does not publish a stated cause for the jump. Read the two facts side by side, not as one causing the other.

FAQ: The LMHC Diagnostic Privilege in New York
Can an LMHC diagnose in New York?▾
Yes. An already-licensed LMHC can diagnose mental, emotional, behavioral, developmental and addictive disorders in New York under the diagnostic privilege created by Education Law 8401-a, effective June 24, 2024, and its regulations at 8 NYCRR 79-9.6. Without the privilege, a licensed mental health counselor's scope does not include diagnosis. The privilege is an add-on credential, not a separate license.
What does an LMHC need to get the diagnostic privilege?▾
An LMHC already licensed and registered in New York; a 60-semester-hour master's (or higher) including at least 12 semester hours of clinical coursework; 2,000 hours of supervised, direct client contact covering diagnosis, psychotherapy and assessment-based treatment planning; and a $175 fee (Educ. Law 8401-a(1)(c),(e)). The grandfather path below waives the 2,000 hours for practitioners already licensed before June 24, 2024.
How much does the LMHC diagnostic privilege cost?▾
The initial fee is $175 (Educ. Law 8401-a(1)(e)). After that, it registers alongside your regular triennial LMHC registration at $175 per registration period (Educ. Law 8401-a(3)). NYSED also lists a $70 diagnostic limited permit, the same fee charged for a standard limited permit (Educ. Law 8409(3)).
How long does the diagnostic privilege last?▾
Once issued, it is valid for the life of the holder unless it is revoked or suspended (Educ. Law 8401-a). You still pay the $175 registration fee each triennial period alongside your regular LMHC registration, but the privilege itself does not expire on its own schedule.
What is the grandfather path for the LMHC diagnostic privilege?▾
An LMHC licensed before June 24, 2024 can skip the 2,000-hour requirement by submitting a supervisor's attestation of at least 3 years of relevant direct-client-contact experience. The application has to be filed within 3 years of the law's effective date, by June 24, 2027 (Educ. Law 8401-a). A related transitional provision, Educ. Law 8410(11), is also repealed on that same date.
Is 'LMHC-D' an official title in New York?▾
No. Searchers and some practitioners use "LMHC-D" as shorthand, but NYSED's statute and regulations never use that abbreviation. The agency's own term is "diagnostic privilege" (Educ. Law 8401-a; 8 NYCRR 79-9.6). Treat "LMHC-D" as informal shorthand, not a credential NYSED issues or recognizes by that name.
Can someone on an LMHC limited permit get the diagnostic privilege?▾
Not yet. The diagnostic privilege requires already being licensed and registered as an LMHC (Educ. Law 8401-a(1)). A limited permit holder is still working toward that first license, so the 2,000 supervised hours for the diagnostic privilege sit on top of full licensure, as a separate, later credential rather than something a permit period earns automatically.
