Behavioral and Mental Health Billing // 2026 Field Guide

Medicare now pays MFTs and mental health counselors. Here is how to actually get paid.

Short answer: since January 1, 2024, marriage-and-family therapists (MFTs) and mental health counselors (MHCs) enroll in Medicare and bill under their own NPI, at 75% of the clinical psychologist fee schedule amount. The money is real. The denials are almost always self-inflicted, and they come from one place: billing these therapists the old incident-to way instead of the new direct-enrollment way.

Payable since Jan 1, 2024 Rate: 75% of psychologist PFS Authority: CAA 2023 §4121 Enrollment: CMS-855I + 855R

The one-paragraph version

What changed, in plain operator language

The Consolidated Appropriations Act, 2023 created two brand-new Medicare benefit categories under Section 1861(lll) of the Social Security Act: one for marriage-and-family therapists and one for mental health counselors (a definition that also sweeps in qualifying addiction and substance-use-disorder counselors who meet the master's, licensure, and experience bar). CMS turned that statute into a working benefit through the CY2024 Physician Fee Schedule Final Rule (CMS-1784-F). As of the first day of 2024, these clinicians stopped being invisible to Medicare and became enrolled, billing providers in their own right.

That is the good news you can build a service line on. The catch is that most practices already had these therapists on staff, billing their work indirectly through a physician or psychologist. The change from indirect to direct is exactly where the 2026 denials live.

The numbers that matter

Five facts to anchor your workflow

2024First calendar year MFT and MHC services are payable by Medicare, per CMS-1784-F.

75%Statutory payment rate: 75% of the amount a clinical psychologist would be paid for the same service.

2New benefit categories and distinct Medicare enrollment specialties (MFT and MHC).

3New digital mental health treatment G-codes: G0552, G0553, G0554 (CY2025 PFS).

2.5%Statutory update folded into the CY2026 PFS conversion factor under the 2025 budget law.

An enrolled therapist billing under their own NPI is a clean claim. The same therapist billed incident-to a physician is a refund waiting to happen.

How we got here

The policy timeline, so you know which rule governs which claim

2023

Consolidated Appropriations Act, 2023

Section 4121 amends the Social Security Act to add MFT and MHC as covered Medicare practitioners under §1861(lll), effective for services on or after January 1, 2024.

CY2024 PFS

CMS-1784-F operationalizes it

CMS opens enrollment, sets payment at 75% of the psychologist rate, and finalizes general (not direct) supervision for behavioral health services furnished incident-to.

CY2025 PFS

CMS-1807-F expands the toolkit

New digital mental health treatment codes (G0552-G0554), safety-planning and post-discharge follow-up services, and broader behavioral health integration all become billable by these practitioners.

CY2026 PFS

The current rulebook

The CY2026 Physician Fee Schedule Final Rule carries a 2.5% statutory conversion-factor update, keeps the permanent behavioral health telehealth benefit (including the home as an originating site and audio-only), and holds the MFT and MHC provisions in place.

The enrollment walkthrough

Enrolling a newly eligible therapist, step by step

This is the part teams overthink. It is the same PECOS path every other individual practitioner uses. The only new decisions are the specialty and the taxonomy.

Fix the NPI first

In NPPES, confirm the individual NPI carries the right taxonomy: MFT 106H00000X or mental health counselor 101YM0800X. A stale taxonomy misroutes the whole enrollment.

File the CMS-855I

Individual enrollment in PECOS. Select the MFT or MHC specialty and an effective date on or after Jan 1, 2024. This is the record that makes the therapist a billing provider.

File the CMS-855R

Reassign benefits to the group TIN. No 855R on file means the group cannot legally collect the therapist's payments. This is the single most common gap.

Confirm, then bill

Wait for the MAC approval and effective date, verify the reassignment shows active in PECOS, then submit under the therapist's own NPI as rendering provider.

The therapist who did the work is the therapist on the claim. Every shortcut around that rule is a takeback.

// Rendering-provider integrity, the short version

The traps that still deny

Incident-to and supervision, where the money leaks

Now that MFTs and MHCs have their own benefit category, the old habits actively cause denials and post-payment recoupments. Here is the map from the wrong move to the right one.

The move	Why it denies or recoups	Do this instead
Billing the therapy visit incident-to a physician at 100%	Since Jan 1, 2024 these clinicians have their own benefit category and NPI, so their covered services are no longer physician incident-to services.	Enroll the therapist and bill under their NPI at the 75% rate.
Assuming direct supervision for incident-to auxiliary staff	Teams still staff supervision the old way and document the wrong standard.	Use the general-supervision standard CMS finalized for behavioral health, with an enrolled, eligible supervisor documented.
Group billing without a CMS-855R on file	Benefits were never reassigned to the TIN, so the group has no right to the payment.	File the 855R and confirm it is active before the first claim date.
Putting a psychologist or LCSW as billing provider for a session the MFT or MHC rendered	Rendering-provider mismatch, a program-integrity flag, not a coding nicety.	Bill under the actual treating therapist, full stop.
Leaving an old specialty or taxonomy on the 855I	Enrollment is rejected or routed to the wrong benefit, and clean claims bounce.	Match the MFT or MHC specialty to the NPPES taxonomy exactly.

New revenue you can attach

Digital mental health treatment coding

The CY2025 Physician Fee Schedule Final Rule (CMS-1807-F) created three HCPCS codes for furnishing FDA-cleared digital mental health treatment (DMHT) devices as an adjunct to an ongoing behavioral health treatment plan. MFTs and MHCs can bill these when the device supports the care they are already delivering.

G0552

Supply of the FDA-cleared digital mental health treatment device, plus initial patient education and onboarding. Billed at the start of the course of treatment.

G0553

Monthly treatment-management services tied to the DMHT device, first 20 minutes of clinician time in a calendar month.

G0554

Each additional 20 minutes of DMHT treatment-management time in the same month, reported with G0553.

Guardrails: the device must be FDA-cleared, the codes are adjunctive to an active behavioral health treatment plan, and the same clinician cannot double-count time already billed under another management service. Also worth adding to the same enrolled-therapist workflow: Collaborative Care (CPT 99492, 99493, 99494 and G2214) and general behavioral health integration, where an enrolled MFT or MHC can serve as the behavioral health care manager.

Turn a new benefit category into clean, paid claims

Standing up MFT and MHC billing is not hard, but the transition from incident-to to direct enrollment is where practices quietly lose money for months. Our behavioral and mental health billing team runs the full path: PECOS enrollment and 855R reassignment, specialty and taxonomy alignment, incident-to and supervision compliance, and the coding to attach digital mental health treatment and collaborative care once your therapists are live. You bring the clinicians. We make sure Medicare pays for them the first time.
