Telehealth Medicare Billing for Therapy & Mental Health: The Definitive 2026 Guide

If you're a therapist, LCSW, LPC, LMFT, or psychiatrist billing Medicare for telehealth services in 2026, you already know the rules have been changing faster than most providers can keep up with. What was a COVID-era "temporary flexibility" has now evolved into a more permanent (though still evolving) framework — and the cost of not keeping up is real: claim denials, recoupments, and audit exposure.

This guide cuts through the noise. We'll cover every CPT code you need, the current Medicare reimbursement rates, modifier requirements, documentation standards, and the most common billing mistakes that put practices at risk. Whether you're a solo practitioner or managing a group behavioral health practice, consider this your go-to reference for Medicare telehealth billing in 2026.

Why 2026 Is a Pivotal Year for Medicare Telehealth Mental Health Billing

The landscape shifted significantly after Congress passed the Consolidated Appropriations Act of 2023, which extended many telehealth flexibilities through December 31, 2026. That means the countdown is on — and what happens after that date remains uncertain.

Here's what that means practically:

Geographic restrictions remain lifted. Medicare beneficiaries can still receive telehealth mental health services from their home, regardless of whether they live in a rural or urban area.
Audio-only telehealth remains available under specific conditions (more on that below).
In-person visit requirements for mental health telehealth were re-evaluated — and while CMS finalized a policy requiring an in-person visit within 6 months of initiating mental health telehealth services, enforcement nuances matter.
FQHC and RHC billing for telehealth mental health services continues under specific all-inclusive rates.

The bottom line: 2026 is the last year of extended certainty. Practices that build clean, defensible billing and documentation systems now will be far better positioned — regardless of what Congress does next.

Who Can Bill Medicare for Telehealth Mental Health Services?

Not every provider type is created equal under Medicare's telehealth rules. Here's a quick breakdown:

Provider Type	Can Bill Medicare Telehealth?	Notes
Psychiatrists (MD/DO)	✅ Yes	Bill under Part B, physician fee schedule
Clinical Psychologists (PhD/PsyD)	✅ Yes	Cannot bill E/M codes, use psychological testing + psychotherapy codes
Licensed Clinical Social Workers (LCSWs)	✅ Yes	Independent billing under Part B
Licensed Professional Counselors (LPCs)	✅ Yes (as of Jan 1, 2024)	Permanently added as Medicare providers
Licensed Marriage & Family Therapists (LMFTs)	✅ Yes (as of Jan 1, 2024)	Permanently added as Medicare providers
Registered Nurses / NPs (Psychiatric)	✅ Yes	Bill under applicable fee schedule
Interns / Unlicensed Associates	❌ No	Must be independently licensed

Important note for LPCs and LMFTs: While these provider types were permanently added to Medicare in 2024, billing for telehealth specifically still requires meeting all standard telehealth requirements. Don't assume your enrollment is complete just because you can bill in-person — verify your Medicare enrollment includes telehealth billing rights.

The Core CPT Codes for Medicare Telehealth Mental Health Billing in 2026

Psychotherapy Codes (Most Commonly Used)

These are the workhorses of outpatient mental health billing:

CPT Code	Service Description	Time	2026 Medicare Rate (Approx.)
90832	Individual psychotherapy	16–37 min	~$82
90834	Individual psychotherapy	38–52 min	~$111
90837	Individual psychotherapy	53+ min	~$152
90847	Family psychotherapy (with patient)	50 min	~$118
90846	Family psychotherapy (without patient)	50 min	~$107
90853	Group psychotherapy	Per session	~$30
90839	Psychotherapy for crisis, initial 30–74 min	30–74 min	~$202
90840	Psychotherapy for crisis, each additional 30 min	+30 min	~$104

Note: Medicare reimbursement rates vary by geographic locality. The figures above are national averages based on the 2025 physician fee schedule; 2026 rates are subject to the annual conversion factor update from CMS, typically announced in the November Final Rule.

Add-On Codes (Psychotherapy with E/M)

For psychiatric providers (MDs, DOs, NPs, PAs) who combine a medical evaluation with psychotherapy:

CPT Code	Description	Add-on to:
90833	Psychotherapy add-on, 16–37 min	E/M code (99202–99215)
90836	Psychotherapy add-on, 38–52 min	E/M code
90838	Psychotherapy add-on, 53+ min	E/M code

These add-on codes are not standalone — they must always be billed alongside a primary E/M service code. LCSWs, LPCs, and LMFTs cannot bill these; they are restricted to psychiatrists, physicians, and advanced practice providers with prescribing authority.

Psychiatric Diagnostic Evaluation Codes

CPT Code	Description	2026 Medicare Rate (Approx.)
90791	Psychiatric diagnostic evaluation (no medical services)	~$161
90792	Psychiatric diagnostic evaluation (with medical services)	~$213

90791 is the intake code most used by LCSWs, LPCs, LMFTs, and psychologists. 90792 is reserved for prescribers (MDs, DOs, NPs, PAs) who are also evaluating for medication management.

Medicare Telehealth Modifiers: Get These Right or Get Denied

Modifier use is where most billing errors happen in telehealth mental health claims. Here's what you need to know:

Modifier 95 vs. Modifier GT

Modifier 95 — The current standard modifier for synchronous telehealth services (live audio/video). Use this on the claim line for the service code.
Modifier GT — Still accepted by some Medicare Advantage plans, but CMS transitioned to Modifier 95 as the primary identifier. Check payer-specific rules, especially for Medicare Advantage.

Place of Service (POS) Codes

This is critical and frequently misunderstood:

POS 02 — Telehealth provided other than in the patient's home
POS 10 — Telehealth provided in the patient's home

For most outpatient mental health telehealth where the patient is at home (which is the vast majority), you should be using POS 10. Using POS 02 when the patient is at home is a documentation and billing inconsistency that triggers audits.

Pro tip: When you use POS 10, Medicare reimburses at the facility rate rather than the non-facility rate. This can reduce your reimbursement slightly — but using the wrong POS to capture a higher rate is considered fraudulent billing. Accuracy always wins.

Audio-Only Telehealth (Telephone Only)

Medicare still permits audio-only telehealth for mental health services during the extended flexibility period — but with important conditions:

The patient must be unable or unwilling to use video technology.
You must document the patient's inability or refusal in the clinical record.
Use Modifier 93 to indicate audio-only services on applicable claims.

Do not default to audio-only for convenience. Document specifically. CMS has signaled increased scrutiny of audio-only mental health claims.

The In-Person Visit Requirement: What You Actually Need to Know

CMS finalized a rule requiring that Medicare beneficiaries receiving telehealth mental health services have an in-person visit within 6 months prior to initiating telehealth treatment, and at least once every 12 months thereafter.

However, CMS acknowledged this created access barriers and included exceptions:

Waived if the patient's treating provider determines in-person would be a clinically significant barrier (document this explicitly)
Waived through the end of the PHE extension period flexibility in some contexts

What this means for your practice:

Build an in-person visit workflow, even if you're primarily telehealth
Document your clinical reasoning if you're invoking an exception
Track your patients' last in-person visit dates in your EHR

This is an area ripe for audit activity. Your documentation needs to tell the story clearly.

Medicare Advantage Plans: They Play by Different Rules

Here's a reality check: Medicare Advantage (MA) plans are not the same as Traditional Medicare (fee-for-service). Each MA plan can set its own telehealth policies within CMS guidelines — and many do.

Common Medicare Advantage telehealth quirks:

Some plans require prior authorization for telehealth mental health services
Some plans have different preferred codes or modifiers
Reimbursement rates can vary significantly from the physician fee schedule
Some plans still require Modifier GT in addition to or instead of Modifier 95

Before seeing your first Medicare Advantage telehealth patient, call the plan's provider services line, pull the provider manual, or use an eligibility/benefits verification tool. Never assume traditional Medicare rules apply.

Documentation Standards That Protect You in a Telehealth Audit

CMS and its contractors (MACs) have ramped up post-payment audits on telehealth mental health services. Here's what an auditor is looking for in your notes:

Every Session Note Must Include:

Date of service and session start/end times (for time-based codes like 90837, this is non-negotiable)
Confirmation that the session was conducted via telehealth (e.g., "Session conducted via HIPAA-compliant video platform")
Patient's physical location at time of service (especially if audio-only — document state and county)
Provider's physical location (required for interstate licensing compliance)
Patient verbal consent to telehealth services (required per Medicare conditions; document once, then reference it)
Clinical content: presenting concerns, mental status, interventions, response to treatment, plan
Diagnosis codes (ICD-10) that support medical necessity

What Gets Practices Flagged:

Copy-paste notes with identical language across sessions
Missing timestamps on time-based codes
No documentation of technology platform or method of delivery
Vague medical necessity — "patient continued to present with anxiety" without treatment rationale
Mismatched diagnoses between the superbill and clinical note

A well-written session note is your best audit defense. It's also, incidentally, just good clinical documentation.

Common Billing Mistakes to Avoid in 2026

Let's be direct. Here are the mistakes that cost behavioral health practices real money:

Billing 90837 for sessions under 53 minutes. This is one of the top audit triggers. The 53-minute threshold means face-to-face time with the patient, not total session time including notes.
Not verifying Medicare enrollment before billing. LPCs and LMFTs — especially newer Medicare providers — sometimes begin seeing patients before their enrollment is fully processed. Claims will deny.
Ignoring state licensing laws for telehealth. Medicare authorizes billing, but your state board governs whether you can legally provide telehealth across state lines. PSYPACT, LCSW Compact, and Counseling Compact membership matters here.
Using POS 02 when the patient is at home. A frequent and costly mistake.
Failing to document the telehealth consent conversation. CMS requires documented patient consent for telehealth. One signed consent form at intake should be in every chart.
Billing audio-only without proper documentation. Don't just check a box — write the clinical reason.
Not tracking coordination of care time. If you're spending significant time on care coordination between sessions, some of that may be billable under general behavioral health integration codes depending on your setting.

FAQ: Medicare Telehealth Billing for Mental Health in 2026

1. Can I bill Medicare for telehealth therapy if I only see patients via video, and I've never met them in person?

Yes — but you need to meet the in-person visit requirement. Medicare requires an in-person visit within the 6 months prior to initiating telehealth mental health services, and then annually after that. If an in-person visit would be a significant clinical barrier for a specific patient, you can document a clinical exception. Build this workflow into your intake process.

2. I'm an LMFT newly enrolled in Medicare. What do I need to do before billing telehealth?

First, confirm your Medicare enrollment is active and that your billing NPI is enrolled. Then verify you've completed any telehealth-specific credentialing your MAC requires. Obtain signed telehealth consent from patients, confirm you are licensed in the state where the patient is physically located at the time of service, and use Modifier 95 with POS 10 for home-based telehealth services. Don't forget your state's own telehealth regulations — Medicare enrollment doesn't override them.

3. What's the difference between billing 90834 and 90837? Does it really matter?

Yes, significantly. 90834 covers sessions of 38–52 minutes of face-to-face psychotherapy time. 90837 covers 53 minutes or more. The difference in reimbursement is roughly $40 per session nationally — and using 90837 for a 45-minute session is an overcoding error that can trigger audits and recoupment. Always document start and end times, and bill based on actual face-to-face time.

4. My patient sometimes calls me instead of joining the video. Can I still bill Medicare?

You can bill for audio-only (telephone) sessions using Modifier 93, as long as the patient was unable or unwilling to use video technology and you've documented that clinical rationale. Simply preferring a phone call doesn't meet the threshold. Defaulting to audio-only without documentation is a compliance risk — and a pattern of audio-only billing without documentation is a significant audit trigger.

5. How long will these Medicare telehealth flexibilities last?

The current extensions are authorized through December 31, 2026. Congress would need to act again to extend them. CMS has indicated some flexibilities (like LPC/LMFT billing rights) are now permanent. However, the geographic flexibility, POS 10 availability, and audio-only permissions for mental health are tied to the current extension. Watch for the CMS Final Rule each November for updates, and for any legislative action in late 2026.

6. Do I need a special HIPAA-compliant platform to bill Medicare for telehealth?

Medicare requires that telehealth services be delivered via a "communications technology" that allows real-time interactive audio and video. CMS relaxed its HIPAA platform requirements during the COVID PHE, but using a Business Associate Agreement (BAA)-compliant, HIPAA-appropriate platform (e.g., Zoom for Healthcare, SimplePractice, Doxy.me) remains the professional and compliance standard. Document the platform in your note.
