Behavioral & Mental Health Billing

Route the encounter first. Bill it second.

Under the 2026 telehealth flexibility extension, audio-only behavioral health is still payable by Medicare, but the money now lives in three fields: place of service, the audio modifier, and the practitioner attestation. Get the route right and the claim clears clean.

The short answer: If the member is at home, bill POS 10. If they are anywhere else, bill POS 02. Append 95 for audio-video or 93 for audio-only, and add Medicare's FQ when the behavioral health visit was furnished audio-only. The mental health in-person visit requirement stays paused for the duration of the current extension.

What changed for 2026

The flexibility survived. The precision did not get easier.

The CY2026 Medicare Physician Fee Schedule Final Rule keeps behavioral and mental health telehealth expansive: the patient's home is a valid originating site, geographic restrictions do not apply, and audio-only is permitted when the member cannot use or does not consent to two-way video. What trips up claims is not eligibility. It is the routing.

Place-of-service codes carry every telehealth claim: 02 and 10

The routing engine

One encounter, four decisions

Walk any behavioral health telehealth visit down this path before it touches the clearinghouse. Each node answers one question and hands you one field.

Is this a distant-site telehealth service?

Confirm the rendering practitioner is enrolled and the service is on Medicare's telehealth-eligible list (psychotherapy, evaluation and management, and the 90000-series behavioral health codes remain covered under the CY2026 PFS). If yes, continue. If no, this is not a telehealth claim.

Where was the patient sitting?

Location sets the place of service, and place of service sets the payment rate.

Patient at home POS 10 Telehealth in the patient's home. Pays at the non-facility rate.

Patient elsewhere POS 02 Telehealth other than in the home. Pays at the facility rate.

Was it video, or voice only?

The modality modifier tells the payer how the visit was delivered. This is the field most likely to be missing on an audio-only claim.

Two-way audio-video Modifier 95 Synchronous real-time telehealth.

Audio only Modifier 93 + FQ CPT 93 for audio-only, plus Medicare's FQ on behavioral health services.

Does the record back the audio-only choice?

For audio-only behavioral health, the note should reflect that the practitioner was technically capable of video and the member either could not use it or declined it. Under the current extension, no separate in-person visit within the prior six months is required to unlock the audio-only benefit. Document the reason, then release the claim.

Place of service, decoded

POS 10 and POS 02 are not interchangeable

Choosing the wrong one does not deny the claim. It quietly pays it at the wrong rate, and that gap only surfaces months later in a reconciliation nobody scheduled.

Telehealth in the patient's home

Member is physically located at their residence during the session.
The default for most home-based behavioral health telehealth.
Reimbursed at the non-facility rate.

RATE PROFILE: non-facility · typically the higher of the two

Telehealth other than in the home

Member is at a clinic, group home, SUD facility, or other non-home site.
Use when the originating site is anything but the residence.
Reimbursed at the facility rate.

RATE PROFILE: facility · typically the lower of the two

Modifier decoder

Four modifiers do the talking

Synchronous audio-video

Real-time interactive telehealth with both audio and video. The standard modifier for a video behavioral health session.

Synchronous audio-only

CPT modifier for a live telephone or voice-only encounter when video was not used.

Audio-only behavioral health

Medicare HCPCS modifier flagging that a behavioral or mental health service was furnished audio-only. Pair with 93 on Medicare claims.

Supervising practitioner via video

Signals a supervising practitioner was present through real-time audio-video when the service requires supervision. Situational, not routine.

The extension, in sequence

Why the in-person requirement is still paused

Statute

Mental health telehealth made permanent, with a catch

Congress permanently removed the geographic and originating-site limits for mental and behavioral health telehealth, but attached an in-person visit requirement (a face-to-face within six months of the first telehealth service, then periodically).

Extensions

Enforcement repeatedly delayed

Successive Congressional telehealth extension acts have pushed back the start date of that in-person requirement each time the broader Medicare telehealth flexibilities were extended.

CY2026 PFS

The Final Rule reflects the current extension

For dates of service under the active extension, the in-person visit requirement is not enforced, and audio-only behavioral health remains payable when the member cannot use or declines two-way video. Confirm the extension's end date against the current CMS guidance before each billing cycle, because these windows move.

Where clean claims go sideways

The five audio-only mistakes we correct most

The mistake	What happens	The fix
POS 02 for a home visit	Claim pays at the lower facility rate; revenue leaks silently.	Use POS 10 whenever the member is at home.
No audio-only modifier	Payer assumes video; audit exposure when the record shows voice only.	Append 93 and, on Medicare, FQ.
Missing modality note	Audio-only visit lacks the reason video was not used.	Document decline or inability at the point of care.
Holding claims for an in-person visit	AR ages waiting on a requirement that is not being enforced.	Bill under the current extension; track the sunset date.
Legacy GT modifier	Outdated modifier surfaces on rebills and triggers rejections.	Replace with 95 or 93 as the modality dictates.

Verify the active extension window against current CMS guidance before each billing cycle, since these dates are set by Congress and revised periodically.

Stop losing rate on the routing

A regional behavioral health group we work with was billing audio-only sessions correctly on eligibility but leaking on place of service and missing the FQ flag on a third of Medicare claims. Fixing the routing, not the coverage, is where the recovery lives. ASP-RCM builds these decision rules into your scrubber so the right POS, modifier, and attestation are on the claim before it goes out.
