What We’re Seeing Across 50 Behavioral Health Practices in 2026

At Revenant Care Group, we work directly with approximately 50 behavioral health practices ranging from solo outpatient clinics to multi-site SUD programs billing $2M to $15M annually. The pattern we’re seeing in 2026 is unmistakable: audio-only telehealth visits remain one of the most consistently mishandled claim categories in behavioral health billing. Practices are either over-restricting audio-only to avoid denials, leaving legitimate revenue uncollected, or billing it incorrectly and triggering post-payment audits that claw back months of reimbursement.

The stakes are real. A mid-size behavioral health group seeing 300 audio-only visits per month and billing them incorrectly or not at all is leaving between $18,000 and $45,000 on the table monthly, depending on payer mix and geography. This post breaks down exactly how audio-only telehealth coverage works in 2026, which payers are paying, which are pulling back, and what your billing team needs to do differently starting now.

The Coding Framework for Audio-Only Behavioral Health in 2026

Audio-only behavioral health visits are billed using the same CPT code set as standard telehealth, but the modifier and place of service (POS) combination is what determines whether a claim pays or denies. Here is the framework your team should be using:

• CPT codes: 90832, 90834, 90837 for individual psychotherapy; 90847 for family therapy; 90853 for group therapy; 99213, 99214 for E/M visits with a behavioral health component when rendered by an MD or NP
• Modifier 93: This is the designated modifier for audio-only synchronous telehealth services. It replaced the informal use of Modifier GT for this purpose. Missing this modifier on an audio-only claim is the single most common reason for denial on commercial plans in 2026.
• POS 02 vs. POS 10: POS 02 indicates telehealth provided other than in a patient’s home. POS 10 indicates telehealth provided in a patient’s home. For audio-only, the correct POS depends on where the patient is located during the call, not where your provider is located. We see this miscoded in roughly 30% of new client accounts we audit.
• Modifier FQ: Required by Medicare when audio-only is used because video was not available to the patient. This modifier must be appended in addition to Modifier 93 for Medicare claims.

Stacking Modifier 93 with the correct POS code and, for Medicare, Modifier FQ, is the billing foundation. Everything else flows from getting this right on every single claim.

Medicare Coverage for Audio-Only BH Telehealth in 2026

Medicare extended its behavioral health telehealth flexibilities through December 31, 2026, under the provisions carried forward from pandemic-era waivers and codified in subsequent legislation. Audio-only coverage for behavioral health services is permitted under Medicare Part B when two conditions are met: the patient has a clinical or technological barrier to video, and the provider documents that barrier in the medical record.

The documentation requirement is where we see practices fail audits. “Patient unable to use video” is not sufficient documentation. Your EHR notes need to specify the barrier, such as the patient lacking a smartphone, lacking reliable internet access, or having a cognitive or sensory limitation that makes video non-functional. Without this specificity, recoupment risk is high. Medicare’s fee schedule for CPT 90837 via audio-only with Modifier 93 and FQ is approximately $134 to $142 nationally for 2026, depending on locality. That is roughly 85% of the video telehealth rate, which is itself slightly below in-person rates in most localities.

For practices serving high-Medicaid, high-Medicare populations in rural or underserved areas, audio-only can represent 20% to 35% of total telehealth volume. Getting the coding right on that segment is not a minor cleanup item; it is a revenue integrity priority.

Commercial Payer Policies: Who Pays, Who Restricts, and Who Has Changed in 2026

Commercial payer coverage for audio-only behavioral health is fragmented, and it has shifted in 2026. Here is what we are seeing across the major payers in our client base:

• Aetna: Covers audio-only behavioral health telehealth as of 2026 with Modifier 93 required. POS 10 accepted when patient is at home. Aetna has tightened its medical necessity language and now requires that audio-only be clinically justified in the record, not just administratively convenient.
• UnitedHealthcare: Covers audio-only BH telehealth under most commercial plans. UHC has added a voice modifier requirement aligned with CMS guidance. We are seeing UHC denials increase on claims missing Modifier 93, up from a minor issue in 2024 to a significant denial driver in early 2026.
• BCBS plans (varies by state): Coverage is inconsistent. Several Blue Cross affiliates have reinstated pre-authorization requirements for audio-only visits exceeding 8 per calendar year per patient. If your practice is in a BCBS-heavy market, this is a utilization management tripwire you need to track proactively.
• Medicaid (state-by-state): Most state Medicaid programs that adopted audio-only during the PHE have retained it, but rate parity with video telehealth is not universal. In states without explicit audio-only parity, you may be billing at a lower fee schedule without realizing it.

Mental health parity law is a lever practices underuse here. If a commercial plan covers video telehealth for a medical condition without prior auth, denying or restricting audio-only behavioral health telehealth without equivalent justification is a potential parity violation. We have written directly about how to use parity appeals to recover this revenue: MHPAEA parity appeals and how behavioral health practices are leaving money on the table. If audio-only denials are clustering on a specific commercial payer, a parity-based appeal pathway may be your best recovery tool.

The Revenue Impact by Practice Size

We calculate audio-only telehealth revenue impact in tiers based on practice volume, because the correction effort is fixed but the recovery scales with visit count:

• Small practice (under 500 visits/month total, 15-20% audio-only): Incorrect audio-only billing typically costs $4,000 to $9,000 per month in net revenue. Correcting modifier and POS errors alone recovers most of this within 60 days.
• Mid-size practice (500-1,500 visits/month, 20-30% audio-only): Revenue loss from miscoded or unbilled audio-only visits runs $12,000 to $35,000 per month. This is where payer-specific policy non-compliance (missing Modifier 93 on UHC, missing FQ on Medicare) creates the largest denial volume.
• Large or multi-site group (1,500+ visits/month): Audio-only coding errors at this scale can exceed $50,000 per month in delayed or denied revenue. At this size, systematic claim-level audits by payer and CPT code are necessary, not optional.

The recoverable percentage in our experience across audits is typically 70% to 85% of denied audio-only claims when the denial is purely a coding or modifier error and the clinical documentation supports medical necessity. Claims denied for missing documentation or untimely filing have lower recovery rates, which is why prospective correction outperforms retroactive appeals at every practice size.

What Your Billing Team Should Audit This Week

If you manage RCM for a behavioral health practice and you have not done a targeted audio-only audit in the last 90 days, here is the minimum viable review to run immediately:

• Pull all 90832, 90834, 90837, and 90847 claims from the past 90 days billed with POS 02 or POS 10.
• Confirm Modifier 93 is present on every audio-only claim. Any claim missing it that was submitted to a commercial payer after January 1, 2025, is likely denied or at risk.
• For Medicare claims in the same date range, confirm Modifier FQ is appended alongside Modifier 93.
• Cross-reference your denial report for CO-4 (incorrect procedure/modifier combination) and CO-97 (service included in another service) denial codes, which are common on audio-only claims with modifier errors.
• Review any BCBS claims for patients with more than 8 audio-only visits in 2026 to confirm prior auth was obtained where required.

For SUD-focused practices, audio-only visit coding intersects with your broader telehealth and diagnostic billing integrity. If your drug screen coding is also under review, our analysis of G0480-G0483 drug screen coding and why most SUD practices are under-coding covers a parallel revenue recovery opportunity worth reviewing alongside your telehealth audit.
