CPT Code 90875: The Definitive Biofeedback Therapy Billing Guide for Behavioral Health Providers

Biofeedback therapy sits in an interesting billing gray zone — it's clinically powerful, increasingly evidence-based, and covered by more payers than most practitioners realize. But it's also one of those service areas where documentation missteps and code confusion can tank your reimbursement or trigger an audit.

If you're billing CPT code 90875 — or you're thinking about adding biofeedback to your practice — this guide covers everything you need: what the code actually means, how to document it properly, what payers expect, reimbursement rates, common mistakes, and how to protect yourself when an auditor comes knocking.

Let's get into it.

What Is CPT Code 90875?

CPT code 90875 describes individual biofeedback training by any modality — when provided in conjunction with psychotherapy. The full descriptor from the AMA reads:

"Individual psychophysiological therapy incorporating biofeedback training and psychotherapy (e.g., insight-oriented, behavior modifying, or supportive psychotherapy); 30 minutes"

There's also a companion code:

CPT 90876 — Same as 90875, but for 45-minute sessions
CPT 90901 — Biofeedback training without psychotherapy, any modality

The critical distinction: 90875 and 90876 require psychotherapy to be delivered alongside biofeedback. If you're running a pure biofeedback session without a psychotherapy component, you're in 90901 territory, not 90875.

This distinction matters enormously for billing. Miscoding this is one of the most common errors we see in biofeedback billing, and it's exactly the kind of thing that gets flagged in payer audits.

Who Can Bill CPT 90875?

This is where it gets nuanced. Biofeedback billing eligibility depends on:

Your licensure and scope of practice — In most states, licensed mental health practitioners (LCSWs, LPCs, LMFTs, psychologists) can provide and bill for biofeedback when integrated with psychotherapy. Psychiatrists and other physicians can as well.
Your payer contracts — Not all behavioral health contracts include biofeedback services. Always verify your contract language.
Equipment and training — Many payers require practitioners to demonstrate competency in biofeedback modalities (EEG neurofeedback, EMG, GSR, heart rate variability, etc.) and have appropriate equipment.
State regulations — Some states have specific licensure requirements for biofeedback providers. Check your state licensing board.

Practical tip: If you're an LCSW or LPC billing 90875 for the first time, call your top three payers before submitting claims and ask specifically: (a) Is 90875 a covered benefit under my contract? (b) Are there prior authorization requirements? (c) Is there a session limit per calendar year?

CPT 90875 vs. 90876 vs. 90901: Quick Comparison

| Code | Time | Psychotherapy Required | Typical Use Case | |------|------|----------------------|------------------| | 90875 | 30 minutes | ✅ Yes | Shorter integrated sessions; initial training | | 90876 | 45 minutes | ✅ Yes | Longer integrated sessions; complex cases | | 90901 | Any duration | ❌ No | Standalone biofeedback; physical rehab crossover |

One more nuance: 90875 and 90876 cannot be billed on the same day as standard psychotherapy codes (90832, 90834, 90837) because the psychotherapy is bundled into the biofeedback code. Billing both would be considered unbundling — a compliance violation.

What Conditions Is CPT 90875 Used For?

Biofeedback therapy integrated with psychotherapy has solid evidence across several conditions commonly seen in behavioral health practices:

Anxiety disorders (generalized anxiety, panic disorder, PTSD) — HRV biofeedback is particularly well-studied here
ADHD — EEG/neurofeedback has accumulated a reasonable evidence base
Chronic pain with psychological components — Often billed in integrated care settings
Migraines and tension headaches — One of the longest-standing evidence bases for biofeedback
Hypertension — More common in primary care crossover billing
Insomnia — Increasingly used alongside CBT-I protocols
Stress-related conditions — Including muscle tension, bruxism

Your diagnosis codes need to align with your payer's covered indications. Most commercial payers follow evidence-based guidelines and will deny biofeedback for diagnoses where the evidence is thin. Know your payer's coverage policy before scheduling.

Documentation Requirements: What You Must Have

This is where most providers get into trouble. Biofeedback billing requires more robust documentation than a standard therapy note, because you're documenting both the therapeutic intervention AND the biofeedback training component.

Here's what your documentation needs to include for CPT 90875:

1. Medical Necessity Statement

Explain why biofeedback is clinically indicated for THIS patient with THIS diagnosis at THIS time. Generic language like "patient will benefit from biofeedback" won't survive an audit. Be specific: "Patient presents with panic disorder with physiological hyperarousal and poor interoceptive awareness. HRV biofeedback is indicated to improve autonomic regulation and serve as a real-time feedback mechanism to support CBT respiratory techniques."

2. Biofeedback Modality Documentation

Document which modality you used:

EMG (electromyography)
EEG/neurofeedback (electroencephalography)
GSR (galvanic skin response)
HRV (heart rate variability)
Temperature biofeedback
Respiratory biofeedback

Also document the equipment used. Some payers audit this.

3. Psychotherapy Component

This is non-negotiable for 90875. Your note must clearly document the psychotherapy work that occurred in the session — not just the biofeedback. What therapeutic approach? What insight was worked on? What behavioral skill was practiced? This has to be substantive, not a one-liner.

4. Session Time

Document start and stop times. For 90875, the session must be at least 30 minutes of combined biofeedback training and psychotherapy. Under 30 minutes? You don't have a billable unit.

5. Patient Response and Progress

Document physiological data where available (e.g., HRV coherence scores, EMG baseline vs. session readings) and patient's subjective response. This data is genuinely useful for treatment planning AND it's what separates a strong audit-proof note from a weak one.

6. Treatment Plan Alignment

Biofeedback goals should appear in the treatment plan. If your treatment plan says nothing about biofeedback and you're billing 90875, that's a red flag an auditor will catch immediately.

Reimbursement Rates for CPT 90875

Rates vary significantly by payer, geography, and whether you're in-network. Here are 2024-2025 benchmark estimates:

| Payer Type | Estimated Rate for 90875 | |------------|-------------------------| | Medicare (national avg.) | $54–$68 | | Medicaid (varies by state) | $35–$55 | | Commercial insurance (BCBS, Aetna, UHC) | $75–$130 | | Self-pay / cash rate | $100–$200+ |

Important caveat: Medicare covers biofeedback very selectively. As of current policy, Medicare covers biofeedback (90901 category) primarily for urinary incontinence. Coverage for psychiatric biofeedback (90875/90876) under Medicare Part B is limited and often requires Local Coverage Determination (LCD) review. Check your MAC's LCD before billing Medicare for behavioral health biofeedback.

Medicaid coverage is highly state-specific. Some state Medicaid programs cover 90875 for ADHD and anxiety with specific documentation requirements. Others exclude it entirely. No assumptions here — check your state plan.

Commercial payers are your best bet. BCBS, Aetna, Cigna, and UHC increasingly cover biofeedback for anxiety, PTSD, and ADHD, particularly when prior authorization is obtained and medical necessity is well-documented.

Prior Authorization: What You Need to Know

Many payers require prior authorization for biofeedback services. Here's a general breakdown:

Aetna — Typically requires PA for biofeedback; has a published clinical policy bulletin specifying covered diagnoses and required documentation
UnitedHealthcare — PA often required; references HAYES Health Technology Assessment for coverage decisions
BCBS — Varies by state plan; many require PA and limit sessions (often 20–30 per year)
Cigna — Has a coverage policy for biofeedback; PA requirements vary by plan
Humana — Generally covers with PA for approved indications

Pro tip: When submitting a PA request for 90875, include:

DSM-5 diagnosis with rationale for biofeedback
Proposed modality and equipment
Treatment plan with biofeedback goals
Evidence basis for using biofeedback with this diagnosis (a brief literature reference doesn't hurt)
Number of sessions requested

PA approvals typically run 10–20 sessions at a time. Track your approved sessions carefully — billing beyond authorized sessions without re-authorization is a compliance problem.

Common Billing Mistakes to Avoid

Billing 90875 without documented psychotherapy — The psychotherapy component isn't optional. If it's not in the note, it didn't happen from a payer's perspective.
Unbundling 90875 with 90832/90834/90837 — These cannot be billed together on the same date. The psychotherapy is already included in 90875.
Using 90875 for standalone biofeedback — That's 90901. Using the wrong code is miscoding, period.
Missing session time documentation — Especially relevant when billing 90876 (45-minute code). If your note doesn't document time, you may be downcoded to 90875.
No treatment plan reference — Biofeedback appearing in your billing but not your treatment plan is a consistency problem that auditors flag.
Billing for equipment separately — The equipment/supplies used in biofeedback sessions are not separately billable; they're bundled into the procedure code.
Ignoring payer-specific policies — What Aetna covers isn't what Cigna covers. Generic billing without payer-specific knowledge creates denial patterns.

Audit Defense: Protecting Your Practice

Biofeedback billing is higher on payer radar than standard psychotherapy billing, partly because the codes are less frequently billed and partly because payers know documentation quality in this area is inconsistent.

If you're audited:

Your notes must stand alone — A reviewer who's never met your patient should be able to understand the clinical rationale, what happened in the session, and why it was medically necessary
Physiological data matters — If you have HRV scores, EMG readings, or neurofeedback metrics, keep them in the record. This is objective evidence of the biofeedback component
Consistency across the record — Diagnosis, treatment plan, progress notes, and billing codes must all tell the same story
Contemporaneous documentation — Notes should be completed on the date of service, not reconstructed weeks later

Frequently Asked Questions

1. Can LPCs and LCSWs bill CPT 90875 without physician supervision?

In most states, yes — if biofeedback integrated with psychotherapy falls within your scope of practice and your payer contract covers it. However, scope of practice for biofeedback varies by state. Some states have specific regulations for biofeedback providers. Check your state licensing board's guidance and your payer contract's credentialing requirements before billing.

2. Can I bill 90875 and 90876 on the same day?

No. These codes represent different time durations for the same service. You bill one or the other based on the actual time of the session — not both.

3. Does Medicare cover CPT 90875 for anxiety or PTSD?

Generally, no. Medicare's biofeedback coverage is primarily limited to urinary incontinence under current national policy. Some MACs may have LCD provisions, but behavioral health biofeedback under 90875 is typically not a covered Medicare benefit. Always verify with your specific MAC before billing.

4. How do I document the psychotherapy component in a 90875 note?

The psychotherapy component needs to be substantive. Document the therapeutic modality used (CBT, psychodynamic, supportive, etc.), the specific clinical content addressed (e.g., exploring avoidance patterns, processing somatic anxiety responses), and how the biofeedback data was integrated into the therapeutic work. One sentence won't cut it — aim for a paragraph that clearly demonstrates active psychotherapy occurred alongside the biofeedback training.

5. What's the difference between neurofeedback (EEG biofeedback) and other biofeedback modalities for billing purposes?

From a CPT coding perspective, neurofeedback is billed using the same biofeedback codes (90875, 90876, 90901) — the modality choice (EEG vs. EMG vs. HRV) doesn't change the code. However, some payers have separate coverage policies for neurofeedback specifically and may apply more restrictive criteria. Always check your payer's specific biofeedback AND neurofeedback coverage policies, as they may be separate documents with different covered diagnoses.

6. Can I bill 90875 via telehealth?

Some payers have expanded telehealth coverage for biofeedback, particularly post-2020. However, this requires that the patient has appropriate biofeedback equipment on their end, which creates practical challenges. Document the telehealth platform used, confirm the patient's equipment, and verify your payer's specific telehealth policy for biofeedback codes before billing remotely.

7. How many 90875 sessions can I bill per patient per year?

This is entirely payer-specific. Commercial payers typically authorize 10–30 sessions per year. Some require re-authorization after an initial block. Medicare doesn't cover it for behavioral health, so there's no annual limit to worry about there. Track your authorizations carefully — going over without re-auth is a billing compliance risk.

The Bottom Line on Billing CPT 90875

Biofeedback therapy integrated with psychotherapy is a legitimate, evidence-based service that more payers are covering — but the billing and documentation requirements are more demanding than standard psychotherapy codes. Get the documentation right, know your payer policies, use the correct code for your session type, and you'll build a solid, audit-defensible biofeedback billing practice.

The practitioners who get into trouble with 90875 are almost always the ones who treat it like a standard therapy note. It's not. It requires specificity, physiological data references, documented psychotherapy content, and alignment with a treatment plan that explicitly includes biofeedback goals.
