Mastering 90875 CPT Code: Step-by-Step Billing Guidelines

Stanley Efrem

Oct 6, 2025

Mental health providers lose thousands of dollars each year due to incorrect 90875 CPT code usage and documentation errors. Proper implementation of this specialized code protects your practice's financial stability while securing fair reimbursement for the valuable biofeedback services you deliver to clients.

CPT Code 90875 covers individual psychophysiological therapy that incorporates biofeedback training within 30-minute sessions. This code applies to therapy that integrates biofeedback techniques into mental health treatment processes. Sessions must also include psychotherapy approaches like cognitive-behavioral therapy (CBT) or insight-oriented therapy, customized to each client's unique requirements.

Average reimbursement rates for CPT Code 90875 differ across insurance types. Medicaid pays approximately $60 per session, Medicare averages $65, and private insurance typically reimburses around $75. Accurate application of this code becomes essential for your practice's revenue and long-term sustainability.

This guide provides the specific requirements for using CPT code 90875 correctly. You'll learn documentation standards that meet medical necessity criteria and billing strategies that optimize reimbursement. These guidelines help you avoid costly mistakes while ensuring appropriate compensation for the specialized biofeedback therapy you provide.

Understanding CPT Code 90875: Core Requirements and Applications

The 90875 CPT code describes a specialized therapy that merges physiological monitoring with psychological treatment. Accurate billing requires understanding the exact requirements for this code.

Psychophysiological Therapy Coverage Under CPT Code 90875

CPT Code 90875 applies to individual psychophysiological therapy sessions that blend biofeedback training with psychotherapy. Clients learn to recognize and control physiological functions including heart rate, muscle tension, temperature variations, and breathing patterns.

The code requires both components working together. Standard psychotherapy codes don't include biofeedback monitoring, while 90875 specifically demands biofeedback techniques paired with therapeutic interventions like insight-oriented therapy, cognitive-behavioral approaches, or supportive counseling.

This code appears under "Other Psychiatric Services or Procedures" within the Current Procedural Terminology system [6]. The treatment bridges traditional psychological methods with modern monitoring technology, helping clients identify and adjust their physical responses to emotional triggers.

Session Duration: The 30-Minute Standard

Session timing for CPT 90875 follows specific guidelines. While earlier versions covered 20-30 minute sessions, current standards require exactly 30 minutes. These 30 minutes typically break down into 20-25 minutes of direct client contact, plus 5-10 minutes for documentation and equipment preparation.

Direct interaction remains mandatory. Sessions conducted in-person or through telehealth must maintain therapist-client contact throughout the treatment. This requirement separates 90875 from standalone biofeedback codes (90901, 90911) that operate without psychotherapy components or face-to-face interaction [7].

Provider Eligibility: Who Can Bill CPT Code 90875

Qualified providers for CPT code 90875 include:

Clinical Psychologists
Licensed Clinical Social Workers (LICSW)
Licensed Marriage and Family Therapists (LMFT)
Licensed Professional Clinical Counselors (LPCC)
Psychiatrists
Psychiatric Nurse Practitioners [4]

Clinical Documentation and Medical Necessity Standards

Proper documentation determines reimbursement success for CPT code 90875 services. Medicare and private payers demand specific elements that validate service delivery and medical necessity.

Documenting Biofeedback Techniques and Psychotherapy Integration

Complete notes must capture both components of the 90875 service. Your documentation should specifically record:

Biofeedback methods employed (equipment used and physiological processes targeted)
Psychotherapy techniques applied (cognitive restructuring, supportive interactions)
Exact face-to-face session duration (30 minutes)
Client's response and progress toward treatment goals

Instead of simply noting "biofeedback performed," document "breathing exercises with heart rate variability monitoring combined with cognitive restructuring to address anxiety symptoms". This approach shows the integration of both therapeutic elements required for this code.

Establishing Medical Necessity with Functional Impairment Evidence

Medical necessity documentation must show that services are reasonable and necessary for diagnosis or treatment. Your records should establish:

Presence of a psychiatric illness or emotional/behavioral symptoms altering baseline functioning [7]
Individualized treatment plan with specific goals
Reasonable expectation of improvement or stabilization
Periodic updates (typically every three months)

Therapy must reduce symptoms to prevent relapse or hospitalization while improving or maintaining functioning [8]. Once stability can be maintained without further treatment, services are no longer medically necessary [8].

Examples of Weak vs. Strong Documentation for Anxiety Treatment

Weak: "Client received biofeedback for anxiety. Will continue next week."

Strong: "Client demonstrated elevated autonomic arousal (HR 95 BPM) when discussing work stressors. Applied diaphragmatic breathing with HRV monitoring, reaching 75 BPM. Integrated cognitive restructuring of catastrophic thinking. Client reported decreased subjective distress (7/10 to 4/10) and demonstrated improved vagal tone".

Using Objective Data: Heart Rate, EMG, and Skin Conductance

Objective physiological measurements provide strong evidence for both treatment necessity and effectiveness. Studies indicate biofeedback can reduce headache pain [9] and may improve conditions like fecal incontinence [10]. Evidence quality varies across conditions.

Record specific measurements showing physiological changes during treatment. Include quantifiable data points that demonstrate therapeutic progress and justify continued treatment rather than relying on subjective statements alone.

Billing Strategy and Reimbursement Optimization

Strategic billing approaches for CPT code 90875 protect your practice revenue while ensuring appropriate compensation for specialized biofeedback services. Success requires understanding authorization requirements, geographic payment variations, and correct modifier application.

Pre-Authorization Requirements by Insurance Type

Most insurance carriers require pre-authorization for biofeedback services. Contact the insurance provider before starting treatment to verify:

Number of authorized visits
Coverage limitations
Patient copay responsibilities
Specific documentation requirements

Medicare Advantage plans typically mandate prior authorization for mental health services [11]. State Medicaid programs often impose session limitations before requiring authorization [12]. Some Medicaid systems automatically deny claims exceeding session limits without proper authorization [12].

Geographic and Plan-Based Reimbursement Variability

Reimbursement rates for CPT code 90875 fluctuate based on multiple factors.

Insurance plan types directly affect payment rates. Private insurance typically offers higher reimbursement than government programs. Medicare allows licensed professional counselors and marriage/family therapists as in-network providers, though at only 75% of the standard mental health service rate [13].

Geographic location substantially impacts reimbursement. Urban areas often command higher rates than rural regions [5]. Individual state requirements plus regional cost factors influence final payment amounts.

Using Modifiers: 25, 59, 95, and GT for Telehealth

Modifier usage directly affects claim acceptance. Key modifiers for CPT code 90875 include:

25: Applied when a separately identifiable evaluation service occurs the same day 59: Indicates a distinct procedural service 95: Used for synchronous telemedicine via real-time audio/video GT: Designates telehealth services provided through audio and video

Modifier usage varies by payer and state. Medicaid in Texas often requires modifier 25 to separate medication checks from therapy provided by the same clinician [14].

Session Frequency Guidelines: Initial vs. Maintenance Phase

Initial treatment typically involves 2-3 sessions weekly for 4-6 weeks, establishing baseline measurements and developing self-regulation skills. Maintenance sessions usually transition to once weekly following this intensive phase. Duration depends on progress and treatment goals.

Audit-Proofing and Compliance Best Practices

Compliance with CPT code 90875 demands careful attention to documentation standards and regulatory requirements. Proper preparation protects your practice from costly audits and claim denials.

Avoiding Common Mistakes in CPT Code 90875 Claims

Claim denials frequently result from preventable documentation and coding errors. The most common mistakes include inaccurate session time logging—failing to record the exact 30-minute duration this code requires. Incomplete documentation of both biofeedback techniques and psychotherapy components also leads to rejections. Never unbundle services by billing separately for components already included in the 90875 code, such as therapeutic exercises during biofeedback training [3].

Therapeutic Alliance and Progress Tracking in Notes

Progress notes must document the therapeutic relationship alongside technical elements. Strong documentation includes:

Symptom descriptions and client subjective reports
Observable physiological data (heart rate, muscle tension measurements)
Specific interventions with clinical rationale
Progress toward individualized treatment objectives

The most compelling evidence tracks measurable physiological changes alongside behavioral improvements. Your notes must justify continued treatment by showing either symptomatic improvement or prevention of deterioration [15].

HIPAA-Compliant Documentation for Biofeedback Sessions

HIPAA regulations provide special protection for psychotherapy notes, but this doesn't eliminate documentation requirements. Maintain compliance while protecting privacy by creating separate files: one containing protected psychotherapy content, another with clinical information needed for billing. You remain responsible for extracting information required for medical necessity reviews.

Electronic documentation requires proper signature authentication. Use multi-factor authentication for identifying users who sign notes, combined with automatic timestamping [17].

Secure Your Practice Revenue with Proper CPT 90875 Implementation

CPT code 90875 billing success depends on precise documentation and strategic implementation. Your practice deserves fair compensation for the specialized biofeedback services you provide to clients. Proper coding protects your financial stability while ensuring patients receive the quality care they need.

Quality documentation determines reimbursement outcomes. Document exactly how heart rate variability training addresses your client's specific autonomic dysregulation patterns. Show the connection between biofeedback interventions and measurable therapeutic progress. This approach justifies continued treatment while demonstrating real clinical value.

Pre-authorization requirements vary significantly across insurance providers. Medicare restricts this code to physicians only, while other payers have different coverage criteria. Verify guidelines before starting treatment to avoid claim delays and denied payments.
