CPT Code 90845: Psychoanalysis Billing Guidelines

CPT Code 90845 is a specialized code used to document and bill for psychoanalysis services. This code is specifically designed for therapists and healthcare providers trained in psychoanalytic techniques, offering a unique approach to understanding and treating mental health conditions.

Key Features of CPT Code 90845

Here are some essential things to keep in mind when billing for CPT code 90845:

• Not Time-Based: Unlike other psychotherapy codes (90832, 90834, 90837), CPT code 90845 is not time-based. This means you don’t need to track the exact duration of each session. This distinction is crucial for billing purposes, as it allows for a focus on the session itself rather than its duration.  
• Billed Per Session: You can bill CPT code 90845 once per day for each psychoanalysis session, regardless of how long the session lasts.  
• Typical Session Duration: While not time-based for billing purposes, psychoanalysis sessions generally range from 45 to 50 minutes.  
• Documentation Requirements: Accurate and detailed documentation is crucial for all medical billing, and CPT code 90845 is no exception. Be sure to document the date of service, the patient’s diagnosis, and a brief summary of the session’s content.

Who Can Bill for CPT Code 90845?

Not just any mental health professional can bill for psychoanalysis. This service requires specialized training and credentials. Typically, the following licensed professionals are qualified to provide and bill for psychoanalysis:

• PhD or PsyD in Psychology: Psychologists with doctoral degrees in clinical psychology or a related field.
• MD in Psychiatry: Psychiatrists who have completed specialized training in psychoanalysis.
• Some Licensed Clinical Social Workers (LCSWs): In some cases, LCSWs with advanced training and certification in psychoanalysis may be eligible to bill for this service.

It’s crucial to verify with individual insurance payers to confirm their specific requirements for credentialing and billing psychoanalysis services.

When to Use CPT 90845

CPT Code 90845 is appropriate in scenarios where psychoanalysis is medically necessary to treat complex mental health conditions. Common use cases include:

1. Chronic Mental Health Disorders: For patients with long-standing conditions such as depression, anxiety disorders, or personality disorders requiring deep psychological exploration.
2. Trauma Recovery: Addressing unresolved trauma through psychoanalytic techniques.
3. Unconscious Thought Patterns: Exploring unconscious conflicts that may contribute to maladaptive behaviors or emotional distress.
4. Treatment Resistance: For patients who have not responded to traditional psychotherapy methods and require a more intensive approach.

Common Mistakes to Avoid When Billing CPT Code 90845

1. Incomplete Documentation: Failing to include detailed clinical notes can result in claim denials during audits.
   
2. Incorrect Use of Modifiers: Omitting necessary modifiers or using them incorrectly can lead to underpayment or rejection of claims.
   
3. Billing Without Verification: Not confirming insurance coverage beforehand may result in denied claims or unexpected patient bills.
   
4. Overusing This Code: Repeatedly billing psychoanalysis sessions without sufficient justification may raise red flags during audits.

Billing Guidelines for CPT Code 90845

Accurate billing for CPT Code 90845 requires adherence to specific guidelines to ensure compliance and proper reimbursement:

1. Documentation Requirements

Maintain detailed clinical notes summarizing the patient’s diagnosis, symptoms, and progress toward treatment goals. Document the psychoanalytic techniques used during the session and include ICD-10 diagnosis codes that justify the need for psychoanalysis (e.g., F32.9 for Major Depressive Disorder). Proper documentation supports medical necessity and minimizes claim denials.

2. Session-Based Billing

Unlike other psychotherapy codes that specify time limits (e.g., 30 or 60 minutes), CPT Code 90845 is billed per session rather than by time duration. Each session must be documented separately, detailing the interventions provided and the patient’s response to treatment.

3. Verify Insurance Coverage

Before providing services, check with the patient’s insurance provider to confirm whether CPT Code 90845 is covered under their policy. Some private insurers may impose restrictions, require prior authorization, or have specific conditions for reimbursement. Verifying coverage in advance helps prevent unexpected claim denials.

4. Use Appropriate Modifiers

Modifiers clarify specific circumstances of the service provided and help avoid claim rejections:

• Modifier -25: Used when a significant, separately identifiable service is performed on the same day as another procedure.
• Modifier -59: Applied when distinct procedural services are billed on the same day as other therapy codes.

Reimbursement Rates for CPT Code 90845

Reimbursement rates for CPT Code 90845 vary based on factors such as geographic location, payer policies, and provider type. For Medicare patients, the average reimbursement rate is approximately $96 per session (2025 rates). Private insurers may offer higher or lower rates depending on their fee schedules.

To determine exact reimbursement amounts:

• Consult the Medicare Physician Fee Schedule (MPFS) available on the CMS website.
• Verify rates with individual private payers.

Best Practices for Maximizing Reimbursement

To ensure accurate billing and maximize reimbursement for CPT Code 90845:

1. Train Staff Thoroughly: Provide ongoing training on coding updates, payer-specific requirements, and proper documentation practices.
2. Leverage Technology: Use billing software with built-in checks for coding accuracy and documentation completeness.
3. Monitor Denial Trends: Regularly review denial reports to identify patterns and address root causes promptly.
4. Communicate with Patients: Clearly explain what services are covered by their insurance plan versus what may require out-of-pocket payment.
5. Verify Payer Policies: Stay informed about changes in coverage policies or reimbursement rates for psychoanalysis services.
