What Medicare Pays vs. What You Might Be Charged
Category Amount
Medicare Allowed Rate What Medicare approves for this service $92.47
Typical Billed Amount What providers commonly charge $120 – $280
Potential Markup How much more you might pay vs. Medicare rate 203% above Medicare
Why the difference? Providers set their own prices. Without insurance, you may be billed the full amount. Even with insurance, your co-pay is often based on the provider's charge — not the Medicare rate.

What CPT Code 90834 Means

When you see CPT code 90834 on your medical bill, it means you received individual psychotherapy that lasted between 38 and 52 minutes. In practice, this typically represents a standard 45-minute therapy session that most patients are familiar with.

Your therapist, psychologist, or psychiatrist uses this code when they provide one-on-one talk therapy to help you work through mental health concerns, relationship issues, anxiety, depression, or other psychological challenges. The session must involve active therapeutic intervention, not just a brief check-in or medication management alone.

This code is used for in-person sessions, telehealth appointments, and phone therapy sessions that meet the time requirements. It's the most commonly billed psychotherapy code because 45-minute sessions are the standard length for most therapeutic practices.

How CPT 90834 Billing Works

The cost for CPT code 90834 varies significantly depending on your location, insurance coverage, and provider. Medicare reimburses providers $92.47 for this service, but private practice rates typically range from $120 to $280 per session.

On your bill or explanation of benefits, you'll see this code listed with the date of service and the charged amount. If you have insurance, you'll also see how much your plan covered and what you owe as a copay, coinsurance, or deductible. Many insurance plans have specific mental health benefits that may cover this code differently than medical services.

Some therapists bill insurance directly, while others require you to pay upfront and seek reimbursement from your insurance company. Make sure to ask about billing practices when you schedule your first appointment to avoid surprises.

Verifying Your CPT 90834 Charges

To check if you were billed correctly for CPT code 90834, first confirm that your session lasted at least 38 minutes and involved active therapy work. If your appointment was shorter or focused only on medication management, a different code should have been used.

Compare the charged amount to typical rates in your area. While prices vary, charges significantly above $280 or below $120 may warrant a question to your provider's billing department. Also verify that the date of service matches when you actually had your appointment.

If you notice an error, contact your therapist's billing office first. Common mistakes include using the wrong time-based code (90832 for shorter sessions or 90837 for longer ones) or billing for sessions that were cancelled. Keep your appointment records and any communication about scheduling changes to help resolve billing disputes quickly.
