How to Bill for Mental Health Services: A Step-by-Step Guide for Providers.
Did you know that 73% of mental health providers spend more time on billing and insurance paperwork than they do preparing for their actual therapy sessions?
Did you know that 73% of mental health providers spend more time on billing and insurance paperwork than they do preparing for their actual therapy sessions?
That’s not just a statistic — it’s a heartbreaking reality that’s keeping passionate therapists, counsellors, and psychiatrists from doing what they love most: helping people heal.
If you’re reading this, chances are you’ve felt that frustration too. Maybe you’ve stayed up late wrestling with claim denials, or watched your revenue dwindle because of billing mistakes you didn’t even know you were making.
With the right knowledge and systems, you can transform this necessary evil into a smooth, profitable part of your practice.
Understanding Mental Health Billing Basics
Mental health billing is fundamentally different from general medical billing. While a broken arm is pretty straightforward to code and bill, the human mind? That’s infinitely more complex.
What makes mental health billing unique:
Diagnosis complexity — Mental health conditions often overlap or evolve over time
Treatment duration — Sessions can vary wildly in length and frequency
Privacy concerns — HIPAA requirements are even more stringent
Insurance scrutiny — Many insurers still treat mental health as “less legitimate” than physical health
The good news? Once you understand these fundamentals, everything else becomes manageable.
Essential Billing Components Every Provider Must Know
Think of mental health billing like building a house. You need the right foundation, or everything else crumbles.
The Big Four: Your Billing Foundation
1. Provider Information
Your National Provider Identifier (NPI)
Tax ID number
License numbers for your state
Billing address (which might differ from your practice address)
2. Patient Demographics
Full legal name (exactly as it appears on insurance)
Date of birth
Address
Insurance information (and always verify it’s current!)
3. Service Details
Date of service
Type of service provided
Duration of service
Location (in-person, telehealth, etc.)
4. Diagnosis and Treatment Codes
ICD-10 diagnostic codes
CPT procedure codes
Modifiers when applicable
Documentation:
Here’s something most billing guides won’t tell you: your documentation is your legal defence and your revenue protection rolled into one.
Every session note should tell a story that justifies the service you provided. Insurance companies aren’t trying to deny your claims out of spite — they need to see that the treatment was medically necessary.
CPT Codes for Mental Health Services
CPT codes are like the language of billing — and unfortunately, it’s a language that changes faster than social media trends.
The Most Common Mental Health CPT Codes
Individual Therapy:
90834–45-minute session
90837–60-minute session
90847 — Family therapy with patient present
90846 — Family therapy without patient present
Group Therapy:
90853 — Group psychotherapy
Psychiatric Services:
90791 — Initial psychiatric diagnostic evaluation
90834 — Psychotherapy session
90836 — Psychotherapy with medication management
The Time Trap That Costs Providers Thousands
Here’s where many providers lose money: time-based billing mistakes.
If you provide a 38-minute session, you can’t bill for 90834 (which requires 38–52 minutes). You’d use 90834 for 38–52 minutes, but if you only did 30 minutes, you’d use 90834 for 16–37 minutes.
The golden rule: Always document your actual start and end times. When in doubt, round down, not up.
ICD-10 Diagnosis Codes in Mental Health
ICD-10 codes are like GPS coordinates for mental health conditions — they tell insurance companies exactly where your patient is on their mental health journey.
Major Categories You’ll Use Daily
Anxiety Disorders (F40-F48)
F41.1 — Generalized anxiety disorder
F41.0 — Panic disorder without agoraphobia
F40.10 — Social phobia, unspecified
Mood Disorders (F30-F39)
F32.9 — Major depressive disorder, single episode, unspecified
F33.1 — Major depressive disorder, recurrent, moderate
F31.9 — Bipolar disorder, unspecified
Trauma and Stress-Related Disorders (F43)
F43.10 — Post-traumatic stress disorder, unspecified
F43.21 — Adjustment disorder with depressed mood
The Diagnosis Documentation Dance
Here’s what insurance companies want to see:
Clear symptom documentation — Not just “patient reports anxiety” but specific symptoms
Functional impairment — How the condition affects work, relationships, daily activities
Treatment progress — Is the patient improving, stable, or declining?
Medical necessity — Why this level of care is appropriate
Insurance Claims and Reimbursement Process
Insurance billing for mental health services is like navigating a maze blindfolded — but once you learn the patterns, you can walk through it with confidence.
The Claim Lifecycle: From Session to Payment
Step 1: Pre-Authorization Some insurance companies require pre-authorization for mental health services. This isn’t personal — it’s business. Get this handled before you start treatment.
Step 2: Service Delivery Provide your service and document everything. Remember: if it’s not documented, it didn’t happen (at least according to insurance companies).
Step 3: Claim Submission Submit your claim within the insurance company’s timeframe. Most require submission within 90–365 days, but don’t wait. Submit early, get paid faster.
Step 4: Claim Processing The insurance company reviews your claim. This is where proper coding and documentation pay off.
Step 5: Payment or Denial If approved, you get paid. Should your request be denied, you’ll receive an explanation and may initiate an appeal.
Common Reimbursement Roadblocks
The “Not Medically Necessary” Trap This is insurance-speak for “we don’t understand why this patient needed this service.” Combat this with detailed documentation that clearly links symptoms to treatment interventions.
The Duplicate Claim Surprise Sometimes insurance systems flag legitimate claims as duplicates. Keep detailed records of what you’ve submitted and when.
Common Billing Mistakes and How to Avoid Them
After working with hundreds of mental health providers, I’ve seen the same mistakes repeated over and over. The good news? They’re all preventable.
The Top 5 Costly Mistakes
1. The Modifier Mishap Modifiers are like seasoning — a little goes a long way, but too much ruins everything. Use them correctly or face claim denials.
2. The Time Documentation Disaster Billing for a 45-minute session when you only provided 30 minutes isn’t just wrong — it’s fraud. Always document actual time spent.
3. The Insurance Verification Vacation Failing to verify insurance before each session is like driving without checking if you have gas. You might make it, but probably not.
4. The Diagnosis Drift Changing diagnoses without proper documentation looks suspicious to insurance companies. Document your clinical reasoning for any changes.
5. The Claim Submission Slumber Waiting months to submit claims is like leaving money on the table. Most insurance companies have strict deadlines.
The Prevention Prescription
Create systems, not just intentions.
Weekly insurance verification for all active patients
Daily claim submission routine
Monthly accounts receivable review
Quarterly coding audit of your most common codes
Setting Up Efficient Billing Systems
Efficient billing isn’t about working harder — it’s about working smarter.

Frequently Asked Questions
How much do mental health providers typically get reimbursed per session?
Mental health reimbursement rates vary significantly by location, insurance type, and provider credentials. Private insurance typically pays $80–150 per individual therapy session, while Medicare and Medicaid rates are generally lower, ranging from $45–90 per session. In-network providers usually accept negotiated rates that are 10–30% lower than their standard fees, but benefit from guaranteed payment and steady patient referrals. Out-of-network providers can charge full rates but patients face higher out-of-pocket costs.
2. What’s the difference between billing insurance directly vs. patient pay?
Direct insurance billing means you submit claims to insurance companies and collect payment from them (minus patient copays/deductibles). You handle all the paperwork but get guaranteed payments for covered services.
Patient pay (or superbill) billing means patients pay you directly, then submit your detailed receipt (superbill) to their insurance for reimbursement. This reduces your administrative burden but may result in slower payments and collection challenges.
Many successful practices use a hybrid approach — billing major insurances directly while using superbills for smaller or problematic insurance companies.
3. How long does it typically take to get paid by insurance companies?
Most insurance companies pay clean claims within 14–30 days of submission. However, this timeline can stretch to 45–90 days for complicated claims or during high-volume periods.
Electronic claims process faster than paper claims. Medicare typically pays within 14 days, while some commercial insurers may take up to 45 days.
Red flag: If you haven’t received payment or explanation of benefits within 45 days, follow up immediately. Many practices lose thousands of dollars by not tracking unpaid claims.
4. Can I bill for telehealth mental health sessions the same way as in-person visits?
Yes, telehealth mental health sessions use the same CPT codes as in-person sessions (90834, 90837, etc.). However, you must add modifier 95 or GT depending on the insurance company’s requirements.
Key telehealth billing requirements:
Patient must be in a private, HIPAA-compliant setting
You must use a secure, encrypted platform
Document the telehealth platform used in your notes
Verify the patient’s location for state licensing compliance
Most insurance companies now cover telehealth at the same rate as in-person visits, but always verify coverage before providing services.
6. How do I handle patients who can’t afford their copays or deductibles?
This is one of the most challenging aspects of mental health billing. You have several ethical options:
Sliding fee scales: Adjust your rates based on patient income (ensure this complies with insurance contracts)
Payment plans: Break larger balances into manageable monthly payments
Hardship policies: Some practices write off balances for patients experiencing genuine financial hardship
Community resources: Help patients find free or low-cost mental health services when appropriate
Important: Never waive copays routinely — this violates most insurance contracts and can be considered fraud.
