Behavioral health billing is not standard medical billing. The payer environment is different. The code sets are different. The compliance requirements, specifically 42 CFR Part 2 for substance use disorder treatment, are more restrictive than HIPAA. And the authorization logic for IOP, PHP, and residential levels of care follows ASAM criteria that most general billers have never encountered.
Finding a billing company that actually understands behavioral health requires knowing what to look for. This guide covers the key considerations and the options worth evaluating in 2026.
What Makes Behavioral Health Billing Different
Before evaluating companies, it helps to understand what separates behavioral health billing from general medical billing.
42 CFR Part 2 Compliance
Substance use disorder treatment records are protected by federal confidentiality regulations that go beyond standard HIPAA. 42 CFR Part 2 restricts what information can appear on a claim or in billing communications without specific patient consent. Billers who don’t understand this create compliance exposure on every SUD claim they submit.
Behavioral Health Carve-Outs
Most commercial payers carve behavioral health benefits out to a managed behavioral health organization: Magellan, Optum Behavioral, Beacon Health Options, Value Options. Claims submitted to the primary commercial insurer deny CO-109. They must go to the carve-out. A biller who doesn’t know the carve-out routing for your payer mix will generate systematic denials.
ASAM Level of Care Authorization
Payers use the American Society of Addiction Medicine criteria to authorize specific levels of care. An authorization for outpatient doesn’t extend to IOP. An IOP authorization doesn’t extend to PHP. Each transition requires a new authorization. Billers who miss this generate denials for every session billed at the wrong level.
H-Code and Revenue Code Billing
IOP programs bill using H0015 combined with CPT therapy codes and revenue code 0905. PHP programs bill H2019 per diem. SUD counseling bills H0004 per 15 minutes. These are not codes a general biller knows. A practice that switches from outpatient to IOP and doesn’t update their billing workflow will have their IOP claims denying indefinitely.
What to Look for in a Behavioral Health Billing Company
Specific things to ask any billing company before engaging:
- Do your billers know 42 CFR Part 2 and how it affects claim submissions?
- Can they name the managed behavioral health organizations for your top payers?
- Have they billed H0015 and H2019 before?
- Do they understand ASAM level of care authorization workflow?
- Have they worked with Kipu, Procentive, TheraNest, or whatever platform you run?
If the answer to any of these is vague, the biller doesn’t have behavioral health billing experience. They have general billing experience and are hoping to learn on your account.

Dedicated billing staffing model. One biller assigned exclusively to your practice, working in your EHR during your office hours. Behavioral health billers are trained in 42 CFR Part 2, carve-out routing, ASAM authorization, H-code and revenue code billing, and CARF documentation requirements.

BillingParadise
Full-service billing company with behavioral health experience. Percentage-based pricing, typically 4 to 8 percent of collections. Handles mental health and SUD billing. Less transparency on biller specialization or dedicated assignments.
Coronis Health
Larger RCM company serving multi-site behavioral health organizations and hospitals. Better suited to large groups and health systems than solo or small practices. Pricing is not published and requires a sales conversation.

The Most Important Factor
The billing company matters less than the individual biller assigned to your account. Any company can claim behavioral health expertise. What you need to know is whether the specific person handling your claims has billed IOP, understands carve-out routing for your payers, and knows 42 CFR Part 2.
Ask for that information specifically before you sign anything.
At Dr. Billerz, you interview the biller before the engagement starts. You know exactly who is working your account and what they know before a single claim goes out.
Start the 4-week free pilot and see the results before you commit. Or book a 15-minute call to discuss your behavioral health billing situation specifically.
Frequently Asked Questions
Does my billing company need to sign a BAA for behavioral health?
Yes. Any entity handling PHI on your behalf must sign a Business Associate Agreement. For SUD treatment specifically, you should also discuss how they handle 42 CFR Part 2 requirements in their billing workflows.
What EHR systems are most common in behavioral health?
Kipu Health and Procentive are widely used in SUD and IOP/PHP settings. TheraNest and SimplePractice are common in outpatient mental health. AdvancedMD and Kareo appear across both. Make sure any biller you work with has direct experience in your specific platform.
Can a general medical billing company handle behavioral health?
They can attempt it. Most will get the outpatient therapy claims right and struggle with IOP/PHP billing, carve-out routing, and 42 CFR Part 2 compliance. The errors are often invisible until claims start denying in patterns. By then you’ve lost 60 to 90 days of revenue.
Is behavioral health billing more expensive than general medical billing?
Specialty billing generally runs at the same rate as general billing when priced hourly. Percentage-based companies may charge slightly higher rates for behavioral health due to claim complexity. The dedicated staffing model prices by the hour regardless of specialty.
