Mental & Behavioral Health Billing Services

Mental health billing has its own payers, its own rules, and its own ways of losing money. The plan on a client’s card often hands mental health claims to a separate administrator. Medicaid sends most members through managed care plans that each credential on their own timeline. A group practice can have a psychiatrist, a nurse practitioner, three counselors, and a social worker who are each in network with a different set of plans. Maximum Billing, LLC provides mental and behavioral health billing services for practices in twelve states, working inside the software you already use.

What Our Mental Health Billing Services Cover

Coverage checks that look past the card: which entity actually pays for mental health services, whether a referral or authorization is needed, and how many visits the plan allows.
Claims built for the payer that pays them, with the right rendering clinician, place of service, and modifiers for that plan.
Remittance posting by clinician and by payer, so a group can see which plans pay which providers, and at what rate.
Denials worked to the cause, appealed when the plan was wrong, and tracked so the same denial stops repeating.
Follow-up on every open claim until it is paid or resolved.
Client statements and balance questions, handled with the care a therapeutic relationship needs.
Credentialing and enrollment for each clinician with each plan the practice accepts.

Behavioral Health Carve-Outs: Who Really Pays the Claim

Many commercial and Medicaid plans do not manage mental health benefits themselves. They contract them out to a managed behavioral health organization, which runs its own network, its own authorization rules, and its own claims address. A claim sent to the medical plan on the card can be denied even when the client has full coverage, simply because it went to the wrong place.

We confirm where each client’s mental health benefit sits before the first session. When a client changes plans, or an employer changes administrators at renewal, we catch it at the next eligibility check instead of after a month of denials.

Mental Health Parity and Why It Matters for Billing

The federal Mental Health Parity and Addiction Equity Act generally bars group health plans and insurers from putting stricter limits on mental health and substance use disorder benefits than on medical and surgical benefits. That covers financial requirements like copays and visit limits, and it also covers treatment limits like prior authorization rules.

Parity does not mean every claim gets paid. It does mean a denial or a limit that would not apply to a comparable medical service is worth questioning. When a pattern of denials or authorization demands looks out of line, we document it and appeal on that basis.

Medicaid and Managed Care

Medicaid is a large share of mental health care, and it is billed differently in every state. Most states enroll members in managed care plans, and many of those plans use a separate behavioral health administrator. A practice usually needs to be enrolled with the state Medicaid program first and then credentialed with each managed care plan it wants to see clients from. Some programs also require treatment plans, authorizations, or specific clinician qualifications before a service can be billed.

Our state guides walk through enrollment step by step:

Billing for a Practice With Many Kinds of Clinicians

The billing gets harder as a practice grows. Each license type is credentialed and reimbursed on its own terms, and a plan that pays one clinician may not have the next one in network at all. In a mixed group, we keep a clinician-by-payer map of who is in network where. That way, intake can match clients to clinicians whose claims will actually pay, and new hires are credentialed before their schedules fill. Our group practice billing page covers enrollment, linking, and Medicare reassignment for groups.

Therapists and counselors bill session codes by time, often with telehealth rules that vary by plan. Our therapy billing services page covers the codes therapists use most.
Psychiatrists and psychiatric nurse practitioners bill evaluation and management visits, often with psychotherapy add-on codes. See our psychiatric billing services.
Practices that are out of network with some plans need benefit checks, claims, or superbills for those clients. See our out-of-network billing services.

Where Mental Health Practices Lose Revenue

Claims sent to the medical plan when the mental health benefit is carved out.
Sessions seen after an authorization ran out or a visit limit was reached.
A clinician seeing clients from a plan they were never credentialed with.
Medicaid managed care claims denied because the practice was enrolled with the state but not with the plan.
Small balances and secondary claims that nobody had time to bill.
Denials that were resubmitted unchanged, or never worked at all.

Our claims denial management and accounts receivable management services explain how we recover what is still collectible.

Mental Health Billing by State

Each state has its own Medicaid program, managed care plans, and payer mix. Our state pages cover the details for Colorado, Connecticut, Florida, Georgia, Illinois, Missouri, New Jersey, New York, North Carolina, Pennsylvania, South Carolina, and Texas.

Credentialing Comes First

A claim cannot be paid for a clinician who is not enrolled with the plan, however clean it is. We handle CAQH profiles, commercial plan applications, Medicare enrollment, and state Medicaid and managed care enrollment, and we track revalidation dates so enrollment does not lapse. See our mental and behavioral health credentialing services.

Software, Privacy, and Results

We work inside the system you already use, including SimplePractice, Sessions Health, TherapyNotes, and InSync. Mental health records carry some of the most sensitive information in health care. We sign a Business Associate Agreement with every client before any information is shared, and every team member completes HIPAA certification. Our HIPAA compliant billing services page explains how we protect it.

As of 2026, our clients’ claims reach a 91% clean claim rate, and their accounts receivable average 34 days.

Frequently Asked Questions

What is the difference between mental health billing and behavioral health billing?

In practice, very little. “Behavioral health” is the broader term and usually includes substance use services along with mental health care. Payers and administrators use both terms, and we bill for practices that describe themselves either way.

Why was a claim denied when the client has insurance?

Often the mental health benefit is managed by a separate administrator, the clinician is not in network with that administrator, or an authorization or visit limit was missed. We check all three before the first session.

Do you bill Medicaid managed care plans?

Yes. We bill Medicaid and its managed care plans in the twelve states we serve, and we handle the state enrollment and plan credentialing that comes first.

Can you take over billing for a group with several types of clinicians?

Yes. We bill for counselors, therapists, social workers, psychologists, psychiatrists, and psychiatric nurse practitioners in the same practice, and we track each clinician’s network status with each plan.

Do we have to change our EHR?

No. We work inside the practice management system you already use.
