Mental Health Billing Services in California

You care for your patients. We care for your billing.

Professional Billing Services for Mental Health Providers

Mental health providers give life-changing support therapy, assessments, medication management, crisis care, and more. But behind every session, there’s billing, prior authorizations, documentation, CPT coding, modifier requirements, and payer rules that change constantly.

Most mental health providers tell us the same things:

That’s exactly what Claim N Billing does for you.

We specialize in billing for psychiatrists, psychologists, therapists, LCSWs, LMFTs, and behavioral health clinics – making sure your claims get paid fully and on time.

What Is Mental Health Billing?

Mental health billing involves submitting claims for therapy sessions, evaluations, medication management, and behavioral health services each requiring correct CPT codes, authorization tracking, clinical documentation, and payer-specific rules.

Compared to general medical billing, mental health billing is more complex because:

Time-based CPT codes require exact documentation
Modifiers vary by insurer
Telehealth coverage constantly changes
Progress notes must meet medical necessity standards
Prior authorizations are often required

We take over the entire billing burden so you can stay focused on patient care.

Why Mental Health Providers Choose Claim N Billing

Experts in psychiatry & therapy billing
Knowledge of payer-specific documentation standards
HIPAA-compliant systems ensure full data protection
Real-time claim tracking and monthly reporting
Understanding of California’s Medi-Cal mental health rules
Transparent communication & a dedicated billing specialist

We don’t just submit claims – we actively manage your revenue cycle.

Why Mental Health Billing Services Matter

Mental health providers are often overwhelmed by the billing side of their practice. Common pain points include:

High denial rates
Incorrect CPT codes, missing modifiers, or insufficient documentation cause frequent denials.
Insurance rules constantly change
Telehealth coverage, time-based rules, and PA requirements vary by payer.l.
Paperwork reduces patient time
Providers lose 6–10 hours per week managing administrative work.
Delayed payments hurt practice cash flow
Denied or ignored claims delay payment for weeks or months.
Eligibility & authorizations slow down scheduling
Missing verifications make it harder to accept new patients.

Our billing support removes every one of these barriers so your practice can grow without interruptions.

The Services We Provide

Claim Submission & Follow-Up

This is where your revenue actually starts moving.

Once care is provided, claims have to be created correctly, submitted on time, and actively followed, not sent out and forgotten. That’s the work we handle every day.

We take responsibility for turning your visits into clean, accurate claims and staying on top of them until there’s a clear response from the payer.

What this includes:

Accurate claim creation and submission
Verification that payer and provider details are correct before submission
Timely filing to avoid avoidable denials
Ongoing claim tracking after submission
Follow-up with payers until claims are processed
Correction and resubmission when issues arise

Denials Management & Appeals

This is where most revenue is quietly lost, and where we’re the most hands-on.

A denial isn’t the end of a claim. It’s a signal that something further upstream needs attention.

We work every denial until there’s a real payment or a clear reason why not, and then we go back and fix whatever caused it in the first place.

How we protect your revenue:

Root-cause review of every denial, not just resubmission
Correction of coding, modifier, and eligibility errors
Medical necessity documentation compiled and submitted
Appeals written and pursued when payment is owed
Secondary and corrected claims handling
Denial trend reporting so the same issue stops repeating

Prior Authorizations

Most practices don’t realize how much revenue they lose from missing or incorrect authorizations, until it’s too late.

We step in early to prevent those losses.

What we handle:

Identifying services that require authorization
Catching recurring denial patterns tied to auth issues
Submitting and following up on authorizations
Managing appeal documentation when needed
Rebilling and recovery when claims are incorrectly denied

Credentialing

Credentialing isn’t just paperwork — it directly impacts whether you get paid at all.

We handle credentialing with the same attention we give claims, because front-end mistakes cause most downstream denials.

Our role includes:

Appointment Setting

Medical billing works best when the schedule and the claim always tell the same story.

We handle the front-end coordination that keeps your calendar full and makes sure every visit that happens is a visit that can be billed.

What this supports:

New patient scheduling with insurance verified upfront
Reminder workflows that reduce no-shows and cancellations
Recurring and follow-up visits booked on schedule
Fewer missed or delayed charges
Scheduling, documentation, and claims kept aligned

Monthly Financial Reporting

You shouldn’t have to guess how your practice is performing, or where your money stands.

We provide clear visibility into what’s happening, what’s pending, and what needs attention.

You receive insight into:

Payment Posting & Reconciliation

Accurate payment posting matters just as much as claim submission.

We make sure payments, adjustments, and write-offs are correctly reflected, so your numbers tell the truth.

This includes:

ERA and EOB posting
Payment and adjustment reconciliation
Underpayment identification against contracted rates
Patient responsibility balances and statements
Write-off accuracy and audit readiness support

Our services are designed to support practices at different stages, whether you need help in one area or across your entire billing workflow.

Consultation & Account Setup

We review your services, codes, and pain points to build your billing profile.

Insurance Verification

We confirm patient mental health coverage before appointments.

Claim Submission

We submit compliant claims with correct coding, modifiers, and documentation links.

Payment Posting

We record payments and flag underpayments, denials, and discrepancies.

Reporting & Ongoing Support

You receive monthly insights into revenue, denials, and performance.

Mental Health Insurance & Medi-Cal Expertise

Mental health services have some of the strictest payer policies. Our team stays on top of:

We ensure your claims meet all medical necessity and documentation standards.

Client Success Stories

Our results speak for themselves – see how we’ve helped mental health providers streamline billing and get paid faster

I run a four-clinician practice, and our denial pile was mostly authorization lapses and time-based coding that didn't match the note. They built an eligibility and auth check into our intake so we catch it before the session, not sixty days after. They also got two of my associates paneled with plans I'd been trying to join since I opened. Collections are steadier month to month, which matters more to me than any single big number.

Frequently Asked questions

Who does mental health billing in Orange County?

Claim N Billing has been doing behavioral health billing from Irvine since 2016. We bill for psychiatrists, psychologists, LCSWs, LMFTs, and group behavioral health practices across Orange County, Los Angeles, and the Inland Empire. We work Medi-Cal county mental health plans alongside commercial payers, which is where most general billing companies stop.

How much does mental health billing cost?

Claim N Billing charges 5 to 8 percent of collections with a $200 monthly minimum, plus a $200 monthly admin fee that is waived once your monthly invoice reaches $5,000. That covers claim submission, prior authorization tracking, denial appeals, payment posting, and monthly reporting. Credentialing is quoted separately.

Do you bill for solo therapists or only group practices?

Both, and solo practitioners are a large part of what we do. There is no minimum claim volume. A solo therapist billing 60 sessions a month gets the same dedicated specialist as a ten provider group. The $200 monthly minimum exists so that is actually possible rather than a promise nobody keeps.

Do you handle credentialing for therapists?

Yes. We handle commercial panel applications, CAQH setup and re-attestation, Medi-Cal enrollment through PAVE, and managed care plan credentialing. This is quoted separately from billing because the work is front loaded. Most therapists who come to us with a revenue problem turn out to have a credentialing problem, so we usually check that first.

Do you work with SimplePractice, TherapyNotes, or our existing EHR?

Yes. We work inside whatever system you already use rather than making you migrate. That includes SimplePractice, TherapyNotes, Kareo, and the larger platforms. What matters more than the specific software is whether we get direct access or work from exported reports, and direct access is always better because export based workflows create delays and blind spots.

What CPT codes do therapists use for billing?

The core set is 90791 for a diagnostic intake, 90832 for roughly 30 minutes of individual therapy, 90834 for roughly 45 minutes, 90837 for 60 minutes or more, 90846 and 90847 for family therapy without and with the patient present, and 90853 for group therapy. Psychiatrists billing medication management use evaluation and management codes, with an add on therapy code when both are provided.

Why do insurance companies deny 90837?

Because it pays more than 90834 and payers watch for overuse. The usual causes are missing time documentation, a note that does not establish why the longer session was clinically necessary, billing 90837 for nearly every client on the panel, or a plan that requires prior authorization for extended sessions. Documenting actual session minutes and the reason for the length resolves most of it.

Does Medi-Cal cover therapy in California?

Yes, but the route depends on severity. Mild to moderate conditions are generally covered through the member’s Medi-Cal managed care plan. More severe conditions run through the county mental health plan under specialty mental health services. Billing the wrong entity is a frequent denial cause, so confirm which one holds the member’s behavioral health benefit before submitting.
