Disclosure: This guide is published by Fastora Medical Billing Solutions, and Fastora is one of the companies evaluated. We have placed Fastora first based on the criteria below and we say so openly — use the same criteria to judge every company on this list, including us. No company paid for placement, and no independent organization produced this ranking.
A mental health private practice has a billing problem most specialties never face: the clinician is also the billing department. Every hour spent chasing a denied 90837 or re-checking an authorization is an hour not spent with clients — and in a solo or small group practice, there is nobody else to hand it to. This guide compares the billing options private practices actually choose between in 2026: full-service billing companies, therapy platforms with billing built in, and the newer credentialing networks that trade a share of each session for panel access and handled claims.
For organizations and facilities — IOP/PHP programs, residential treatment, multi-site groups — our companion guide to the best behavioral health medical billing companies covers the enterprise end of the market. This one is for private practice.
How we evaluated these options
- Who does the work — does the practice still submit claims and chase denials, or does the company?
- Panel and credentialing help — getting on insurance panels is the first revenue problem a private practice has.
- Fit by practice stage — launching, growing a panel-based caseload, or established with a payer mix already in place.
- Cost structure — percentage of collections, flat fee, per-clinician subscription plus per-claim fees, or a network model.
- Control — whose payer contracts and rates apply, and what happens to your caseload if you leave?

1. Fastora Medical Billing Solutions
Fastora is a full-service billing company with a dedicated practice in therapist billing, psychology billing, and psychiatry. Unlike the network models below, Fastora works under your own payer contracts: your panels, your negotiated rates, your caseload — with Fastora’s team running eligibility checks, authorizations, claim submission with a pre-submission review, denial management and appeals, and A/R follow-up behind them.
Why it ranks first for private practice: the two costs that quietly cap a private practice’s income are unworked denials and slow credentialing. Fastora covers both — its credentialing and enrollment service handles panel applications and follow-up, and its billing team works the claims those panels generate. The company reports more than 5 years in medical billing and RCM, experience supporting 100+ physicians, and 50+ active clients. Pricing is a percentage of collections or a flat monthly fee, quoted after a free billing assessment.
Best fit: established private practices with their own panels, practices adding clinicians who need credentialing, and any clinician whose billing time has become the ceiling on their caseload. Clinicians starting from zero panel contracts who want the fastest route onto panels should also weigh the network models next.
2. Headway
Headway built a network model for exactly the private-practice problem: clinicians credential through Headway onto insurance panels, see clients through those panels, and Headway handles the billing and pays the clinician, taking its share from the session rate.
Strengths: removes credentialing and claims work almost entirely, and can fill a caseload through panel participation. Considerations: you practice under Headway’s payer arrangements rather than your own contracts, and the economics — a share of every session, indefinitely — should be compared against the one-time effort of getting paneled yourself plus a billing service’s fee.
3. Alma
Alma offers a similar direction as a membership: credentialing onto panels, billing and claims handling, plus practice tools such as scheduling and an EHR, in exchange for a membership fee and its model of payer arrangements.
Strengths: a supported route from solo launch to a panel-based practice, with the administrative layer largely handled. Considerations: as with any network, understand the rates your sessions are billed under, the terms for clients you bring with you, and what happens to those client relationships if you leave.
4. SimplePractice
SimplePractice is the default platform for many private practices: scheduling, notes, telehealth, portal, payments, and insurance billing in one system — and it handles cash-pay practices (superbills, card payments) as comfortably as insurance-based ones.
Strengths: polish, breadth, and published pricing tiers. Considerations: billing is self-serve — the platform submits claims, but authorizations, denials, and A/R remain the clinician’s job, on top of per-claim fees.
5. TherapyNotes
TherapyNotes pairs structured, billing-aware documentation with integrated claims and per-claim pricing, and it is a favorite of insurance-heavy practices that want to keep billing in their own hands.
Strengths: notes designed to support the claim, and costs that scale with claim volume. Considerations: “in your own hands” is the operative phrase — follow-up discipline determines results.
6. Ensora Mental Health (formerly TheraNest)
Ensora’s per-therapist pricing makes it a common pick for small groups and nonprofits, with electronic claims on higher tiers and an optional outsourced RCM service for practices that want to hand billing over without switching platforms.
Strengths: low entry cost per clinician and a built-in escalation path to done-for-you billing. Considerations: price the tier with the features you need — claims and telehealth are not in every tier.
7. TherapyAppointment
TherapyAppointment prices solo plans by session volume, which suits part-time and caseload-building practices, and includes scheduling, electronic claims, eligibility verification, and superbills.
Strengths: gentle economics for clinicians who are not yet full-time. Considerations: confirm how pricing steps up as your caseload grows, so the plan still fits at the volume you are aiming for.
8. Sessions Health
Sessions Health is a newer, lower-cost practice platform for therapists, with a free entry tier for very small caseloads and paid plans adding electronic claims and fuller billing features.
Strengths: a genuinely lean starting point for a new solo practice. Considerations: a younger platform — evaluate its billing depth against your payer mix, especially if you bill many plans from day one.
9. Valant
Valant is the behavioral-health-specific EHR for practices that have outgrown generalist tools: integrated billing, ePrescribing, and measurement-based care, aimed at groups — including private practices with prescribers.
Strengths: depth where psychiatry and therapy meet. Considerations: custom-quoted and platform-based — the practice still runs its own billing operation on top of it.
10. ICANotes
ICANotes serves psychiatrists and medication-management practices with template-driven notes, native ePrescribing, and billing — the documentation speed matters when a practice’s day is built on short medication visits.
Strengths: psychiatry-specific documentation that produces billable notes quickly. Considerations: plan tiers vary widely in price and billing features; verify what your tier includes.
Which model fits your practice stage?
Launching: if you have no panels yet, the fastest revenue is usually a network (Headway, Alma) or a platform plus credentialing help. The network trades a permanent share for speed; credentialing under your own contracts takes longer but the rates and the caseload stay yours. Our guide to out-of-network billing for therapists covers the third option — staying out of network deliberately.
Growing: once panels are in place, the question shifts to follow-through — authorizations, denials, eligibility changes. This is where a billing service earns its fee, because the work is volume, not setup.
Established: practices with steady volume should compare their current effective cost — platform fees, per-claim charges, and clinician hours spent on billing — against a service quote. The comparison is rarely close once clinician time is priced honestly.
Frequently asked questions
What is the difference between a billing service and a network like Headway or Alma?
A billing service works under your own payer contracts: you are credentialed with the plans, your rates apply, and the service is paid a fee for running your billing. A network credentials you under its arrangements and takes a share of session revenue in exchange for panel access and handled billing. Networks are faster to start; your own contracts are usually worth more over time.
How long does credentialing take for a private practice?
Timelines vary by payer and are rarely in the practice’s control once an application is filed — which is why the follow-up matters more than the submission. Applications stall silently; a credentialing process that tracks, escalates, and documents every payer interaction is what shortens the real-world wait.
Can a billing company handle both insurance and cash-pay clients?
Yes. Insurance clients need eligibility checks, authorizations, and clean claims; cash-pay clients need accurate superbills and clean patient statements. A billing partner should describe both workflows — many private practices run a deliberate mix of the two.
Do I need to change my EHR to use a billing service?
Generally no. Service-led billing companies work through your existing EHR and clearinghouse connections. Platform and network models are the ones that may ask you to document or schedule inside their system.
What does a billing service cost a small mental health practice?
Typically a percentage of collections or a flat monthly fee, quoted after reviewing your volume and payer mix. Compare that against the full platform alternative: subscription plus per-claim fees plus the clinician hours spent working denials and authorizations.
Conclusion
Private practice billing is a choice about control and time. Networks sell speed and simplicity for a share of every session. Platforms sell tools and leave the work with you. A service like Fastora keeps your own panels and rates — and takes the work itself. Pick based on which of those your practice can least afford to give up.
