Outsourcing insurance billing frees hours every week and usually collects more than doing it yourself, if you pick the right company. We compared 13 mental health billing services and picked the 7 best for therapists, from solo practices to group practices, with what each one actually charges.
How we chose: we compared 13 billing services on what each company publishes on its own website, checked November 1, 2026: pricing, who it is built for, and what is included. We ranked them on those facts for a therapy practice. We have not used every one, so we do not claim to have tested them. No company paid to be listed or for its place, and any partner link is marked as one.

How much does a mental health billing service cost?
Most charge a percentage of what they collect. Among the companies that publish a rate, it runs from 4.5% for a large group to 8% for a solo practice, often with a monthly minimum. A practice that collects $150,000 a year from insurers pays about $7,000 at 4.75%, $9,000 at 6% and $10,500 at 7%. A good service usually pays for itself by collecting more, through fewer denied claims and faster follow-up, rather than by being cheaper.
How to choose a billing service
- Is the percentage of what you bill, what is collected, or what the insurer allows?
- Is there a monthly minimum, a setup fee or a per-provider fee?
- How long is the contract, and what does leaving cost?
- Who chases denials and appeals, and how quickly?
- Do they work in your EHR, or need logins to theirs?
- Do they bill your insurers, including Medicaid and Medicare if you take them?
- What reports will you see each month?
