Therapist Billing Services: What a Billing Company Handles
Therapist billing services are the back-office work a billing company does so a therapist or psychiatrist can get paid by insurance: checking benefits, sending claims, following up on denials, and posting payments. This guide shows what that work covers, what still belongs to your practice, and how to compare options. It is written for solo and group practice owners in mental and behavioral health.
What do therapist billing services include?
Most therapist billing services cover the steps between a finished session and a paid claim. The list below follows the order a claim travels.
- Insurance verification: confirm the plan is active and what it covers before the visit.
- Electronic claims submission: send a clean claim to the payer through a clearinghouse.
- Payment posting: match each payment and explanation of benefits to the claim.
- Denied and rejected claim follow-up: find the reason, fix it, and appeal when it makes sense.
- Secondary claims: bill a second plan after the first one pays.
- Insurance credentialing: get you enrolled with the payers your clients use.
- EAP claim processing: handle employee assistance program sessions, which follow different rules.
What stays with your practice?
A billing company cannot fix what happens in the session room. Your practice still owns clinical documentation, the diagnosis and the code that match what you did, and the signed consent and intake paperwork. A biller works from those records. If the note does not support the code, the claim is at risk no matter who sends it.
You also decide how you handle client balances and your own policies. Good billing services give you clear reports so you can see what was billed, paid, and denied.

How to compare therapist billing services
Ask every company the same questions so you can compare answers side by side.
- Do you work only in mental and behavioral health, or in every specialty?
- Will you sign a business associate contract? HIPAA generally requires a written contract with any business associate that handles protected health information (source: HHS, checked 10/21/26).
- Who sends claims, who follows up on denials, and how often do I get reports?
- How are you paid, and what happens if I leave? Read the pricing terms in writing.
- Can you handle in-network, out-of-network billing, and EAP claims?
