Session-Based Billing for Therapy Practices: A Practical Guide

Session-based billing is a model where each completed therapy session creates its own charge. The charge reflects the session type, length, clinician and payer.

It suits individual, couples, family and group therapy. Each can have its own price and rules.

The model is simple to explain to clients. They know what each session costs and what they still owe.

It also gives the practice clear data. Leaders can see sessions delivered, sessions billed and payments collected for each clinician and service.

The gap between those three numbers shows exactly where revenue is leaking.

Set it up by defining your services and rules first, then connecting them to scheduling and payments. Follow these steps:

1. List each session type, such as individual, couples, family, group and assessment.
2. Set a KES price and standard length for each type.
3. Decide your rules for packages, deposits, late cancellations and missed sessions.
4. Record each client's payer: self-pay, SHA, employer scheme or private insurer.
5. Link each appointment to its service so a charge is created when the session is completed.
6. Collect payment or confirm cover at the point of service.
7. Reconcile all payments against sessions at the end of each day.

Therapy practices should treat packages and deposits as prepaid credit linked to the client's account. Each completed session then draws down the balance.

Show clients their remaining balance after every session. This avoids surprises and builds trust.

Write down what happens to unused sessions and refunds. Apply the rule consistently, with an approval step and audit trail for every refund.

Some practices offer reduced fees or sliding scales. Record the agreed rate on the client's account, with the reason and approver, so it is applied the same way every time.

Group sessions need their own logic. Each attendee should receive a charge, and absent members should follow your stated cancellation rule.

Claims work best when cover is checked before therapy starts and each session is documented to the payer's requirements. Check whether the client's scheme covers mental health services and how many sessions are allowed.

Track pre-authorisation and session limits on the client's account. Alert staff before the limit is reached, so the client can plan.

Common claim problems include:

• Expired pre-authorisation or exceeded session limits.
• Missing or inconsistent client details.
• Services billed under the wrong code or category.
• Notes not signed before the claim is submitted.

The Social Health Authority (SHA) replaced NHIF in October 2024. Review its current mental health benefits regularly, as rules can change.

Kenyan practices manage M-Pesa payments best by using a paybill or till with an account reference linked to the client's invoice. Payments can then be matched automatically.

Send the payment request or details by SMS before or after the session. Many clients prefer to pay discreetly on their phone rather than at reception.

Issue a receipt immediately, and use KRA eTIMS-compliant invoices where required. Our guide to reconciling clinic payments across M-Pesa, cash, card and insurance explains the matching process.

Keep privacy in mind. Payment descriptions should not reveal the nature of the service, because health data is sensitive personal data under the Data Protection Act 2019.

The most common mistake is relying on memory to record which sessions were delivered. Unbilled sessions add up quickly.

Other mistakes to avoid:

• Unclear cancellation rules that lead to disputes.
• Discussing balances in the session itself, which can harm the therapeutic relationship.
• Giving therapists access to financial detail they do not need.
• Reconciling payments monthly instead of daily.

Separate the money conversation from the therapy room where possible. A front desk or finance contact can handle balances, so the clinician does not have to.

Let the system handle billing prompts, so clinicians can focus on care. Explore more in our guide to what a mental health EHR should include.

What is the difference between session-based and package billing?

Session-based billing charges each session as it happens. Package billing takes payment upfront for several sessions and draws down the balance as each one is completed.

Should therapists charge for missed sessions?

That is a practice policy decision. If you charge, explain the rule clearly in writing before therapy starts and apply it consistently, with discretion for genuine emergencies.

Does SHA cover therapy sessions?

Cover depends on current SHA benefit packages and facility contracts. Check eligibility for each client before therapy starts and review SHA guidance regularly.

How can clients pay for therapy discreetly?

Offer M-Pesa payment links or paybill details by SMS, with neutral payment descriptions. Clients can pay privately without discussing money at reception.

How often should a practice reconcile therapy payments?

Daily. Matching each payment to a session every day catches errors early and makes month-end reporting straightforward.
