# June 22, 2026 — Insurance billing date restriction

> OON Pay and Thrizer Pay charges now require a Date of Service that is today or tomorrow. Sessions further in the future must use Self-Pay.

## Updates

### Insurance billing restricted to current or next-day sessions

OON Pay and Thrizer Pay are now only available when the Date of Service is **today or tomorrow (UTC)**. Sessions two or more calendar days in the future can no longer be billed to insurance through Thrizer.

What this means for you:

* In Add Charge, picking a date more than one day ahead disables OON Pay and Thrizer Pay in the payment type dropdown and switches the form to Self-Pay.
* An OON Pay or Thrizer Pay charge with a missing date, or a date more than one day ahead, is not accepted.
* **Self-Pay accepts any future Date of Service** and is the supported option for advance billing.
* To bill insurance, create the charge on the day before or the day of the session.

See [Payment types and eligibility](/help/clinician/payment-types-and-eligibility) and [Claim and billing limitations](/help/claims/claim-and-billing-limitations) for the full rules.
