Overview

When a clinician creates an OON Pay or Thrizer Pay charge, the session’s Date of Service must be today or tomorrow. Charges dated more than one calendar day in the future are not allowed. This rule exists so Thrizer can accommodate clinicians who charge the day before a session, without ever submitting a claim to insurance for a session that has not yet happened.

Why does Thrizer allow tomorrow’s date at all?

Many clinicians have a practice policy of charging the client the day before the session. Thrizer supports that workflow. When a charge is created for tomorrow’s Date of Service, Thrizer holds the resulting claim for approximately 24 hours and submits it to insurance after the Date of Service has passed. The clinician can collect payment on their normal schedule, and the claim itself is never sent to insurance with a future date.

Why can’t I bill further than one day ahead?

Insurance carriers do not accept claims for dates of service that have not yet occurred. Submitting a claim for a session more than 24 hours in the future would either be rejected by the payer or misrepresent when care was delivered. To keep every submitted claim accurate, Thrizer blocks charges where the Date of Service is more than one calendar day ahead of the current UTC date.

What about no-shows or cancellations after I’ve already charged?

Because the claim is held for 24 hours before submission, there is a window to correct a charge if the client cancels or does not attend. If a session does not happen after a charge has been created, refund or adjust the charge as soon as possible. See Payments, payouts, and refunds for the refund workflow, and contact Support if you’re unsure whether the claim has already been submitted.

Does this rule apply to Self-Pay?

No. Self-Pay charges do not generate an insurance claim, so the Date of Service restriction that protects claim accuracy does not apply in the same way. The today-or-tomorrow rule is specific to OON Pay and Thrizer Pay, where a claim is submitted to insurance.
