Invoice rejected for missing authorization: how to recover revenue
A rejected invoice points to an operations issue, not an accounting one
When the insurer returns the invoice with "no authorization" or "expired authorization", the problem is rarely accounting. It usually sits in how the authorization was requested, linked to the act or tracked for validity.
Calculate revenue lost to authorisations
Use the SaludComply authorisation diagnostic to estimate monthly loss, recoverable range and operational complexity. No patient data required.
What to document before disputing
Gather prescription, original authorization number, request date, approval date, service date, billing date and literal rejection reason. If the act was performed within the valid window, the dispute is reasonable.
Which invoices to dispute and which to archive
Dispute first invoices with valid authorization at service time. Then recent expiries with the procedure done. Archive cases with no prior authorization where one was required.
How SaludComply prevents the invoice coming back rejected
SaludComply keeps the authorization number linked to patient, act and appointment date from approval. It alerts before expiry and flags approved-but-unbilled authorizations.
Frequently asked questions
- Why does the insurer reject an invoice for missing authorisation?
- When the insurer returns an invoice with "no authorisation" or "expired authorisation", the problem is rarely in billing: it usually sits earlier, in how the authorisation was requested, how it was linked to the performed act, or how the validity date was tracked. Treating it only as a collection incident leaves the root cause intact and the next invoice comes back the same.
- What should be documented before disputing a rejected invoice?
- Gather the prescription, the original authorisation number, the request date, the approval date, the service date, the billing date and the literal rejection reason. If the authorisation existed and the act was performed within its window, the dispute is reasonable and the insurer usually only asks for clarification. If it had expired or was performed with a different code, the outcome depends on the insurer, the history and the value of the case.
- How does SaludComply prevent the invoice from coming back rejected?
- The agent keeps the authorisation number linked to patient, act and appointment date from the moment of approval, alerts before expiry and flags approved-but-unbilled authorisations. When the invoice is issued, the relevant data is already checked; if it should not yet be issued, the system flags it. Every action is held for human approval.
