Prior Authorization Tips That Prevent Costly Denials

A denial for a missing prior authorization is one of the most frustrating in medical billing. The service was performed and documented, but the payer will not pay because approval was not obtained first, and many of these denials cannot be appealed successfully.

Where authorizations go wrong

• The front desk does not know which services need authorization for which payer.

• The authorization was obtained, but for a different code, date range or number of visits.

• An authorization expired before a follow-up visit or procedure.

• Nobody confirmed the approval before the patient arrived.

Five steps to prevent authorization denials

1. Keep a payer authorization matrix. List which services require authorization for each major payer, and update it whenever payer policies change.

2. Check at scheduling, not check-in. Start the authorization process when the appointment is booked, so there is time to get approval.

3. Match the details exactly. Confirm the CPT codes, units, dates of service and rendering provider on the approval match what will be billed.

4. Track expiry dates and visit counts. Flag authorizations that are close to expiring or running out of approved visits.

5. Record everything. Save the reference number, the payer contact and the date of approval with the patient’s account.

Every authorization secured before the visit is a denial you never have to work.

Conclusion

Prior authorization is a front-end task with back-end consequences. A consistent process at scheduling protects revenue and spares patients from surprise bills.
