Submit prior authorization

Last updated: Feb 18, 2025

You can use this API action to complete prior authorization, pre-approval, or pre-certification before offering healthcare services or prescriptions. The intent of prior authorization is to confirm that the payer intends to pay for a high-cost service or prescription before it’s provided.

To find out if your request is approved, your connection would receive and respond to prior authorization requests.

Prior authorization terminology

You may see words like prior authorization and preauthorization used interchangeably. Similar to data exchange, the industry hasn’t standardized on one term for this process, so you may see different phrases, but they mean the same thing.

Use cases

This API action may be a good fit for your organization if you perform any of these use cases:

Confirm that the patient's insurance company will cover treatment.
Check if a payer will pay for a prescription before writing a prescription.
Get approval from the patient’s insurance company before:
- scheduling a patient's surgery;
- ordering durable medical equipment (e.g., braces, prosthetics) for a patient;
- ordering implantable medical devices (e.g., pacemaker) for a patient; or
- referring a patient to another level of care.

Check out our case study for more details about the problems you can solve with this API action.

Supported systems

You can use this API action with the Redox FHIR® API.

Your connection's system can receive claims with their own query-based API that can also exchange X12. Responses to prior authorization requests can be either synchronous or asynchronous, depending on your connection’s capabilities.

Submit a medication prior authorization request

There are two types of prior authorization requests. Prescription requests allow you to receive approval for prescribed medication. Service requests allow you to receive approval for procedures, referrals, or medical equipment.

This table has notes about how to use parameters for this API action specifically, but it's not exhaustive. Refer to the Claim schema for more details.

Parameter	Required	Notes
entry	Y	This is where you include a MedicationRequest resource to indicate which kind of prior authorization request you're submitting. You must also include resources for Claim, Patient, Organization, Coverage, at a minimum. You may include other relevant resources to give context for your claim.

Don't forget that the response may be either synchronous or asynchronous, depending on your connection's capabilities.
