What Information Is Needed for a Prior Authorization Request

Meeting prior authorization requirements with accurate patient details, clinical documentation, treatment history, and payer-specific forms helps reduce delays, prevent denials, streamline workflows, and improve patient access to medications and care.

Not the majority of prior authorization hold-ups occur due to the insurer being “slow.” Such hold-ups occur because of an incomplete submission on the very first try. It could be a matter of an attachment that is missing, of codes not matching, or even of an outdated form.

That’s why understanding Prior authorization requirements matters. Prior authorization requirements are the difference between a clean submission and a request that gets stuck waiting for “just one more document.”

The following guide describes what information usually goes into the Prior Authorization request, and how to prepare it in order to avoid delays, denials, and unnecessary effort on the part of your staff. A more thorough Prior Authorization request means more than a quicker process – it means better patient access.

Quick Refresher: What is Prior Authorization?

Prior authorization is insurer approval required before certain medications, treatments, or services are covered.

Who’s involved:

• Prescriber office (usually submits the request)
• Payor/PBM (reviews and decides)
• Pharmacy (often triggers the “PA required” message at claim)
• Patient (may need to provide info and follow up)

Why requirements vary:

Every payer and plan can have different policies, and requirements often change based on therapy category, diagnosis criteria, and benefit type (medical vs pharmacy).

What Information Is Needed for a Prior Authorization Request? (Main Checklist)

Here is the simple list most payers want. It’s not necessary that each claim include all the items, but lack of anything required will probably create problems fast.

1. Patient Information (Identity + Insurance Details)

This is the foundation. If the payer can’t confirm who the patient is and what plan they’re on, the request can’t move.

Typically required:

• Full name, date of birth, address, phone
• Member ID, group number, plan name
• Primary vs secondary insurance (if applicable)

Tip: Member ID errors are more common than people think, especially when coverage changes or a patient has multiple plans.

2. Prescriber Information

The payer needs to confirm who is ordering the therapy and how to contact them.

Typically required:

• Provider name, NPI, and sometimes tax ID
• Practice contact info (phone/fax/email)
• Specialty and location (sometimes required)

3. Medication or Treatment Details

This is where “close enough” can cause problems. Payers often evaluate criteria based on exact dosing, quantity, and days supply.

Typically required:

• Drug name (brand/generic), strength, dosage form
• Directions (SIG), quantity, days supply, refills
• Route of administration
• Start date and urgency (standard vs expedited)

Tip: Quantity and days supply mismatches are a common reason requests get pended.

4. Diagnosis and Clinical Rationale

This is the “why” behind the request, and it’s where many approvals are won or lost.

Typically required:

• Diagnosis (ICD-10 code)
• Symptoms and severity
• Duration of condition
• Why the requested therapy is medically necessary

Tip: Don’t assume the diagnosis code alone tells the story. Many payers want the clinical context that supports guideline alignment.

5. Supporting Clinical Documentation (Attachments)

If the payer’s criteria requires proof, you need to attach it. Missing documentation is one of the biggest delay drivers.

Common attachments:

• Chart notes and progress notes
• Lab results or imaging reports (if required)
• Test results tied to payer criteria
• Specialist consult notes (if applicable)

Tip: If a payer requires a specific lab value or test result, call it out clearly in the documentation instead of making the reviewer hunt for it.

6. Prior Treatment History (Step Therapy Proof)

Many plans require patients to try preferred alternatives first. If you don’t show that history, the request may be denied even if the therapy is clinically appropriate.

Typically required:

• Treatments tried but unsuccessful (names, dates, results)
• Adverse effects or contraindications
• Reasons that other treatments are not suitable

Tip: “Tried but unsuccessful” is more persuasive when it includes results and dates.

7. Safety and Risk Considerations (When Applicable)

Some medications require extra safety confirmation.

May include:

• Allergies
• Drug-drug interaction concerns
• Monitoring plans (for high-risk medications)

8. Payer-Specific Forms and Criteria Confirmation

An otherwise great clinical narrative may even be delayed because of the wrong document format.

It is important that you ensure that you have:

• The proper and up-to-date form of the payer
• All required boxes or attestations filled out
• The submission process and any reference numbers where applicable

The right Prior Authorization requirements met before submission will help avoid having your Prior Authorization request put on hold or denied.

(If you are using any workflow assistance tool such as RxEPA, then your aim should remain the same.)

Common Mistakes That Cause Delays (And How to Avoid Them)

Here are the most common “small mistakes” that create big slowdowns:

• Missing attachments
  • Fix: use a pre-submit checklist tied to each therapy type
• Wrong or outdated form
  • Fix: pull forms from the payer portal and assign ownership for updates
• Incorrect member ID or plan info
  • Fix: verify insurance details before submission
• Diagnosis mismatch with payer criteria
  • Fix: confirm criteria and document severity and rationale clearly
• Quantity or days supply mismatch
  • Fix: align prescription details with plan limits and criteria
• No documentation of prior therapies tried
  • Fix: include step therapy history with dates and outcomes

Tips to Speed Up Approvals (Simple Workflow Best Practices)

If you want faster approvals without adding more staff, focus on repeatable workflow upgrades:

• Use a payer-specific checklist
• Standardize templates for common therapies
• Validate codes and patient info before submitting
• Track status and respond quickly to payer requests
• Use electronic submission and status tracking when possible

A little structure upfront prevents a lot of rework later.

FAQs

1) How Long Does Prior Authorization Take?

It depends on the payer, therapy type, and whether the submission is complete. Many delays come from missing documentation or slow responses to payer requests for more information.

2) What Happens if My Prior Authorization Request Is Denied?

Your provider can often fix and resubmit if something was missing, appeal the decision (sometimes with peer-to-peer), or switch to a covered alternative when appropriate. Ask for the denial reason so the next step is targeted.

3) Can a Pharmacy Submit a Prior Authorization Request?

In many cases, the prescriber’s office submits the PA because clinical documentation is required. Pharmacies often help trigger the process, share payer messages, and coordinate next steps with the provider.

Conclusion:

Prior Authorization that needs no revision is the quickest.

A comprehensive submission usually entails: patient information, prescriber information, therapy information, diagnosis/rational, documents, prior treatments, and the right payer form.

Understanding the Prior Authorization requirements will help avoid delays and rejections. A comprehensive Prior Authorization request, on the other hand, will speed up the process and improve patient access without endless follow-ups.
