How to Choose a Prior Authorization Service in 2026

Outsourcing prior authorization is one of the highest-leverage decisions an independent practice will make this year — but not every vendor delivers what their website promises. Use this checklist to compare prior authorization services apples-to-apples before you sign anything.

1. HIPAA compliance, in writing

Every reputable PA service will sign a Business Associate Agreement (BAA) before they touch a single chart. Ask for it on the first call. If a vendor hesitates, that's your answer.

2. Published approval rate (and how they measure it)

First-pass approval rate is the single best quality metric. Anything below 85% means denials and rework will land back on your staff. Ask whether their number is first-pass or post-appeal, and whether it's measured per-payer or in aggregate.

3. Specialty-specific playbooks

Orthopedic MRI criteria don't look like cardiology echo criteria, and neither look like specialty infusion. A vendor that handles your specialty every day will know each payer's medical-necessity language by heart — and it shows up in your turnaround time.

What to look for in a checklist

• Signed BAA and documented HIPAA training for every assigned specialist.
• First-pass approval rate ≥ 90% with monthly reporting.
• Named specialist assigned to your account — not a rotating pool.
• Average turnaround under 48 hours on standard requests.
• Eligibility verification included, not billed separately.
• Daily payer follow-up cadence with escalation rules.
• Peer-to-peer scheduling handled end-to-end.
• EHR-agnostic — works inside your existing workflow.
• Transparent pricing: per-request, per-provider, or flat monthly.
• Month-to-month contract option, not 12-month lock-in.

Red flags to walk away from

• Won't share an approval rate — or quotes 100%.
• Requires shared logins instead of named user access.
• No documented denial-management or appeals process.
• Pricing only available after a sales call.
• Offshore staffing with no US-based clinical reviewer.

Pricing models, decoded

Per-request pricing rewards efficiency and is easy to budget against denial savings. Per-provider monthly pricing is predictable but penalizes low-volume months. Flat enterprise pricing usually only makes sense above 500 requests/month. Whichever model you pick, calculate cost per approved authorization, not cost per submission.
