Prior Authorization Is Harming Patients: 9 in 10 Face Delays, Denials, and Higher Costs

Prior Authorization Is Delaying Care: What Your Insurance Team Can Fix Now

From a sample of 300 cases, prior authorization created measurable patient harm. The signal is clear and consistent.

• Treatment delay: 96%
• Diagnostic imaging delay: 94%
• Forced switch to second-choice therapy: 93%
• Higher out-of-pocket costs: 88%
• Therapy denial: 87%

Why this matters to payers and UM leaders

Delays drive adverse outcomes, grievances, and appeals. They also risk penalties under emerging rules and erode provider relationships.

Faster, clearer decisions reduce total cost of care and abrasion. The fastest path is removing friction you control.

Common failure points you can control

• Inconsistent or hard-to-find clinical criteria.
• Manual intake, rekeying, and back-and-forth for basic data.
• Missing clinical context at submission (labs, notes, imaging).
• Fragmented imaging workflows and site-of-care confusion.
• Opaque benefit accumulators that surprise members with costs.
• High variation in decisions across reviewers and plans.

Metrics that actually move outcomes

• Time to decision: median and 90th percentile (standard and urgent).
• Time from order to first treatment or imaging.
• Initial denial rate and appeal overturn rate.
• % requests auto-approved and % gold-carded providers.
• % submissions complete on first pass (no additional info needed).
• Peer-to-peer volume and wait time.
• Member grievances per 1,000 and complaint themes.
• Out-of-pocket variance vs estimate, by service line.

90-day playbook to cut delays

• Publish criteria in plain language and map each request to a single, visible checklist.
• Auto-approve low-variance, evidence-based indications with clear guardrails and audit trails.
• Gold-card high-accuracy providers based on historical approval rates and documentation quality.
• Set strict SLAs (e.g., 72 hours urgent, 7 days standard) and display real-time queues and aging to reviewers and providers.
• Enable electronic prior auth (ePA) and attachments (X12 278/275 or FHIR PAS/CRD/DTR) to eliminate rekeying.
• Require specific denial reasons with missing elements listed and exact next steps.
• Pre-service cost estimates shared with providers and members before scheduling.
• Dedicated imaging lane with standardized site-of-care rules and scheduler access.
• Weekly review huddles for top denials, overturns, and outliers; fix one root cause per week.

Reduce out-of-pocket surprises

• Real-time benefit checks at order entry with co-pay, deductible, and accumulator status.
• Transparent step therapy and exception pathways with estimated timelines.
• Member outreach on denials with covered alternatives and fast-track appeal options.

Compliance and policy signals

Regulators are pushing for faster decisions, transparency, and interoperability. Build your roadmap around that trend rather than reacting case by case.

• See CMS's Interoperability and Prior Authorization Final Rule: official fact sheet.
• Physician-reported harms from prior auth remain high: AMA survey.

Where automation helps (and where it doesn't)

• Good: classify requests, check completeness, and surface guideline matches at intake.
• Good: predict high-probability approvals and route to auto-approve with sampling audits.
• Good: generate member- and provider-friendly decision letters with clear citations.
• Not good: black-box decisions with no reason codes or auditability.

Quick checklist for your UM team

• Post criteria and checklists where providers order care.
• Adopt ePA with attachments; stop fax-first workflows.
• Stand up gold-carding and auto-approval rules with audits.
• Track decision time, treatment time, and overturns weekly.
• Require specific denial reasons and fast resubmission paths.
• Assign an owner for imaging throughput and site-of-care consistency.

The data shows where patients get hurt. The fixes are known, measurable, and within reach. Pick three changes, commit for 90 days, and watch delays fall.
