Health insurance pre-approval: What patients need to know
Health insurance pre-approval (also called prior authorization) can feel like a maze for patients and providers. Follow Sarah, a mother navigating a complex approval for her child’s specialist visit, to learn practical steps you can use today.
For clear strategies and basic checklists, see our health insurance tips page to get started. Understanding the process helps you avoid delays and unexpected bills.
Insurers like UnitedHealthcare, Cigna, Aetna and Blue Cross Blue Shield all use prior authorization to verify medical necessity before approving drugs, MRIs, or surgeries. Processes differ by company and plan type, which is why knowing insurer-specific rules matters.
Sarah learned her child’s plan through Kaiser Permanente required one form, while a family friend on Humana needed a phone approval plus clinical notes. That contrast shows how variable procedures can be.
- Contact: Provider initiates request to insurer with clinical justification.
- Review: Insurer reviews against policy criteria and clinical guidelines.
- Decision: Approval, denial, or request for more information.
- Appeal: If denied, follow insurer appeal pathways quickly.
Knowing each insurer’s workflow — including Anthem, Molina Healthcare, Centene Corporation, and Oscar Health — reduces surprises at the time of care. This knowledge can save time and out-of-pocket costs.
Denials often come down to missing documentation, treatment considered experimental, or care outside plan guidelines. Sarah’s denial stemmed from an omitted lab result that her pediatrician had not attached. Small missing items cause big delays.
To learn how to respond when a denial happens, review our detailed advice on handling denials and appeals for practical steps and templates.
- Incomplete clinical records — labs, notes, or imaging missing.
- Treatment not listed as covered or deemed experimental.
- Incorrect billing codes or mismatched provider information.
- Timeliness — requests submitted after plan deadlines.
For actionable tactics to overturn denials, consult our denials tips and appeal guides that walk you through evidence collection and escalation steps.
How to speed up pre-approval: practical steps you can take
Speed wins when time-sensitive care is needed. Sarah’s pediatrician started the prior authorization the same day the specialist recommended care, which cut waiting time in half. Quick action and accurate documentation are the most effective levers.
Use these steps as a checklist before submission to minimize back-and-forth with the insurer.
- Prepare complete clinical documentation: labs, notes, and justification.
- Verify correct CPT/ICD codes with your provider before submission.
- Ask the insurer for their required forms and preferred submission channel.
- Document all calls and get reference numbers for follow-up.

Quick resources and forms to keep handy
Having the right forms and a small packet of records can make or break the approval timeline. Sarah keeps a folder with her child’s recent labs and a printed authorization checklist that travels between clinic visits. This practice cuts administrative friction significantly.
Key documents to maintain are available through plan portals or employer HR teams, and filing them smartly saves time when care is urgent.
- Completed prior-authorization forms from the plan portal.
- Copies of recent labs, imaging, and specialist notes.
- Billing/coding references and previous approval letters if applicable.
- Form 1095-C or employer insurance verification when needed for claims.
For forms and consumer-facing checklists, see our resources on Form 1095-C and practical insurance tips.
Turnaround varies: many insurers respond within 3–7 business days for routine requests and faster for urgent cases. Document completeness and correct coding speed up decisions. Always ask your provider for expected timelines and get a reference number for follow-up.
First, request the insurer’s written denial reason. Then gather supporting clinical records, ask your provider to submit an appeal with a detailed letter of medical necessity, and follow the insurer’s escalation steps. Our guides on denials and appeals explain step-by-step actions.
Yes. Plan design and network choices influence how often prior authorization is required. High-deductible plans or certain networks may have different lists of services needing approval. Use our plan-selection guidance during open enrollment to minimize future hurdles.
