Predetermination vs. Preauthorization: What a Coverage Review Does—and Does Not—Promise
Compare predetermination with preauthorization, request a written benefits estimate and check the conditions that can change your final medical bill.

Key Takeaways
- Plan terminology and written conditions control.
- Predetermination does not replace required authorization.
- Changes before treatment can change the final benefit.
Predetermination is a plan review used to estimate how proposed care may be covered under the benefits available at the time. Preauthorization usually addresses a required medical-necessity review before specified care. Terminology varies by U.S. health plan, and neither document guarantees payment. Ask what the review covers, what remains conditional and whether a separate authorization is required.
How do the reviews differ?
Predetermination estimates how proposed treatment may fit the plan's benefits, while preauthorization generally addresses a required review before specified services. Neither guarantees payment. Ask the plan to define each review in writing, identify any separate submission requirement and explain which coverage conditions remain unresolved before relying on the response for planned care.
| Review | Purpose | What to confirm |
|---|---|---|
| Predetermination | Estimate benefits for proposed care | Whether optional, binding or conditional under this plan |
| Preauthorization | Required review for specified services | Medical criteria, approved dates and submission responsibility |
HealthCare.gov's authorization definition expressly warns that approval is not a promise of payment. A carrier may use different labels, so ask for its written definitions instead of assuming a predetermination satisfies authorization.
What information should you request?
Request a written benefits estimate that identifies the proposed services, providers, network status, expected allowed amounts and remaining cost-sharing. Ask the plan to list exclusions, limits and separate authorization requirements. The treating provider supplies accurate clinical information; the member keeps the response and checks whether changes in care require another review.
- The proposed service codes and diagnosis submitted by the clinician.
- Provider and facility network status, including separately billing specialists.
- The estimated allowed amount and your remaining deductible and coinsurance.
- Exclusions, benefit limits, expiration date and any separate authorization requirement.
Ask the provider to use the plan's submission channel, not an unrelated online form. Keep the request and response. Estimates may change if enrollment, benefits, codes, treatment or deductible accumulations change before the claim is processed.
What if coverage remains uncertain?
Resolve unanswered conditions before elective treatment where possible. Ask the plan to explain its decision in writing and identify review or appeal options. Do not treat an estimate as permission to skip required precertification. For a later dispute, compare the final explanation of benefits with the original request and clinical records.
Predetermination document and responsibility checklist
Keep the estimate and authorization as separate records unless the plan confirms in writing that its process combines them.
| Responsible party / step | Records and next action |
|---|---|
| Provider supplies | Treatment plan, accurate procedure and diagnosis codes, facility and clinician details, proposed dates and requested clinical records through the plan's channel. |
| Member requests | Current benefit documents, network confirmation, written estimate, exclusions, limits, expiration and separate authorization instructions. |
| Plan confirms | What was reviewed, conditions remaining, reference number, validity period and whether another review is required. |
| HR/broker assists | Identify the administrator and submission route with member authorization; do not interpret clinical necessity or promise the estimated payment. |
| Before care and after claim | Recheck changes in dates, services, enrollment or network; compare the eventual EOB with the estimate and request a written explanation of differences. |
Clarify agent-of-record claims and administrative support responsibilities before asking a broker to assist. Plan decisions and appeal rights remain governed by the plan and applicable rules.

Frequently Asked Questions
Does predetermination guarantee payment?
Predetermination should not be treated as a guarantee of claim payment. Ask the health plan what its written benefits estimate commits to and which eligibility, network, cost-sharing and other coverage conditions still apply.
Should I request both reviews?
Ask the health plan whether the proposed service requires both predetermination and precertification. A predetermination benefits estimate does not automatically satisfy a separate prior-authorization requirement; confirm each requirement before nonemergency care.
