Start here
The honest answer is a range
A routine prior authorization may take several business days. Some clear quickly when everything arrives electronically and the facts plainly match the insurer’s criteria. Others run a week or more because information is missing or a clinician has to review it.
An expedited request can be decided within hours or a few days. Faster review is reserved for cases where waiting could seriously affect your health or your ability to recover function. Calling something urgent does not make it expedited — the insurer applies its own standard, on information from your treating provider.
There is no single national timeline. The deadline depends on your insurer, plan type, state law, whether it is a medication or a procedure, and whether the case qualifies as urgent. Employer plans, marketplace plans, Medicare and Medicaid can all differ.
Your plan documents are the authority. Look for the claims procedure or utilization management section. Where a timeline here conflicts with them, the plan documents win.
Know the roles
Your provider submits it, not you
Prior authorization is the insurer’s advance review of a service or medication against its coverage rules. Approval is not payment. You may still owe a deductible, copay or coinsurance, the provider generally has to be in-network for in-network benefits, and the final claim has to match what was authorised.
The submission comes from the provider’s office — diagnosis, treatment plan, results, prior treatment history. You can call, track and sometimes begin an appeal, but you cannot replace clinical documentation with your own explanation.
The prescriber often is not the person doing the paperwork. Many offices route this to a nurse, referral coordinator, pharmacy technician or a central authorization team, which is why “my doctor said they sent it” may not tell you who sent what, or when. Ask the office:
- Who handles prior authorization requests, and on what date was this one submitted?
- How was it sent, and did the insurer confirm receipt?
- Has the insurer asked for anything else?
- What reference or case number is attached to it?
Find the start
A complete request is what starts the review
The date the order was written is rarely the date review began. A prescription written Monday may reach an authorization employee Tuesday and the insurer Wednesday — and if records are missing on Thursday, it may not reach a reviewer until they arrive.
Incomplete submissions are the most avoidable cause of delay. A request stalls for want of office notes, imaging, lab results, treatment dates, diagnosis codes, dosage, or evidence that another treatment was tried first. A specialty drug can be on the formulary and still need all of that.
Consider an illustrative sequence: ordered Monday, request created Tuesday, received Wednesday without the latest notes, insurer asks for them Thursday, office sends them the following Monday, file recorded complete on Tuesday. Eight days from your side; one day of complete file from the reviewer’s.
So do not stop at “did you get it?” when you call. Receipt and completeness are different questions. Ask whether the file is complete, whether it is with a clinical reviewer, and whether anything is outstanding from the provider.
Use the faster lane
Expedited review needs documented urgency
Ask about expedited handling when the standard wait could create a serious health risk. Contact both sides: ask the provider whether the situation meets the plan’s urgent-review standard and whether the office can submit clinical support for it. Plain wording works:
The standard review time may be too long here. Can the treating provider request expedited review and document the clinical urgency?
A scheduling preference, an upcoming trip, or frustration with the process will not usually satisfy the plan’s definition. Do not assume an expedited request was accepted — ask the insurer whether it is classified standard or expedited, and record the answer, date, representative and case number.
Ask the prescriber what to do while you wait: a temporary option, a sample, or a covered alternative may be available. Do not start, stop or substitute medication on the basis of an insurance conversation. If a delay looks immediately dangerous, contact the clinician or emergency services rather than waiting for a callback.
When coverage says no
A denial is not the end of it
The insurer has to explain why. Read the reason before resubmitting — sending the same material again usually produces the same answer. Common categories:
- required clinical records were not submitted
- the request did not meet the insurer’s stated criteria
- the medication is not on the formulary, or a preferred option must be tried first
- the service is excluded under the plan
- the provider, facility or site of care does not meet the plan’s rules
A corrected request and an appeal are not the same thing. If a note or result was missing, the office may be able to send it or resubmit. If a complete file was reviewed and refused, the next step is usually an internal appeal, and some denials can then go to external review by an independent reviewer.
The Department of Labor sets out the general framework in Filing a Claim for Your Health Benefits. Your denial notice and plan documents remain the sources that actually govern your case.
Keep copies of everything, and keep a call log: date, representative, reference number, status, what is missing, and the promised next action. When the insurer and the office disagree, that log is what shows you where the request stopped.
The hidden step
Step therapy adds a delay people do not expect
Step therapy requires you to try the plan’s preferred treatment first. A drug can need both prior authorization and proof the step was completed — and a request often starts as a routine authorization, only to be sent back once the insurer notices the step requirement was never addressed.
Suppose your prescriber requests Drug B while the formulary requires Drug A first. The insurer may refuse unless the records show you tried Drug A for the required period and it failed, that it caused a documented problem, or that your provider can explain why it is inappropriate under the plan’s exception rules. That is an illustrative example; the real requirements come from your formulary and plan documents.
If you tried the required drug under a previous insurer, say so. Ask whether those records can be submitted — do not assume the current insurer can see them.
