How long does a second opinion take?

Two routes, two different clocks

There are two ways to get a second opinion in Australia, and what governs the timing is completely different in each. The in-person route runs on appointment availability. The written document review route runs on how fast the paperwork can be assembled and read. Comparing the two timelines directly is a bit misleading — one includes a specialist examining you, the other never does. Both routes are set out in how to get a second opinion.

The in-person route: the wait is the appointment

There are usually two waits, stacked.

The first is getting in to see your GP. A referral is generally required to claim a Medicare rebate on a specialist attendance — Services Australia sets out how referrals and rebates work, and there's more in do I need a referral.

The second is the specialist's own waiting list, and nobody can honestly quote you a number for it. It varies by specialty, by whether you're going public or private, and by where you live — a wait for private rooms in a capital city and a wait for a regional public outpatient clinic are not comparable figures. Ring the rooms and ask two things: the next available appointment, and whether they keep a cancellation list. Then add the time it takes for your records to reach them, which is a separate step people routinely forget.

The document review route: the clock starts at acceptance

Otro's stated turnarounds are:

Both are measured from the date a specialist accepts your case — not from the date you submit it. Business days means weekdays, so a case accepted on a Thursday has a weekend inside its window.

These are estimates, not guarantees — what the process normally takes, not a commitment we can make on behalf of a specialist reading a complex file.

Why "from acceptance" is not a technicality

Between submission and acceptance sits triage. A specialist has to look at what you've sent and decide whether they can usefully review it. They may decline — because it sits outside their subspecialty, because there's a conflict, or because the documentation doesn't support a meaningful review. If that happens we look for another suitable specialist, and if we can't find one, you aren't charged at all. Your card is authorised when you submit and only charged when a specialist accepts.

So elapsed time from the day you press submit can be longer than the window above, sometimes considerably. A turnaround quoted from submission would include a step nobody fully controls. We'd rather measure the part we do control and be plain about the part we don't.

What actually causes delay

• Missing documents. A common cause. If something central is absent you'll get a request for more information, and the clock effectively stops until it arrives.
• Records held by someone else. Hospital medical records units, practices you've left, specialists you saw years ago — each has its own process and turnaround. You can generally request access to your own health information; the Office of the Australian Information Commissioner explains how privacy rules apply to health records, and public hospitals run their own state-based process. Start early — this step can add weeks.
• Imaging. A radiology report and the actual images are two different things. If the question turns on what a study shows, the reviewing specialist may need the study itself — usually a copy requested from the practice that performed it. See imaging second opinions.
• Unclear questions. Vague questions produce a round of clarification before anything else happens. Questions to ask covers how to write them.
• Public holidays. Business days are business days.

What you can do to shorten it

• Assemble everything before you submit, not after — what documents you need is the checklist.
• Ring the hospital's medical records unit the day you start thinking about this, not the day you submit.
• When you ask a radiology practice for a report, ask for a copy of the images at the same time.
• Write your questions down first, in plain language, and keep them specific.
• Watch your email. An unanswered request for more information will hold a case up indefinitely.

When the timeframe makes this the wrong move

Sometimes the honest answer is that a second opinion won't arrive in time to be any use, and it's better to know that before you start than after.

• When a decision is imminent. If surgery is booked for next week or treatment starts on Monday, days to weeks may simply not fit. Ask your treating team whether the date can move and what a delay would mean in your case — that's a question for them, not for us. Before surgery covers that conversation.
• When you're acutely unwell or something is changing quickly. A written review is not the right tool. Contact your GP, use healthdirect to find the health advice line for your state, or in an emergency call 000.
• When the waiting itself carries a cost. Delay is not neutral. If pausing a plan to wait for a report has consequences, weigh those consequences honestly rather than treating the review as free.
• When you need to be examined or to have a conversation. No document review does either, however fast it is.
• When there's no specific decision in front of you. A second opinion isn't routinely advisable, and speed is beside the point if the review has no question to answer. If the real problem is the relationship rather than the opinion, second opinion or change doctors is the more useful read.

Where Otro fits

Otro is a technology platform, not a healthcare provider — we don't form clinical opinions. An independent, AHPRA-registered Australian specialist reviews your documents and writes a structured report across seven set sections; you can check any practitioner's registration on the public register of practitioners maintained by AHPRA. Our Chief Medical Officer checks every report for structure, clarity and completeness before release — never the clinical conclusion, which stays with the reviewing specialist.

No referral is needed, the service is for people in Australia aged 18 and over, and it isn't claimable under Medicare or covered by private health insurance. Whether an in-person specialist attendance attracts a rebate depends on the item and your circumstances — ask your GP or Services Australia.

It's the wrong fit if your timeline is shorter than the process, if you need an examination, or if you don't yet have documents to review. See how the service works and pricing, or contact us to check the timing before you start.
