How to Plan Your Scuba Diving Medical Clearance Before a Dive Trip

Most new divers meet the medical form the same way. A dive shop sends the course paperwork a week or two before training starts, and one page asks a long list of yes or no health questions. For many people every answer is no and the form takes minutes. For anyone who answers yes, training cannot begin until a physician reviews their history and signs off, and that step is where dive trips get delayed.

Understanding what the scuba diving medical involves, when a physician’s signature is required, and how much time to allow can keep the medical step from becoming the reason a course date or a dive vacation slips.

What the Scuba Diving Medical Actually Is

The Diver Medical Participant Questionnaire

The standard screening form used by PADI, SSI, NAUI and most other recreational training agencies is the Diver Medical Participant Questionnaire. It was developed by the Diver Medical Screen Committee in association with the Undersea and Hyperbaric Medical Society, Divers Alert Network, DAN Europe and the hyperbaric medicine division at the University of California, San Diego, and the current system was released in 2020.

The questionnaire focuses on the conditions that matter most underwater. It asks about lung and breathing problems, heart conditions, ear and sinus issues that affect equalization, seizures and other neurological history, diabetes, behavioral health, recent surgery and prescription medications.

The Physician’s Evaluation Form

When a physician’s opinion is needed, it is recorded on a separate page called the Diver Medical Physician’s Evaluation Form. It does not have to be completed in an office, and an online scuba medical clearance can be done through a records review and a live video visit with a licensed physician. Either way, the result is binary. The physician either finds no conditions they consider incompatible with recreational scuba diving or freediving and approves the diver, or does not. There is no conditional approval, which is one reason some physicians are cautious about signing it.

When a Physician Signature Is Required

Yes Answers on the Questionnaire

A diver who answers no to every question can usually self-certify and begin training. A yes answer works differently. Most yes answers lead to follow-up questions on the form, and depending on those answers, a physician must evaluate the diver and sign before any in-water training.

A yes does not mean a person cannot dive. Many common histories, including mild, well-controlled asthma and blood pressure managed with medication, are often compatible with recreational diving once a physician has reviewed them.

Operators That Ask Every Diver

Some dive operators, liveaboard boats and training centers ask every diver for a physician-signed medical regardless of how the questionnaire was answered. Professional-level courses may require one as well. Reading the exact requirements a shop or boat sends, before assuming the questionnaire alone will be enough, avoids a surprise on the first day.

How Far Ahead to Plan

Gathering the Right Records

The physician will want documentation that relates to each yes answer. That usually means recent clinic notes, a current medication list and condition-specific results, such as spirometry for asthma or a cardiology summary for a heart history. Requesting records from a primary care office can take several days, so it is worth starting as soon as the course is booked.

Allowing for Additional Testing

Some histories need more than a records review. Published diving medical guidance advises against diving for people whose asthma is triggered by exercise, cold air or emotion, and treats an exercise test as the best way to assess fitness in less clear cases. A history of spontaneous collapsed lung is, in most cases, considered incompatible with diving. When further testing or an in-person examination is needed, it can add days or weeks, so divers with a complex history benefit most from planning a month or more ahead.

Where to Get the Form Signed

Your Own Doctor

A primary care physician can sign the form, but many see it rarely, and some decline because diving physiology falls outside their usual practice or because the signature carries their license. Asking early leaves time to find an alternative if the answer is no.

A Dive Medicine Physician

Physicians with training in diving and hyperbaric medicine are the right choice for complex cases and for anyone who needs in-person testing. Divers Alert Network maintains a referral service that can help divers locate one.

An Online Evaluation

For straightforward histories, an online evaluation is another option. A physician reviews the diver’s records before a scheduled live video visit and signs the evaluation form when clearance is appropriate. A legitimate service is led by a named, licensed physician, holds a license in the state where the diver is located during the visit, reviews records rather than relying on the questionnaire alone, and refers divers to in-person care when their history requires it.

A Practical Checklist Before Your Dive Trip

• Ask the dive shop or boat for its medical requirements as soon as you book
• Complete the questionnaire honestly and note every yes answer
• Request the records related to each yes answer from your doctor’s office
• Book the physician evaluation with time to spare before training begins
• Allow extra time if your history may need testing or an in-person exam
• Keep a copy of the signed form with your certification card, since many operators ask to see it again

Keep the Medical Step Ahead of the Trip

Some dive operators and training programs require a physician clearance dated within the previous 12 months, while others may follow different requirements. Check with the specific dive shop, course provider or liveaboard before traveling, especially if you have a medical history that requires evaluation. Treating the medical as part of trip planning, rather than a last-minute form, can help prevent delays to the course or trip.

Honesty matters as much as timing. The questionnaire exists to catch conditions that can become dangerous at depth, and an honest yes followed by a proper evaluation is how most divers with a medical history get safely into the water.
