Most recreational divers in Vietnam do not automatically need a medical certificate before every dive. The usual starting point is a diving medical questionnaire used by organisations such as PADI, SSI and other training agencies. Your answers determine whether medical clearance is required before taking part.
If clearance is needed, the doctor is being asked a specific question: whether there is a medical reason that makes recreational scuba diving or freediving unsafe for you. This is different from a routine Vietnamese health certificate for employment or a general annual check-up.
The practical difficulty in Vietnam is that dive-specific examination prices are rarely published by hospitals. The cost therefore depends on the consultation and whether the doctor considers additional tests necessary. Confirm both the required form and the clinic's ability to complete it before booking.
Do you need a medical certificate to dive in Vietnam?
Not necessarily.
PADI requires student divers to complete the Diver Medical Participant Questionnaire. If the answers do not trigger medical review, a physician's examination is generally not required under the standard recreational screening process.
If the questionnaire identifies a relevant condition, written medical clearance is required before participating in the affected diving activities.
Vietnamese dive operators use this type of screening as well. EcoDive Vietnam publishes the standard Diver Medical Participant Questionnaire, while dive centres in destinations such as Phu Quoc and Nha Trang direct customers to medical questionnaires before training or diving.
The dive centre can also impose its own participation requirements, so ask before travelling to the dive site.
When does the questionnaire require a doctor?
The current recreational diving questionnaire covers conditions that can affect safety underwater, including areas such as:
- Lung or breathing disorders
- Heart or circulation problems
- Loss of consciousness or seizures
- Diabetes
- Significant ear or sinus problems
- Certain neurological conditions
- Recent surgery or injuries
- Some mental health conditions
- Prescription medication use
- Pregnancy
A positive response does not automatically mean that you cannot dive. It means the condition needs appropriate medical assessment before clearance can be given.
PADI specifically notes that the physician should mark the diver as Approved or Not Approved on the standard form. Conditional approval, such as imposing a depth limit, is not part of the current recreational screening form.
What does a diving medical examination involve?
There is no single fixed examination that every recreational diver receives.
The doctor normally starts with your medical history and the issue that triggered the questionnaire. The assessment may include:
- Blood pressure and pulse
- Heart and lung examination
- Ear, nose and throat assessment
- Review of medications
- Previous surgery or injury history
- Neurological history when relevant
- Exercise tolerance and general physical fitness
Additional tests depend on the medical question rather than being mandatory for every recreational diver.
For example, a doctor evaluating a respiratory condition might need pulmonary testing, while someone with a cardiovascular history may need a different assessment. A routine chest X-ray, ECG or blood panel should not be assumed to be necessary simply because you need a recreational diving certificate.
What should you bring to the appointment?
Bring the exact medical form required by your dive school or training agency.
Useful documents include:
- Passport or identification
- Diver Medical Participant Questionnaire
- Physician's Evaluation Form
- Current medication list
- Relevant medical reports
- Previous cardiology, respiratory or ENT results if applicable
- Diving certification if you are already qualified
- Details of the diving activity or course
If your dive centre has supplied its own form, use that version rather than asking a clinic for a generic medical certificate.
This distinction matters because a standard medical certificate in Vietnam may not contain the wording required by the dive operator.
How much does a diving medical certificate cost in Vietnam?
There is no reliable national price for a recreational diving medical certificate in Vietnam, and major hospitals generally do not publish a dedicated fee under that exact service name.
For a straightforward case requiring only a medical consultation and form completion, the starting cost may be similar to an outpatient consultation. Published 2026 Vinmec prices provide some useful context:
| Published service | Example fee |
|---|---|
| General medicine consultation at Vinmec Nha Trang | 345,000 VND with appointment |
| General medicine consultation without appointment at Vinmec Nha Trang | 550,000 VND |
| General medicine consultation at Vinmec Da Nang | Around 690,000 VND |
| Longer or specialist consultation | Can exceed 1 million VND |
These are general consultation prices, not advertised diving-medical packages. They show the possible starting cost of seeing a doctor, but they do not prove that the specific hospital or doctor will issue your required diving clearance.
If tests are required, the final cost can rise substantially.
What can make the examination more expensive?
The main variable is whether the doctor needs additional investigations before deciding that you are fit to dive.
| Possible additional service | When it might be considered |
|---|---|
| ENT examination | Ear pressure equalisation, sinus or previous ear problems |
| Spirometry | Relevant respiratory history |
| ECG | Selected cardiovascular concerns |
| Cardiology review | Known or suspected heart disease |
| Blood tests | When relevant to the medical condition being assessed |
| Imaging | Only when clinically indicated |
| Specialist consultation | When the examining doctor cannot safely clear the condition alone |
Ask the clinic whether tests are likely to be required before assuming that the consultation fee is the total cost.
Where can you get a diving medical certificate in Vietnam?
A licensed physician can perform the medical assessment, but for complicated conditions it is preferable to use a doctor familiar with diving medicine.
Divers Alert Network, or DAN, operates a worldwide physician referral network specifically for people who need fitness-to-dive evaluations or advice about diving with medical conditions. DAN can provide contact information for appropriately trained physicians based on location and clinical needs.
This can be particularly useful if you have:
- Asthma or another lung disorder
- Heart disease
- Previous spontaneous pneumothorax
- Seizures or neurological disease
- Previous decompression illness
- Significant ENT problems
- A complicated medication history
For a simple questionnaire-triggered review, a general physician may be able to complete the assessment, depending on the condition and the requirements of the diving organisation.
Getting clearance in Nha Trang
Nha Trang is one of Vietnam's main diving destinations, so arranging medical care there is generally easier than on a small island.
Local dive businesses use medical screening forms, and Vinmec Nha Trang International Hospital provides general and specialist consultations. However, a hospital's availability of general medical care does not automatically mean that every doctor will sign a diving fitness form.
Before booking, contact the hospital or clinic and say clearly:
"I need a physician to complete a recreational scuba diving medical clearance form."
Send the form in advance if possible.
Getting clearance in Phu Quoc
Phu Quoc also has a substantial recreational diving industry. Rumblefish Diving Center, for example, states that participants must be medically fit for diving and provides access to the relevant medical form.
If your questionnaire indicates that physician clearance is necessary, arrange the examination before the first in-water session.
Do not assume that the dive centre itself can issue the certificate. Dive instructors can screen the paperwork but are not acting as physicians when determining medical fitness.
What about Con Dao?
Planning ahead is particularly important in destinations with fewer medical services.
Con Dao Dive Center explicitly tells freediving students who answer yes on the medical questionnaire to consult a doctor before travelling and bring signed medical clearance, stating that it cannot provide doctor certification on the island.
This is a useful example of why the medical form should be completed before travelling to a remote dive destination.
If you already know that an answer will require medical review, obtaining clearance in Ho Chi Minh City, Hanoi or another larger city may be easier.
Can a normal hospital doctor sign the PADI medical form?
PADI's standard physician evaluation form asks for a physician's assessment of whether the participant is medically suitable for recreational scuba diving or freediving.
For uncomplicated cases, a licensed doctor may be able to make that assessment.
For unusual or significant medical conditions, DAN recommends consultation with a physician knowledgeable in diving medicine. Its referral network requires participating physicians to have specific diving or hyperbaric medical training.
The Undersea and Hyperbaric Medical Society also notes that acceptance of diving clearance varies internationally and that physician-signed clearance is the safest format for international use.
How long is a diving medical certificate valid?
Validity depends on the training agency, dive operator and purpose of the certificate.
PADI standards have traditionally treated medical clearance used for training as valid for one year, subject to changes in health. A new illness, injury or relevant medical change can require a new questionnaire and potentially new physician clearance before returning to the water.
Do not rely on an old certificate if your health has changed.
DAN also recommends ongoing medical screening throughout a diver's life rather than treating one clearance as permanent.
Recreational and commercial diving certificates are different
This guide concerns recreational scuba diving and freediving.
Commercial, occupational, military and professional diving can involve much more extensive medical standards. These examinations may include formal pulmonary testing, audiometry, ECG, exercise assessment and other investigations according to the applicable occupational system.
A PADI recreational clearance should therefore not be assumed to satisfy an employer requesting an occupational diving medical.
Ask exactly which standard the organisation requires before paying for an examination.
Does every diver over a certain age need a certificate?
The modern recreational screening system does not simply require every healthy adult over a fixed middle-age threshold to obtain physician clearance.
DAN's lifelong fitness guidance uses age, chronic illness and cardiovascular risk factors to determine when more formal assessment becomes appropriate. Its current framework recommends more frequent medical evaluation for older divers and people with relevant health conditions or risk factors.
A dive centre may nevertheless apply stricter policies, so confirm its requirements before booking.
What if you have asthma?
A history of asthma does not automatically answer whether an individual can safely dive.
Diving exposes the respiratory system to pressure changes and increased breathing resistance, so respiratory conditions require careful assessment. The relevant questions include symptom control, triggers, lung function and individual history.
Do not hide asthma or another respiratory diagnosis to avoid the medical review. If your questionnaire requires evaluation, see a physician and provide accurate information.
What if you have ear or sinus problems?
Pressure equalisation is fundamental to diving.
Active congestion, some ear disorders and certain sinus problems can interfere with equalisation and increase the risk of barotrauma. A doctor may recommend an ENT assessment when there is a significant history.
Do not dive with an acute cold or significant congestion simply because you already hold a medical certificate. Fitness to dive can change from one day to the next.
What if you take prescription medication?
The standard questionnaire asks about prescription medicines because both the underlying condition and the medication itself may matter underwater.
Bring the exact medication names and doses to the appointment.
Do not stop prescribed medication purely to obtain an easier answer on a diving questionnaire. The appropriate question is whether the condition and treatment are compatible with safe diving.
Booking a diving medical in Vietnam
The easiest process is usually:
- Complete the medical questionnaire before booking the dive course.
- Ask the dive centre whether physician clearance is required from your answers.
- Obtain the exact form they accept.
- Contact a hospital or clinic before attending.
- Send the form and explain that it is for recreational scuba or freediving clearance.
- Ask whether the doctor is comfortable performing fitness-to-dive assessments.
- Ask for the consultation fee and likely additional testing costs.
- Bring relevant medical records to the appointment.
- Keep the original signed form and a digital copy.
If you need general guidance on using Vietnamese hospitals, How hospitals work in Vietnam explains the differences between public, private and international facilities.
Can you get the certificate on the same day?
Possibly, when the medical history is straightforward and the doctor does not need additional testing or specialist review.
However, do not rely on same-day clearance immediately before a prepaid dive course. A positive finding may require testing or another appointment before the physician can make a decision.
Booking several days before diving is safer, and arranging the assessment before travelling to an island or remote location is even better.
Is the medical certificate covered by insurance?
Often not when the examination is being performed solely for participation in a recreational activity.
International health insurance and travel insurance policies vary. Some may cover a consultation if there is a genuine medical reason for evaluation, while an administrative fitness certificate may be excluded.
Ask the insurer before the appointment if reimbursement matters to you.
What happens if the doctor does not clear you?
A doctor declining to sign the form does not necessarily mean that you can never dive.
The clinician may need more information, additional testing or specialist input before making a decision. For complicated cases, a diving medicine physician can provide a more specialised assessment.
Do not shop around for another signature while withholding the condition that caused the first doctor concern.
When should you not dive even with a certificate?
A medical clearance reflects an assessment at a particular point in time. It does not guarantee that you are fit to dive on every future day.
Do not dive when acutely unwell. Fever, significant respiratory symptoms, vomiting, severe diarrhoea, marked dehydration or an inability to equalise ear pressure can make diving unsafe even if you previously passed a medical examination.
After an injury, significant illness or suspected diving-related problem, seek appropriate medical evaluation before returning to the water.
For urgent illness while travelling, use an appropriate clinic or hospital rather than waiting for a diving certificate appointment.
What to remember
You do not automatically need a physician's certificate for recreational diving in Vietnam. Start with the medical questionnaire used by your dive centre or training agency. If your answers require medical clearance, obtain the exact physician form before booking an examination.
Vietnam does not have a single published national price for dive medicals. A straightforward examination may begin with the cost of an ordinary medical consultation, while respiratory, cardiac, ENT or other investigations can increase the total substantially.
Contact the clinic before attending, explain that you need recreational diving clearance and send the form in advance. If you have a significant medical condition or the doctor is uncertain about diving-specific risk, DAN can help locate a physician with diving medicine experience.
Frequently Asked Questions
Do I need a medical certificate to scuba dive in Vietnam?
Not every recreational diver needs one. You normally complete a diving medical questionnaire first, and certain answers require evaluation and written clearance from a physician before diving.
How much does a diving medical certificate cost in Vietnam?
There is no standard published national fee for a recreational dive medical. A straightforward assessment may start with a normal consultation fee, while additional ENT, lung, heart or other testing can increase the total cost considerably.
Can any doctor sign a PADI medical form in Vietnam?
A physician may be able to complete a straightforward recreational diving assessment, subject to local professional rules and the dive organisation's requirements. For complicated conditions, a physician with diving or hyperbaric medicine experience is preferable.
What tests are included in a diving medical?
There is no mandatory battery of tests for every recreational diver. The doctor usually reviews your history and performs a clinical examination, then orders tests such as spirometry, ECG or specialist assessment only when medically relevant.
Can I get a diving medical certificate in Nha Trang or Phu Quoc?
Both destinations have hospitals and clinics as well as active diving industries, but you should confirm in advance that a specific doctor will complete the required diving form. Some remote destinations have more limited options, so obtaining clearance before travelling can be easier.
How long is a diving medical certificate valid?
Validity depends on the training agency and dive operator. PADI medical clearance used for training is generally treated as valid for one year, but a new illness, injury or relevant change in health can require a new assessment sooner.
