When you’re experiencing discomfort, unusual symptoms, or preparing for pregnancy monitoring, an ultrasound may be one of the first imaging tests your healthcare provider recommends. We have often been asked the same question while serving our population in Ontario – “do I need a referral to get an ultrasound?”
The short answer is: Yes, in most cases you do need a referral.
Let’s explore the details to help you understand the process and your options.
What is an ultrasound?
Ultrasound imaging is a safe, non-invasive diagnostic tool that uses high-frequency sound waves to create real-time images of structures inside your body. Unlike X-rays or CT scans, ultrasounds don’t use radiation, making them particularly suitable for pregnancy monitoring and repeated examinations.
Common uses for ultrasound include:
- Diagnosing abdominal pain and digestive issues
- Pelvic examinations for uterine, ovarian, or prostate concerns
- Pregnancy monitoring and fetal development tracking
- Thyroid gland assessments
- Musculoskeletal conditions affecting joints, tendons, and ligaments
- Kidney and bladder evaluations
- Vascular assessments to check blood flow
Referral requirements in Ontario
In Ontario, most diagnostic ultrasound examinations require a requisition (medical referral) from a licensed healthcare provider. This requirement exists because OHIP (Ontario Health Insurance Plan) only covers ultrasounds when they are deemed medically necessary by a qualified healthcare professional.
Who can provide a referral?
The following healthcare providers can issue ultrasound requisitions:
- Family physicians (general practitioners)
- Nurse practitioner
- Medical specialists (such as obstetrician/gynecologist, urologists, or cardiologists)
- Emergency department physicians
- Walk-in clinic doctors
Ultrasounds that require a referral:
Most diagnostic ultrasounds require a referral, including:
- Abdominal and pelvic ultrasounds
- Thyroid examinations
- Musculoskeletal (MSK) ultrasounds
- Renal (kidney) and bladder scans
- Prostate and scrotal examinations
- Vascular studies
- Most breast ultrasounds
Which ultrasounds do not require a referral?
Very few ultrasounds in Ontario can be obtained without a referral under OHIP coverage.
The main exception is certain breast cancer screening ultrasounds through the Ontario Breast Screening Program (OBSP). Refer to https://www.gamdi.ca/services/obsp/ to see the eligibility requirements for high-risk patients.
Private ultrasound options (not covered by OHIP) may be available without referrals, such as:
- Elective 3D/4D pregnancy keepsake scans
- Cosmetic or wellness screening packages
- Some private health assessments
Note: These private services require out-of-pocket payment and are not considered medically necessary.
OHIP coverage and what to expect
Good news: If you have a valid OHIP card and a proper medical referral, your ultrasound examination is fully covered at no cost to you.
What you’ll need to bring:
- Your valid OHIP card
- The original requisition form from your healthcare provider
- A list of current medications (if relevant to your examination)
- Any previous imaging results related to your condition
Preparation may include:
- Fasting for abdominal ultrasounds (typically 6-8 hours)
- Drinking water before pelvic ultrasounds to fill your bladder
- Wearing comfortable, loose-fitting clothing
- Removing jewelry from the examination area
Don’t have a family doctor?
If you do not have a family physician, the following options are available to obtain a referral
- Walk-in clinics: Visit a walk-in clinic where a physician can assess your symptoms and provide an appropriate referral if medically indicated.
- Nurse practitioner clinics: Many community health centers have nurse practitioners who can issue ultrasound requisitions.
- Urgent care centers: For more immediate concerns, urgent care facilities can provide referrals when appropriate.
- Emergency departments: While not ideal for routine imaging, emergency departments can order ultrasounds for urgent medical situations.
