Medical referral letter examples, a referral letter template, and step-by-step guidance on how to write a doctor, patient, or specialist referral letter.
A medical referral letter helps transfer a patient from one healthcare professional to another for additional assessment, treatment, or specialist advice.
A strong referral letter explains why the referral is being made, what has already been assessed or treated, and what the receiving clinician is being asked to do.
This guide explains what a referral letter should include, how to write one, common mistakes to avoid, and includes a reusable template and complete examples.
A medical referral letter is a clinical document sent by one healthcare professional to another when a patient requires additional evaluation, treatment, or specialist input. The letter gives the receiving clinician enough relevant information to understand the patient’s condition and determine the appropriate next step.
A referral letter is not simply a copy of the patient’s medical record. It should be a focused clinical request that communicates:
Vague example: Please assess this patient for knee pain.
More useful example: Please assess this patient’s persistent medial knee pain and intermittent locking, which have not improved after six weeks of physiotherapy and activity modification. I would appreciate your opinion on possible meniscal pathology and whether further imaging or surgical consultation is indicated.
The exact information depends on the patient, receiving service, and specialty. However, most referral letters should include the following elements.
Confirm that this information is accurate before sending the referral.
The receiving clinician should be able to contact the referrer easily if clarification is needed.
State the main reason for referral near the beginning of the letter. This should identify the presenting problem, the purpose of the referral, the specific clinical question, and the requested action.
Avoid copying the entire patient chart into the letter.
Include normal findings only when they help rule out serious conditions, narrow the differential diagnosis, or support referral triage.
Whenever possible, include the date and the meaningful result rather than writing only “normal bloodwork” or “imaging completed.”
Explain what has already been tried, including medications, physiotherapy, activity modification, counseling, home exercise, injections, monitoring, or other conservative treatments. Include the duration and the patient’s response.
Example: The patient completed eight physiotherapy sessions over six weeks. Stair tolerance improved slightly, but locking episodes and inability to run persisted.
Include medications that affect the presenting problem, specialist decision-making, or procedural safety. Also include known medication allergies and relevant adverse reactions.
State whether the referral is routine, expedited, or urgent. When requesting urgent assessment, explain the clinical facts supporting the urgency.
Example: Expedited assessment is requested because the patient has developed progressive right-leg weakness over the past two weeks, with new foot drop identified on examination today.
This is more useful than writing only “please see urgently.”
Date: July 20, 2026 To: Orthopedic Surgery Clinic Re: Daniel Carter Date of birth: March 14, 1982 Dear Orthopedic Colleague, Thank you for assessing Daniel Carter, a 44-year-old patient with persistent right knee pain and intermittent locking following a recreational soccer injury approximately three months ago. Daniel reports twisting his right knee while changing direction during a game. He developed medial knee pain and mild swelling later that day. The swelling improved over the following week, but he continues to experience pain with squatting, stairs, and pivoting. He also reports four episodes of locking and occasional instability. On examination, there is medial joint-line tenderness and mild limitation of flexion due to pain. McMurray testing reproduces medial knee pain. Ligament testing is stable. There is no significant effusion, erythema, or neurovascular deficit. A right knee X-ray completed on June 28, 2026 showed no acute bony abnormality or significant osteoarthritis. Daniel has completed six weeks of activity modification, topical anti-inflammatory treatment, and supervised physiotherapy. His baseline pain has improved, but the mechanical symptoms and inability to return to running have persisted. His relevant medical history includes hypertension controlled with amlodipine. He has no known drug allergies. Please assess for possible medial meniscal injury and advise whether MRI, injection therapy, or surgical management should be considered. Sincerely, Dr. Maya Patel Family Physician Riverside Family Health Centre Telephone: 555-0142 Fax: 555-0188

A template should act as a completeness check. It should not encourage clinicians to fill every section with unrelated chart information.

Date: July 20, 2026 To: Cardiology Clinic Re: Amanda Lewis Date of birth: September 9, 1975 Dear Cardiology Colleague, Please assess Amanda Lewis, a 50-year-old patient with six weeks of intermittent exertional chest pressure and reduced exercise tolerance. The discomfort occurs when walking uphill or climbing more than two flights of stairs and resolves within approximately five minutes of rest. She has not experienced syncope, resting chest pain, orthopnea, or lower-extremity edema. Her cardiovascular risk factors include hypertension, hyperlipidemia, and a 15-pack-year smoking history. Her father experienced a myocardial infarction at age 54. Blood pressure today was 148/88 mmHg. Heart sounds were normal, with no audible murmur. Lungs were clear, and there was no peripheral edema. A resting ECG completed on July 15, 2026 showed normal sinus rhythm without acute ischemic changes. CBC and TSH were within reference ranges. LDL cholesterol was 4.1 mmol/L. Current medications include ramipril 10 mg daily and atorvastatin 20 mg daily. She has no known drug allergies. Given the reproducible exertional symptoms and cardiovascular risk factors, expedited assessment is requested. Please advise regarding further cardiac testing and management. Sincerely, Dr. Jonathan Lee Primary Care Physician Northview Medical Clinic Telephone: 555-0163 Fax: 555-0171
Date: July 20, 2026 To: Orthopedic Sports Medicine Re: Sofia Nguyen Date of birth: December 4, 2003 Dear Orthopedic Sports Medicine Colleague, Please assess Sofia Nguyen, a 22-year-old competitive volleyball player with persistent right shoulder pain and weakness following a gradual increase in overhead training volume. Symptoms began approximately four months ago and have progressed despite reduced training. Pain is most pronounced during serving, spiking, and resisted external rotation. She also reports fatigue and reduced ball velocity but no instability, neck pain, or upper-extremity numbness. Examination demonstrates painful active abduction above 100 degrees, weakness with resisted external rotation, and positive Hawkins-Kennedy and empty-can testing. Passive range of motion is preserved. Cervical screening and upper-limb neurological examination are unremarkable. Ultrasound completed on June 30, 2026 identified supraspinatus tendinopathy without a full-thickness tear. Sofia has completed eight weeks of progressive rotator-cuff and scapular rehabilitation, workload modification, and a graduated return-to-serving program. Daily symptoms have improved, but sport-specific pain and weakness persist. Please assess the persistent functional limitation and advise whether additional imaging, injection therapy, or another intervention should be considered. Sincerely, Dr. Elena Morris Sports Medicine Physician Performance Health Clinic Telephone: 555-0128 Fax: 555-0194
A routine referral is appropriate when the patient is clinically stable and the condition can be assessed through standard processes. An expedited or urgent referral may be appropriate when there is a higher risk of deterioration or time-sensitive need.
Urgency requirements vary by specialty and jurisdiction. Follow referral criteria and use emergency pathways when immediate assessment is required. A referral letter should never be used as a substitute for emergency care.
Long enough to communicate the clinical question and relevant context, but short enough to scan quickly. Many routine referrals can be completed in one page; complex cases may require attachments.
Referral authority depends on profession, service, payer, and jurisdiction. Physicians commonly write specialist referrals, but nurse practitioners, dentists, physiotherapists, psychologists, and other regulated professionals may also refer where permitted.
Yes. Use secure electronic referral systems, integrated EMRs, secure fax, or other approved methods while following privacy and organizational requirements.
Patients may be given access to referral information depending on setting and local rules. Clinicians should explain why the referral is being made, what to expect, and what to do if not contacted.
A referral letter requests assessment or treatment from the receiving clinician. A consultation note is sent back by the receiving clinician and documents their findings, recommendations, and management plan.
An urgent referral is supported by clinical findings indicating higher risk of deterioration, serious disease, permanent impairment, or a time-sensitive treatment need. The letter should state facts supporting urgency rather than relying only on the label.
