Referral Letter for Therapy / Psychological Services

What Is a Referral Letter?

A referral letter for mental health services is a professional communication from one healthcare provider to another, requesting that the receiving provider evaluate, assess, or treat a patient for a specific clinical concern. Referral letters are the standard mechanism for inter-professional communication in healthcare and serve as the bridge between the referring provider's clinical observations and the receiving provider's expertise.

In mental health practice, referral letters commonly flow in several directions: from primary care physicians to psychologists or psychiatrists, from therapists to psychiatrists for medication evaluation, from one therapist to another with specialized expertise, from therapists to neuropsychologists for cognitive assessment, and from medical specialists to mental health providers when psychological factors are affecting medical care.

An effective referral letter does more than simply identify the patient and the receiving provider. It communicates the clinical context, articulates a specific referral question, provides the relevant background information the receiving provider needs to begin their work, and identifies any urgency or time-sensitive factors. A well-written referral letter saves the receiving provider time, reduces redundant assessment, and ensures continuity of care.

The quality of the referral letter often determines the quality of the response. A vague referral with no clinical context produces a generic evaluation. A specific referral with clear clinical questions, relevant history, and identified concerns produces a targeted, useful consultation.

When You Need It

• When a primary care physician suspects a mental health condition and is referring the patient for psychological evaluation or therapy
• When a therapist is referring a client to a psychiatrist for medication evaluation
• When a therapist needs to refer a client to a specialist — such as a neuropsychologist, trauma specialist, or eating disorder program
• When a client needs a higher level of care, such as intensive outpatient or inpatient treatment
• When a medical provider recognizes that psychological factors are contributing to a patient's medical presentation and wants a behavioral health consultation

Key Components

Referring provider identification. Include your name, credentials, practice name, contact information, and your role in the patient's care. The receiving provider needs to know who you are and how to reach you.

Patient identifying information. Include the patient's full name, date of birth, and contact information. If the referral is insurance-dependent, include the insurance carrier and member ID.

Referral question. State the specific reason for the referral. What clinical question do you want the receiving provider to answer? What do you want them to evaluate, assess, or treat? The more specific the question, the more useful the response.

Relevant clinical history. Provide a concise summary of the patient's relevant clinical background, including presenting symptoms, duration and onset, relevant medical history, prior treatment, current medications, and any diagnostic impressions you have formed. Include only information relevant to the referral question.

Current presentation and concerns. Describe the patient's current symptoms, functional status, and any specific concerns that prompted the referral. If there are safety concerns, state them clearly.

What you have already done. Note any assessments, screening instruments, or interventions you have already completed that are relevant to the referral question. This prevents the receiving provider from duplicating work.

Urgency and logistics. Indicate whether the referral is routine, urgent, or emergent. If there are time-sensitive factors — for example, a pending custody evaluation or a critical medication decision — note them.

How to Write It Step by Step

Step 1: Identify the right receiving provider. Consider the specific clinical question and match it to a provider with the appropriate expertise. If you are referring for ADHD assessment, a psychologist with experience in attention and executive function evaluation is appropriate. If you are referring for medication management, a psychiatrist or psychiatric nurse practitioner is the right choice.

Step 2: Formulate a clear referral question. Before writing the letter, clarify in your own mind what you are asking the receiving provider to do. Are you asking for a diagnostic evaluation? A treatment recommendation? Ongoing therapy for a specific condition? A medication consultation? The referral question should be specific enough that the receiving provider knows exactly what you need.

Step 3: Discuss the referral with the patient. Explain why you are making the referral, what information you will share with the receiving provider, and what the patient can expect from the evaluation or treatment. Obtain consent and document the discussion.

Step 4: Compile relevant clinical information. Gather the information the receiving provider will need — screening scores, relevant medical results, prior treatment history, and current medications. Organize this information concisely. The receiving provider does not need your entire chart — they need the information relevant to the referral question.

Step 5: Write the letter. Open with the referral question, provide the clinical context, describe the current presentation, note what you have already done, and specify any urgency. Keep the letter to one to two pages.

Step 6: Send the letter securely. Use a HIPAA-compliant method to transmit the letter — secure fax, encrypted email, or the patient's electronic health record if you share a system. Do not send clinical information via unencrypted email.

Step 7: Follow up. After a reasonable period, follow up with the receiving provider to confirm that the patient was seen and to discuss any recommendations. Close the loop — referral without follow-up is incomplete care coordination.

Common Mistakes

Failing to include a specific referral question. "Please evaluate this patient" without a specific clinical question forces the receiving provider to guess what you need. The referral question is the single most important element of the letter.

Providing too much irrelevant information. A five-page referral letter that includes the patient's complete psychosocial history, childhood memories, and detailed relationship dynamics when you are referring for a medication evaluation buries the relevant information. Be concise and focused on what the receiving provider needs for the referral question.

Providing too little information. The opposite error is also common — a referral that gives the patient's name and says "please see for therapy" provides no clinical context. The receiving provider has no idea what they are treating, what has already been tried, or what the clinical priorities are.

Not discussing the referral with the patient first. Patients sometimes arrive at the receiving provider's office confused about why they are there or what to expect. Discussing the referral in advance sets appropriate expectations and increases the likelihood of follow-through.

Failing to follow up on the referral. Sending a referral letter and never checking whether the patient was seen or what the outcome was represents a gap in care coordination. If the patient did not follow through, explore the barriers. If the receiving provider made recommendations, integrate them into your treatment planning.

Ethical Considerations

Referral letters involve sharing protected health information with another provider. While the HIPAA TPO exception generally permits this sharing for treatment purposes, best practice is to discuss the referral with the patient and explain what information will be shared. Some patients may be uncomfortable with certain information being transmitted to a new provider — for example, substance use history or trauma details. Respect these preferences when possible while ensuring the receiving provider has enough information to provide safe and effective care.

Be mindful of financial conflicts of interest. If you have a financial relationship with the receiving provider — for example, you are in the same practice, you receive referral fees, or you have a shared business interest — disclose this to the patient. Referral decisions should be based on clinical appropriateness, not financial incentives.

When referring a client to a higher level of care, such as inpatient treatment or intensive outpatient programming, be sensitive to the client's emotional response. A referral to a higher level of care can feel like abandonment or failure to the client. Frame the referral as an act of clinical responsibility and continuity, not as a discharge from your care.
