A diagnosis letter is a formal medical document prepared by a qualified healthcare professional to officially confirm a patient's medical condition. Also known as a "proof of diagnosis letter," it is based on a thorough evaluation, including clinical observations, diagnostic tests, and the clinician's expert judgment. It serves as a critical communication tool between healthcare providers, patients, and third parties such as employers, insurance companies, and educational institutions.
A well-crafted diagnosis letter is more than a formality; it’s a vital tool that can significantly impact a patient’s life. Here’s why these letters matter:
To ensure clarity, comprehensiveness, and professionalism, a diagnosis letter should include the following components:
Clearly identify the patient at the beginning of the letter. Include their full name, date of birth, and contact information to avoid confusion.
Include your full name, title, medical license number, and the name and address of your clinic or hospital to establish authority.
Specify the date the diagnosis was made to establish a clear timeline of the patient’s condition and treatment.
State the medical diagnosis clearly and concisely, avoiding overly technical jargon that may confuse non-medical readers.
Briefly explain the symptoms, clinical findings, and diagnostic tests (e.g., lab results, imaging studies) used to arrive at the diagnosis, providing credibility and context.
Describe how the condition affects the patient’s daily life, including their ability to work or attend school, especially for accommodation or leave requests.
Outline the recommended treatment plan, including medications, therapies, or lifestyle changes, and suggest specific accommodations if applicable.
Include a statement affirming patient consent for sharing medical information, demonstrating a commitment to privacy and confidentiality.

How can I structure a medical diagnosis letter for a patient that is both comprehensive for specialist referrals and clear for them to understand?
To write a medical diagnosis letter that effectively serves both specialists and patients, structure it with clarity and precision. Begin with the patient's full name, date of birth, and the examination date. Clearly state your name, credentials, and practice information. Present the clinical diagnosis using standardized terminology (like ICD-10 codes) for the specialist, but also explain it in simple terms for the patient. Detail the clinical findings and diagnostic methods used to arrive at the diagnosis. Crucially, describe how the condition impacts the patient's daily activities or work functions, which provides essential context. Conclude with the recommended treatment plan, any necessary accommodations, and a statement confirming patient consent for sharing the information. Adopting a clear, structured template for these letters can significantly streamline the process.

What key information must be included in a diagnosis letter for an employee's workplace accommodation request to be effective?
When writing a diagnosis letter to support a patient's request for workplace accommodations, focus on the functional impact of the medical condition. While you must state the diagnosis clearly, it is more critical to describe the patient's specific limitations. For instance, instead of just stating "chronic back pain," detail the inability to sit for more than 60 minutes or lift objects heavier than 15 pounds. Outline specific, actionable accommodations, such as an ergonomic chair, modified work schedule, or reduced physical tasks. It is vital to connect the diagnosis directly to the requested accommodations, explaining why they are medically necessary for the patient to perform their job duties. Ensure the letter includes your professional credentials and contact information for verification. Consider implementing systems that help you capture these functional details during the patient encounter, ensuring your documentation is robust and fit for purpose.
My patient needs a diagnosis letter for their insurance claim. What phrasing and details will best support their claim and prevent delays?
To write a diagnosis letter that effectively supports an insurance claim, you must emphasize the medical necessity of all treatments, tests, and medications. Use precise, evidence-based language. Clearly state the diagnosis and include the date of onset and the key clinical findings that confirm it. For each recommended intervention, from physical therapy to prescription medication, explicitly state why it is medically necessary for managing the patient's condition. For example, "Physical therapy is medically necessary to restore range of motion and prevent long-term disability." Avoid vague descriptions and instead provide objective data where possible (e.g., "restricted range of motion of 20 degrees in the left shoulder"). Using a consistent and detailed template for these letters can help ensure you include all the necessary information to support your patient's claim.
