Medical Consent Letter for Surgery
Hospitals require written consent before any surgery, and when the patient is a minor or incapacitated, a family member must give it. This letter records that consent clearly, with the procedure and the authorizing person named.

When and how to use this letter
Hospitals will present their own consent form on the day — this letter is for situations where you must give consent in advance or from a distance, such as when a guardian cannot reach the hospital before an urgent procedure, or when an institution requests written authorization ahead of admission. Always ask the hospital whether their own form supersedes yours; in most cases, you will still sign theirs on arrival.
Never sign without the explanation the letter describes. A valid consent requires understanding the procedure, its risks, the anesthesia plan, and the alternatives. If the doctor has not walked you through these, ask — it is your right, and the letter is only meaningful if the consent behind it is genuinely informed.
Deliver the letter to the hospital's administration or the treating doctor's office before the surgery date, and carry the original with you on the day. Keep a copy with the patient's medical file at home; consent paperwork sometimes goes missing between departments.
The point people overlook: the emergency-extension clause. Surgery occasionally reveals something unexpected once the patient is under anesthesia, and without advance authorization for immediately necessary additional measures, the team may have to wake the patient and reschedule. Discuss this clause with the surgeon so you understand its limits, and make sure your phone stays on and charged throughout the procedure — the team may still need to reach you for major decisions.
