A medical excuse note or clearance is a document that verifies an individual's illness or injury and certifies that they are fit to return to work. The note is typically written by a healthcare provider, such as a physician or nurse practitioner, and includes information about the individual's diagnosis, treatment, and any restrictions or accommodations needed for the individual to perform their job duties. The note may also include the expected duration of the individual's recovery and any follow-up appointments or medical evaluations required. Medical excuse notes or clearance are commonly used in cases of short-term or long-term illnesses, injuries, or surgeries.
